AI Technical Summary
When the tapered roller bearing is under heavy axial force, the side of the roller slides and friction with the inner ring retaining edge during operation, and the oil film is thinner, resulting in a large heat generation.
Wavy grooves are processed on the edges of the inner ring of the bearing to store grease, forming a thicker oil film to reduce friction.
By forming a thicker oil film, the friction between the roller side and the inner ring barrier of the bearing is reduced, thereby reducing heat generation.

Abstract
Description
Technical Field
[0001] The utility model relates to a structure for reducing heat generation of a tapered roller bearing, which is used in the tapered roller bearing to achieve the purpose of reducing the heat generation when the tapered roller bearing works. Background Art
[0002] At present, when the used tapered roller bearing works, due to the large axial force it bears and the sliding friction between the side of the roller and the inner ring rib, although there is an oil film, because the oil film is relatively thin, the heat generation of the tapered roller bearing is relatively large. Summary of the Invention
[0003] In order to achieve the purpose of reducing heat generation when the tapered roller bearing works, the utility model provides a structure for reducing heat generation of a tapered roller bearing.
[0004] The solution adopted by the utility model to solve its technical problems is: a wavy groove is machined by electric spark on the rib of the bearing inner ring 4, and the lubricating grease 5 can be stored in the groove. When the side of the roller 3 slides on the rib of the bearing inner ring 4, the lubricating grease stored in the groove can form a relatively thick oil film between the two, reducing the friction between the side of the roller 3 and the rib of the bearing inner ring 4, so as to achieve the purpose of reducing heat generation when the tapered roller bearing works.
[0005] The beneficial effect of the utility model is: the invention can reduce the heat generation caused by the friction between the side of the roller 3 and the rib of the bearing inner ring 4 due to the insufficient thickness of the oil film when the tapered roller bearing works.

[0010] In the figure, 1. bearing outer ring, 2. cage, 3. roller, 4. bearing inner ring, 5. lubricating grease. Detailed Description of the Invention
[0011] In Figure 1 、 Figure 2In it, a circle of wavy grooves is machined by electric discharge machining on the retaining edge of the inner ring 4 of the bearing. Grease 5 can be stored in the grooves. When the side surface of the roller 3 slides on the retaining edge of the inner ring 4 of the bearing, the grease stored in the grooves can form a relatively thick oil film between the two, reducing the frictional force between the side surface of the roller 3 and the retaining edge of the inner ring 4 of the bearing, thereby achieving the purpose of reducing the heat generation during the operation of the tapered roller bearing. The beneficial effect of the utility model is that the present invention can reduce the heat generation caused by the friction between the side surface of the roller 3 and the retaining edge of the inner ring 4 of the bearing due to the insufficient thickness of the oil film during the operation of the tapered roller bearing.
