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 1a 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 present invention relates to a rolling screw whose characteristic is that there are two rows of rollers in the single groove of screw, the rollers in one of the two rows are in a loaded condition and the rollers in the other of the two rows are in an unloaded condition. The return path of the return unit is designed as a U-shaped path that allows the rollers in the same groove to complete a U-shaped turn around. Therefore, the present invention can avoid the uncertain and unsteady movement of the rollers.

摘要： A roller retainer 11 encloses an outer periphery of the roller 9 situated on a diagonal 20 when the roller 9 is viewed from the side surface thereof. Whether the rollers 9 are arranged in a parallel manner or in a cross manner, the roller retainer 11 is able to keep a constant position and thus the disposition of the roller retainer 11 is free from the influence of the direction the roller 9. Also, since the roller retainer 11 restricts a corner portion 9a of the roller 9, the roller 9 is difficult to slip off the roller retainer 11 and thus the roller 9 can be restricted positively, thereby being able to control the skew of the roller 9.
摘要翻译：当从其侧表面观察辊9时，辊保持器11包围位于对角线20上的辊9的外周。无论辊9是平行布置还是以交叉方式布置，辊保持器11能够保持恒定的位置，因此辊保持器11的布置没有辊9的方向的影响。此外，由于辊保持器11限制辊9的角部9a，所以辊9难以从辊保持器11脱落，因此可以积极地限制辊9，从而能够控制辊9的偏斜。

摘要： A roller screw includes a long shaft, a screw nut sleeved onto the long shaft, and rollers, a turnaround member and a turnover member set in between the long shaft and the screw nut. The turnaround member enables the rollers to circulate. The turnover member defines a turnover passage extending over the peripheral surface of the long shaft and connected between two load paths in the long shaft and the screw nut to constitute a circulation path. The direction of arrangement of the rollers before entering the turnover passage is different from that after moving out of the turnover passage so that the amount ratio of the rollers that are arranged in two different directions is kept constant for industrial application.

摘要： A roller screw structure comprises a nut, a screw and a rolling assembly. The rolling assembly is movably disposed between the nut and the screw and includes at least one rolling cone. The slantwise rolling surface of the rolling cone contacts the spiral groove surfaces of the nut and the screw in a line-to-line manner, and the angle between the rolling surface and the self-rotation axis of the rolling cone is from 0 degree to 6.3 degrees. Thereby, making the distance between the self-rotation axis and the rolling surface of the rolling cone of the rolling assembly different can prevent the occurrence of speed difference caused at different rolling paths of the rolling assembly.
