Harmonic Drive Gearbox Applications
ATO 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: Harmonic Drive Gearbox Troubleshooting
- During use, the vibration of the harmonic drive gearbox increases, and the noise increases. The main reason is that the components inside the case are too worn or damaged.
- The gear tooth surface is worn, the gear shaft hole or keyway is worn; the screw hole at the bearing hole is worn; the shaft surface is worn. The precision of parts can be restored by electroplating.
In order to ensure the service life of the hard tooth surface harmonic reducer, it is necessary to strictly select the type, ensure its safety factor, and operate in strict accordance with the instructions, so as to prolong the service life of the harmonic reducer.
