Oil storage double-lip sealing ring

Abstract

The invention discloses an oil storage double-lip sealing ring. The oil storage double-lip sealing ring is characterized by comprising a sealing ring body and sealing lips arranged on one side of thesealing ring body, wherein the two sealing lips are arranged up and down; the side, provided with the sealing lips, of the sealing ring body is a dynamic sealing side, and the other side is a static sealing side; and a communicating oil guide hole is formed between the static sealing side and the dynamic sealing side. The oil storage double-lip sealing ring is simple in structure, easy to produceand machine and excellent in sealing and lubricating effects, and achieves higher practicability and better application prospect.

Description

technical field [0001] The invention belongs to the technical field of sealing, and more specifically relates to an oil storage double-lip sealing ring. Background technique [0002] In-wheel motor is a hot research project in recent years. Since it is installed in the wheel hub of the car, the sealing ring between the stator and rotor of the motor can prevent water and impurities from entering the motor. Because there is no oil environment, when the wheel rotates at high speed, the sealing ring between the stator and rotor of the motor will directly contact the sealed surface, and the heat generated by friction will cause the sealing ring to expand, and the contact pressure with the sealed part will further increase, and the friction phenomenon more dramatic. Moreover, the sealing ring is made of soft material, and the relative movement with the sealed surface will cause the surface of the sealing ring to wear, gradually degrade or even lose the sealing ability, which seri...

AI Technical Summary

Problems solved by technology

Moreover, the sealing ring is made of soft material, and the relative movement with the sealed surface will cause the surface of the sealing ring to wear, gradually degrade or even lose the sealing ability, which seriously affects the working reliability of the hub motor

[0003] Dynamic sealing technology has become a key technology for the high reliability research and development of in-wheel motors. In order to reduce the wear degree of the sealing ring under dry friction and dynamic sealing conditions, sometimes the sealing ring material is improved to improve the wear resistance of the sealing ring, or the sealing ring is frequently replaced. However, The improvement of sealing ring materials still needs to be studied, and frequent replacement of sealing rings is not suitable for long-distance vehicles. Therefore, redesigning the structure of sealing rings can effectively improve the wear resistance of sealing rings. has a powerful promoting effect
