Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, in particular to a durable self-lubricating linear guide rail group. Background Art

[0002] Guide rail: A device with grooves or ridges made of metal or other materials that can bear, fix, guide moving devices or equipment and reduce their friction. The longitudinal grooves or ridges on the surface of the guide rail are used to guide and fix machine parts, special equipment, instruments, etc. Guide rails are also called slide rails, linear guides, and linear slides. They are used in linear reciprocating motion situations. They have higher rated loads than linear bearings, and can bear a certain torque at the same time. They can achieve high-precision linear motion under high load conditions.

[0003] There is an existing linear guide assembly (application number: 202322779277.6) which scrapes off the oil attached to the slide rail through the oil scraper port on the oil scraper block, and then transports the oil to the oil unloading device through the oil delivery mechanism, and transports the oil to both sides of the slider, thereby removing the scraped oil and improving the service life of the equipment. The above still exists. When the structure is moved linearly, a linear guide is often used. The guide rail can guide the slider, and when the slider moves, a certain friction will be generated between the guide rail, which is not convenient for automatic lubrication, and thus easily leads to more serious wear of the slider and the guide rail, thereby affecting the service life of the linear guide, and the durability is poor. When the slider slides on the outer wall of the guide rail, the friction is large, which is not convenient for reducing the friction between the slider and the guide rail, further affecting the service life of the linear guide.
