Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a novel double outer ring split tapered roller bearing. 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 different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. It is mainly used to withstand combined radial and axial loads, with radial loads being the main load.

[0003] During long-term use, after repeated lubrication, double-row tapered roller bearings tend to accumulate a large amount of oil-dirt mixture in the middle of their outer rings (specifically between two adjacent double-row tapered roller bearings), which seriously affects the bearing's transmission efficiency. However, due to the relatively complex disassembly process of traditional double-row tapered roller bearings, it is particularly difficult to effectively clean this oil-dirt mixture. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] Therefore, the purpose of the present utility model is to provide a new double outer ring split tapered roller bearing, which is designed to solve the problem that "in the long-term use process, after the double row tapered roller bearing is lubricated multiple times, a large amount of oil and dirt mixture is easily accumulated in the middle part of the outer ring (especially between two adjacent double row tapered roller bearings), which has a serious impact on the transmission efficiency of the bearing.
