2. General

FRIEDRICH unbalance exciter machines are designed for operation in the interior of oscillating machines, sieving machines or other vibration equipments with particularly high payloads and/or very high transport performance.

The unbalance exciter machines consist of a robust cast iron housing with two shafts connected by gearwheels housed in generously proportioned special roller bearings with increased carrying force and bearing play. Lubrication of the bearings and gearwheels is carried out by a combination of immersion in oil and oil mist lubrication.

Centrifugal weights are fitted on the end of each shaft. Up to 12 additional weights of steel or lead can be added to these depending on the use and required conveyor capability.

The centrifugal weights linked by force synchronization are set into operation in opposing directions by an external standard drive motor via a propeller shaft. The propeller shaft is linked via a connection piece with a centrifugal weight from the long shaft. In contrast to unbalanced motors, unbalance exciter machines do not experience transverse vibrations when starting up or coasting due to asynchronous running.

There is the possibility of deploying speed-adjustable drive motors when using FRIEDRICH unbalance exciter machines in a regulated vibration equipment. Pole changing motors and motors with electric speed adjustment can be used or a variable speed gear inserted between the unbalance exciter and the standard revolution engine.

As rotary motors, all commercially normal motors of 50 Hz and 60 Hz may be used at the stated voltages. Pay attention not to exceed the highest permissible revolutions (see chapter

11. Technical data).

All FRIEDRICH unbalance exciters are put through an internal test run in our factory prior to delivery.

5. Transport

In order to avoid danger to persons and damage to the unbalance exciter, the appliance should be transported with the necessary care. As well as the following points, general and local health and safety rules must be observed.

The following is of special importance:

•

When transporting out of Europe, the centrifugal weights must be secured or

•

dismounted, otherwise the bearings may be damaged because of mechanical shocks.

The correct use of transport and lifting devices must be ensured.

•

When transporting unbalance exciters on pallets, make sure they cannot tip over.

•

Only DIN 580 ring bolts must be used for installing the unbalance exciter. Ropes, shackles, etc. may only be fitted to these ring bolts.

•

Lifting gear must be approved, undamaged and suitable for transport.

•

No additional weight may be fitted to the exciter as the ring bolts are only designed for the exciter`s own weight.

•

For safety reasons, devices for lifting the unbalance exciter must have double the lifting capacity of weight of the unbalance exciter.

•

The unbalance exciter may only be placed on its footing.

•

All transport damage must be reported to the manufacturer. Special care must be taken to ensure bearing surfaces and protective covers are undamaged.

It is not allowed to use protective covers, shafts or centrifugal weights for suspension of

the unbalance exciter.

Heavy knocks or falls will damage the bearings in the exciter and reduce the exciter`s life span. The centrifugal weights and the shafts may not come into contact with the lifting device. Do not use damaged exciters.

•

In the case of bolts prohibiting the use of a torque key due to space restrictions, suitable steps must be taken to achieve the necessary torque. Hydraulic screwdrivers must be used if in doubt (e.g. PLARAD)

•

The bolts` torque must first be checked after 40 operating hours. Further checks must be carried out every 1000 hours.

•

The unbalance exciter must be filled up with the necessary amount of oil in accordance with chapter 16 - "Oil level chart" and as per the installation position.

•

The unbalance exciters are not supplied with oil!

• The ventilation plug must always be situated on the uppermost place of the

unbalance exciter.

Important: if improper bolts, nuts and torques are used, the unbalance exciter may unfasten and cause huge damages.

Possible danger for life!

Important: Note that most malfunctions and breakdowns occur due to incorrect or

loose bolt fittings!

6.4 Assembling propeller shaft and drive motor connection piece

The propeller shaft and the connection piece are fitted between the unbalance exciter and the drive motor.

FRIEDRICH Schwingtechnik does not deliver the propeller shaft and the connection piece to the drive motor as standard.

6.5 Assembling the protective boxes

The protective boxes must be assembled prior to taking the unbalance exciter into use.

The fitting locations on the unbalance exciter and the protective boxes must be cleaned prior to assembly.

The following sequence must be observed on installation:

•

Both main segments are fitted with the lower closing sheets first.

