摘要： A ball screw with a buffering circulation member comprises: a screw, a nut, a circulation member, a plurality of rolling elements and a plurality of flexible members. The circulation member comprises a first structure and a second structure. The flexible members are disposed at the combining portion between the circulation member and the nut to allow the first and second structures to be assembled more closely in a seamless manner. The flexible members which support the circulation member can absorb or buffer the collision of the rolling elements, thus reducing the vibration of the rolling elements or the noise caused by the collision of the rolling elements.

摘要： Provided is a ball screw module including a screw shaft, a nut member, a ball connector, and a circulating device inside the nut member. The screw shaft and the nut member constitute a first load rolling groove. The circulating device, being connected with the first load rolling groove, has a first turning section and a second turning section, and includes a first guiding groove and a second guiding groove. The first guiding groove has a radius of curvature greater than that of the second guiding groove when the ball connector passes the first turning section. The first guiding groove has the radius of curvature smaller than that of the second guiding groove when the ball connector passes the second turning section.

摘要： An internal circulation ball screw includes a threaded shaft, a nut having a receiving space, a circulation member mounted to the receiving space and having a first circulation groove and a second circulation groove, and a plurality of rolling members running between the threaded shaft and the nut. The first circulation groove defines a first front section, a first rear section, and a first curved section communicating with the first front section and the first rear section separately. The second circulation groove defines a second front section, a second rear section, and a second curved section communicating with the second front section and the second rear section separately. The first and second curved sections define a predetermined included angle with respect to the threaded shaft radially. Therefore, the wall between the circulation channels is uniform to enhance the durability of the ball screw.

摘要： A preload structure for a ball screw in the inner surface of a nut is formed a helical groove whose lead is different from the lead of the adjacent helical groove to produce a lead deviation between the helical groove of the nut and the helical groove of the screw. By such arrangements, the lead deviation can be used to achieve the preload objective, thus reducing the fitting number demanded of the circulation system. Consequently, not only the single circulation system fittings can be used, but also the length of the nut is shorter and without extra machining, and the producer only needs to control the deviation of the interval helical track during rubbing to achieve various preload changes.
摘要翻译：用于螺母内表面的滚珠丝杠的预加载结构形成螺旋槽，该螺旋槽的引线与相邻的螺旋槽的引线不同，以在螺母的螺旋槽与螺杆的螺旋槽之间产生引线偏离。通过这样的布置，可以使用引导偏差来实现预载目标，从而减少循环系统所需的配件数量。因此，不仅可以使用单循环系统配件，而且螺母的长度更短，而且不需要额外的加工，生产者只需要控制摩擦间隔螺旋轨道的偏差，实现各种预载变化。
