Title:
SLIDING CONTACT-TYPE WAVE GENERATOR AND STRAIN WAVE GEARING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/046930
Kind Code:
A1
Abstract:
A wave generator (5) of a strain wave gearing device (1) is provided with a rigid plug (11) with an elliptical outer circumferential plug surface (12), and a ring-shaped displacement body (13) that is bent to an elliptical shape by the plug (11). The ring-shaped displacement body (13) is provided with multiple radially disposed displacing sections (15). The plug-contacting surfaces (16) of the displacing sections (15) are in sliding contact with the outer circumferential plug surface (12) and when the plug (11) rotates, the displacing sections (15) are repeatedly displaced in the radial direction. By the displacement of the displacing sections (15), a wave motion is generated in an external gear (4). The present invention is able to achieve a wave generator capable of generating wave motion in the external gear (4) with a small rotational torque.
