Embodiment Construction

[0031] It can be seen from the background art that the oil consumption of the sealing device is large, which is not conducive to saving energy.

[0032] Combine below figure 1 Analyze the reasons for the high oil consumption of the sealing device.

[0033] figure 1 Is a schematic diagram of a sealing device.

[0034] Such as figure 1 As shown, a sealing device includes: a skeleton 5, a dustproof ring 4, a sealing lip is fixed on the skeleton 5, and the sealing lip includes a dustproof lip 3, a main sealing lip 6 and a centrifugal lip 2. In order to ensure good sealing performance, The sealing lip and the dustproof ring 4 are in interference contact, the main sealing lip 6 and the dustproof lip 3 are closely attached to the axial part 42 of the dustproof ring 4, and the centrifugal lip 2 is closely fitted to the radial part 41 of the dustproof ring 4 , During the rotation of the sealing device, the frictional torque between the sealing lip and the dustproof ring is relative...

Abstract

The embodiment of the invention provides a bearing and a sealing device. The sealing device is suitable for being arranged between a first part and a second part which rotate relatively, and comprisesa framework which is integrally of an annular structure and is suitable for being in interference fit with the first part, a main sealing lip which is integrally of an annular structure, is fixed tothe framework and is suitable for being in interference contact with the second part, and a first dustproof sealing lip which is integrally of an annular structure, is fixed to the framework, is provided with a first groove and is suitable for being in interference contact with the second part. According to the bearing and the sealing device provided by the embodiment, the sealing performance of the sealing device can be ensured, and oil consumption can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mechanical seals, in particular to a bearing and a sealing device. Background technique [0002] Cassette seals are generally used to seal wheel bearings of vehicles to protect the rolling elements of the wheel bearings from water, dirt, etc. entering from the outside. [0003] The sealing lip of the box-type sealing device is an interference fit with the dust-proof ring to ensure good sealing performance. However, during the rotation of the sealing device, the oil consumption of the box-type sealing device is large, which is not conducive to energy saving. [0004] Therefore, how to reduce the fuel consumption of the sealing device has become an urgent technical problem to be solved. Contents of the invention [0005] The technical problem solved by the embodiment of the invention is to reduce the oil consumption of the sealing device. [0006] In order to solve the above pr...
