Drawn: Verified: 2018-03-26 Pz/No 2018-03-26 Pz Replacing: Replaced by: KTR-N dated 2017-11-30 ROTEX® GS HP Operating/Assembly instructions 2 KTR-N Sheet: Edition: 45710 EN 5 of 15 2 Advice ® The ROTEX GS HP coupling was developed for a backlash-free power transmission and easy plug-in assembly. This backlashfree power transmission arises in the area of prestress (see illustration 2). The big surface contact results in a lower surface pressure on the elastomer. Consequently the elastomer can be overloaded many times with no wear/deformation. Safe operation in the range of prestress is ensured, because the coupling operates according to the principle of positive-locking rubber spring prestress with high damping features. The cam and pocket element are machined with special accuracy. Illustration 2: Prestress of elastomers The elastomers are inserted in the pocket element. The cam element is inserted in the pocket element with a small amount of prestress, resulting in the necessary backlash-free power transmission. The elastomers compensate for displacements. An external deformation is limited by the shape of pocket elements, ensuring a smooth operation even with bigger masses to be accelerated (e. g. machine tables, articulated arms, etc.). 2.1 General advice Please read through these operating/assembly instructions carefully before you start up the coupling. Please pay special attention to the safety instructions! ® In order to ensure the operating principle of ROTEX GS HP and avoid early wear of the coupling, a corresponding operating factor „SB“ has to be considered for the selection, each depending on the application (see catalogue). Temperatures and shocks are provided with the corresponding factors, too (see catalogue). The operating/assembly instructions are part of your product. Please store them carefully and close to the coupling. The copyright for these operating/assembly instructions remains with KTR. 2.2 Safety and advice symbols STOP !

You may be seriously hurt by rotating parts. Please make absolutely sure to read through and observe the following safety indications. All operations on and with the coupling have to be performed taking into account "safety first". Please make sure to switch off the power pack before you perform your work on the coupling. Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on or removing the fuse for current supply. Do not reach into the operating area of the coupling as long as it is in operation. Please secure the coupling against accidental contact. Please provide for the necessary protection devices and covers. 2.4 Intended use You may only assemble, operate and maintain the coupling if you have carefully read through the operating/assembly instructions and understood them had technical training are authorized by your company The coupling may only be used in accordance with the technical data (see chapter 1). Unauthorized modifications on the coupling design are not admissible. We will not assume liability for any damage that may arise. In the interest of further development we reserve the right for technical modifications. ® The ROTEX GS HP described in here corresponds to the technical status at the time of printing of these operating/assembly instructions. 2.5 Coupling selection ! For a long-lasting and failure-free operation of the coupling it must be selected according to the selection instructions (following DIN 740, part 2 with specific factors) for the particular ® application (see catalogue drive technology "ROTEX GS"). If the operating conditions (performance, speed, modifications on engine and machine) change, the coupling selection must be reviewed. Please make sure that the technical data regarding torque refer to the elastomers only. The transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his responsibility. For drives subject to torsional vibrations (drives with cyclic stress due to torsional vibrations) it is necessary to perform a torsional vibration calculation to ensure a reliable selection. Typical drives subject to torsional vibrations are e. g. drives with diesel engines, piston pumps, piston compressors etc. If requested, KTR will perform the coupling selection and the torsional vibration calculation. 2.6 Reference to EC Machinery Directive 2006/42/EC The couplings supplied by KTR should be considered as components, not machines or partly completed machines according to EC Machinery Directive 2006/42/EC. Consequently KTR does not have to issue a declaration of incorporation. For details about safe assembly, start-up and safe operation please refer to the present operating/assembly instructions considering the warnings. Please observe protection note ISO 16016.

