Description

Technical Field

[0001] The utility model belongs to the technical field of tapered roller bearings, in particular to a tapered roller bearing with a lubrication function. Background Art

[0002] Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearings have tapered raceways. This type of bearing is divided into single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction.

[0003] The tapered roller bearing in the prior art mainly comprises a bearing outer ring, a bearing inner ring, a bearing retainer and a tapered roller. When in use, the tapered roller is installed with the bearing retainer and then with the bearing outer ring and the bearing inner ring.

[0004] However, in actual use, there will be great friction between the outer ring of the bearing and the bearing cage, and between the inner ring of the bearing and the bearing cage. Friction will increase the temperature and thus reduce the service life of the bearing. Adding lubricating oil is a common method to reduce friction. However, adding lubricating oil is often done directly. On the one hand, this method requires the bearing to be stationary. On the other hand, direct addition can easily cause the lubricating oil to leak out of the gap, thereby reducing the lubrication function. In addition, the number of additions is relatively frequent, which is very inconvenient. Utility Model Content
