[0024] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] Reference Figure 1-4 , which is the first embodiment of the utility model, provides a bearing sealing ring, including a sealing ring body 1, the sealing ring body 1 is set in an annular shape, a plurality of cards 3 are fixedly connected to the inner side of the sealing ring body 1, a groove is opened on the sealing ring body 1, and the interior of the groove includes:

[0027] The reinforcement component 2 includes a metal layer 21, a lower thermal insulation layer 22 is arranged below the metal layer 21, a lower sealing layer 23 is arranged below the lower thermal insulation layer 22, an upper thermal insulation layer 24 is arranged above the metal layer 21, and an upper sealing layer 25 is arranged above the upper thermal insulation layer 24. The metal layer 21, the lower thermal insulation layer 22, the lower sealing layer 23, the upper thermal insulation layer 24 and the upper sealing layer 25 are all annular.

[0028] The upper and lower surfaces of the metal layer 21 are fixedly connected to the upper surface of the lower insulation layer 22 and the lower surface of the upper insulation layer 24 respectively; the upper and lower surfaces of the lower sealing layer 23 are fixedly connected to the lower side of the inner wall of the sealing ring body 1 and the lower surface of the lower insulation layer 22 respectively; the lower surface of the upper sealing layer 25 is fixedly connected to the upper surface of the upper insulation layer 24.

[0029] The surface and inner wall of the metal layer 21, the surface and inner wall of the lower insulation layer 22, the surface and inner wall of the lower sealing layer 23, the surface and inner wall of the upper insulation layer 24 and the surface and inner wall of the upper sealing layer 25 are fixedly connected to the inner and outer sides of the inner wall of the groove respectively.

[0030] The cross sections of the metal layer 21 , the lower heat insulating layer 22 , the lower sealing layer 23 , the upper heat insulating layer 24 and the upper sealing layer 25 are all corrugated.

[0031] During use, the sealing ring body 1 is installed on the bearing. Under the action of multiple cards 3, the sealing ring body 1 is prevented from detaching from the bearing. When the sealing retaining ring is in use, the middle metal layer 21 increases the strength of the sealing retaining ring during use, and avoids large deformation of the reinforcement component 2 during use. At the same time, under the action of the lower insulation layer 22 and the upper insulation layer 24, the thermal insulation performance of the reinforcement component 2 during use is increased. Under the action of the lower sealing layer 23 and the upper sealing layer 25, the sealing performance of the sealing retaining ring is increased.

[0035] The materials of the lower sealing layer 23 and the upper sealing layer 25 are both flexible graphite.

[0036] During use, since the metal layer 21 is 316L stainless steel with high hardness and strength, it can avoid large deformation of the sealing ring during use, thereby increasing the service life of the sealing ring. At the same time, the lower insulation layer 22 and the upper insulation layer 24 are Jinshi high-temperature ceramic fiber paper, which avoids heat transfer and has elasticity. The lower sealing layer 23 and the upper sealing layer 25 are flexible graphite, which increases the overall sealing performance of the sealing ring.
