Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rail slide blocks, in particular to a self-lubricating, long-life, high-lubricity linear guide rail pair. Background Art

[0002] Linear guides are grooves or ridges made of metal or other materials that can bear, fix, guide moving devices or equipment and reduce their friction. They are used in linear reciprocating motion occasions to guide and fix machine parts, special equipment, instruments, etc. They can achieve high-precision linear motion under high load conditions.

[0003] Guide rails are mainly divided into two categories: roller guide rails and ball guide rails. In existing linear guide rails, the rollers and other moving components of the linear guide slider are generally lubricated through the lubricating oil channel at the end cover. Traditional sliding guide lubrication is done by regular manual refueling. When refueling, the lubricating oil is unevenly distributed on the guide rail surface, resulting in the guide rail surface not being effectively and fully lubricated, and the cleanliness of the lubricating oil cannot be guaranteed. The guide rail surface is easily damaged, the accuracy of the guide rail surface cannot be guaranteed, and the maintenance cycle is short. Existing sliders cannot store lubricating oil, and the lubricating oil will gradually be consumed during operation. The lubricating oil needs to be frequently replenished during use, otherwise it is easy to cause the slider and the linear guide to slide unsmoothly, and the wear of the slider and the linear guide will increase, seriously affecting the running accuracy and service life of the linear guide.

[0004] Therefore, how to ensure that the guide rail surface can continue to receive quantitative and evenly distributed lubrication and improve the surface accuracy and service life of the guide rail is an important issue that needs to be solved at present.

[0005] Therefore, we propose a self-lubricating, long-life, high-lubricity linear guide pair to solve the above technical problems. Utility Model Content
