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.
