Abstract
The utility model provides a many lips oil blanket, is equipped with the seal including the skeleton of " L " font on the skeleton, be equipped with the spring in the seal, and seal upper portion is equipped with a primary seal lip, and the lower part of seal is equipped with two secondary seal lips, is equipped with dust lip on the seal of the skeleton bottom of " L " font, and the outside of the seal of the skeleton side of " L " font is equipped with the ripple struction. It is extremely abominable that it can solve the environment that drive axle used when the axle of vehicle that exists among the prior art, when the sand blown by the wind is big, leads to very easily mixing in the oil blanket into dust and sand impurity to lead to the vice lip wearing and tearing of oil blanket, arouse the problem of oil leak. It can block greater part sediment diversion trifle in the world matter, has protected the lip of secondary seal lip and the lip of primary seal lip effectively, is adapted to the use operating mode of bad weather, can make simultaneously the oil blanket better firm with the cooperation of seat hole to the effectual lip of protecting the primary seal lip prevents that dust and sand from getting into the destruction lip and causing the oil leak.
Description
Technical field
This utility model belongs to oil seal technique field, relates to a kind of many lip mouth oil seals.
Background technology
At present, the environment used due to the live axle of the vehicle bridge of some vehicles is extremely severe, and dust storm is big, causes easily being doped in oil sealing sand-dust impurity, thus causes oil sealing pair lip to wear and tear, causes leakage of oil.For this reason, it may be necessary to a kind of many lip mouth oil seals, the environment that the live axle when the vehicle bridge of vehicle in the presence of solution prior art is used is the most severe, when dust storm is big, cause oil sealing is easily doped into sand-dust impurity, thus cause oil sealing pair lip to wear and tear, the problem causing leakage of oil.
Utility model content
This utility model provides a kind of many lip mouth oil seals, the environment that the live axle when the vehicle bridge of vehicle in the presence of solution prior art is used is extremely severe, when dust storm is big, causes easily being doped in oil sealing sand-dust impurity, thus cause oil sealing pair lip to wear and tear, the problem causing leakage of oil.
For achieving the above object, this utility model provides a kind of many lip mouth oil seals, skeleton including " L " font, skeleton is provided with seal, being provided with spring in seal, seal top is provided with a primary seal lip, and the bottom of seal is provided with two secondary sealing lips, seal bottom the skeleton of " L " font is provided with dust excluder lips, and the outside of the seal of the skeleton side of " L " font is provided with ripple struction.
In above scheme preferably, the lip of secondary sealing lip is set to the structure tilted.
It may also be preferred that the incline direction of the lip of secondary sealing lip is towards outside.
It may also be preferred that the lip of dust excluder lips is set to the structure tilted.
It may also be preferred that the incline direction of the lip of dust excluder lips is towards inner side.
It may also be preferred that ripple struction is set to the ripple struction of circular arc.
Compared with prior art, this utility model has the advantage that
Many lip mouth oil seals of the present utility model, can solve the problem that the environment that the live axle when the vehicle bridge of vehicle in the presence of prior art is used is extremely severe, when dust storm is big, cause oil sealing is easily doped into sand-dust impurity, thus cause oil sealing pair lip to wear and tear, the problem causing leakage of oil.It can stop major part sand-dust impurity; it is effectively protected lip and the lip of primary seal lip of secondary sealing lip; it is adapted to boisterous applying working condition; enable to simultaneously oil sealing preferably coordinate with hole, seat firm; thus it is effectively protected the lip of primary seal lip, prevent sand and dust from entering destruction lip and cause leakage of oil.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of many lip mouth oil seals of the present utility model,
Fig. 2 is the structural representation of original oil sealing.
In figure, 1 is skeleton, and 2 is spring, and 3 is primary seal lip, and 4 is secondary sealing lip, and 5 is dust excluder lips, and 6 is ripple struction.
Detailed description of the invention
In order to be more fully understood that this utility model, below in conjunction with specific embodiment, this utility model is explained in detail.It is clear that this utility model can be carried out different modification and remodeling and without departing from this utility model broader spirit and scope of appended claims.Therefore, following example have exemplary and do not have conditional implication.
Embodiment:
A kind of many lip mouth oil seals, skeleton 1 including " L " font, skeleton 1 is provided with seal, spring 2 it is provided with in seal, seal top is provided with a primary seal lip 3, the bottom of seal is provided with two secondary sealing lips 4, and the seal bottom the skeleton 1 of " L " font is provided with dust excluder lips 5, and the outside of the seal of skeleton 1 side of " L " font is provided with ripple struction 6.
In the above-described embodiments, the lip of secondary sealing lip 4 is set to the structure tilted.
In the above-described embodiments, the incline direction of the lip of secondary sealing lip 4 is towards outside.
In the above-described embodiments, the lip of dust excluder lips 5 is set to the structure tilted.
In the above-described embodiments, the incline direction of the lip of dust excluder lips 5 is towards inner side.
In the above-described embodiments, ripple struction 6 is set to the ripple struction 6 of circular arc.
Many lip mouth oil seals of the present utility model, its dust excluder lips 5 can be set to the straight sealing lip on top and the combination of the inclined seal lip of bottom, its spring 2 can be arranged at the inner side of primary seal lip 3, the angle of inclination of the lip of its secondary sealing lip 4 can be to be 45° angle with horizontal direction, the angle of inclination of the lip of its dust excluder lips 5 can be to be 45° angle with horizontal direction, and its ripple struction 6 is set to outer ripple struction.
Many lip mouth oil seals of the present utility model; which increase secondary sealing lip 4 structure, increase the dust excluder lips 5 of a kind of length simultaneously at oil sealing end face, major part sand-dust impurity can be stopped; it is effectively protected secondary sealing lip 4 and the lip of primary seal lip 3, is adapted to boisterous applying working condition.Increase outer ripple struction 6 simultaneously so that oil sealing more preferable coordinate with hole, seat firm.Thus it is effectively protected primary seal lip 3, prevent sand and dust from entering destruction lip and cause leakage of oil.
Although below various preferred implementations of the present utility model and feature being described, but on the premise of without departing from the purpose of this utility model and objective, this utility model can be made many and change, supplements, changes and delete by those of ordinary skill in the art.The detailed description done above in association with specific embodiment of the utility model, is not to restriction of the present utility model.Every according to technical spirit of the present utility model to any simple modification made for any of the above embodiments, all still fall within the scope of technical solutions of the utility model.
