Harmonic reducers based on the strain-wave-principle
Wanshsin is a renowned supplier of planetary gearboxes and also supplies harmonic reducers.
The Wanshsin harmonic reducers are gearboxes based on the so-called strain-wave principle in which a flexible tooth ring rotates via an oval drive shaft in an annular outer tooth ring. Because the outer ring has more teeth than the flexible inner ring, the rings will move relative to each other in relative terms.
This principle is known on the market from the manufacturer Harmonic Drives.
Characteristics of the harmonic reducer are:
- very compact installation
- high gear ratio (up to 1: 120) in one stage
- low backlash (10-20 arcsec)
- low noise
Typical applications are robots, machine tools, medical industry such as body scanners and radar systems.
Wanshsin's delivery program harmonic reducers is the same as the CSF, CSG, SHG, SHD, and CSD gear units from Harmonic Drives in frame sizes 14 to 32.