•

The four plates are then placed over the slots. Make sure that a shorter plate is fitted to the side on which the connecting flange is mounted. This should be mentioned when ordering coupled unbalance exciters or a shorter plate ordered separately. Operation, including test runs are not permitted without side plates and will release FRIEDRICH Schwingtechnik from any liability.

•

The cover of the propeller shaft must be assembled. This is not supplied with the protective box.

Important: The protective box must be completely assembled to be enough rigid.

Otherwise, damage to the protective box cannot be excluded.

- 13 -

TK-R0-071119DA


All bolts must be assembled without gaps and tightened up using a torque screw. The values for this are to be taken from table.

The bolts` torque must first be checked after 40 operating hours. Further checks must be carried out every 1000 hours.

Use only original parts provided by FRIEDRICH Schwingtechnik, otherwise mechanical and physical injury may occur.

The unbalance exciter may not be taken into use without a completely assembled protective box. This also applies to test runs. The protective box protects against malfunction of the unbalance exciter as well as from rotating parts. Operation without the protective box will release FRIEDRICH Schwingtechnik from any liability.

6.6 Drive

FRIEDRICH Schwingtechnik does not include the drive motor in the delivery.

Both electrical motors and hydraulic motors can be used. The hydraulic motors must provide slow start, The motors can be connected with the unbalance exciter via a propeller shaft or a

V-belt.

Note the following on the design of the unbalance exciter drive motor for the oscillating machine provided:

•

Please see chapter 11 - "Technical data" for the electric drive motor required. The fastening torque in the range 0-300 min

-1

must be 2.5 times the nominal torque.

•

Please see chapter 11 - "Technical data" or the type plate for the highest permitted range.

Important:

•

The minimum range n min

may only fall short of 500 min

-1

with written permission from

FRIEDRICH Schwingtechnik.

•

The maximum range n max

in accordance with chapter 11 may only be exceeded with written permission from FRIEDRICH Schwingtechnik.

•

•

Failure to observe this may result in material or physical damage.

The falling short or exceeding of permissible ranges without prior written permission will release FRIEDRICH Schwingtechnik from any liability.

After switching off the drive motor, the exciter goes through the machine's frequency range and outlet vibration occur. Thi will lead to a slowing down of the transported material or vibrating of the oscillating machine. These undesired outlet vibrations can be avoided to a large extent by slowing down the motor whereby the brake may be operated at will.

FRIEDRICH Schwingtechnik recommends braking via a DC brake.

The braking torque must not be greater than the motor's starting torque.

The unbalance exciter may only be started up if the oscillating machine is at a complete standstill.

- 14 -

TK-R0-071119DA


6.7 Electrical connection

Electrical connection of the unbalance exciter drive motor may only be carried out by authorized specialist personnel according to the regulations and standards applying at the installation location.

On the ground of safety reasons an emergency circuit breaker must be used.

Important: Earth the drive motor according to the relevant protective regulations.

7. Testing guidelines

Important: Oscillating machines may in principle only be switched on at a standstill to avoid vibrations in the resonance range.

Check the following points before commencing the test run:

•

•

Free movability of all vibrating parts.

Proper oil and grease filling for the driving components according to details in chapter 15

- "Selection of available gear oils" and chapter 16 - "Oil level chart".

•

Installation location of the unbalance exciter within permissible environmental temperatures of -40°C and +50°C.

The test run may only be started from a local control station so intervention is possible at any time in the event of physical or material danger. An acoustic and if necessary, a visual signal of sufficient length must be given before starting the unbalance exciter.

The unbalance exciter should initially run one to two hours unloaded. The machine can be taken into use under load after checking the bolts for secure seating. Ensure the maximum operating temperature of +80°C is not exceeded.

The unbalance exciter may not be taken into use without a completely assembled protective box. This also applies to test runs. The protective box protects against malfunction of the unbalance exciter as well as from rotating parts. Operation without the protective box will release FRIEDRICH Schwingtechnik from any liability.

8. Storage and internal preservation

After successful finishing of the test run performed on our testing stand, all the unbalance exciters are given preservation for at least 12 months.

It is intended to store the exciters inside closed dry stores under normal environmental conditions.

In case of aggressive, moist environmental conditions, e.g. in tropics, storage life is reduced to 6 months.

