●Parallel Shaft Type
●Right-Angle Type
Oriental Motor gearheads are specially designed for easy and
direct attachment to our AC motors that have a pinion shaft. The
gearhead reduces the motor speed which increases the torque.
A large number of gear ratios are available for many applications.

Right-Angle Gearheads
Right-Angle gearheads are flange-mounted
gearheads that use worm gears and special
helical gears. They allow motors to be installed at
right angles to the axis of equipment such as belt
conveyors. They are available in hollow shaft RH
and solid shaft RA models and are ideal for
keeping equipment compact.

Features
●Right angle gearheads with mounting sizes of 80 mm (for
25W) or 90 mm (for 40 W) are available for GN pinion and
mounting sizes of 90 mm (for 60 or 90 W) are available for
GU pinion. They can be connected to all Oriental Motor AC
motors with the exception of BH, FBL2, HBL, FPW series.
●The output shaft is perpendicular to the motor shaft, so the
motor can be installed perpendicular to the axis being driven.
●Eleven available models span gear ratios are available from 3
:1 to 150：1,offering tremendous selection. The optimum
gear ratio can be selected just as with ordinary gearheads.
The maximum permissible torques are also the same as for
ordinary gearheads.
●Hollow shaft gearheads allow additional space savings and
simpler mechanism designs since they do not require
couplings for mounting. Usually, hollow shaft gearheads are
locked with a torque arm when mounted so the gearhead
does not rotate from the reactive force of the load. When
mounted with a torque arm, no centering is needed, so it is
faster to mount the gearhead on the device.

Note : Unlike most worm gear mechanisms, the right-angle gear does not have self-locking capabilities.
Gearhead Efficiency
The permissible torques shown on the following page cover most motor combinations. For motor combinations
not covered, use the efficiency value in the table below for your calculations.
When making a selection, remember that the transfer efficiency at startup is lower than at the rated speed.

Example of Mounting the Load
The diagrams below show how to mount loads depending on the shape
of the shaft. Hollow shafts are finished to an inner diameter tolerance of
H8 and machined with a key groove for mounting the load shaft. The
recommended tolerance for the load shaft is h7. Use the key provided
with the product by fastening it to the shaft. Apply a coating of
molybdenum disulfide or similar grease to the inner diameter of the
load shaft to prevent binding. Recommended load shaft dimensions are
shown below.
Stepped-down shafts
Straight load shafts
Note : If the bolt extends out more than 4 mm from the end of the hollow shaft,
no safety cover can be installed. (RH model hollow shaft gearheads
include safety covers.)

● The speed is calculated by dividing the motor’s synchronous speed (50Hz: 1600r/min) by the gear ratio. The actual speed is 2 20% less than the listed value,
depending on the size of the load.
● The efficiency of the gear assembly at startup is lower than the rating, so output torque is lower.
● All output shafts rotate opposite to the direction of motor shaft rotation.
