Title:
STRAIN WAVE GEARING AND WAVE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2017/006443
Kind Code:
A1
Abstract:
A wave generator (5) of a flat strain wave gearing (1) has a first plug (11), a second plug (12), a first bearing (13) fixed to an ellipsoidal external peripheral surface (11a) of the first plug (11), a second bearing (14) fixed to an ellipsoidal external peripheral surface of the second plug (12), and an Oldham coupling (15) for coupling the first and second plugs (11, 12) together. It is possible to prevent or minimize any decrease in service life and strength of the constituent components that occurs with increases in load caused by misalignment between the first and second bearings (13, 14), and misalignment of the wave generator (5) with a stationary-side internally toothed gear (2) and an output-side internally toothed gear (3).