The features of the elastomers remain unchanged for up to 5 years with favourable storage conditions. ! The storage rooms must not include any ozone-generating devices like e. g. fluorescent light sources, mercury-vapour lamps or electrical high-voltage appliances. Humid storage rooms are not suitable. Please make sure that condensation is not generated. The best relative air humidity is less than 65 %. 3.2 Transport and packaging ! In order to avoid any injuries and any kind of damage please always make use of proper transport and lifting equipment. The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise contractually agreed, packaging will follow the in-house packaging specifications of KTR. 4 Assembly The coupling is generally supplied in individual parts. Before assembly the coupling has to be inspected for completeness. 4.1 Components of the coupling Features of standard elastomers 98 ShA (PUR) 1) (black) 24 - 55 PUR Elastomer hardness (Shore) Size Material Marking (colour) 1) Other elastomer hardness on request Please observe protection note ISO 16016.

Consequently there is no need for subsequent screwing and the respective mounting holes in the housing. The pegs on the elastomer prevent a contact of the elastomers on the cam or pocket element over the full surface. Observing the distance dimension E, the ability for displacement of the coupling is ensured in this way. All elastomers are chamfered on the face which allows for blind assembly. When the cam and pocket element are ® shifted together with the elastomer of ROTEX GS HP, an axial mounting force is generated resulting from the flexible prestress of the elastomer. This assembly force varies depending on the coupling size, elastomer hardness and machining tolerances. The axial insertion force is offset after having shifted together the cam and pocket element and consequently does not mean any risk of axial load on the adjacent bearings. The mounting force can be reduced by lightly greasing or lubricating the elastomer or the cam or pocket element. For this purpose please only use oils and greases on a mineral oil basis without any additives. Lubricants on a silicone basis (e. g. Optimol Optisit WX) or vaseline have proven their worth, too. Please observe protection note ISO 16016.

If these figures are disregarded, the coupling may tear. Rotating particles may cause danger to life. Bores machined or remachined by the customer have to observe concentricity or axial runout, respectively (see illustration 4). Please make absolutely sure to observe the figures for Ø dmax. Carefully align the cam or pocket element when the finish bores are machined.. Illustration 4: Concentricity and axial runout 1) The max. bore for each taper must be considered with remachining. ! The customer bears the sole responsibility for all machining processes performed subsequently on unbored or pilot bored as well as finish machined coupling components and spare parts. KTR does not assume any warranty claims resulting from insufficient remachining. 4.4 Assembly of the coupling We recommend to inspect bores and shafts for dimensional accuracy before assembly. Please note the manufacturer’s instructions regarding the use of detergents. ! Heating the cam or pocket elements lightly (approx. 80 °C) allows for an easier mounting on the shaft. STOP ! Touching the heated cam or pocket elements causes burns. Please wear safety gloves. With the assembly please make sure that the distance dimension E (see table 1) is observed to allow for axial clearance of the coupling while being in operation. Disregarding this advice may cause damage to the coupling. ® The power transmission of the ROTEX GS HP is frictionally engaged. The necessary surface pressure is transmitted via the clamping ring with internal taper to the external taper of the cam or pocket element and consequently to the shaft. The friction torques specified in table 2 consider a fit pair H6/k6. With a bigger fit clearance the friction torques specified in table 2 are reduced. The stiffness and dimensions of the shafts (here specifically hollow shafts) have to be dimensioned such that sufficient safety against plastic deformation is ensured. This may roughly be reviewed as per the following criterion. Please observe protection note ISO 16016.

For a detailed calculation please contact KTR’s engineering department. ! Do not lubricate taper surfaces of the cam or pocket element with initial assembly, since the components are coated with lubricant when being supplied. For relubrication, for example after disassembly, the multipurpose fat Molykote G Rapid plus should be used on the taper surfaces. Only use thin-fluid oil for the threads of the clamping screws. Clean and degrease the bore of cam and pocket element and the shaft. Lightly untighten the clamping screws and pull the clamping ring down from the cam or pocket element only marginally to make sure that the clamping ring is installed loosely. Shift the cam or pocket element onto the shaft. The dimension l3 or l4 should at least be observed (see table 1). Tighten the clamping screws evenly crosswise gradually to the tightening torque specified in table 2. Repeat this process until all clamping screws have reached the tightening torque. Illustration 5: Assembly Pocket element with clamping ring No gap allowed between cam or pocket element and clamping ring after tightening of all clamping screws (see illustration 6). ! If the clamping screws are not tightened at the correct tightening torque, there is the risk of a) a fracture of the cam element and plastic deformation with a too high tightening torque T A b) early slippling, untightening of the screws with a too low tightening torque T A Illustration 6: Block assembly Please observe protection note ISO 16016.

