Abstract
The utility model is to provide an engine oil seal with simple structure, for simplifying the assembly procedures and improving the assembly precision. The engine oil seal includes a shell and a rubber seal sulfurized with the shell; the shell is provided with an installation hole; the rubber seal includes an axial seal, a side seal and an end face seal; the axial seal, the side seal and the end face seal are integrated with the shell. The utility model has advantages of convenient installation, good tightness, wide application scope of temperature from -20 to 230 Celsius system and highest linear speed up to 25m/s, and is widely applicable in the sealing field of automobile engines.
Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to the seal arrangement that a kind of running shaft of motor is used.
Background technique
Engine revolution shafting oil envelope of the prior art all is the monomer Sealing that adopts, the Sealing interference that needs will to be used for one by one to seal sagittal plane, side and end face when mounted is assembled on the pedestal, this pedestal refills on the relevant position that is fitted on motor then, so not only assembly process is more loaded down with trivial details, increase workman's burden, but also had the low problem of secondary assembly precision.
Summary of the invention
The utility model aims to provide a kind of engine oil simple in structure, that reduce assembly process, raising assembly precision and seals.
The technical solution of the utility model is achieved in that it comprises housing and is the rubbery sealed body of one with the housing sulfuration, is provided with mounting hole on the housing.Described rubbery sealed body comprises that the diameter of axle is to seal, side seal body and end face seal body.The diameter of axle is provided with primary seal lip and secondary sealing lip on seal, and the spring groove that is used for fastening primary seal lip, and fastening spring is set in the spring groove.Side seal body and end face seal body and housing are structure as a whole, and are positioned at the corresponding depression of housing.Mounting hole comprises positioning hole and pilot hole, and pilot hole comprises smooth circular hole and tapped hole, and wherein smooth circular hole is distributed in the periphery of side seal body, and tapped hole is symmetricly set on the both sides of end face seal body.Housing is a lightweight material.Housing can adopt aluminium to make.Housing also can adopt plastics to make.Described rubber body is the fluorine rubber body.

Embodiment
As shown in Figure 1, the utility model comprises aluminium casing 5 and is that with housing 5 sulfurations the fluorine rubber seal of one, rubbery sealed body comprise that the diameter of axle is to seal 2, side seal body 3 and end face seal body 4; The diameter of axle is provided with primary seal lip and secondary sealing lip on seal 2, and the spring groove that is used for fastening primary seal lip, and fastening spring 6 is set in the spring groove; Side seal body 3 and end face seal body 4 are structure as a whole with housing 5, and are positioned at housing 5 corresponding depressions.Positioning hole 1 and pilot hole are set on the housing 5, and pilot hole comprises smooth circular hole 7 and tapped hole 8, and wherein smooth circular hole 7 is distributed in the periphery of end face seal body 3, and tapped hole 8 is symmetricly set on the both sides of side seal body 4.Rubbery sealed body of the present utility model and housing 5 sulfurations are structure as a whole, and have reduced assembly process, have avoided the low problem of secondary assembly precision, have avoided assembling the improper oil sealing leakage of oil that causes.Unitized seal of the present utility model is provided with positioning hole 1 and pilot hole at the periphery of housing 5, can directly unitized seal of the present utility model be fixed to the corresponding site of motor like this.The seal of oil sealing comprises three seals, be respectively that the diameter of axle is to seal 2, side seal body 3, end face seal body 4, like this as long as this motor body unitized seal can be with the thorough seal that realizes this position diameter of axle face of motor, side and three faces of end face.
As shown in Figure 1, around housing 5, be provided with positioning hole 1 and pilot hole, it can be fixed on the motor by positioning hole and pilot hole, three of oil sealing sealing surface side seal bodies 3, end face seal body 4 and the diameters of axle all just in time snap into corresponding position to seal 2 like this, the diameter of axle shown in Figure 3 to two sealing lips of seal 2 directly and being coupling of motor touch, place on the spring groove at the back side and tighten spring 6, make the diameter of axle of oil sealing very tight with combining of axle to seal 2; End face seal body 4 and side seal body 3 also are fixed on its corresponding end face.As shown in Figure 4, the side seal body 3 of oil sealing has a sealing lip, is that line contacts with the side, can keep good sealing property.As shown in Figure 5, the end face seal body 4 of oil sealing also has a sealing lip, and it also is that a line contacts with end face, also can keep good sealing property with end face.
The utility model simple installation, good airproof performance, the Applicable temperature scope can reach more greatly-scope of 20-230 degree centigrade, its maximum linear velocity can reach 25 meter per seconds.The field of sealing technology that can be widely used in motor car engine.
