摘要： An actuator has a housing, a motor and a wave gear reduction drive arranged axially in the housing, and a rotational shaft extending through the centers of these portions. The rotational shaft is supported at its rear side by a first bearing and at its front side by a boss of a flexible external gear of the wave gear reduction drive via a second bearing. The rotational shaft is formed integrally on its outer peripheral portion with a cam plate of a wave generator of the wave gear reduction drive. The actuator thus configured does not require a coupling mechanism between the motor and the wave gear reduction drive and needs fewer bearings to support the rotational shaft, making it possible to reduce the axial length of the actuator.

摘要： A linear actuator with a dustproof mechanism provides reliable dustproof capability over the entire stroke of the actuator. A linear actuator 100 with a dustproof mechanism includes a ball screw, a movable stage 4 including a ball screw nut that engages the ball screw, the movable stage capable of making linear reciprocating motion in the axial direction of the ball screw in response to rotary motion of the ball screw, a housing member 2 disposed to cover at least the ball screw, openings 27, 28 formed in the housing member 2 along the path along which the movable stage 4 travels, and dustproof belts 29, 30 disposed inside the housing member 2 to block the openings 27, 28. The linear actuator 100 with a dustproof mechanism further includes end plate covers 105a, 105b that cover both ends of the housing member 2 and hence has high dustproof performance.
