Ratio Multiplier
These instructions must be read
thoroughly before installing or operating
speed reducers. File instructions for
future reference.
•For safe operation of any gear drive, all
rotating shafts and auxiliary components
must be shielded to conform with
applicable safety standards. You must
consider overall operational system safety
at all times.
•When using a speed reducer to raise
or lower a load, such as in hoisting
applications, provision must be made for
external braking. Under no conditions
should a speed reducer be considered
•Mounting of speed reducers in overhead
positions may be hazardous.Use of
external guides or supports is strongly
recommended for overhead mounting.
Align all shafts accurately. Improper alignment
can result in failure. Use of flexible coupling
is recommended to compensate for slight
Auxiliary drive components (such as sprockets,
gears and pulleys) should be mounted on the
shafts as close as possible to the housing to
minimize effects of overhung loads. Avoid force
fits that might damage bearings or gears.
Gear drives are nameplated for 1750 RPM
Input Speed and Class I Service. For lower
Input Speeds and other Service Classes,
consult the factory. INSTALLATION
Baldor Ratio Multipliers are ready for
installation as removed from the carton.
Each Ratio Multiplier has been filled with
Klubersynth GH6-460 synthetic lubricant
at the factory. The oil quality is sufficient
for any mounting position. The motor
shaft coupling has been prelubricated
with Kluber Q NB 50 antiseize.
Mounting Position
For maximum seal life, the Ratio Multiplier
should be mounted with the input shaft
as high as possible. Mounting the
Ratio Multiplier with the input seal
vertically down is not recommended.
If a vertically down input shaft position is
required, consult the factory. Lubrication
Oil changes are not required. Oil should
only be replaced when maintenance is
performed that requires disassembly. If
the oil is replaced, use Klubersynth GH6460. This Lubrication is suitable for a
wide temperature range (-31F to 320F).
However refer to “Operating Environment”
section for ambient operating
temperature for Baldor ratio multipliers.
(Oil capacity in fluid ounces RM1 6.2 oz.,
RM2 11 oz.)
Satisfactory performance may be obtained
with non-synthetic oils and will require more
frequent changes.
Operating Environment
Baldor Ratio Multipliers are designed to
operate in ambient temperatures of -10°F
to 100°F. The oil sump temperatures
of the Ratio Multiplier must not exceed
200°F Consult the factory for applications
requiring ambient operating temperature
outside this range.
“c” flange – hollow bore worm style:
step #1. Remove
bore plug. Position key
in Ratio Multiplier Input
Bore. Line up the key with
the keyslot and slip the
motor shaft into the Ratio
Multiplier Input Bore.
step 2. Tighten the
supplied 4 bolts with
lockwashers evenly
for a solid fit between
motor and “C” flange.
extended “c” flange with flexible coupling style:
step #1: Mount one coupling half on motor shaft so that the coupling half and end of key are flush with end
of motor shaft. (See Drawing A)
step #2: Tighten coupling setscrews. Thread locking compound is recommended on all coupling setscrews.
Measure distance from inner face of coupling to motor mounting surface. (See Drawing A)
step #3: Mount other coupling half on the reducer input shaft so the coupling end measures the same
distance to the mounting surface of the “C” flange. (See Drawing B) Tighten setscrews. Key should
be flush with shaft end. Use pipe plug opening in side of “C” flange to loosen, tighten or make any
adjustments in coupling position.
step #4: Align coupling halves and install motor.
step #5: Rotate motor to required position and tighten the supplied four bolts and lockwashers evenly for a
solid fit between motor and “C” flange. Re-install and tighten the pipe plug in the flange access hole.
