摘要： A roller screw of the present invention has a screw shaft 1 having a roller rolling surface 1a spirally formed with a lead on an outer surface thereof; a nut 2 having a roller rolling surface 2a spirally formed on an inner surface thereof to face the roller rolling surface 1a of the screw shaft 1; and a plurality of rollers 4 arranged in a rolling path 3 between the roller rolling surface 1a of the screw shaft 1 and the roller rolling surface 2a of the nut 2 and moving around the screw shaft while rotating on rotation axes of the rollers. In this roller screw, each of the rotation axes 4a of the rollers 4 substantially crosses a center line 1b of the screw shaft 1. Since each of the rotation axes 4a of the rollers 4 crosses the center line 1b of the screw shaft 1 (in other words, the rollers 4 arranged in the rolling path 3 are not skewed from the beginning) even when the rolling path 3 has the lead, the roller 4 are allowed to move smoothly.

摘要： The present invention provides a roller screw which bears loads in both directions along the axis of the screw shaft and which is also capable of preventing interference between each roller end surface and roller rolling grooves. Between roller rolling surfaces 1a, 1b of the screw shaft 1 and roller rolling surfaces 2a, 2b, respectively, of the nut 2, there are formed two or more roller rolling paths 3a, 3b, respectively. In one roller rolling path 3a, plural rollers 4a are parallel-arranged, and also in another roller rolling path 3b, plural rollers 4b are parallel-arranged. The rollers 4a arranged in the one roller rolling path 3a bear a load in one direction (1) along the axis of the screw shaft 1, while the rollers 4b arranged in the other roller rolling path 3b bear a load in the opposite direction (2) along the axis of the screw shaft 1.

摘要： Provided is a roller screw capable of preventing rollers moving from an unloaded return path to a loaded roller rolling path from coming into collision with a scooping portion. The roller screw has: a screw shaft 1 having a spiral roller rolling surface la formed on an outer peripheral surface thereof; a nut 2 having a loaded roller rolling surface 2a formed in an inner peripheral surface thereof; a circulation member 3 having an unloaded return path connecting one end of the loaded roller rolling surface 2a of the nut 2 to an opposite end thereof; and a plurality of rollers 4 arranged in a loaded roller rolling path 6 and the unloaded return path. In the circulation member 3, as a scooping portion that juts toward the screw shaft 1 and provided for scooping the rollers 4 moving in the loaded roller rolling path 6 up into the unloaded return path, a pair of diagonal corresponding parts 14 is provided which are in contact with diagonal parts 4e of a rectangular side surface of each roller 4 and a width between which is gradually narrower as they are deeper in the unloaded return path in such a manner that a cross section of the unloaded return path is closer to a rectangle.

摘要： The invention relates to a ball screw device in which a screw shaft and a nut member are threadedly engaged with each other through a number of balls. In such a ball screw device, an inner surface of a cover plate contacting an end surface of a nut main body is provided with a projecting return piece adapted to be fit-engaged with a recess cut in an inner peripheral surface of the nut main body, the return piece being provided with a scoop portion for dislodging the balls from the ball rolling groove of the screw shaft and a direction switching passage for guiding the dislodged balls to the entrance of a ball return hole. The projecting return piece is divided into a first piece formed integral with the cover plate and a second piece fixed to the first piece by a curved plane including the center line of the direction switching passage.
