Abstract
The invention relates to an installation-free integrated crankshaft oil seal assembly. Generally, a crankshaft oil seal is needed to be installed inside an oil seal base hole, then an integral oil seal base is assembled to an engine crankshaft, the crankshaft oil seal is needed to be installed on the oil seal base, procedures are complex, unqualified products are produced during the process of installing the oil seal base, and the oil seal leaks oil even falls off due to improper installation or poor matching of the outer diameter of the oil seal and the size of an inner hole of the oil seal base. The installation-free integrated crankshaft oil seal assembly comprises a metal framework (1) which is an integrated framework; rubber (3) is arranged in the center on one side of the metal framework in a projection mode; the framework is provided with two positioning holes (7) and six installation holes (6); a rubber dust proof lip (4) is formed on one protruding side of the metal framework; a rubber sealing lip (5) is formed inside a groove of the metal framework; a spring (2) is installed on the end portion of the rubber sealing lip.
Description
technical field:
the present invention relates to one and exempt to install one-piece crankshaft oil seal assembly.
background technique:
general crank shaft oil seal need to be arranged in oil sealing base hole, more whole oil sealing base is assembled on engine crankshaft.Need be arranged on oil sealing base, operation is many, is arranged on and in the process of oil sealing base, often produces reject.Many times all can because of Rig up error or oil sealing external diameter and oil sealing base endoporus dimensional fits is bad cause oil sealing leakage of oil even to come off.
summary of the invention:
the object of this invention is to provide one and exempt to install one-piece crankshaft oil seal assembly.
above-mentioned object realizes by following technological scheme:
one exempts to install one-piece crankshaft oil seal assembly, its composition comprises: metal frame, described metal frame is integral type skeleton, described metal frame one side central protuberance is suppressed with rubber, on described skeleton, there are two positioning holes and six mounting holes, one side of described metal frame projection is formed with rubber dust-proof lip, and described metal frame groove is formed with rubber seal lip, and described sealing lip end is provided with spring.
beneficial effect:
1. products obtained therefrom of the present invention, without being arranged on oil sealing base, can directly be assembled on engine crankshaft, has saved a procedure, has avoided oil sealing to be arranged in the process of oil sealing base and to produce reject; Of the present inventionly exempt to install its rubber of one-piece crankshaft oil seal assembly and integrated metal skeleton firmly bonds together through over cure, effectively solved and the bad oil sealing leakage of oil causing and the problem coming off have been installed because of oil sealing and oil sealing base.
2. the present invention has adopted the described integrated metal skeleton with positioning hole and mounting hole, and metal frame is to be made by steel plate, can guarantee the intensity of oil sealing.Spring is that stainless steel material is made, and has good stretch-proof and fatigue performance; Rubber is fluorine rubber, has excellent high temperature resistant, resistance to oxidation, oil resistant and chemical proofing.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is side sectional views of accompanying drawing 1.
accompanying drawing 3 is side sectional view part enlarged views of accompanying drawing 1.
in figure: 1 is that metal frame, 2 is that spring, 3 is that rubber, 4 is that dust excluder lips, 5 is that sealing lip, 6 is that mounting hole, 7 is positioning hole.
embodiment:
embodiment 1:
one exempts to install one-piece crankshaft oil seal assembly, its composition comprises: metal frame 1, described metal frame is integral type skeleton, described metal frame one side central protuberance is suppressed with rubber 3, on described skeleton, have two positioning holes 7 and six mounting holes 6, one side of described metal frame projection is formed with rubber dust-proof lip 4, and described metal frame groove is formed with rubber seal lip 5, and described sealing lip end is provided with spring 2.
the present invention, without being arranged on oil sealing base, can directly be assembled on engine crankshaft, has saved a procedure, has avoided oil sealing to be arranged in the process of oil sealing base and to produce reject; Of the present inventionly exempt to install its rubber of one-piece crankshaft oil seal assembly and integrated metal skeleton firmly bonds together through over cure, effectively solved and the bad oil sealing leakage of oil causing and the problem coming off have been installed because of oil sealing and oil sealing base.Adopted the described integrated metal skeleton with positioning hole and mounting hole, metal frame is to be made by steel plate, can guarantee the intensity of oil sealing.Spring is that stainless steel material is made, and has good stretch-proof and fatigue performance; Rubber is fluorine rubber, has excellent high temperature resistant, resistance to oxidation, oil resistant and chemical proofing.
Claims (1)
1. exempt to install one-piece crankshaft oil seal assembly for one kind, its composition comprises: metal frame, it is characterized in that: described metal frame is integral type skeleton, described metal frame one side central protuberance is suppressed with rubber, on described skeleton, have positioning hole and mounting hole, one side of described metal frame projection is formed with rubber dust-proof lip, in described metal frame groove, is formed with rubber seal lip, and described sealing lip end is provided with spring.
