Abstract
A strain wave gearing has a wave generator for generating a wave motion that repeatedly flexes each part in the circumferential direction of an externally toothed gear in the radial direction. The wave generator is provided with a plurality of wave-generating members arranged at positions at a prescribed angular interval along the circumferential direction of the externally toothed gear. Each of the wave-generating members is provided with an outer circumferential cam surface, rotates centered on a rotation center line that is parallel to the device center axis line, and repeatedly flexes each part of the externally toothed gear in the radial direction with a prescribed amplitude. A strain wave gearing, which is suitable for forming a large device hollow part, can be obtained.
