Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a machine tool for processing a hub bearing shell. Background Art

[0002] The wheel hub bearing is one of the key parts of the automobile. Its main function is to bear weight and provide precise guidance for the rotation of the wheel hub. This requires it to withstand not only axial loads but also radial loads. It bears both axial loads and radial loads and is a very important part. The wheel hub bearing brings oil between the two surfaces through the relative movement of the shaft and the bearing, forming a sufficient pressure film to separate the two surfaces and thus withstand the load. The wheel hub bearing unit is developed on the basis of standard angular contact ball bearings and tapered roller bearings. It integrates two sets of bearings into one, and has the advantages of good assembly performance, omitting clearance adjustment, light weight, compact structure, large load capacity, grease can be pre-loaded for sealed bearings, omitting external wheel hub seals and maintenance-free. It has been widely used in cars and there is also a trend of gradually expanding its application in trucks.

[0003] Existing machine tools will generate heat when grinding wheel hub bearings, and the more grinding, the more heat will be generated. When the machine tool is allowed to work continuously, the grinding roller will overheat, which will affect the subsequent grinding of the wheel hub bearings. In addition, the wheel hub bearings will produce a lot of metal powder during grinding, and the metal powder will cause harm to the workers. For this reason, we have proposed a machine tool for processing wheel hub bearing shells. Utility Model Content
