The invention discloses a steel ball retainer of a sliding block for a linear guide rail, the steel ball retainer is composed of an outer part and an integrated inner part, the integrated inner part is integrally formed by an original inner part, an upper retaining strip, a middle retaining strip and a lower retaining strip, and dustproof strip fixing grooves can be formed in the matching surfaces of the upper retaining strip and the lower retaining strip in the outer part and the integrated inner part and the guide rail. Nine parts of the steel ball retainer in the prior art are reduced to four parts, so that the efficiency and quality of the whole production and assembly link are effectively improved, the overall use precision of the sliding block is improved, the noise of the steel ball is reduced, and the smoothness is improved.
Description
technical field [0001] The invention relates to the field of guide rails, in particular to a steel ball retainer of a slider used for linear guide rails. Background technique [0002] Linear guides are used in high-precision linear reciprocating motion applications, and can withstand a certain torque, and can achieve high-precision linear motion under high load conditions. [0003] In the current prior art, the linear guide is mainly composed of a track assembly and a slider assembly. The structure is as follows figure 1 and 2 As shown, the track assembly is a single metal track body part, and the slider assembly is mainly composed of a metal slider body, a dustproof sheet, a steel ball, two outer parts (end caps), two inner parts, and an upper holding bar , Two middle holding bars, two lower holding bars, and two outer parts (end caps), two inner parts, one upper holding bar, two middle holding bars, and two lower holding bars belong to steel balls The retaining system, ...
