Abstract

The invention relates to the technical field of high-end equipment. The roller is used for a rolling bearing, serves as a rolling part, and is characterized by comprising the roller shell structure described in the claim 1, a porous element (2) and a fluid driving structure; a main cavity (1-1) is formed in the roller shell structure, the two ends of the roller shell structure are each provided with a hole, and the main cavity (1-1) is communicated with the outside through the two holes. The porous element (2) is positioned in a main cavity (1-1) of the roller shell structure and is provided with a liquid flow through hole (2-1); the fluid driving structure is located in the liquid flow through hole (2-1), and the fluid driving structure drives lubricating oil in the environment where the roller is located to flow through the liquid flow through hole (2-1) and rotate. The high-end bearing is provided with the pin roller, and the pin roller is the pin roller. The high-end equipment is provided with the bearing, and the bearing is the high-end bearing. The device is easy to maintain, low in cost, long in precision service life, ingenious in design and high in adaptability, and the scrap containing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of high-end equipment, in particular to rollers, high-end bearings and high-end equipment. Background technique [0002] High-end equipment refers to high-precision or high-load or high-difficulty equipment. High-end equipment is the industrial foundation. In countries without high-end equipment industry, the development of science and technology industry and economy is difficult. [0003] Most high-end equipment has high-end bearings. High-end bearings include high-precision bearings, high-load bearings, high-corrosion-resistant bearings and other types. High-end bearings are expensive and expensive, and high-precision bearings are required in high-precision situations. [0004] High-precision bearings require extremely high accuracy, and it is difficult to maintain after the accuracy is reduced. Most of the high-precision bearings need to be replaced directly after the accuracy is reduced, which is a ver...