During every revolution every screw may only be unscrewed by half a turn. Unscrew all clamping screws by 3 - 4 pitches. Screw the setscrews into the respective extraction threads until contact (setscrews are not part of the scope of delivery). The clamping ring is released by tightening the setscrews in the pull-off threads evenly gradually and crosswise. If these hints are not observed, the operation of the coupling may be affected. !

Only use thin-fluid oil for the threads of the clamping screws. 4.6 Displacements - alignment of the couplings The displacement figures specified in table 3 provide for sufficient safety to compensate for external influences like, for example, thermal expansion or foundation settling. ! In order to ensure a long service life of the coupling, the shaft ends have to be accurately aligned. Please absolutely observe the displacement figures specified (see table 3). If the figures are exceeded, the coupling will be damaged. The more accurate the alignment of the coupling, the longer is its service life. Please note: The displacement figures specified in table 3 are maximum figures which must not arise in parallel. If radial and angular displacements arise at the same time, the permissible displacement values may only be used proportionally (see illustration 9). Please inspect with a dial gauge, ruler or feeler gauge whether the permissible displacement figures specified in table 3 can be observed. Please observe protection note ISO 16016.

Finally the coupling protection against accidental contact must be fitted. It is required in accordance with DIN EN ISO 12100 (Safety of Machinery) and directive 2014/14/EU and must protect against access with the little finger falling down of solid foreign objects. The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with DIN EN ISO 13857. The cover must be electrically conductive and included in the equipotential bonding. Bellhousings (magnesium share below 7.5 %) made of aluminium and damping rings (NBR) can be used as connecting element between pump and electric motor. The cover may only be taken off with standstill of the unit. During operation of the coupling, please pay attention to different operating noise vibrations occurring. ! 6 If you note any irregularities with the coupling during operation, the drive unit must be switched off immediately. The cause of the breakdown must be specified by means of the table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential breakdowns specified can be hints only. To find out the cause all operating factors and machine components must be considered. Breakdowns, causes and elimination ® The failures specified below can lead to a use of the ROTEX GS HP coupling other than intended. In addition to the specifications given in these operating and assembly instructions please make sure to avoid such failures. The errors listed can only be clues to search for the failures. When searching for the failure the adjacent components must generally be considered. General failures with improper use: Important data for the coupling selection were not forwarded. The calculation of the shaft-hub-connection was not considered. Coupling components with damage occurred during transport are assembled. When mounting the cam or pocket element in a heated condition, the permissible temperature is exceeded. The clearance of the components to be assembled is not coordinated with one another. Tightening torques have been fallen below/exceeded. Components are mixed up by mistake/assembled incorrectly. Wrong or no elastomers are inserted in the coupling. No original KTR components (purchased parts) are used. Old/already worn out elastomers or those stored for too long are used. Maintenance intervals are not observed.

Metal Any metal components have to be cleaned and disposed of by scrap metal. Nylon materials Nylon materials have to be collected and disposed of by a waste disposal company. 8 Maintenance and service ® ROTEX GS HP is a low-maintenance coupling. We recommend to perform a visual inspection on the coupling at least once a year. Please pay special attention to the condition of the elastomers of the coupling. Since the flexible machine bearings of the driving and driven side settle during the course of load, please inspect the alignment of the coupling and re-align the coupling, if necessary. The coupling parts have to be inspected for damages. The screw connections have to be inspected visually.
