Return flow system of linear slide rail

Abstract

The invention relates to a linear sliding rail return flow system, formed with upper and lower return circuit space between sliding rails, slide blocks jacketed on the sliding rails, and the two sides of each one in two groups of sliding block end covers, respectively, for multiple rolling bodies to make limitless rolling circulation, where one side of the end cover is equipped with upper turning channel and lower turning channel and the other side is equipped with inclined turning channel and U-shaped turning channel, which forms a return flow system integrating cross return flow turning path with split return flow turning path. Thus, the rolling bodies arranged in the return flow spaces only need two installation operations, able to raise production assembly efficiency. Besides, when the rolling bodies in the upper and lower rows make return flow movement, it can make them perform exchange circulation and smoothly turn and make their received force and oil path lubrication uniform, and can increase number of circulating rolling bodies and effectively improve linear sliding rail reliability.

Description

technical field [0001] The invention relates to a return system of a linear slide rail, in particular to the return space formed by the pointer for the slide rail, the slide block that fits on the slide rail, and the end caps of the two jointed oil scrapers for the rolling circulation of many rolling elements. A recirculation structure that combines a crossed recirculation path and a split recirculation path as one. Background technique [0002] The linear slide rail is a rolling guide mechanism. Its structure includes: slide rail, a slider that fits the slide rail, an end cover connecting the two ends of the slider, an oil scraper that fits the end cover, and a slide rail, Most of the rolling elements between the slider and the end cover mainly perform an infinite rolling cycle in the turning between the slider and the slide rail and the end cover through most of the rolling elements, so that the load platform can easily move along the slide rail through the slider.

AI Technical Summary

Problems solved by technology

[0004] 1. It is inconvenient to install the rolling elements: the above-mentioned linear slide rails have four independent return systems, and four bead loading actions are required during production

[0005] 2. Uneven lubrication of the rolling elements: It is difficult to evenly lubricate the four independent return systems at the same time with the above-mentioned linear slide rail technology. Due to gravity, the lower row of rolling elements usually leaves more lubricating grease, causing the upper, Uneven amount of oil in the lower two rows

[0006] 3. Uneven stress on the rolling elements: When the above-mentioned linear slide rail is subjected to a positive load, it will seriously cause uneven stress on the upper and lower rows of rolling elements
