Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, with reference to the accompanying drawing and most
The present invention is described in further detail for good embodiment.
As shown, a kind of cylindrical pair guide rail of the present invention, including lead screw 1, guide rod 2, nut 3, bushing 4, lead screw and nut
It is connected through a screw thread, lead screw is parallel with guide rod, and guide rod passes through nut, and bushing is mounted on outside nut, keeps between bushing and nut
Frame 5, retainer are equipped with multiple balls 6, and ball contacts nut and bushing respectively, and bushing is equipped with interconnecting piece 7.Bushing and nut are logical
Cross ball connection, it is possible to reduce abrasion.Interconnecting piece can connect external structure by modes such as screw threads, transport it with bushing
It is dynamic.
The working principle of above-described embodiment is that lead screw, guide rod and nut may be implemented to move along a straight line, and guide rod limits nut
Rotation, external motivating force drive lead screw rotation, so that it may drive nut for linear motion, bushing and nut can be without restriction
Rotation, therefore a kind of cylindrical pair guide rail may be implemented in the present embodiment.
According to above-described embodiment, it is preferable that further include mounting blocks 8, the both ends of guide rod are respectively fixedly connected with mounting blocks, lead screw
Both ends mounting blocks are connected by bearing.Mounting blocks are for installing guide rail.
According to above-described embodiment, it is preferable that the both ends of nut and bushing are equipped with sealing baffle 9, thrust ring, locating snap ring.Spiral shell
Lubricant grease can be added between female and bushing, sealing baffle can prevent grease leakage.Thrust ring is for preventing retainer from sending out
Raw axial movement.Locating snap ring is for preventing retainer from play occurs.
According to above-described embodiment, it is preferable that sealing baffle is equipped with gasket seal or sealing felt collar.
According to above-described embodiment, it is preferable that retainer is equipped with multiple through-holes, and through-hole is staggered, and steel ball is installed in through-hole.
Present embodiment discloses it is a kind of just with the retainer structure of implementation.
According to above-described embodiment, it is preferable that through-hole is distributed in the perficial helical of retainer.The structure of the present embodiment makes ball
Arrangement it is more uniform, keep the stress of each ball more balanced, reduce the excessive wear of ball.
The beneficial effects of the present invention are: realizing a kind of cylindrical pair guide rail.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
