Background
The ball screw pair is an ideal transmission device for interconversion between rotary motion and linear motion, and has the structural characteristics that balls are arranged between screw nuts with spiral grooves so as to reduce friction. The balls are called internal circulation type in the circulating rolling process. The ball screw of internal circulation type has a reverser, the returning ball enters the reverser from the thread rolling way, and the ball is forced to pass through the screw thread to the adjacent rolling way by the reverser, so as to realize circulation. In the process, the balls roll between the reverser and the outer circle of the screw rod and cannot slide out along the roller path. Generally, 2-4 reversers are arranged on one nut and are uniformly distributed along the circumference of the nut. The circular reverser with convex keys and unable to float in the hole is called an intermittent reverser; an inverter that is circular and can float within the bore is referred to as a floating inverter. The internal circulation type has the advantages of compact radial size and good rigidity. The efficiency is high because the return roller path stroke is short and the friction loss is small.
