Motor driven axial actuator

摘要

An electric motor (6) is coupled through reduction gears to engage with a gear (38) formed on the outer surface of the cylindrical coupling (39). This transmits linear motion to an output shaft (5). A support (2) houses a nut screw coupling (40), in which a double acting ball thrust bearing (42) is integrally mounted between two opposite faces. Rotation of the coupling and a screw shaft (41), formed on the output shaft, creates axial movement of the shaft.
