Efficient linear guide rail

Abstract

The invention discloses an efficient linear guide rail. The efficient linear guide rail comprises a steel sliding block, a steel guide rail and ceramic balls, wherein a plurality of sliding block grooves are formed in the steel sliding block at equal intervals; a plurality of guide rail grooves are formed in the steel guide rail at equal intervals; each guide rail groove is symmetrical with the corresponding sliding block groove; one sides of the ceramic balls are in fit contact with the sliding block grooves; and the other sides of the ceramic balls are in fit contact with the guide rail grooves. According to the efficient linear guide rail, the weight of the ceramic balls is 30% of the weight of original steel balls under the condition that the mounting dimension is not changed, the service life of the balls can be prolonged by 100% or above, the linear guide rail achieves the effects of high speed, miniaturization and long service life, and the problems that in the prior art, the change cycle of an all-steel linear guide rail is short due to short service life, the maintenance cost is high, the operation speed is limited, and the all-steel linear guide rail cannot be utilized in high-speed reciprocating occasions are solved.

Description

technical field [0001] The invention relates to a linear guide rail, in particular to an efficient linear guide rail. Background technique [0002] In the prior art, the rails, sliders and spheres of the linear guideway are all made of metal materials. The sliders can be roughly divided into flange type and square type according to the shape and installation method, but the materials are all made of metal. production. The ball is set between the slider and the guide rail, and the guide rail, the slider and the ball are combined to form a relative motion. When they are under load, the contact surface of one of them reaches the wear limit, which means that the entire linear guide has reached the end of its service life. [0003] If the material and hardness of the sphere are equal to that of the guide rail and the slider, since the contact probabilities of the surfaces of the three parts are different, if the slider makes a stroke relative to the guide rail, the surface of th...

AI Technical Summary

Problems solved by technology

Obviously, the damage to the ball is the greatest, and the wear limit is reached at the earliest, so the service life of the ball will be very short, which greatly increases the cost of use

[0004] In addition, if the ball is replaced by a ball with a very high strength and wear resistance coefficient, the guide rail and slider will be easily damaged, so that the linear guide will have a decrease in rigidity, groove scratches, unstable clearance, and broken balls. Crack and other issues
