Zusammenfassung:A ball screw includes a screw, a nut, and at least one ball bearing. The screw includes a first helical tooth helically protruding from an outer surface of the screw. A ball groove is defined between adjacent portions of the first helical tooth. The nut includes a second helical tooth helically protruding from an inner surface of the nut. The nut is sleeved on the screw. A rolling groove is defined between adjacent portions of the second helical tooth. The first helical tooth occludes with the rolling groove. The second helical tooth occludes with the ball groove. The first helical tooth and the second helical tooth are alternately helically spaced. The first helical tooth and the second helical tooth cooperatively define a loading groove for receiving the at least one ball bearing.
