Title:
TORQUE DETECTION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/217298
Kind Code:
A1
Abstract:
Provided is a torque detection apparatus that is capable of performing stable torque detection by means of a simple mechanism without any need to perform mechanical adjustment during initial setting. A torque detection apparatus (1) has an outer ring (2) and an inner ring (3) that are rotatable against each other, and detects torque applied between the outer ring (2) and the inner ring (3). This torque detection apparatus has an elastic member (4) that directly or indirectly connects the outer ring (2) and the inner ring (3) and that is deformed accompanying the rotational displacement of the outer ring (2) and the inner ring (3). An angle sensor (40) detects the rotational angles of the outer ring (2) and the inner ring (3). A torque acquisition means (10) acquires torque from the rotational angles detected by the angle sensor (40).
