Embodiment

[0017] Such as figure 1 As shown, a single-row tapered roller bearing has a split structure. The bearing includes an outer ring 1 and an internal component. The outer ring 1 and the internal component are detachably connected, and the internal component includes The inner ring 2, the cage 4 and the tapered roller 3 are connected to the inner ring 2 and the outer ring 1 respectively, and the tapered roller 3 is mounted on the cage 4.

[0018] The inner ring 2, the outer ring 1 and the tapered roller 3 are all made of silico-manganese bearing steel. The inner ring 2, the outer ring 1 and the tapered roller 3 are all treated with high temperature tempering. The cage 4 is a low carbon steel stamped cage.

[0019] The outer dimensions and tolerances of the bearings meet the special requirements of customers for assembly. The bearing can withstand combined axial and radial loads. Bearings can meet the requirements of reliable life and good operation under high temperature environment...

Abstract

The invention relates to a single-row tapered roller bearing. The single-row tapered roller bearing is in a split type structure and comprises an outer ring and internal assemblies, wherein the outer ring is detachably connected with the internal assemblies, the internal assemblies comprise an inner ring, holding frames and tapered rollers, the holding frames are respectively connected with the inner ring and the outer ring, and the tapered rollers are mounted on the holding frames. Compared with the prior art, the single-row tapered roller bearing has the advantages of good performance, wide application rang, high reliability and the like.

Description

Technical field [0001] The invention relates to a bearing, in particular to a single-row tapered roller bearing. Background technique [0002] At present, the bearings used in the steel and metallurgical industries generally use tapered roller bearings, but the bearings cannot withstand high-temperature working conditions, the service life of the bearings is very short, and the working conditions of the bearings are harsh. In response to this situation, a high-temperature-resistant single-row tapered roller bearing can not only withstand the combined axial and radial load, but also can work well under high temperature conditions and have a reliable service life. Special materials are used for the bearing and the bearing is subjected to high temperature heat treatment. , To ensure that the bearing meets the use of harsh working conditions, and the inner, outer diameter and width of the bearing adopt non-standard dimensions and special tolerances. Summary of the invention [0003] ...
