Claims

[Claims for Utility Model Registration] (1) Torque sensors 10, 20, 30, 40 for detecting the torque of the rotating shaft 1 are It has a cylindrical shape that is concentrically exteriorized and fixed to the rotating shaft 1 only at both ends in the axial direction, and detection thin parts 17, 27, 37, and 47 along the cylindrical direction are formed in the central part in the axial direction. sensor parts 11, 21,
31, 41, and the sensor section 11, 21, 31, 4
1 through bearings 12, 22, 32, 42, and supports the slip rings 13, 23, 33, 43 concentrically with the detection thin portions 17, 27, 37, 47; 34, 44, and strain gauges 15, 25, 35, 45 attached to the detection thin-walled portions 17, 27, 37, 47 and electrically connected to the slip rings 13, 23, 33, 43. torque sensor. (2) The torque sensor according to claim 1, wherein the strain gauges 15, 25, 35, and 45 are constituted by a pair of strain gauges corresponding to the normal rotation direction and the reverse rotation direction of the rotating shaft 1. (3) The torque sensor according to claim 1 or 2, wherein the sensor portion 21 and the collets 28 formed at both ends thereof are reduced in diameter by tightening a nut 29 and fixed to the rotating shaft 1. (4) The sensor part 31 is fixed to the rotating shaft 1 by reducing the diameter of a diameter-reduced part having radial slits 38 formed at both ends thereof by fitting a shrink-fit ring 39. Torque sensor listed.
