摘要： The recirculating element having a turning track corresponding to helical track of a ball screw and corresponding to returning hole of nut. And the turning track comprises a tangential direction changing position and a screw thread departing position being adjacent to an entrance of the turning track. And the entrance of the turning track has an upper wall surface and a lower wall face, which form a first inclined angle and a second inclined angle with the horizontal direction respectively. The first angle of the upper wall surface is smaller or equal to a minimum lead angle of the ball screw and the second inclined angle of the lower wall surface is smaller or equal to a maximum lead angle of the ball screw. So it is suitable for ball screws with different leads.

摘要： A dust-proof structure for a ball screw comprises: a wiper, a wiping piece and a fastening device. The wiper is a C-shaped structure defined with a gap for accommodation of a wiping piece and is annually mounted on a surface of a screw shaft. The wiper is formed at either side of the gap with a bevel surface, and the wiping piece is also formed at both sides thereof with a bevel surface for mating with the bevel surface of the gap, so that the wiper and the wiping piece are maintained into contact via the bevel surfaces. The fastening device enables the C-shaped wiper to be deformed in radial direction, making the wiping piece abut against the surface of the screw shaft. By such arrangements, an interacting force between the bevel surfaces of the wiping piece and the wiper pushes the wiping piece toward the surface of the screw shaft, thus effectively preventing dust.

摘要： A chips dischargeable wiper is disposed at the end of a nut, the wiper is defined with a flange, a plurality of ribs integrally formed with the flange, and a plurality of through holes located beside the flange. The flange is used to mate with the helical groove of the ball screw in such a manner at least a rib tapered from outside in is disposed between the flange and the screw shaft, which not only can reduce the resistance of the wiper, but also can effectively prevent intrusion of foreign objects into the screw shaft and can prevent leakage of lubricating agent. Furthermore, the rib can collect dusts and the foreign objects and discharge them out of the through holes. Therefore, the structure of wiper is simplified and can be used for a long time without maintenance.

摘要： A transmission system with a lubrication device is disclosed. The lubrication device is defined with an accommodation trough and an oil hole. In the accommodation trough is disposed a guiding assembly. The guiding assembly cooperates with the accommodation trough to define an oil storage space for accommodation of lubricating grease. The oil storage space is in communication with the oil hole. A power module is connected to the guiding assembly to drive the guiding assembly at regular intervals to make the lubricating grease overflow to the linear transmission system through the oil hole to perform the lubrication.
