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.

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。另外，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： An actuator for providing a thrust force over a determined travel, comprising a nut, a screw, a sleeve configured to surround the screw in an axial direction (X-X) of the screw, a plurality of rollers, the nut being configured to cooperate with the screw, the nut being secured to the rollers, which are free to rotate, the rollers being configured to each move in particular in the one of at least one helical guide or the sleeve, the screw being configured in order, when it is turned, to operate the actuator, to rotate the nut when it bears via the rollers on a profile of the helical guide and to thus advance in the axial direction (X-X) of the screw at greater or lesser speed along a slope of the profile of the helical guide. The actuator further comprises a motor configured to turn the screw. Successive values of the slope all along the profile or profiles of respectively the one or more helical guides ae adapted to ensure that the slope systematically compensates for at least one peak of the desired thrust force in order to carry out clipping of the maximum values of the thrust force such that the motor, the screw and the nut are dimensioned to a motor torque value corresponding to the value of the thrust force after clipping.

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 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： There is provided a roller screw in which a twisted amount of an unloaded return path is reduced.The roller screw has a screw shaft 1 having a spiral roller-rolling surface is on an outer peripheral surface thereof; a nut 2 having a spiral loaded roller-rolling surface 2a on an inner peripheral surface thereof, the spiral loaded roller-rolling surface being opposed to the roller-rolling surface is of the screw shaft 1; a circulation member 7 arranged in the nut 2 and formed to have an unloaded return path 8 connecting one end and the other end of the loaded roller-rolling surface 2a, whose turn number is less than one, of the nut 2; and a plurality of rollers 4 arranged in a one-turn roller circulation path composed by a loaded roller-rolling path 6 and the unloaded return path 8. The circulation member 7 guides the rollers which have moved and arrived at the one end of the loaded roller-rolling path 6 having less than one turn, to the unloaded return path 8, and then returns the rollers to the other end of the loaded roller-rolling path 6 having less than one turn. The number of turns of the loaded roller-rolling path 6 is set to be less than one turn, whereby the rollers 4 which have arrived at one end of the loaded roller-rolling path 6 can be transferred to the other end of the loaded roller-rolling path 6 without changing their attitudes.
