发明名称 Electric actuator
摘要 An electric actuator includes a hollow actuator housing, an electric motor connected to the hollow actuator housing, a feed screw shaft coupled to the drive shaft of the electric motor, for transmitting rotational drive power from the electric motor, and a spline tube disposed in the hollow actuator housing in surrounding relationship to the feed screw shaft and held in engagement with the feed screw shaft, for displacement axially with respect to the hollow actuator housing with the rotational drive power transmitted by the feed screw shaft. Since the feed screw shaft is surrounded by the spline tube, dust and dirt particles are prevented from being deposited on the feed screw shaft.
