Description

Technical Field

[0001] The utility model relates to the technical field of bearing components, in particular to a high-life single-row tapered roller bearing ring. Background Technique

[0002] Tapered roller bearings have the advantages of compact structure, strong load-bearing capacity, separable inner and outer rings, etc. They are widely used in automotive transmissions and are also used in industries such as rolling mills, mines, metallurgy, and plastic machinery. A tapered roller bearing is composed of multiple bearing components, including the bearing ring on its outer side. According to the number of mating rings on the inner side of the bearing ring, it includes a single-row tapered roller bearing ring.

[0003] The following problems still exist when the existing single-row tapered roller bearing ring is in use: Most of them are provided with a mating groove for the bearing inner ring in the middle of the annular inner wall of the single-row tapered roller bearing ring. After the bearing inner ring is assembled and installed, the outer end of the bearing inner ring slides and fits with the inner wall of its mating groove. When the bearing inner ring rotates, it has a large-area sliding friction with the mating groove, resulting in large losses. At the same time, it is inconvenient to add lubricating oil into it through the slot opening of the assembled mating groove. Therefore, the overall durability of the single-row tapered roller bearing ring is not good. Summary of the Utility Model
