Description

Technical Field

[0001] The utility model relates to the technical field of tapered roller bearings, in particular to a tapered roller bearing retainer. Background Art

[0002] Tapered roller bearings refer to radial thrust rolling bearings whose rolling elements are tapered rollers. When rolling bearings are working, especially when the loads are complex and the bearings rotate at high speeds, the cages must withstand large centrifugal forces, impacts, and vibrations. There is large sliding friction between the cages and the rolling elements, and a large amount of heat is generated. The combined effect of force and heat can lead to cage failure, and in severe cases, it can cause the cage to burn and break. To this end, we propose a tapered roller bearing cage. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a tapered roller bearing retainer that can reduce the sliding friction between the bearing and the rolling elements, reduce the generation of heat, and effectively solve the problems in the background technology.

[0004] To achieve the above-mentioned object, the present utility model provides the following technical solutions: a tapered roller bearing cage, comprising a support bar and a lubrication assembly;

[0005] Support bars: There are fourteen of them. The upper side of all the support bars is equipped with an oil injection assembly, and the lower side of all the support bars is equipped with a storage assembly.

[0006] Lubrication assembly: includes a strip groove, an oil filling pipe and a sponge plate. A strip groove is opened in the middle of the support bar, an oil filling pipe is fixed at the upper end of the strip groove, and a sponge plate is fixed inside the strip groove. The rolling element is lubricated by setting the lubrication assembly.

[0007] Furthermore, the oil filling assembly includes a first support ring and an annular oil filling groove. The first support ring is fixed on the upper side of all the support bars. The upper end of the first support ring is provided with an annular oil filling groove. The lower end of the annular oil filling groove is provided with evenly distributed fixing holes. The upper ends of all the oil filling pipes are respectively fixed inside all the fixing holes. By setting up the oil filling assembly, the lubricating oil is injected into the interior of all the strip grooves.

[0008] Furthermore, it also includes a sealing assembly, which includes a sealing ring and bolts. A sealing ring is provided at the upper end of the annular oil filling groove, and the sealing ring is fixed to the inside of the annular oil filling groove by four bolts. The annular oil filling groove is sealed by providing the sealing assembly.

[0009] Furthermore, the storage assembly includes a second support ring and a collection trough. The second support ring is fixed to the lower side of all the support bars, and the upper end of the second support ring is provided with a collection trough. The excess lubricating oil is stored by setting up the storage assembly.

[0010] Furthermore, evenly distributed fixing grooves are provided on the side surfaces of the support bars, and sponge discs are fixed inside the fixing grooves, so that lubricating oil can be applied to the rolling elements by arranging the sponge discs.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the tapered roller bearing retainer has the following advantages:

[0012] The lubricating oil is stored by setting an annular oil filling groove. After storage, when the rolling body rotates, the lubricating oil inside the annular oil filling groove will enter the interior of all the strip grooves through the evenly distributed oil filling pipes, and then penetrate into the interior of the sponge board. The lubricating oil penetrated into the interior of the sponge board will penetrate into the interior of all the sponge plates. In this case, the lubricating oil can be applied to the surface of the rolling body, which can effectively reduce the friction between the support bar and the rolling body, thereby reducing the heat generation, and thus improving the service life.

[0019] Support bars 1: There are fourteen of them. An oil filling assembly 3 is installed on the upper side of all support bars 1, and a storage assembly 5 is installed on the lower side of all support bars 1. The oil filling assembly 3 includes a first support ring 31 and an annular oil filling groove 32. The upper side of all support bars 1 is fixed with a first support ring 31. The upper end of the first support ring 31 is provided with an annular oil filling groove 32. The lower end of the annular oil filling groove 32 is provided with evenly distributed fixing holes. The upper ends of all oil filling pipes 22 are respectively fixed inside all the fixing holes. It also includes a sealing assembly 4, which includes a sealing ring 41 and bolts 42, a sealing ring 41 is provided at the upper end of the annular oil filling groove 32, and the sealing ring 41 is fixed to the inside of the annular oil filling groove 32 by four bolts 42. The storage assembly 5 includes a second support ring 51 and a collection groove 52. The lower side of all support bars 1 is fixed with a second support ring 51, and the upper end of the second support ring 51 is provided with a collection groove 52. The excess lubricating oil is stored by providing the storage assembly 5, the annular oil filling groove 32 is sealed by providing the sealing assembly 4, and the lubricating oil is injected into the interior of all strip grooves 21 by providing the oil injection assembly 3;

[0020] Lubrication component 2: includes a strip groove 21, an oil filling pipe 22 and a sponge plate 23. A strip groove 21 is opened in the middle of the support bar 1, an oil filling pipe 22 is fixed at the upper end of the strip groove 21, and a sponge plate 23 is fixed inside the strip groove 21.

[0022] The working principle of a tapered roller bearing retainer provided by the utility model is as follows: first, remove all the bolts 42, and then remove the sealing ring 41. After the sealing ring 41 is removed, inject the lubricating oil into the inside of the annular oil filling groove 32. After the injection is completed, use the bolts 42 again to fix the sealing ring 41. After fixation, during the rotation of the rolling body, the lubricating oil inside the annular oil filling groove 32 will enter the inside of all the strip grooves 21 through the evenly distributed oil filling pipes 22, and then penetrate into the inside of the sponge plate 23. The lubricating oil immersed in the inside of the sponge plate 23 will penetrate into the inside of all the sponge plates 6.
