Harmonic Drive Gearbox Applications
CCHN harmonic drive gearboxes can be used to optimize the shape of robots, increase precision, increase strength, improve flexibility, etc., and are widely used in industrial robots, numerical control equipment, medical instruments, military and other fields.

Tips: Causes of Bearing Damage in Harmonic Drive Gearbox
- If the cavity is not cleaned or the added grease is not clean, the wear, vibration and noise of the bearing will be increased, and the bearing raceway of the harmonic drive gearbox will be damaged, resulting in excessive temperature rise and burning of the bearing.
- Because the temperature rise of the motor body is too high, and the bearing is not replenished with grease in time, the bearing is short of oil or even burned. The mixed-use of different greases will also cause damage to the harmonic reducer bearings.
- The bearing of the harmonic drive gearbox is improperly assembled, and the inner ring of the bearing is knocked unevenly during cold assembly to wear the shaft.
- If the strain wave harmonic drive gearbox does not run for a long time, the grease will deteriorate and the bearing will rust without timely maintenance.
- Harmonic reducer bearings are affected by additional loads.
