EQUIPMENT AND METHOD FOR MANUFACTURING OF TORQUE SENSOR SHAFT Russian patent published in 2019 - IPC G01L3/10 H01L41/12 H01L41/47 B23Q7/14 C23C4/08 C23C4/129 

FIELD: physics.

SUBSTANCE: invention provides equipment for making a shaft of a torque sensor by forming a magnetostriction region, which includes a metal-based coating with a given pattern on the side surface of a shaft-like workpiece. Shaft-shaped billet is attached with possibility of rotation on transportation device. Transporting device is successively transported to each of working devices, including device for preliminary heating for shaft-like workpiece, thermal spraying device for forming a metal-based coating on the side surface of a shaft-like workpiece, concealment device configured to provide an upper coating layer corresponding to the pattern on the coating, and a blast cleaning device configured to provide a shot blasting aimed at the metal glass-based coating, which includes an upper coating layer. Preliminary heating, thermal spraying, masking and shot-blasting are performed respectively on shaft-like blank during rotation of shaft-like billet on transportation device in each of working devices. Suitable production equipment can therefore be provided.

EFFECT: technical result is improved characteristics of torque detection.
