摘要： A roller track for a roller screw is formed on a screw and a nut of the roller screw respectively, and the roller track is similar to a V-shaped structure. Round angles with the same radius are formed on the outer edges for contacting rollers. Thereby, the roller chain of the present invention can avoid the two problems of the stress centralization of the rollers and the excessively small contact length of the rollers, further to lift the load capability of the roller screw.

摘要： A sectional circulating assembly for a ball screw comprises an inner circulating block and an outer circulating block. In assembly, the inner circulating block is initially placed between the screw shaft and the nut before the rolling balls and the screw shaft are positioned, thus preventing the rolling balls from dropping out and the interference with the threads. After the rolling balls and the screw shaft are positioned, the outer circulating block is placed into the nut and to be engaged with the inner circulating block, and the outer circulating block is fixed to the nut. This method can maintain the tightness of the nut, thus preventing the leakage of noise.

摘要： A ball screw unit with dust cleaning and ball deflecting element fixing mechanism includes an annular inlaid slot along the inner surface of a nut proper proximate to the outside of a ball deflecting element. A fixed dust scrape formed of a C shaped annular packing is installed in the annular inlaid slot. The C shaped annular packing is covered with a soft covering layer at its inner fringe and the outer fringe of the soft covering layer is just stuffed in the annular inlaid slot of the nut proper. Inner fringe of the soft covering layer is formed into a spiral scraper blade corresponding to the rolling spiral slot of the screw blot. The fixed dust scraper is tightly fixing the ball deflecting element to the nut proper by means of the resiliency of the soft covering layer to clean the dust along the rolling spiral slot with its spiral scraper blade thereby serving as a dust cleaner.

摘要： A dexterously designed rolling element for ball screw unit includes a keg-like body formed of an arcuate line revolved about an axis to form an olive shaped body and then intercepted by two parallel planes perpendicular to the axis. Twice of the radius of the curvature of the body is longer than the width between the adjacent crests of the treaded helical track. The distance between the two parallel planes is shorter than the width between the adjacent crests of the threaded helical track so as to increase the contact surface between the rolling element and the helical track, enforce the load carrying capacity of the ball screw unit, and keep the motion of the rolling element smooth.

摘要： A roller screw system comprises a screw shaft, a nut, a pair of return members, a return pipe and a plurality of rollers. The nut is interiorly defined with a receiving recess for accommodation of the return members, and an abutting surface. The roller screw system is characterized in that a through hole is defined in the nut and is in communication with the return hole. The return pipe is disposed in the through hole of the nut. The return members are disposed in the receiving groove of the nut, forming a return system. And the return system is to be connected to the helical groove of the screw shaft and the nut, thus forming a roller screw system. By such arrangements, the rollers can circulate more smoothly and the size of the nut will not be increased.
