Abstract
A ball screw having a plurality of circulating devices cooperating with a plurality of spiral grooves comprises a screw, a nut and a plurality of balls. In a surface of the screw is defined at least two spiral grooves. The nut is defined with spiral grooves relative to that of the screw, in a wall between an inner diameter and an outer diameter of the nut is defined a receiving hole, and one end of the nut corresponding to the receiving hole is defined with a positioning groove. The balls are disposed in the spiral grooves of the screw and the nut. Both ends of each circulating device are formed with an opening, and a groove is formed between the openings. Thereby, a single groove circulation system is formed in the spiral grooves, which can bear bi-directional load, and is simple in structure and easy to assemble.
