    摘要： Disclosed is an electric actuator capable of effectively absorbing shock exerted on its component part. The electric actuator has a housing, a rod cover, a piston, a feed screw, a sliding nut, two piston dampers for absorbing shock exerted on the piston, a first end damper attached to one of the opposite ends of the housing, a second end damper attached to the rod cover. The sliding nut is axially displaceable relative to the piston when the piston damper absorbs shock.

    摘要： A motor, a ball screw shaft, etc. are accommodated within a frame that forms an outer frame. Direct-acting guides are provided on both sides of a groove-shaped opening defined in the frame. The ball screw shaft is centrally disposed within the frame. A table slides along the direct-acting guides under the action of rotation of the ball screw shaft. The ball screw shaft has ball-screw splines formed over its entire length and both ends thereof supported by the motor and a bearing. The center of rotation of the ball screw shaft is brought into alignment with the centers of rotation of the motor and the bearing by balls inserted into the ball-screw splines.

    摘要： Disclosed is an actuator having a frame in which a drive source and a slider displaced under the action of the drive source are held, and an actuator arrangement comprising a plurality of actuators connected to each other by connecting devices. A beam member, which constitutes the frame, has a concave portion defined in a side thereof and the drive source is held in the concave portion. A slider base is held in the concave portion and includes the slider displaced along the concave portion. A cover is used to cover the concave portion defined in the beam member. The beam member has grooves defined in respective outer sides thereof, which have substantially T-shaped cross sections and enable other beam members to be mounted to the beam member. The grooves are defined along the longitudinal direction thereof so as to be substantially identical in structure to one another. According to the above construction, either other beam members or the actuators can be connected to one another by means of the grooves so as to assemble a desired actuator arrangement having a desired shape, thereby making it possible to place the actuator arrangement on a production line in a factory.

    摘要： An electric actuator has a body with a hole defined therein and an electric motor fixed to an end of the body. The electric motor has a rotatable shaft to which a feed screw is coaxially connected, and a feed nut is threaded over the feed screw. The hole receives an elongate cylindrical tubular member slidably fitted therein which surrounds the feed screw. The feed nut is secured to an end of the tubular member, and a support for feeding a workpiece supported thereon is fixed to the other end of the tubular member. The feed screw, which serves as a drive force transmitting shaft, is protected by the surrounding tubular member from the deposition thereon of dust, dirt, or other foreign matter and hence from unwanted shutdown or breakage.
