Embodiment Construction

[0017] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] as attached figure 1 and attached figure 2 As shown, the present invention provides a spiral groove rotary seal ring for vehicles with a porous end face, 15 spiral grooves 1 and 80 microholes 2 are evenly distributed on the end face of the rotary seal ring along the circumferential direction, and each spiral groove 1 It is extended from the inner circle to the outer circle of the sealing ring, the area formed between adjacent spiral grooves 1 is the platform area, the area formed between the top circle of the spiral groove and the outer circle of the sealing ring is the dam area, and the microholes 2 along the circumference Evenly distributed over the dam area of ​​the seal ring.

[0019] Each microhole 2 is a circular hole with a radius of 0.2 mm, and the aspect ratio of the microhole 2 is 0.008.

[0020] The helix angle θ of the spiral groove ...

Abstract

The invention provides a spiral groove rotary sealing ring with a porous end surface for a vehicle and belongs to the technical field of sealing engineering of automobile transmission devices. 10-20 spiral grooves and 60-90 micropores are uniformly distributed on the end surface of the rotary sealing ring along the circumferential direction, each spiral groove extends from an inner circle of the sealing ring to an outer circle of the sealing ring, and the micropores are uniformly distributed in a barrage area of the sealing ring along the circumferential direction. By means of a structural design of the micropores and the spiral grooves which are formed in the end surface of the rotary sealing ring, the spiral grooves can produce hydrodynamic pressure under high-speed and high-pressure working conditions and achieve non-contacting lubrication, the oil retention function of the micropores under a low-speed working condition guarantees the lubrication of an oil film, thus friction and abrasion of an oil distribution sleeve are reduced, the using performance of the oil distribution sleeve is improved, and the service life of the oil distribution sleeve is prolonged.

Description

technical field [0001] The invention relates to a sealing ring, in particular to a spiral groove rotating sealing ring with a porous end face for vehicles, and belongs to the technical field of sealing engineering of automobile transmission devices. Background technique [0002] In the vehicle transmission system, the rotary sealing ring is used in the oil distribution device of the wet clutch or brake, and is the key sealing element, which directly affects the overall performance, safety, reliability and durability of the transmission. In the actual use process, the failure of the rotary seal often leads to the overall failure of the traditional device. The failure form is mostly severe wear of the sealing end face, and this wear failure depends on the lubrication state of the frictional pair surface. Contents of the invention [0003] In view of this, the present invention provides a spiral groove rotary seal ring for vehicles with a porous end face, which can generate ...
