Abstract
The utility model discloses a scavenging collar oil seal which comprises a colloid matter, an external framework and an internal framework, wherein the colloid matter is arranged outside the external framework, the internal framework is arranged in the external framework in an interference way, and one side of the internal framework, which is at the oil level side, is provided with one scavenging hole. The scavenging collar oil seal can stably generate scavenging effect and prevent the oil seal from the unstable working.
Description
Technical field
The utility model relates to automotive oil encapsulation technique field, specifically, relates to a kind of oil return back-up ring oil sealing.
Background technique
Oil sealing is widely used on motor vehicle and the engineering machinery, and it is of a great variety, as be used in the wheel shaft place of wheel wheel limit oil sealing, main subtract oil sealing etc., that oil sealing can play is dustproof, the effect of waterproof, anti-leakage of oil.Especially under the operating mode rugged environment, need the better oil sealing of sealability.Existing oil sealing product all is that the oil return effect that relies on the inside and outside differential seat angle of lip to form realizes sealing.But, therefore cause the instability of oil sealing sealing effect easily because it is many and variable to destroy the factor of oil return effect.
The model utility content
Technical problem to be solved in the utility model provides a kind of oil return back-up ring oil sealing that can stablize formation oil return effect.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: oil return back-up ring oil sealing, comprise colloid, outer skeleton, inner frame, colloid is located at outside the outer skeleton, and described inner frame interference is installed in the outer skeleton, and the side that inner frame is positioned at the pasta side is provided with spill port.
The end that described inner frame is positioned at the pasta side is connected with the colloid part, and this colloid partly has the arc waist.
The terminal fin that is connected with this end that is provided with of described colloid part.
Described oil return back-up ring oil sealing touches mask main lip and the secondary lip that is made of colloid is arranged with being coupling, and main lip inboard is provided with the ring-spring groove, is circular spring and is arranged in the spring groove.
In such scheme, before the oil return back-up ring was placed oil seal lip, when axle rotated, lubricant oil was back in the cavity along the inward turning component that fin produces, before oil seal lip, generate the oil return effect naturally, rely on the oil seal lip and the contact seal realization stable rotation of axle to seal again.The arc waist be used for large eccentricity amount working state next time the oil catch circle initiatively follow off-centre.Spill port is used for sending of lubricant oil that the oil return back-up ring do not stopped.Inner frame, outer skeleton support can be made shape and material change according to the variation of practical set position, and oil sealing can be made shape and material change according to the variation of practical set position.
In sum, the beneficial effects of the utility model are: generation oil return effect that can be stable prevents the instability of oil sealing work.
Below in conjunction with drawings and the embodiments the utility model is described in further detail.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
