Abstract
The invention provides a spiral distributed multi-hole end face rotary sealing ring used on a vehicle and belongs to the technical field of sealing engineering of automobile transmission devices. 10-20 spiral areas are evenly distributed on the end face of the rotary sealing ring in the circumferential direction. Each spiral area is formed by extending of an inner circle of the sealing ring towards an outer circle of the sealing ring. Micropores are evenly distributed in each spiral area. Ratio of the superficial area of the micropores to the area of the end face of the sealing ring is 0.15-0.25. According to the spiral distributed multi-hole end face rotary sealing ring used on the vehicle, a structural design that the micropores are formed in the end face of the rotary sealing ring is adopted, the spiral distributed micropores can produce hydrodynamic pressure to achieve non-contact lubrication under the working condition of high speed and high pressure. Meanwhile, the multiple micropores can effectively reduce friction torque, quantity of heat production and frictional wear. An oil film is enabled to be in a lubrication state due to an oil fixing function of the multiple micropores under the low-speed working condition, and then using performance of the sealing ring is improved, and the service life of the sealing ring is prolonged.
Description
Technical field
The present invention relates to a kind of rotating seal ring, be specifically related to a kind of automobile-used rotating seal ring of Spiral distribution formula 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 prior device.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 rotating seal ring of Spiral distribution formula micro-pore face, can pass through the structural design of rotating seal ring surface micro-pores, utilize the hydrodynamic effect and solid oily effect of Spiral distribution formula porous, reduce sealing surface rough peak exposure level, reduce fretting wear, improve its working life.
A kind of automobile-used rotating seal ring of Spiral distribution formula micro-pore face, 10～20 spiral regions on the end face of this rotating seal ring, have been uniformly distributed circumferentially, each spiral region is to be extended to cylindrical by the inner circle of seal ring, each spiral is evenly distributed with micropore on region, and the surface area sum of micropore and the area ratio of seal ring end face are 0.15～0.25.
The helix angle in described spiral region is 15～30 °.
The radial groove platform ratio in described spiral region is 0.6～0.7.
The peripheral groove platform ratio in described spiral region is 0.5～0.6.
Described micropore is circular hole, and radius is 0.15～0.25mm.
The aspect ratio of described micropore is 0.007～0.010.
Beneficial effect:
It is lubricated that the present invention's Spiral distribution formula porous generation hydrodynamic pressure under high speed and high pressure operating mode realizes non-contact, and the existence of porous simultaneously can reduce friction torque and heat yield effectively, reduces fretting wear; Under low speed operating mode, the solid oil effect of porous guarantees film lubrication state, improves seal ring usability and life-span simultaneously.

Embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, describe the present invention.
As shown in Figures 1 and 2, the invention provides a kind of automobile-used rotating seal ring of Spiral distribution formula micro-pore face, on the end face of this rotating seal ring 1, be uniformly distributed circumferentially 15 spiral regions, each spiral region is to be extended to cylindrical by the inner circle of seal ring, each spiral is evenly distributed with micropore 2 in region, the Wei Tai district, region forming between adjacent spiral region.
Each micropore 2 is the circular hole that radius is 0.2mm, and the aspect ratio of micropore 2 is 0.008, and micropore entire area is 0.2 than (the surface area sum of micropore and the area ratio of seal ring end face on seal ring end face).
The helixangleθ in each spiral region is 20 °.

1), in the present embodiment, its radial groove platform ratio is 0.65, peripheral groove platform ratio is 0.55.
As shown in Figure 2, 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 separation; 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.
Under high speed and high pressure operating mode, Spiral distribution formula porous produces hydrodynamic pressure to realize non-contact lubricated, and the existence of porous simultaneously can reduce friction torque and heat yield effectively, reduces fretting wear; Under low speed operating mode, the solid oil effect of porous guarantees film lubrication state, improves seal ring usability and life-span simultaneously.
In sum, these are only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
