Seal components, motors

Abstract

The invention provides a sealing assembly and a motor, wherein the sealing assembly includes a plurality of axially stacked sealing ring bodies, the sealing ring bodies include an inner ring body and an outer ring body located on the outer circumferential wall of the inner ring body A ring body, the axial thickness of the inner ring body is smaller than the axial thickness of the outer ring body to form a damping cavity between the two adjacent sealing ring bodies, and the inner ring body is constructed with a penetrating ring body. Orifices at both ends in the axial direction. According to the present invention, on the one hand, the sealing assembly has a damping cavity and a damping hole communicating with the damping cavity, which can utilize the tension property of the fluid to damp the leaked oil layer by layer, thereby improving the sealing effect of the sealing assembly; On the other hand, the number of sealing ring bodies and the number of sealing components can be reasonably selected according to the properties of the lubricating oil and the sealing requirements of the equipment, which improves the sealing performance and effectively improves the design cost and the flexibility of use.

Description

technical field [0001] The invention belongs to the technical field of seal manufacturing, and in particular relates to a seal assembly and a motor. Background technique [0002] Bearings are widely used in rotating machinery such as motors, among which sliding bearings are widely used due to their smooth, reliable and noise-free operation. However, the problem of oil leakage of sliding bearings is also a big problem for users. The leaked oil will infiltrate the stator and rotor of the motor, damage the insulation on the stator and rotor, and affect the service life of the motor. As a result, the lubricating oil in the seat is reduced, which affects the lubrication of the bearing and damages the bearing. SUMMARY OF THE INVENTION [0003] Therefore, the present invention provides a sealing assembly and a motor, which can overcome the deficiencies of oil leakage caused by insufficient sealing at the sliding bearing in the related art, and bearing damage caused by insufficie...
