Title:
TORQUE MEASUREMENT DEVICE-EQUIPPED ROTATION TRANSMISSION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/033976
Kind Code:
A1
Abstract:
In order to implement a structure capable of improving the resolution of torque measurement while preventing the plastic deformation of a torsion bar (15), an input-side stopper part (61) having a rugged shape (gear shape) in a circumferential direction is provided in a portion of an input-side rotation body (55) composed of an input shaft (13) and an input gear (7), and an output-side stopper part (63) having a rugged shape (gear shape) in the circumferential direction is provided in a portion of an output-side rotation body (56) composed of an output shaft (14) and an output gear (8). The input-side stopper part (61) and the output-side stopper part (63) are combined so as to be engaged to be able to transmit torque only when the angle of torsion within the elastic range of the torsion bar (15) reaches a predetermined amount.
