Abstract: In a magnetic drive linear actuator, a load attachment portion is fixed to the lower side portion of the rectangular tubular coil frame of a mover, and a light-emitting portion of a position detection portion for detecting the movement position of the mover is fixed to the upper side portion of the coil frame. The load attachment portion and the upper side portion of the coil frame are mutually coupled through beam portions bridged there between. This makes it possible to prevent or suppress the behaviors of the load attachment portion and light-emitting portion from being shifted to each other during high-acceleration driving of the mover, thereby improving the responsiveness and positioning accuracy of the linear actuator.

Abstract: A strain wave gearing has three components and a temporary-fixing jig, three components being an internally toothed gear, a cup-shaped externally toothed gear, and a wave generator. The temporary-fixing jig is securely fastened to an output shaft fixed to the externally toothed gear by a temporary-fixing bolt and is securely fastened to an input shaft fixed to a cam plate of the wave generator by a temporary-fixing bolt. The temporary-fixing jig engages with the output shaft and the input shaft and maintains the three components in an assembled state. There is no need for an operation for adjusting the positions of the three components in an operation for attaching the strain wave gearing to a motor. After the strain wave gearing has been attached to the motor, the temporary-fixing jig is removed from the strain wave gearing, wherefore less space is required for installation.

Abstract: In a strain wave gearing, both of a pulley for transmitting rotation in a direction orthogonal to a rotation central axis and an output shaft are arranged on an axial-direction first side relative to a cup-shaped externally toothed gear. The input shaft, which transmits input rotation from the pulley to the wave generator, functions as a support shaft for both the pulley and the wave generator and is supported at both ends by the first and second bearings. A mechanism for transmitting rotation from the pulley to the wave generator, and a mechanism for supporting the rotation-transmitting mechanism, can be made compact, and support strength can also be ensured.
