Title:
FLEXIBLE ENGAGEMENT GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/096347
Kind Code:
A1
Abstract:
Provided is a flexible engagement gear device wherein the transmission torque is large, and the life of an oscillator bearing can be increased. A flexible engagement gear device (100) has an oscillator (104), external gears (120A, 120B) which are disposed on the outer periphery of the oscillator (104), and can flexibly change shape, internal gears (130A, 130B) which have stiffness sufficient to internally engage the external gears (120A, 120B) with the internal gears, and oscillator bearings (110A, 110B) disposed between the oscillator (104) and the external gears (120A, 120B). The oscillator bearings (110A, 110B) are provided with rollers (116A, 116B), and retainers (114A, 114B) for retaining the rollers (116A, 116B). A load reduction region (LA) in which a radial gap (Gr) for reducing the load applied from the oscillator (104) and the external gears (120A, 120B) to the rollers (116A, 116B) is formed, is provided in an non-engagement range (SA) of the oscillator (104).
