Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a long-life tapered bearing. Background Art

[0002] Tapered bearings, commonly referred to as tapered roller bearings, are a common mechanical component consisting of an inner ring, outer ring, rollers, and a cage. Both the inner and outer rings feature tapered raceways, with tapered rollers arranged between them. The projections of all tapered surfaces converge at the same point on the bearing axis. Furthermore, these bearings are separable, meaning the inner ring, rollers, and cage assembly can be installed separately from the outer ring. This feature makes installation and disassembly much easier, facilitating maintenance and component replacement.

[0003] Existing tapered bearings have the following problems during use: they usually have a tapered outer ring on the outside, and a bearing inner ring is concentrically arranged on the inside of the tapered outer ring. Roller slideways are provided on the inside of the tapered outer ring and the outside of the bearing inner ring, and are equipped with a number of rollers. However, after long-term use, the rollers and the roller slideways are severely worn, which seriously affects the relative rotational stability between the tapered outer ring and the bearing inner ring, that is, the service life of the entire tapered bearing is not long.
