Details of trouble

The input shaft rotates, but the output
shaft will not.

Damage due to overloaded gears or
shafts

The key is out of position

Scorched bearing

Poor adjustment of protective device

Incorrect wiring for the motor

Overload

The ambient temperature is too high
Damage due to overload applied to
gears, bearings, etc.

Reduce the load to the specified value

Improve the ventilation method

Damaged gears, shafts, or bearings

Repair at a specialized workshop

Deformation of the housing due to
irregular installation surface

Flatten the installation surface or use
liners for adjustment

Repair at a specialized workshop

Damaged oil seal

Scratches or abrasion of the lip contact
section

Loose tightening bolt

Tighten the tightening bolts to the proper
torque

Change the oil seal

Repair at a specialized workshop

Repair at a specialized workshop

Place the key in position

Repair at a specialized workshop

Adjust the protective device

Change the connection

The output
shaft turns
when there is
no load.

Excessive temperature rise

Oil leakage

Abnormal sound.
Excessively high vibration.

Oil leaks from the input /
output shaft sections.

Oil leaks from the joint
surface of the housing.

But it seizes up when a
load is applied.

Reverse rotation is possible.

Cause

Correction

Scorched bearing

Repair at a specialized workshop

Resonance due to insufficient rigidity of
installation base

Reinforce the installation base to
improve the rigidity

Incorrect alignment with the mating machine

Align the shaft center

Transmission of the vibration of the
mating machine to the reducer

Independently operate the reducer to
check the source of abnormal sound
