Description
Technical field
This utility model relates to sealing ring technical field, is specifically related to the high pressure resistant high temperature of band pore and resistance to water auto pump bearing sealed ring.
Background technology
Auto pump bearing generally adopts the lip-type packing with skeleton, axle is made to produce certain magnitude of interference with contacting of sealing lip during installation, thus producing certain contact to seal thrust, the size of the sealing ring magnitude of interference directly influences sealing property, the magnitude of interference is excessive, excessive frictional heating can be caused, reduce the service life of sealing ring, the magnitude of interference is too small, sealing pressure can be made again too small, causing the leakage of grease, how the selecting properly lip magnitude of interference is the key that auto pump bearing sealed ring designs. From domestic and international research conditions at present, remain in empirically for interference method for determination of amount, theoretical research is comparatively weak, the lip of sealing ring with axle surface contact process in produce along contact width change contact stress, and owing to there is the microcosmic surface unevenness of axle so that axle is when rotating, and the actual microcosmic magnitude of interference of every bit is all constantly changing, the Max.contact stress causing sealing lip and axle surface also constantly changes, thus causing sealing ring fatigue failure. Auto pump bearing is the vitals of cooling water car pumping system, water pump bearing unit operating mode is quite severe, often be in high temperature, run up down, and by axially, impact and the radial centrifugal force of high speed rotating, torsional moment affect, the structural design existing defects of traditional auto pump bearing sealed ring, sealing is not as, and Product Assembly is poor, trap rate is relatively low, and support strength is inadequate, pressure high-temp resistant is not strong, and service life is short.
Summary of the invention
Technical problem to be solved in the utility model is in that to provide the high pressure resistant high temperature of band pore and resistance to water auto pump bearing sealed ring, and it can overcome certain or some defect of prior art.
For solving above-mentioned existing technical problem, this utility model adopts following scheme: the high pressure resistant high temperature of band pore and resistance to water auto pump bearing sealed ring, including body and be arranged on intrinsic skeleton, described body one end is provided with sealing lip, the other end is provided with outer lip, described sealing lip includes the primary seal lip and the second sealing lip that are obliquely installed with body, and described outer lip is connected with body integral type by inclined-plane, and the inclined-plane of described outer lip offers outer pore.
By adopting above-mentioned technological improvement, including body and be arranged on intrinsic skeleton, body one end is provided with sealing lip, the other end is provided with outer lip, sealing lip includes the primary seal lip and the second sealing lip that are obliquely installed with body, outer lip is connected with body integral type by inclined-plane, offers outer pore on the inclined-plane of outer lip, and auto pump bearing solves, by increasing outer pore, the problem that bearing high temperature falls lid.
As preferably, between described primary seal lip and the second sealing lip, angle of inclination is set to 45 degree.
By adopting above-mentioned technological improvement, between primary seal lip and the second sealing lip, angle of inclination is set to 45 degree, has heightened the sealing of sealing ring, and has increased on skeleton both sides here, has improved the support strength of skeleton, it is possible to effectively pre-drop-preventing cover.
As preferably, described skeleton head is fastened in the groove that outer lip indent is formed, and middle part is reversed by flanging and arranged, and afterbody is obliquely installed by oblique foot.
By adopting above-mentioned technological improvement, skeleton head is fastened in the groove that outer lip indent is formed, middle part is reversed by flanging and is arranged, afterbody is obliquely installed by oblique foot, skeleton is made to coordinate with body tacit agreement, realizing the magnitude of interference between sealing lip and mating surface makes sealing member produce elastic deformation to block the gap between relative motion part, thus reaching the purpose sealed.
As preferably, described body adopts elastomeric material integrative-structure to arrange.
As preferably, described skeleton adopts the design of metal material integrative-structure.
By adopting above-mentioned technological improvement, body and skeleton originally Tong Guo elastomeric material and metal material integrative-structure not to arrange, easy to make, Stability Analysis of Structures, resistance to pressure is strong.
Beneficial effect:
This utility model adopts technique scheme to provide the high pressure resistant high temperature of band pore and resistance to water auto pump bearing sealed ring, compensate for deficiency of the prior art, good airproof performance, and trap rate is high, and pressure high-temp resistant resistance to water is strong, long service life.

Detailed description of the invention
For further appreciating that content of the present utility model, in conjunction with the accompanying drawings and embodiments this utility model is described in detail, should be understood that, embodiment be only this utility model made an explanation and and non-limiting, below by specific embodiment, and in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 1, the high pressure resistant high temperature of band pore and resistance to water auto pump bearing sealed ring, including body 1 and the skeleton 2 being arranged in body 1, described body 1 one end is provided with sealing lip 3, the other end is provided with outer lip 4, described sealing lip 3 includes the primary seal lip 31 and the second sealing lip 32 that are obliquely installed with body 1, and described outer lip 4 is connected with body 1 integral type by inclined-plane 41, and the inclined-plane 41 of described outer lip 4 offers outer pore 5. Between described primary seal lip 31 and the second sealing lip 32, angle of inclination is set to 45 degree.
