Abstract

PURPOSE: To bear both radial and thrust loads by forming one part of a female screw groove which constitutes a ball guide passage in such section as will bear a radial load and the other part in such section as will bear a thrust load.
CONSTITUTION: A ball screw has a screw 11, a nut 12, balls 13a, 13b enclosed in two spiral spaces consisting of two male screw grooves and female screw grooves provided thereon, and circulating passages 14a, 14b connected to said spaces. Then, the ball 13a in the spiral space formed with a female screw groove 16a for the nut 12 and a male screw groove 15a for the screw 11 come in contact with the screw groove at 2 stops and is arranged such that a thrust load is ready for receiving by allowing a working line 17 which passes through the contact points to decline against a central axis. On the other hand, the ball 13b in the spiral space formed with male screw groove 15b and female screw groove 16b is arranged such that a radial load is ready for receiving by allowing a working line 18 to make a right angle to the central axis.
