Abstract
The invention discloses an oil seal of an engine. The oil seal of the engine comprises a pair of frameworks, a pair of supporting bodies and a pair of sealing lips. The frameworks and the supporting bodies are bonded, are firm and have good sealing performance. The frameworks, the supporting bodies and the sealing lips are arranged symmetrically. The sealing lips comprise O-shaped rings. An interval exists between the supporting bodies. Sealing liquid can flow into the space between the O-shaped rings from a cavity formed by the frameworks and supporting ribs. The sealing lips and a fixing shaft are in interference fit. The supporting bodies are provided with elastic ends, and springs are arranged in the elastic ends and prevented from falling off. The follow-up characteristic of the supporting bodies and the sealing lips in the eccentric process is improved, the sealing liquid is prevented from leaking, and the sealing performance of the oil seal is improved.
Description
Technical field
The present invention relates to Manufacturing Technology for Automotive Parts field, be specifically related to a kind of engine oil seal.
Background technique
Rotary shaft lip oil sealing conventional at present is generally made up of support, skeleton, spring, primary seal lip and dust excluder lips, and spring provides radial force for primary seal lip, prevents running shaft operation, the leakage of sealing oil.Dust excluder lips is mainly used in preventing external dust from entering in seal ring, pollutes fluid, damages functional features.But rotate use for a long time along with running shaft, the primary seal lip of the oil sealing be mated and dust excluder lips are easy to just be worn, if and the running shaft bias relative with oil sealing base and beat larger, oil sealing sealing effect will be caused to reduce, further can cause leakage of oil.And the oil sealing constantly more renewed will cause the increase on cost.
Summary of the invention
The object of the invention is to provide a kind of engine oil seal, to solve many defects that prior art deficiency causes.
A kind of engine oil seal, it comprises skeleton, support and sealing lip, described skeleton is the metal ring with L-type cross section, and described support is located between skeleton and oil sealing institute stationary axle, is provided with sealing lip between described support and described axle, described support comprises elastic tip, described elastic tip is built-in with spring, and described skeleton, support and sealing lip have a pair, and are symmetrical arranged, described a pair skeleton top is provided with fixing capping, and is provided with supporting rib between a pair skeleton.
Preferably, O type circle and O type circle baffle ring is arranged with between described pair of seal lips.
Preferably, hole is left between described symmetrically arranged support.
Preferably, described support is connected by bonding mode with skeleton.
Preferably, between described sealing lip and described axle be interference fit.
The invention has the advantages that, this kind of oil sealing, skeleton and support bonding connection, firmly and there is good sealing, described skeleton, support and sealing lip have a pair and are symmetrical arranged, sealing lip also comprises O type circle, hole is left between a pair support, the chamber that sealing fluid can be formed by skeleton and supporting rib flows between O type circle, described sealing lip and institute's stationary axle are interference fit, and support has elastic tip, elastic tip is built-in with spring, prevent coming off of spring, and improve support and the trackability of sealing lip in eccentric process, sealing fluid is prevented to reveal, improve the sealability of oil sealing.
Accompanying drawing explanation
As Fig. 1 be a kind of engine oil seal of the present invention partly cut open structural representation;
Wherein, 1-skeleton, 2-support, 3-sealing lip, 4-supporting rib, 5-axle, 6-elastic tip, 7-spring, 8-fixing capping, 9-O type circle, 10-O type circle baffle ring, 11-hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
As shown in Figure 1, a kind of engine oil seal, it comprises skeleton, support and sealing lip, and described skeleton is the metal ring with L-type cross section, described support is located between skeleton and oil sealing institute stationary axle, be provided with sealing lip between described support and described axle, described support comprises elastic tip, and described elastic tip is built-in with spring, described skeleton, support and sealing lip have a pair, and be symmetrical arranged, described a pair skeleton top is provided with fixing capping, and is provided with supporting rib between a pair skeleton.
It should be noted that and be arranged with O type circle and O type circle baffle ring between described pair of seal lips.
In this example, hole is left between described symmetrically arranged support.
In this example, described support is connected by bonding mode with skeleton.
In addition, between described sealing lip and described axle be interference fit.
Based on above-mentioned, this kind of oil sealing, skeleton and support bonding connection, firmly and there is good sealing, described skeleton, support and sealing lip have a pair and are symmetrical arranged, sealing lip also comprises O type circle, hole is left between a pair support, the chamber that sealing fluid can be formed by skeleton and supporting rib flows between O type circle, described sealing lip and institute's stationary axle are interference fit, and support has elastic tip, elastic tip is built-in with spring, prevent coming off of spring, and improve support and the trackability of sealing lip in eccentric process, sealing fluid is prevented to reveal, improve the sealability of oil sealing.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in right of the present invention the change of the above embodiment, modification.
