摘要： A roller screw has a screw shaft (1) in the outer peripheral surface of which there is formed a helical roller rolling groove (1a), a nut member (2a) in the inner peripheral surface of which there is formed a helical load roller rolling groove (2a) facing the roller rolling groove (1a), a return pipe (4) inside of which there is formed a roller return path (5) connecting one end and the other end of a load roller rolling path (3) between the roller rolling groove (1a) of the screw shaft (1) and the load roller rolling groove (2a) of the nut member (2), and rollers (6) received in the load roller rolling path (3) and the roller return path (5). The roller return path (5) is twisted so that the rollers change the attitude as they move in the axial direction of the return pipe (4), and this facilitates assembling, makes the structure simple, and enables the rollers to circulate smoothly.
摘要翻译：一种滚柱丝杠，其特征在于，在外周面上形成有螺旋滚柱滚道槽（1a）的螺杆轴（1），在内周面形成有螺旋状的负载滚轴的螺母部件（2a）（3）的一端和另一端之间形成有辊子返回路径（5）的返回管（4），所述辊子返回路径（5）与所述辊子滚动槽（1a）（1）的滚子滚动槽（1a）和螺母构件（2）的负载滚子滚动槽（2a），以及容纳在负载滚子滚动路径（3）中的滚子（6）和滚子返回路径（5）。辊返回路径（5）被扭转，使得辊在返回管（4）的轴向上移动时改变其姿态，并且这便于组装，使得结构简单并且能够使辊平滑地循环。

摘要： There is provided a roller screw comprising a screw shaft 1 having an outer peripheral surface in which a spiral roller rolling groove 1a is formed, a nut member 2 having an inner peripheral surface in which a spiral loaded roller rolling groove 2a is formed so as to oppose to the roller rolling groove of the screw shaft, a return pipe 4 in which a roller return passage 5 is formed so as to connect one and another ends of a loaded roller rolling passage 3 between the roller rolling groove 1a of the screw shaft 1 and the loaded roller rolling groove 2a of the nut member 2, a number of rollers 6 disposed in the loaded roller rolling passage 3 and the roller return passage 5, wherein the roller return passage 5 is twisted so that an attitude of the roller 6 changes as the roller moves in an axial direction of the return pipe 4. Such roller screw enables to provide an easy assembling and compact structure and to realize smooth circulation of the roller.
