摘要： A ball screw and nut linear actuator incorporates an axially extending screw and a nut received on the screw to provide a helical raceway with recirculating load bearing balls. An axially extending member carried by the nut on a surface of the nut radially outboard of the raceway has ball return passages opening to the screws groove extending axially to span different turns of the screw groove. The ports lead to the ball return passages and are supplied with a liquid lubricant by a distributor system.
