Technical Field
[0001] This utility model relates to the field of bearing technology, specifically a high-temperature resistant bearing. Background Technology
[0002] Bearings are essential components in modern machinery. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Currently, most high-temperature bearings on the market consist of a cavity filled with high-temperature grease between the outer ring and the steel balls, with a dust cover or sealing ring between the inner and outer rings. This high-temperature grease protection structure is relatively complex. Furthermore, the high cost of high-temperature grease leads to higher bearing manufacturing costs; additionally, high-temperature grease has low heat absorption efficiency and, once melted, is liquid and prone to leakage.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature resistant bearing, comprising:
[0005] The inner ring has multiple rollers at the middle position of its outer surface and dust-proof rings on both sides of its outer surface.

During the rotation of the bearing, the heat generated by the friction between the roller and the inner and outer rings is guided to the outside by the heat-conducting structure. During the rotation of the outer ring, the heat-conducting structure is driven to rotate, and the grooves on the heat-conducting structure can rotate accordingly, driving the air to form an airflow to dissipate heat on one side of the heat-conducting structure. The heat dissipation grooves on the outer ring also rotate accordingly, driving the air to form an airflow to dissipate heat on the other side of the heat-conducting structure, thereby avoiding the leakage of lubricant due to excessive melting.
[0009] Preferably, a moving groove is provided at the middle position of the outer surface of the inner ring and at the middle position of the inner surface of the outer ring. The size of the moving groove on the inner and outer rings is adapted to the size of the roller, and the roller moves within the sealed space through the moving groove.

[0012] By adopting the above technical solution, the dustproof ring is stably and securely installed between the inner and outer rings through the retaining ring and the retaining groove. The dustproof ring is slidably connected to the inner and outer rings, which can prevent the inner and outer rings from moving due to rotation. Furthermore, the fit between the retaining ring and the retaining groove can prevent lubricant leakage.
[0013] Preferably, a retainer is provided on both sides of the roller, the roller is engaged with the retainer, and the sealed space formed by the inner ring, outer ring and dust ring is filled with lubricant.
[0014] By adopting the above technical solution, there are multiple rollers, and the cage can limit the distance between each pair of rollers, so as to avoid damage to the rollers due to collision during the movement of multiple rollers in the sealed space.
[0015] Preferably, a contact element is provided on the inner side of the heat-conducting structure, and the heat-conducting structure comes into contact with the lubricant in the sealed space through the contact element.
[0016] By adopting the above technical solution, during the rotation of the bearing, the heat generated by the friction of the inner ring, rollers and outer ring due to rotation can be conducted to the contact parts through the lubricant, and then the heat-conducting structure can conduct the heat to the outside.
[0017] Preferably, sealing grooves are provided on both sides of the outer surface of the inner ring and both sides of the inner surface of the outer ring, and sealing rings are provided on the inner ring and the outer ring through the sealing grooves.

[0019] Preferably, the dustproof ring is in contact with the sealing ring, and the outer ring has a fixing groove inside, and the outer ring is connected to the heat-conducting structure through the fixing groove.
[0020] By adopting the above technical solution, the cooperation between the dustproof ring and the sealing ring can prevent external dust and moisture from entering the bearing through the connection between the retaining ring and the retaining groove, thus preventing the lubricant inside the bearing from emulsifying.
[0021] Preferably, the thermally conductive structure is composed of a thermally conductive material.
[0022] By adopting the above technical solution, the thermally conductive material has good thermal conductivity and can conduct the heat in the lubricant to the outside.
[0023] Compared with the prior art, the beneficial effects of this utility model are as follows: The high-temperature bearing has a heat-conducting structure on its outer ring. During the rotation of the bearing, heat is transferred to the outside through the heat-conducting structure on the outer ring, thus achieving a heat dissipation effect. Furthermore, grooves are evenly spaced on the heat-conducting structure. During the rotation of the heat-conducting structure, the grooves drive air to generate airflow on one side of the heat-conducting structure, improving the heat dissipation effect. In addition, heat dissipation grooves are provided on the outer ring, generating airflow on the other side of the heat-conducting structure, further improving the heat dissipation effect.

During the rotation of the bearing, the heat generated by the friction between the roller 2 and the inner ring 1 and the outer ring 3 is guided to the outside by the heat-conducting structure 4. During the rotation of the outer ring 3, the heat-conducting structure 4 is driven to rotate, and the groove 5 on the heat-conducting structure 4 can rotate accordingly, driving the air to form an airflow to dissipate heat on one side of the heat-conducting structure 4.

The size of the moving groove on the inner ring 1 and the outer ring 3 is adapted to the size of the roller 2. The roller 2 moves in the sealed space through the moving groove.

The dustproof ring 9 is stably and firmly installed between the inner ring 1 and the outer ring 3 through the retaining ring and the retaining groove. The dustproof ring 9 is slidably connected with the inner ring 1 and the outer ring 3, which can prevent the inner ring 1 and the outer ring 3 from moving due to rotation. The fit between the retaining ring and the retaining groove can prevent the lubricant 8 from leaking.
[0033] In this embodiment, a cage 10 is provided on both sides of the roller 2. The roller 2 is engaged with the cage 10. The sealed space formed by the inner ring 1, the outer ring 3 and the dust ring 9 is filled with lubricant 8.

The bearing can also be without lubricant 8, and heat can also be conducted to the heat conduction structure 4 through the outer ring 3.
[0034] In this embodiment, a contact element is provided on the inner side of the heat-conducting structure 4.

The outer ring 3 is connected to the heat conduction structure 4 through the fixing groove. Through the cooperation between the dust baffle ring 9 and the sealing ring 6, external dust and moisture can be prevented from entering the bearing from the connection between the retaining ring and the retaining groove, thus preventing the lubricant 8 inside the bearing from emulsifying.
[0037] In this embodiment, the heat-conducting structure 4 is composed of a heat-conducting material, which has good thermal conductivity and can conduct heat from the lubricant 8 to the outside.
[0038] Working principle: When the user installs the bearing, the heat-conducting structure 4 extends from the connection of the device to the outside. During the rotation of the bearing, the heat generated by the friction between the roller 2 and the inner ring 1 and the outer ring 3 is guided to the outside by the heat-conducting structure 4. During the rotation of the outer ring 3, the heat-conducting structure 4 is driven to rotate, and the groove 5 on the heat-conducting structure 4 can rotate accordingly, driving the air to form an airflow to dissipate heat on one side of the heat-conducting structure 4.
