Description

Technical Field

[0001] This utility model belongs to the field of bearing cage technology, specifically a bearing cage with high temperature resistance and long service life. Background Technology

[0002] The cage is one of the main components of a bearing. The cage has four basic functions in rolling bearings: 1. to separate the rolling elements; 2. to hold the rolling elements themselves or to hold them together with a raceway; 3. to guide the rolling elements to roll on the correct track; and 4. to orient the rolling elements and reduce friction. Therefore, the bearing cage plays an important role in the bearing.

[0003] Existing bearing cages mainly consist of a cage body and a roller body. In use, the bearing cage body and the roller body are auxiliaryly fixed together, so that the bearing cage and the bearing can be installed and used normally.

[0004] However, in actual use, the bearing cage generates a lot of heat as it guides the rollers to rotate on the inner and outer rings of the bearing. This causes the temperature of the bearing cage to rise, and long-term use at high temperatures will accelerate the aging of the cage, thus shortening its service life. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To overcome the aforementioned defects in the prior art, this utility model provides a bearing cage with high temperature resistance and long service life. It solves the problem that during actual use, the bearing cage generates a large amount of heat when guiding the rollers to rotate on the inner and outer rings of the bearing, which causes the temperature of the bearing cage to rise. Long-term use at high temperatures will accelerate the aging of the cage and shorten its service life.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a bearing cage with high temperature resistance and long service life, comprising a cage body, wherein the inner wall of the cage body is provided with a high temperature heat dissipation structure, and one side of the outer surface of the cage body is provided with an auxiliary protective structure.

The inner wall of the cage body is provided with an installation groove on one side of the snap-fit ​​groove, and the installation groove is connected to the inner wall of the snap-fit ​​groove. A first rotating rod is rotatably connected to the bottom of the inner wall of the snap-fit ​​groove, and a roller body is fixedly connected to the outer surface of the first rotating rod.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a bearing cage with high temperature resistance and long service life, including a cage body 1. The inner wall of the cage body 1 is provided with a high temperature heat dissipation structure 2. By providing the high temperature heat dissipation structure 2, the cage body 1 can be assisted in heat dissipation. An auxiliary protection structure 3 is provided on one side of the outer surface of the cage body 1. By providing the auxiliary protection structure 3, the first gear 26 and other structures can be assisted in protection. The high temperature heat dissipation structure 2 includes a plurality of snap-fit ​​grooves 21. The plurality of snap-fit ​​grooves 21 are equidistantly circumferentially opened on the inner wall of the cage body 1. An installation groove 22 is opened on one side of the inner wall of the cage body 1 located in the snap-fit ​​grooves 21. By providing the snap-fit ​​grooves 21 and the installation groove 22, the heat inside the cage body 1 can be assisted in heat dissipation. The installation groove 22 is connected to the inner wall of the snap-fit ​​grooves 21. A first rotating rod 24 is rotatably connected to the bottom of the inner wall of the snap-fit ​​grooves 21. A roller body 25 is fixedly connected to the outer surface of the first rotating rod 24. By providing the first rotating rod 24, the roller body 25 can be assisted in rotation.

[0027] Specifically, such as Figures 2-3As shown, the inner wall of the retainer body 1 has a heat dissipation hole 23 on one side of the mounting groove 22. The top of the outer surface of the first rotating rod 24 passes through the retainer body 1 and is fixedly connected to the first gear 26. By setting the first gear 26, it can cooperate with the second gear 28 to perform auxiliary transmission. The bottom of the inner wall of the mounting groove 22 is rotatably connected to the second rotating rod 27. The outer surface of the second rotating rod 27 is fixedly connected to the fan blade body 29. By setting the fan blade body 29, auxiliary heat dissipation can be performed. The top of the outer surface of the second rotating rod 27 is fixedly connected to the second gear 28. The first gear 26 and the second gear 28 are meshed together.

[0028] Specifically, such as Figure 3 and Figure 4 As shown, the auxiliary protective structure 3 includes an annular plate 37. One side of the outer surface of the annular plate 37 is fixedly connected to one side of the outer surface of the retainer body 1. An annular frame 31 is fixedly connected to one side of the outer surface of the annular plate 37. An annular block 34 is engaged with the inner wall of the annular frame 31.

[0029] The working principle of this utility model is as follows:

[0030] S1. When in use, the annular locking block 34 is inserted into the inner wall of the annular locking frame 31. At this time, the threaded locking rod 33 is rotated and inserted into the inner wall of the first screw hole 32 and the second screw hole 36, so that the protective plate 35 can be installed.

[0031] S2. At this time, the roller body 25 drives the first rotating rod 24 to rotate, which in turn drives the first gear 26 to rotate, so that the first gear 26 can drive the second gear 28 to rotate, which in turn drives the second rotating rod 27 to rotate.

[0032] S3. At this time, the second rotating rod 27 can drive the fan blade body 29 to rotate, which can then assist in the heat dissipation inside the mounting slot 22, thereby improving the heat dissipation effect of the cage body 1.
