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
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, 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.In actual using process, often because the inefficacy of rotary seal, and cause the overall failure of conventional apparatus.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, under high speed and high pressure operating mode, spiral chute produces hydrodynamic pressure to realize non-contact lubricated, under 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, 10 ~ 20 spiral chutes and 60 ~ 90 micropores on the end face of this rotating seal ring, have been uniformly distributed circumferentially, each spiral chute is to be extended to cylindrical by the inner circle of seal ring, and micropore is uniformly distributed circumferentially in seal ring Ba district.
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, and 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, 15 spiral chutes 1 and 80 micropores 2 on the end face of this rotating seal ring, have been uniformly distributed circumferentially, each spiral chute 1 is to be extended to cylindrical by the inner circle of seal ring, the Wei Tai district, region forming between adjacent spiral chute 1, the Wei Ba district, region forming between spiral chute groove tip circle and seal ring cylindrical, micropore 2 is uniformly distributed circumferentially in seal ring Ba district.
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.

2, in the present embodiment, the center of circle of micropore 2 is 0.83 times of seal ring width to the distance of seal ring inner ring, the internal-and external diameter that seal ring width is seal ring is poor.
The setting type and the size that adopt above-mentioned spiral chute and micropore, can reduce the fretting wear of rotating seal ring.
As shown in Figure 3, the installment state of the seal ring of the present embodiment under practical application condition, oil-feed cover 6 is for giving system fuel feeding, and oil-feed cover 6 does not rotate for static; Join oil jacket 3 for joining oil to system, join oil jacket 3 and rotate with axle; The periphery of joining oil jacket 3 has rectangle groove, and rotating seal ring 5 is installed in rectangle groove.Before assembling, need first oil-feed cover 6 with to join oil jacket 3 separated; Then rotating seal ring 5 is strutted, be inserted in successively respectively in the rectangle annular groove of joining on oil jacket 3, it should be noted that must be by the porous spiral groove end plane of rotating seal ring 5 towards the abrasive end face of joining oil jacket 3; Finally, the oil jacket 3 of joining that rotating seal ring 5 is housed is packed in oil-feed cover 6, complete the installation of rotating seal ring.
It is lubricated that spiral chute 1 generation hydrodynamic pressure under high speed and high pressure operating mode on rotating seal ring 5 realizes non-contact, and under low speed operating mode, the solid oil effect of micropore 2 guarantees film lubrication, thereby reduces to join the fretting wear of oil jacket 3, improves its usability and life-span.
