Title:
STRAIN WAVE GEAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/032055
Kind Code:
A1
Abstract:
A strain wave gear device (1) is provided with: a rigid internal gear (2); a flexible external gear (3) that is arranged coaxially on the inside of the internal gear (2); and a wave generator (4) that is arranged coaxially on the inside of the external gear (3), and, on the inside of the external gear (3), in addition to the wave generator (4), a brake mechanism (5) that constrains or prevents the rotation of the wave generator (4) is installed. Since the empty space on the inside of the external gear (3) is used as a space for installing the brake mechanism (5), the strain wave gear device (1) with a brake can be realized without increasing the axial length thereof. Accordingly, by using the strain wave gear device (1), an axially short, flat actuator with a brake can be realized.
