Abstract
The utility model discloses a ball heavy-load linear guide rail pair with retaining chains. The guide rail includes a guide rail and slide blocks installed on the guide rail, wherein V-shaped grooves are formed on two side walls of the guide rail, a bulge is formed on the inner side wall of each slide block, ball retaining chains are arranged between the slide rail and the slide blocks, and ball series are arranged in the ball retaining chains. The linear guide rail pair has a simple structure, is easy to realize, greatly improves the loading ability of the guide rail, can bear greater rotating torque and reduces the noise generated by the collision of balls.
Description
Technical field
The utility model relates to the guide rail field, and especially ball class guide rail is specially a kind of with the ball heavy duty linear guide pairs that keeps chain.
Background technique
Guide rail is very wide in the application of mechanical field, is a kind of device that can bear, fix, guide shifter or equipment and reduce its friction.Guide rail is often used for the straight reciprocating motion occasion, has the rated load higher than linear bearing.But traditional spherical guide load is less, and the torque that can bear is little, and can produce bigger noise because ball collides mutually.
The model utility content
The purpose of this utility model provides a kind of with the ball heavy duty linear guide pairs that keeps chain, and little with the spherical guide load that solves conventional art, the torque that can bear is little, the problem that noise is big.
In order to achieve the above object, the technological scheme that the utility model adopted is:
A kind of with the ball heavy duty linear guide pairs that keeps chain, include guide rail and the slide block that is installed on the guide rail, it is characterized in that: described guide rail two side has interior V-shaped groove, the V-shaped groove corresponding position of described slide block madial wall and guide rail forms projection, be provided with ball between the projection of described slide block and the V-shaped groove of guide rail and keep chain, described ball keeps being provided with in the chain ball row that a plurality of ball linear array constitute, and described ball closely contacts with guide rail V-shaped groove inwall, slide block projection.
Described a kind of with the ball heavy duty linear guide pairs that keeps chain, it is characterized in that: described ball keeps chain to be made of the chain of two intersections, and one of them chain is enclosed within outside another chain, and described chain is parallel with guide rail respectively.
The utility model is simple in structure, is easy to realize, the setting by ball keeps chain makes traditional some contact force way into line contact force way, has improved the load capacity of guide rail greatly.The interior V groove of guide rail two side can bear bigger rotational torque simultaneously.Can keep chain to separate by ball between the ball, avoid internal impact, reduce because the noise that the ball collision produces.
