Title:
FLAT STRAIN WAVE GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/059494
Kind Code:
A1
Abstract:
This flat strain wave gear device (1) is provided with an axially arranged rigid gear (2), flexible gear (3) and wave generator (4). The flexible gear (3) forms a flat truncated cone shape, has a tooth-forming component (34) connected via a bellows-shaped cross-sectional diaphragm (32) to a rigid boss (31) which is an output shaft linking part. This flat strain wave gear device can ensure axial flexibility of the tooth-forming component (34), and can enable teeth of the flexible gear (3) to mesh favorably with teeth of the rigid gear (2) from the axial direction in each position in the tooth longitudinal direction. Local bias of the load torque in the meshing portion in the tooth-forming component (34) can also be suppressed.
