Publication number: 20200191247Abstract: A ball screw includes a screw, a nut, a plurality of balls and a ball return path. A spiral screw groove is formed on an outer peripheral surface of the screw shaft. The nut is disposed around the screw shaft. A spiral screw groove is formed on an inner peripheral surface of the nut. The balls are housed in rolling paths formed by the two screw grooves facing each other. The ball return path circulates the balls in no more than one turn of the rolling paths. A length of the ball return path between scoop-up points where the balls are scooped up from the screw groove of the screw shaft is set to a value which is from ?0.1 to +0.3 times of a diameter of the balls with respect to an integer value of a number of the balls filled between the scoop-up points.Type: ApplicationFiled: November 10, 2017Publication date: June 18, 2020Applicant: NSK LTD.Inventor: Keitaro OKA
