Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a rust-proof bearing ring structure. Background Art

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Double ball bearings are relatively high-end bearings. There are several tiny steel balls in the bearings surrounding the axis. When the fan blades or the axis rotate, the steel balls rotate with them. Because they are all spheres, the friction is small and there is no problem of oil leakage.

[0003] For example, the disclosed utility model provides "a high-load-bearing noiseless bearing", and its announcement number is: CN204082911U. The patent includes an outer ring, an inner ring, and a rolling element; the rolling element is located between the raceways of the inner ring and the outer ring; an axial hole is opened in the inner ring, and a number of oil grooves opening toward the top of the axial hole are evenly opened around the inner wall of the axial hole, and lubricating oil is injected into the several oil grooves around the inner wall of the axial hole. Since the oil grooves are evenly opened on the inner wall of the axial hole, the friction surface between the shaft and the inner wall of the axial hole can be directly reduced, the friction coefficient between the shaft and the axial hole can be reduced, and the noise and current can be reduced.

[0004] The rust-proof bearing ring structure is a component of the bearing, but the previous rust-proof bearing ring structure had some defects in use. For example, it did not have the advantage of good anti-corrosion effect, which caused the rust-proof bearing ring structure to rust easily during use, thereby causing the rust-proof bearing ring structure to be unable to be used normally, and it did not have a strength enhancement structure, which reduced the service life of the rust-proof bearing ring structure and could not meet the needs of the current market. Due to the above problems, the practicality and usability of the rust-proof bearing ring structure were reduced, and a rust-proof bearing ring structure was introduced in a targeted manner.
