摘要： The reinforced lead screw has a hollow, elongate reinforcing rail surrounding a lead screw and a nut-bearing movable along the reinforcing rail. The nut-bearing has a portion projecting through a slot in the reinforcing rail and includes threads to engage the threads on the lead screw such that when the lead screw is rotated in either direction, the nut will translate along the rail. The rail may be provided with a sleeve-bearing which, in combination with the rail, serves not only as a guide for movement of the nut but lateral support for the lead screw.

摘要： Varying fluid pressure varies the thickness of an elastic spacer between ball nuts of the ball screw. The spacer thickness determines opposed axial forces applied to the ball nuts. During a high-speed excursion of the screw, pressure in the elastic spacer is reduced, thus reducing friction between the ball nuts and the screw. When the screw is being fine positioned for precise operation, pressure in the elastic spacer is increased, thereby urging the ball nuts apart to eliminate play in the ball screw.
摘要翻译：不同的流体压力会改变滚珠丝杠球螺母之间弹性垫片的厚度。间隔件厚度确定施加到球螺母的相反的轴向力。在螺杆的高速偏移期间，弹性间隔件中的压力减小，从而减小滚珠螺母和螺钉之间的摩擦。当精确定位螺钉精确操作时，弹性垫片中的压力增加，从而推动球形螺母分离，以消除滚珠丝杠的冲击。
