Harmonic Drive Solution

Laifual Harmonic drive (strain wave gear, harmonic gearbox, harmonic reducer) mainly consists of three parts. Which are wave generator, flex spline, cicular spline. Our harmonic drive has the characteristics of zero-backlash, low-temperature rise, low starting torque, high reliability, high load capacity, long lifetime, big speed ratio, small size, etc. Laifual drive is a top manufacturer for harmonic drive. With more than 10 years R&D experience. Supplied harmonic drive to many robotic & automation customers.

Harmonic Drive Reducer Working Principle

As a reducer, the harmonic drive gear reducer is often in status as the wave generator drives, the circular spline is fixed, and the flex spline is output end.

Both cycloidal reducer and harmonic reducers are internal gearing with small tooth number difference. The difference is that a key gear in the harmonic is flexible. The key gear needs to be repeatedly deformed with high speed, so it is relatively fragile, and its bearing capacity and life are limited. Cycloidal reducer usually uses cycloidal pinwheels. Harmonics used to use involute tooth shape. Now some harmonic gearbox manufacturers use double arc tooth shape, which is much more advanced than involute tooth shape.
