Description

Technical Field

[0001] This utility model belongs to the technical field of cylindrical roller bearings, specifically a novel cylindrical roller bearing that is resistant to temperature and corrosion. Background Technology

[0002] A cylindrical roller bearing is a radial rolling bearing with cylindrical rollers as the rolling elements. The internal structure of a cylindrical roller bearing uses rollers arranged in parallel, with spacers or spacers between the rollers to prevent tilting or friction between the rollers, effectively preventing an increase in rotational torque.

[0003] Existing cylindrical roller bearings mainly consist of an outer ring, an inner ring, a cage, and cylindrical roller bodies. In use, the cylindrical roller bodies are installed with the cage, and the cage is installed between the outer ring and the inner ring.

[0004] However, in actual use, the height of the bearing will cause the bearing to age and wear more quickly, thus shortening the bearing's service life. The adhesion of external dust and impurities will also cause the outer surface of the bearing to corrode more quickly, thus shortening the bearing's service life. Utility Model Content

Detailed Implementation

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4 As shown, this utility model provides a technical solution: a novel temperature- and corrosion-resistant cylindrical roller bearing, comprising an outer ring 1 and an inner ring 3, with a cage 2 disposed between the outer ring 1 and the inner ring 3. Cylindrical rollers 4 are rotatably mounted on the inner wall of the cage 2. A protective heat dissipation structure 5 is disposed between the outer ring 1 and the inner ring 3. By providing the protective heat dissipation structure 5, the protective ring plate 55 can be auxiliaryly fixed under the action of the annular locking block 53 and the annular locking groove 51. Furthermore, under the action of the threaded retainer 54 and the circular insertion hole 52, and in conjunction with the threaded retainer 56, the protective ring plate 55 can be auxiliaryly fixed, preventing dust and impurities from corroding the outer surface of the bearing. Simultaneously, under the action of the first heat dissipation hole 58 and the second heat dissipation hole 57, the protective ring plate 55 can be further fixed, preventing dust and impurities from corroding the outer surface of the bearing. The heat dissipation effect of the bearing is improved. Protective cleaning structures 6 are provided on both sides of the protective heat dissipation structure 5. By setting the protective cleaning structure 6, the brush ring block 63 and other components can be fixed in place under the action of components such as the annular frame 61 and the annular locking block 62. This can protect and clean the connection between the bearing and the shaft. The protective heat dissipation structure 5 includes annular grooves 51 and two protective ring plates 55. By setting the annular grooves 51 and the protective ring plates 55, the bearing can be protected. There are two annular grooves 51. The two annular grooves 51 are respectively opened on both sides of the inner ring 3 of the bearing. The inner wall of the annular grooves 51 is engaged with annular locking blocks 53. By setting the annular grooves 51 and the annular locking blocks 53, the protective ring plates 55 can be fixed and protected.

[0027] Specifically, such as Figures 2-4As shown, the inner wall of the bearing inner ring 3 is provided with a circular insertion hole 52 on the inner wall of the annular groove 51. A threaded retainer 54 is inserted into the inner wall of the circular insertion hole 52. One side of the outer surface of the threaded retainer 54 is fixedly connected to one of the protective ring plates 55. By setting the threaded retainer 54, it can be used with the threaded retainer 56 for auxiliary fixation. The inner wall of the other protective ring plate 55 is threadedly connected to the threaded retainer 56. The outer surface of the threaded retainer 56 is threadedly connected to the inner wall of the threaded retainer 54. The inner wall of the bearing outer ring 1 is provided with a first heat dissipation hole 58, and the inner wall of the bearing inner ring 3 is provided with a second heat dissipation hole 57. By setting the first heat dissipation hole 58 and the second heat dissipation hole 57, auxiliary heat dissipation can be provided for the bearing outer ring 1 and the bearing inner ring 3.

[0028] Specifically, such as Figure 4 As shown, the protective cleaning structure 6 includes an annular frame 61. One side of the outer surface of the annular frame 61 is fixedly connected to one side of the outer surface of the protective ring plate 55. An annular locking block 62 is engaged with the inner wall of the annular frame 61. By setting the annular locking block 62 and the annular frame 61, the brush ring block 63 can be assisted in disassembly and assembly. The brush ring block 63 is fixedly connected to one side of the outer surface of the annular locking block 62. Several threaded fixing rods 64 are threadedly connected to the inner wall of the annular frame 61. Threaded fixing holes 65 are opened on the inner wall of the annular locking block 62. By setting the threaded fixing rods 64 and the threaded fixing holes 65, the annular frame 61 and the annular locking block 62 can be assisted in fixing. The threaded fixing rods 64 and the threaded fixing holes 65 are detachably threadedly connected.

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

[0030] S1. When in use, the annular locking block 53 is fixed to the annular locking groove 51, thereby making the protective ring plate 55 and the bearing fixed in an auxiliary manner, thus providing auxiliary protection for the bearing. At this time, the threaded locking sleeve 54 is passed through the inner wall of the round insertion hole 52.

[0031] S2. At this time, the threaded clamp 56 and the threaded clamp 54 can be fixed together, thereby fixing the protective ring plate 55 to the bearing. The bearing can also be cooled by the first heat dissipation hole 58 and the second heat dissipation hole 57.

[0032] S3. Insert the annular locking block 62 into the inner wall of the annular frame 61, and then fix the brush ring block 63 to the protective ring plate 55. At this time, the threaded fixing rod 64 and the threaded fixing hole 65 are used for auxiliary fixing, so that the annular locking block 62 and the annular frame 61 are fixed.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
