Abstract
The invention provides equipment for manufacturing a torque sensor shaft by forming a magnetostrictive region including a metallic glass coating in a predetermined pattern on a side face of a shaft-shaped workpiece. The shaft-shaped workpiece is rotatably attached on a conveying pallet. The conveying pallet is successively conveyed to each of work devices including a preheating device for the shaft-shaped workpiece, a thermal spraying device for forming a metallic glass coating on a side face of the shaft-shaped workpiece, a masking device configured to provide a covering corresponding to the pattern on the coating, and a shot blasting device configured to provide shot blasting directed toward the metallic glass coating including the covering. Preheating, thermal spraying, masking, and shot blasting are performed respectively on the shaft-shaped workpiece while rotating the shaft-shaped workpiece on the conveying pallet at each of the work devices. Therefore, the favorable manufacturing equipment can be provided.
