New description: [New technical field] This new type is related to the ball recirculating element of the linear actuator, especially the ball reflow element which can reduce the ball turning wear. • [Prior Art] The linear actuator is a power transmission component that is important in the mechanical field. It uses the ball as the contact medium for the two moving parts, so that the two parts are not directly contacted by the entire surface to reduce the components. Frictional resistance caused by moving trees = smoother and less laborious when the mechanism is running. At the same time, due to the reduction of frictional resistance, the wear and temperature between the components are greatly improved, which helps to delay the mechanism and provide the transmission mechanism to operate at a higher moving speed. Ningzhutri's mode of motion can be roughly divided into two types: m-rejected cups and linear ball-shaped slides. The ball screw is made up of a screw groove between the nut and the screw nut to accommodate the ball, and the ball is retracted by the ball returning to the return flow H and the f-foil has a ¥ lead, and the 曰 _ beads It can be cycled between the threads ^ ΓΓ 形成 形成 形成 形成 形成 , , , , , , , , , , , , , , , , 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 Out, where the _ball is turned back to the recirculating rolling groove' and the slider also has the difficulty of sliding the ball in the guide roll so that the ball can slide relative to each other, called the low screw 舆 nut 5 M321958, regardless of the ball For screw or linear ball slides, the balls must be guided through a recirculator to cycle through the thread grooves or rolling grooves, that is, the balls need to be sinners to continue rolling in the thread grooves or rolling grooves. There are many types of reciprocating bears, and most of the reflowers applied to the ball screw are mounted on the ball screw; the cap is inserted into the thread groove and connected to the thread groove to capture the ball from the thread groove. , • or place the ball back into the thread groove; The returning device applied to the linear ball slide is installed at both ends of the slider, and is respectively connected with the rolling groove and the return channel to "connect the ball from the rolling groove" or send the ball back to the roller. In the moving groove, the current general-purpose reflowers are mostly made of plastic injection molding, in order to increase the production capacity and reduce the cost. The returning device has a guiding passage for receiving the ball in and out and guiding the ball turning. However, the ball running When entering or just leaving the returning device, and when the ball is running in the direction of the direction of the guiding channel, it will cause a great impact on the surface of the guiding channel, causing the returning device to wear at these parts. As a result, the thickness of the surface of the guide passage is continuously reduced by wear, so that the ball is more likely to collide due to the excessive clearance when the ball passes, causing the ball to run unsmoothly and generating noise, and the rate of wear is continuously increased, thereby shortening The service life of the plastic and the return flow device can not only achieve the desired work efficiency, but also the maintenance and repair of the south. [New content] In the prior art, the surface of the guide channel of the ball reflow device is easy to be worn by the ball due to the small hardness of the material, resulting in a loss of operation and a sharp decrease in service life. In view of this, the purpose of the present invention is to provide a ball reflow. The component is used to reduce the degree of wear of the ball on the surface of the guide channel. 6 M321958 In order to solve the above problems, the present invention provides a ball reflow element provided in a linear actuator comprising a body and a buffer layer. The transmission device comprises a guide member, a sliding movement along the guiding member, a special movement, wherein at least a movement between the moving member and the guiding member is formed, and the roller is operated, and the ring is operated. The trough. The material surface element has a guiding channel, and the guiding channel comprises a curved section and at least one connecting splicing section is connected to the ball groove to receive the guiding ball in and out of the ball groove. The curved section is used to guide the ball to the reflow. The surface of the buffer body may be a metal layer of the age of the material or a metal sheet bonded to the surface of the guiding channel, thereby increasing the material passage = grinding degree. The buffer layer can also be made of a rib-adsorbing-lubricating material of the lubricating oil, which is used to increase the surface roughness of the guide channel and provide ball lubrication. The disclosed ball circulation element has the effect that the mechanical properties of the guide channel can be enhanced by the buffer layer at the =2=, and the U wear resistance is reduced.

The moving parts chat box is provided with a reflow block 1 and 1_, respectively, which is connected to the ball groove, and each of the 10 M321958 external reflow blocks 100C, K) 〇D is mutually joined to form a guiding channel 1〇4. The outer reflow blocks 100C and 100D respectively have three fixing holes 1〇1, and the receiving groove 15 defines a screw hole 17 corresponding to each fixing hole 101, wherein the screw 19 is screwed through the fixing hole 101. The screw holes 17 are for fixing the outer reflow blocks 100C, 100D to the sliders . The guiding channel comprises a connecting section 105, a curved section 1〇6, a tongue 107 and a conveying section 112. The conveying sections 112 of the external reflow blocks 100C and 100D are connected and connected to each other for mounting a metal tube 113. Set, and inside the metal tube • Form a return channel 18. One end of the connecting section 105 is coupled to the ball groove 14 of the guide member 12 so as to be guided by the guide ball 13 in the ball groove 14 of the guide member 12.
