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 dy

Example Embodiment

[0023] The specific implementation manner of the present invention will be described in further detail below by describing the embodiments with reference to the accompanying drawings.

[0024] The oil storage double lip sealing ring of the present invention, such as figure 1 , 2 , as shown in 4, including the sealing ring body and the sealing lip 1 on one side of the sealing ring body, the sealing lip 1 is provided with two upper and lower arrangement; the side of the sealing ring body with the sealing lip is a dynamic seal The other side is the static sealing side 6, and the oil guide hole 2 communicating with the dynamic sealing side 5 is provided between the static sealing side 6 and the dynamic sealing side 5. In the present invention, an oil storage cavity 4 is formed between the sealing lips 1 , and an oil storage tank 3 is provided on the static sealing side 6 . Both the oil storage chamber 4 and the oil storage tank 3 are annularly arranged along the sealing ring. T...

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...
