Sliding seat rolling system with multi-stage rolling assembly

Abstract

The invention discloses a sliding seat rolling system with a multi-section type rolling assembly. The sliding seat rolling system comprises a rolling element circulation path arranged in a sliding seat, a plurality of rolling elements connected into the rolling element circulation path in a rolling mode and a plurality of retainers; and the retainer comprises tensile bands and spacing pieces, wherein the number of the tensile bands is two, the tensile bands are parallel to each other; the number of the spacing pieces is at least three, the spacing pieces are fixedly connected to the two tensile brands, the two adjacent spacing pieces limit the two ends of the rolling element located in the spacing pieces, each spacing piece is provided with a first contact surface and a second contact surface which are in contact with the rolling element, the first contact surface is provided with a first anti-falling surface, and the second contact surface is provided with a second anti-falling surface. The sliding seat rolling system is simple in structure and long in service life.

Description

technical field [0001] The invention relates to the field of guiding equipment, in particular to a sliding seat rolling system with multi-stage rolling assemblies. Background technique [0002] In the field of guiding equipment, especially the linear motion guiding device, it includes a linear slide rail and a sliding seat moving on the sliding rail; in order to ensure the smooth movement of the sliding seat on the sliding rail, balls need to be installed in the sliding seat, so in The sliding seat is provided with a rolling element load path (load area) and a rolling element return path (non-load area), and the rolling element load path and the rolling element return path are connected by a rolling element transition path set on the end cover to form a rolling element cycle path. The balls move in the circulation path of the rolling elements, and the sliding seat maintains contact with the linear slide rail through the balls, thereby reducing the frictional resistance betw...

AI Technical Summary

Problems solved by technology

[0004] In the use of existing products, there is only one retainer for one rolling element circulation path (the retainer is usually as long as the entire rolling element circulation path), and when the slide seat slides along the slide rail, the rolling element produces a pulling force on the retainer. The strength, coupled with the gravity of the rolling element itself, causes the cage to be stressed at the connection between the load zone and the non-load zone, and the cage is prone to breakage, which affects the service life of the equipment
