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.

Technical field
The present invention relates to a kind of seal ring, be specifically related to a kind of automobile-used spiral chute rotating seal ring of micro-pore face, belong to the Seal technical field of automotive trannsmission system.
Background technique
In vehicle drive system, rotating seal ring is used for the distributing device of wet clutch or break, is crucial seal element wherein, directly affects overall performance, Security, reliability and the durability of transmission device.Often because the inefficacy of rotary seal, and cause the overall failure of conventional apparatus in the using process of reality.Mostly its failure mode is the heavy wear of seal face, and this wear out failure depends on the lubricating status of friction pair face.
Summary of the invention
In view of this, the invention provides a kind of automobile-used spiral chute rotating seal ring of micro-pore face, can pass through rotating seal ring surface micro-pores and spiral fluted structural design, spiral chute produces hydrodynamic pressure and realizes that non-contact is lubricated under the high speed and high pressure operating mode, under the low speed operating mode, the solid oil effect of micropore guarantees film lubrication, thereby reduce fretting wear, improve its usability and life-span.
A kind of automobile-used spiral chute rotating seal ring of micro-pore face, on the end face of this rotating seal ring, the edge circumferentially is evenly distributed with 10 ~ 20 spiral chutes and 60 ~ 90 micropores, each spiral chute is to be extended to cylindrical by the inner circle of seal ring, and micropore is along circumferentially being evenly distributed on the Ba Qu of seal ring.
Described spiral fluted helix angle is 15 ~ 30 °.
Described spiral fluted radial groove platform ratio is 0.6 ~ 0.7.
Described spiral fluted peripheral groove platform ratio is 0.5 ~ 0.6.
Described spiral fluted groove depth is 10 ~ 15um.
Described micropore is circular hole, and radius is 0.15 ~ 0.25mm, and the aspect ratio of micropore is 0.007 ~ 0.010.
The center of circle of described micropore is 0.8 ~ 0.85 times of seal ring width to the distance of seal ring inner circle.
Beneficial effect:
The present invention utilizes spiral fluted hydrodynamic effect when high speed, during low speed, dynamic pressure effect weakens, but because the existence of surface micro-pores guarantees film lubrication, thereby reduce sealing surface rough peak exposure level, reduce fretting wear, improve its working life.

Embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
As shown in accompanying drawing 1 and accompanying drawing 2, the invention provides a kind of automobile-used spiral chute rotating seal ring of micro-pore face, on the end face of this rotating seal ring, the edge circumferentially is evenly distributed with 15 spiral chutes 1 and 80 micropores 2, each spiral chute 1 is to be extended to cylindrical by the inner circle of seal ring, the zone that forms between adjacent spiral chute 1 is the platform district, the zone that forms between spiral chute groove tip circle and seal ring cylindrical is Ba Qu, and micropore 2 is along circumferentially being evenly distributed on the Ba Qu of seal ring.
Each micropore 2 is the circular hole that radius is 0.2mm, and the aspect ratio of micropore 2 is 0.008.
The helixangleθ of spiral chute 1 is 20 °, and groove depth is 12um.
If the internal-and external diameter of rotating seal ring is respectively r
