Description

Technical Field

[0001] The utility model belongs to the technical field of bearing sealing rings, and particularly relates to a high-temperature-resistant bearing rubber sealing ring. Background Technique

[0002] A bearing sealing ring is a component installed between the inner and outer rings of a bearing, used to prevent the leakage of lubricating oil or grease, protect the inside of the bearing from the intrusion of dust, moisture and other contaminants. It helps to maintain the lubrication state of the bearing, improve the service life and reliability.

[0003] In the existing bearing sealing rings, when connecting with the bearing, the oil retaining lip of the sealing ring is usually closely attached to the inner ring of the bearing, so as to effectively prevent the lubricating oil or grease from leaking from the inside of the bearing and maintain the lubrication state inside the bearing. However, when the oil retaining lip and the inner ring of the bearing are closely attached, a large friction will be generated between the oil retaining lip and the inner ring of the bearing, which will cause the temperature inside the bearing to rise and affect the service life of the bearing.

[0004] Therefore, we provide a high-temperature-resistant bearing rubber sealing ring to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a high-temperature-resistant bearing rubber sealing ring, which has the advantage of being able to reduce the friction between the inner ring of the bearing and the oil retaining lip by using the lubricating oil on the surface of the bearing, and solves the problem that the internal temperature of the existing bearing rubber sealing ring is easily generated due to friction.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

A first sealing groove is opened in the inner cavity of the first oil seal lip, and a second sealing groove is opened in the inner cavity of the second oil seal lip.

[0008] The utility model is further arranged such that a connecting ring is fixedly connected to the bottom of the support ring, and the bottom of the connecting ring contacts the top of the first oil seal lip.

[0011] The present utility model is further configured such that the number of the first sealing grooves and the second sealing grooves is thirteen each, and the inner cavities of the first sealing grooves and the second sealing grooves are respectively in surface contact with the surfaces of the first oil seal lip and the second oil seal lip.

[0012] The present utility model is further configured such that one side of the connecting ring is provided with an inclined surface, and the bottom of the inclined surface coincides with one side of the top of the first oil seal lip.

[0013] The present utility model is further configured such that one side of the inner cavity of the ring body is provided with an embedded groove, and the bottom of the inner cavity of the embedded groove extends to the top of the support ring.

[0014] The present utility model has the following beneficial effects:

[0023] Next, the technical solutions in the embodiments of the present utility model will be described with reference to the accompanying drawings in the embodiments of the present utility model. The described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Specific Embodiment 1

[0025] Please refer to Figures 1-4 , the present utility model is a high-temperature resistant bearing rubber seal ring, including a ring body 1, and a support ring 2 is fixedly connected to the inner cavity of the ring body 1; a heat-resistant component is arranged at the bottom of the ring body 1, and the heat-resistant component includes a first oil seal lip 3, the first oil seal lip 3 is fixedly connected to one side of the bottom of the ring body 1, a second oil seal lip 4 is fixedly connected to the other side of the bottom of the ring body 1, a first sealing groove 5 is opened in the inner cavity of the first oil seal lip 3, and a second sealing groove 6 is opened in the inner cavity of the second oil seal lip 4.

[0026] Specifically: a clamping groove is opened at the top of one side of the inner cavity of the ring body 1, and through the clamping groove, the rubber seal ring can be installed on the bearing. The support ring 2 can effectively increase the compressive capacity of the seal ring, especially in high-pressure or high-temperature application environments. The first sealing groove 5 and the second sealing groove 6 opened in the inner cavities of the first oil seal lip 3 and the second oil seal lip 4 are both trapezoidal, which can enable the first oil seal lip 3 and the second oil seal lip 4 to be clamped with each other, and can achieve a good sealing effect and reduce the friction force. Specific Embodiment 2

[0028] Please refer to Figures 1-4 , on the basis of Specific Embodiment 1, a connecting ring 7 is fixedly connected to the bottom of the support ring 2, the bottom of the connecting ring 7 is in contact with the top of the first oil seal lip 3, a first oil guiding port 8 is opened on one side of the inner cavity of the connecting ring 7, a first silica gel sponge 9 is fixedly connected to the inner cavity of the first oil guiding port 8, a second oil guiding port 10 is opened on one side of the inner cavity of the first oil seal lip 3, a second silica gel sponge 11 is fixedly connected to the inner cavity of the second oil guiding port 10, the number of the first sealing grooves 5 and the second sealing grooves 6 is thirteen, the inner cavities of the first sealing grooves 5 and the second sealing grooves 6 are respectively attached to the surfaces of the first oil seal lip 3 and the second oil seal lip 4, a slope is opened on one side of the connecting ring 7, the bottom of the slope coincides with one side of the top of the first oil seal lip 3, and an embedding groove is opened on one side of the inner cavity of the ring body 1, and the bottom of the inner cavity of the embedding groove extends to the top of the support ring 2.

[0029] Specifically: The connecting ring 7 connects the bottom of the support ring 2 and the bottom of the first oil seal lip 3, ensuring the sealing performance between the first oil seal lip 3 and the inner ring of the bearing. Moreover, the lubricating oil centrifuged by the rotation of the inner ring of the bearing can be dispersed between the first oil seal lip 3 and the inner ring of the bearing through the first oil guiding port 8, reducing the friction force and improving the high-temperature resistance of the sealing ring. The first silicone sponge 9 and the second silicone sponge 11 have excellent high-temperature resistance and oil resistance, meeting the lubrication requirements in high-temperature environments. The inclined surface enables the connecting ring 7 to form an integral body with the first oil seal lip 3.

[0030] The working principle of the present utility model is as follows: The high-temperature-resistant bearing rubber sealing ring is installed in the installation groove of the bearing. The inner ring of the bearing presses the first oil seal lip 3 at the bottom of the ring body 1, so that the first oil seal lip 3 and the second sealing groove 6 are engaged with each other, and the second oil seal lip 4 and the first sealing groove 5 are engaged with each other, enabling the two oil seal lips to be engaged together, achieving the purpose of reducing the friction force between the sealing ring and the inner ring of the bearing when the bearing rotates.

[0031] Moreover, when the bearing is working, the lubricating oil applied inside the bearing generates centrifugal force due to the rotation of the bearing, guiding a small amount of lubricating oil into the first oil guiding port 8 and the second oil guiding port 10. The first silicone sponge 9 and the second silicone sponge 11 inside the two oil guiding ports seal between the inner ring of the bearing, the first oil seal lip 3 and the connecting ring 7. When the bearing rotates, the lubricating oil adhered to the surface of the silicone sponge lubricates between the bearing, the first oil seal lip 3 and the second oil seal lip 4, avoiding damage to the bearing or the sealing ring caused by high temperature generated by friction.