When using an unbalance exciter after long time of inactivity, it is not necessary to wash it out. It must be filled with oil according to tables 8.1– 8.4. Free movement of the shafts must be checked by hand.

If the shafts are not free to move, we recommend to let the unbalance exciter dismantle and clean at the producer.

If an unbalance exciter should be stored also after expiration of the storage life, you must keep to the following way.

Fill up the unbalance exciter with oil and rotate the shafts by hand. After that, get the oil out again.

If vapour proof packaging is used, it is absolutely essential that as much of the solvent as possible be evaporated from the interior. It is advisable not to seal available ventilation devices for transport - including sea transport - and subsequent storage. Packaging must be agreed with the supplier or the packaging company as regards destination and storage time.

9. Alteration of swing

The unbalance exciter machines have two gearwheel force-synchronized shafts fitted with unbalances. The circulating masses produce a circulating radial power F of the same frequency on both shafts. An alternating force of value F res

= F

1

+ F

2

in the direction of the exciter stand is produced due to the inverse synchronous circulation of the imbalances. An important characteristic for the selection of unbalance exciters is the so-called "static torque".

The static torque of unbalance exciters is defined as the weight of all unbalances multiplied by the radius of the centre of gravity. FRIEDRICH Schwingtechnik uses working torque instead of static torque. This is calculated by doubling the static torque. Working torque is normally expressed in [kgcm].

- 16 -

TK-R0-071119DA


Fig. 1

The amplitude of oscillation of vibrating movement of the vibration device is calculated from the unbalenced exciter’s working torque and the weight of the vibrating parts on the vibration device as follows :

Working torque [kgcm]

Swing = —————————————— = 2 * Amplitude [cm]

Mass of oscillating parts [kg]

The oscillation device’s static and thus working torque can be altered in stages with the machine at standstill by installing and removing additional weights. Please see table 6 -

"Working torque according to the additional weights" for the grading of the additional weights. By altering the swing, there is a possibility of altering the throughput of the vibration device.

Chapter 10 - "Removal and installation of additional weights" gives information on changing additional weights.

Table 6 shows the amount of working torque depending on the number and position of additional weights. This table shows installed additional weights by complete circles.

The working torque stated shows an individual unbalance exciter. The oscillating machine’s entire working torque is calculated by the addition of the working torque of all added unbalance exciters.

If the centrifugal force is to be altered, proceed as described in chapter 10 -

"Installation and removal of additional weights".

The additional weights must be installed symmetrically to the centrifugal weights’centreline. The same number of the same additional weights in the same positions are to be installed in all centrifugal weights.

- 18 -

TK-R0-071119DA


In principle, one must be careful to adjust the working torque as low as possible to achieve as high a shelf life of the unbalance exciter and the machine as possible.

Important: Ensure the centrifugal force is equally adjusted on all unbalance exciters if several unbalance exciters are to be used on one oscillating machine.

Switch off the oscillating machine immediately if an unbalance exciter goes down during operation; it may only be operated together with all unbalance exciters.

Replacement unbalance exciter

On installation, it is advisable to compare the mounting of the additional weight with an unbalance exciter to be connected with a propeller shaft in order to ensure the same additional weight mounting in number and position has been installed in all centrifugal weights.

10. Removing and installing additional weights

Removing and installing additional weights are carried out like all works on the vibration device when the machine is at standstill. Ensure the machine cannot be switched on by accident by disconnecting the drive motor.

Important: When using and working with the unbalance exciter, its centrifugal weights may turn over unexpectedly. There is a danger of knocking or pressing.

It is strongly recommended that the number or type of additional weights on all centrifugal weights be changed symmetrically.

Important: Install the same number of additional weights in the same position on all four centrifugal weights!

Additional weights of steel or lead are available for unbalance exciter machines.

It is imperative to stick to the selection of additional weights according to specification!

10.1 Removing additional weights

Check to see whether there is movement on the centrifugal weights when removing additional weights. There is a danger of knocking or pressing.

•

•

•

Commence with removal of additional weights on the long shaft.

Drive the spring pin radially into the additional weight.

Turn the centrifugal weights so there is no overlap of the additional weights with the centrifugal weight on the short shaft.

•

•

Remove the additional weight from the exciter housing by lightly tapping it.

