AI Technical Summary
Existing seal bearings are prone to problems such as damage and corrosion of seal rings, loss of lubricant and impurities in high temperature and organic solvent environments, resulting in a shorter use time and an increase in maintenance frequency.
A sealing bearing is designed, adopting a two-layer sealing ring structure, wherein the first sealing ring realizes the sealing of lubricating oil through the fixed connection between the mating groove and the clamping groove and the sliding clamping method, and the second sealing ring prevents external impurities from entering through the fixed connection with the outer ring and the inner ring of the bearing and sliding abutment method. Both sealing rings are elastic corrosion-resistant and high-temperature resistant materials.

[0006] Further, the second sealing ring is provided with a protrusion matching the clamping groove, and the second sealing ring is fixedly connected with the outer bearing ring and is in sliding contact with the inner bearing ring. A second skeleton is arranged inside the second sealing ring, and the second sealing ring is used to prevent external impurities from entering the bearing.
[0007] Further, both the first sealing ring and the second sealing ring are elastic, corrosion-resistant and high-temperature-resistant sealing rings, so that the bearing is suitable for high-temperature and corrosion-resistant environments.
[0008] Further, the first skeleton and the second skeleton are hard skeletons, which are used to support the shapes of the first sealing ring and the second sealing ring.
[0009] The utility model further includes other devices or components that can make the sealed bearing work properly, which are all conventional technical means in the art. In addition, the rolling balls and cages not defined in the utility model both adopt conventional technical means in the art.
[0010] The working principle of the present utility model is to achieve the sealing of the bearing by clamping the first connection end into the first mating groove, clamping the second connection end into the second mating groove, and clamping the second sealing ring with the first sealing ring. The outer sides of the first sealing ring and the second sealing ring of the device are made of elastic materials, and are in close contact with the inner ring and the outer ring of the bearing through fixed connection, clamping and abutting, so as to play the role of sealing the bearing.
[0011] The beneficial effect of the present utility model is that when the device is used in high temperature and organic solvents, there will be no phenomenon of damage and corrosion of the sealing ring. The lubricating oil in the sealing ring is separated from the impurities in the environment, and it is convenient to replace the lubricating oil in the bearing, so as to extend the service life of the sealed bearing.
