Problems solved by technology

[0008] The main technical problem to be solved by the present invention is to provide a new type of linear slide rail holder to overcome the shortcomings of existing linear slide rail holders, such as large friction force, difficult demoulding, and poor oil lubrication. The positioning design with smaller surface and better coverage makes it have the advantages of low friction, easy demoulding, and good oil lubrication

Abstract

A linear slideway retainer is provided, which comprises a plurality of spacers that are arranged at front and rear in proper interval, and two connecting belts that are respectively joined with the left and right ends of the spacers. Wherein, the opposite faces of the spacers from left to right are provided with at least 2 straight restricting faces; the vertical sides of each straight restricting face are respectively a straight face and a grooved face, the adjacent straight restricting faces are arranged in staggered way; the two connecting belts are arranged parallelly, and a plurality of accommodating spaces for the rolling elements are formed between the two connecting belts and the adjacent spacers. The invention employs a positioning design with smaller contact surface and better cladding performance, so that the invention is of low friction and is easy to strip mould, and is of good oil lubrication.

Description

technical field [0001] The invention relates to a linear slide rail holder. Background technique [0002] Generally, the linear slide rail cage is used to maintain the distance between the rolling components in the linear slide rail, so as to avoid collision between the rolling components and prolong the service life, and some types of cages can also contain oil to lubricate the rolling components. Component efficacy. [0003] Please refer to the cage disclosed in U.S. Patent No. 6155718. The cage includes a plurality of disc-shaped spacers between the balls. The spacers are provided with circular recesses corresponding to the balls. Position the ball with a pocket to accommodate one side of the ball. [0004] In order to prevent the balls from falling, the above-mentioned retainer is provided with recesses to position the balls, so as to achieve the effect of spacing the balls and preventing them from falling. However, since the recesses are in contact with the balls on t...