Rotate the centrifugal weights on the short shaft so that the centrifugal weights on the cover of the unbalance exciter machine can be removed using a snap through.

•

The spring pins in the additional weights must be removed immediately.

Important: if an additional weight with a hammered in spring pin should be used again, you can hammer a second spring pin without possibility to remove the additional weight later.

13. Lubrication instructions

Important: Unbalance exciter machines are delivered without oil. Before taking into use, fill with oil in accordance with the oil level and oil type charts.

Important: The dipstick is only used to check the oil level and must again be replaced with a screwed sealing plug for operating the unbalance exciter.

Important: The operation of unbalance exciters is only permitted if the shafts are in a horizontal position.

Please follow the information in the following chapters:

14. Oil change intervals

15. Selection of available gear oils

16. Oil level chart

Important: Only fill or refill with oil after the unbalance exciter or its motor has been switched off and measures have be taken to prevent accidental or unauthorized switching on.

Otherwise, there is a danger of knocking or pressing!

Unbalance exciters are provided with several screwed sealing plugs. The ventilator plug must be fitted above the unbalance exciter oil level, as high as possible .

A screwed sealing plug is replaced with a ventilator plug. Depending on the installation position, one of these screwed sealing plugs is to be selected as an oil-drain plug and one as an oil filler plug. The screwed sealing plug at the lowest point should be chosen as the oil-drain plug and the easiest to

- 22 -

TK-R0-071119DA


access is best selected as the oil filler plug. All the screwed sealing plugs are provided with a magnet for extracting metal debris from the gearing out of the oil bath occuring during the initial operation period.

The seal rings according to DIN 7603 must be replaced each time the screwed sealing plugs are loosened. There is otherwise the risk of oil leaking and thus damage to the

unbalance exciter!

Only high quality doped oils in accordance with DIN 51519 and DIN 51502 are to be used.

If an unbalance exciter is operated using a certain oil from a certain manufacturer and the intention is to change to the same quality oil from a different producer, we recommend the unbalance exciter be completely drained and only then filled up with the new oil as oils are not always mixable due to oil additives that differ according to producers.

The oil level depends on the installation situation of the unbalance exciter and is shown in chapter 16. It is important that a quantity of oil should always be visible up to the middle of the dipstick in the unbalance exciter’s housing.

Too much oil in the housing can lead to an oil blockage leading to overheating and damage

• to the bearings. Moreover the oil runs out. On the other hand, too little oil will lead to seizure and damage to the gearing and the roller bearings.

•

The oil level should be checked via the dipstick about half an hour after switching off the vibration device.

Important! The oil level should be checked once a month.

•

When changing the oil, make sur that as much old oil is removed as possible and the metal debris cleaned from the magnetic oil-drain plug.

•

When filling with oil, ensure that no dirt particles get into the ubalance exciter. Use a funnel with finely woven screen cloth.

Before the appliance is taken into use, check the oil-drain plug and the oil sealing plugs are seated firmly. This should be repeated after 40 hours and later at longer intervals.

- 23 -

TK-R0-071119DA


14. Oil change intervals

We recommend the following oil change intervals:

•

•

•

First oil change after ca. 500 operating hours, no later than three months

Second oil change after ca. 1,000 operating hours, no later than six months

All other oil changes after 1,000 operating hours

The above oil change intervals are reference values. These intervals can be reduced or extended if necessary, according to environmental conditions. Exact oil change intervals can be set on consultation with the oil supplier and the respective oil checks can be carried out by taking occasional samples. i

The oil should be changed at shorter intervals if the oil is heavily soiled by unfavourable operating conditions by the time the first oil change is carried out. More frequent oil

changes increase the life span of the unbalance exciter.

15. Selection of used gear oils

Gear oil with required viscosity is determined according to table 7 depending on environmental temperatures.

16.1 How to understand the following angle indications

•

Depending on various mounting options of the unbalance exciters, there are possible

• various angles of installation, where the dipstick must be used to ensure correct oil level.

Warning! Angle from horizontal plane is decisive, you must add angle of the girder and tilt angle of the machine.

•

Warning! The illustrated position for the dipstick is an example only. Correct positions are mentioned in the tables.

•

The ventilator plug must be fitted as high as possible.
