Abstract
The utility model discloses a kind of oil sealing, comprise support, skeleton, sealing lip, wherein skeleton is enclosed in support, and described sealing lip comprises a primary seal lip and a secondary sealing lip; Or sealing lip comprises a primary seal lip and a dust excluder lips, outwards tiltedly outstanding bottom described dust excluder lips relative support body.Adopt oil sealing described in the utility model, the wearing and tearing of sealing lip can be reduced, extend the working life of oil sealing, its sealability can be improved further simultaneously.
Description
Technical field
The utility model relates to a kind of Sealing, is specifically related to a kind of oil sealing.
Background technique
Rotary shaft lip oil sealing conventional at present is generally made up of support 1, skeleton 2, spring 3, primary seal lip 5 and dust excluder lips 6, and spring 3 provides radial force for primary seal lip 5, prevents running shaft operation, the leakage of sealing oil.Dust excluder lips 6 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 5 of the oil sealing be mated and dust excluder lips 6 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
In order to reduce cost, reduce the frequency of oil seal replacement, promote the sealing effect of oil sealing, the utility model provides a kind of oil sealing of new structure, to sealing lip by structural new design, extends the working life of oil sealing and improves the sealing effect of oil sealing.
The utility model solves the technological scheme that its technical problem adopts: provide a kind of oil sealing, comprise support, skeleton, sealing lip, wherein skeleton is enclosed in support, and described sealing lip comprises a primary seal lip and a secondary sealing lip; Or described sealing lip comprises a primary seal lip and a dust excluder lips, outwards tiltedly outstanding bottom described dust excluder lips relative support body.
Described support outer surface is waveform, and when oil sealing assembles, the oiling of support outer surface, namely described waveform defines an oil groove, just than being easier to during assembling, and can prevent oil sealing resilience, having good locating function.
A spring can be set outside described primary seal lip.
Institute tells outside secondary sealing lip and can arrange a spring.
The beneficial effects of the utility model are: by sealing lip being designed to a primary seal lip and a secondary structure of sealing lip, the running shaft not only sealed it forms the sealing of dual fluid, but also play dust reduction capability, improve the sealing effect of oil sealing and extend the working life of oil sealing.Or sealing lip is designed to a main lip and a dust excluder lips, and bottom its dust excluder lips relative support body outwardly, and dust excluder lips outwardly can prevent main shaft in rotary course polarization, beat thus damage dust excluder lips by pressure, the working life of dust excluder lips can be extended, improve its sealing effect.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Fig. 1 is known oil sealing half sectional view;
Fig. 2 is oil sealing first embodiment half sectional view described in the utility model;
Fig. 3 is oil sealing second embodiment half sectional view described in the utility model;
Fig. 4 is oil sealing described in the utility model 3rd embodiment's half sectional view.
Embodiment
Figure 1 shows that the oil sealing described in foregoing Background Section, be made up of support 1, skeleton 2, spring 3, primary seal lip 5 and dust excluder lips 6, wherein dust excluder lips 6 bottommost and support 1 bottommost are in same plane.
Embodiment 1
As shown in Figure 2, this oil sealing comprises support 1, skeleton 2, primary seal lip 41, secondary sealing lip 42 and two springs 3, wherein, skeleton 2 is enclosed in support 1, primary seal lip 41 is arranged at the top of oil sealing inner peripheral surface, secondary sealing lip 42 is arranged at the bottom of oil sealing inner peripheral surface, and two springs 3 are separately positioned on the outside of primary seal lip 41 and secondary sealing lip 42, and support 1 outer surface is waveform.
When spring 3 to primary seal lip 41 transmit radial force make itself and running shaft interference fit time, the even oil film of one deck can be formed between running shaft and lip, the oil film herein formed not only can be taken away running shaft and lip and to rub the heat produced, and certain tension force can be produced on the surface of oil film, stop the outflow of lubricant oil, play seal action.And when spring 3 to secondary sealing lip 42 transmit radial force make itself and running shaft interference fit time, in like manner, the even oil film of another layer is formed between running shaft and lip, improve the seal action of secondary sealing lip 42 further, and can prevent extraneous dust from entering in lubricant oil, pollute fluid, damage functional features, play dustproof effect.
Described support outer surface is waveform, and when oil sealing assembles, the oiling of support outer surface, namely described waveform defines an oil groove, just than being easier to during assembling, and can prevent oil sealing resilience, having good locating function.
Embodiment 2
As shown in Figure 3, this oil sealing comprises support 1, skeleton 2, spring 3, primary seal lip 41 and dust excluder lips 43, wherein, skeleton 2 is enclosed in support 1, spring 3 is positioned at the outside of primary seal lip 41, primary seal lip 41 is arranged at the top of oil sealing inner peripheral surface, and dust excluder lips 43 is arranged at the bottom of oil sealing inner peripheral surface, outwards tiltedly outstanding bottom described dust excluder lips 43 relative support body.And dust excluder lips 43 outwards tiltedly outstanding make dust excluder lips 43 can prevent main shaft in rotary course polarization, beat thus damage dust excluder lips by pressure, the working life of dust excluder lips can be extended, improve its sealing effect.
Embodiment 3
As shown in Figure 4, this oil sealing comprises support 1, skeleton 2, primary seal lip 41 and dust excluder lips 43, wherein, skeleton 2 is enclosed in support 1, with the difference that embodiment 2 is maximum is, this oil seal structure is without spring, for a kind of structure is more simple, use convenient oil sealing.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model; can not assert that concrete enforcement of the present utility model is confined to these explanations; for the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
Claims (4)
1. an oil sealing, comprises support, skeleton, sealing lip, and wherein skeleton is enclosed in support, it is characterized in that: described sealing lip comprises a primary seal lip and a secondary sealing lip; Or described sealing lip comprises a primary seal lip and a dust excluder lips, outwards tiltedly outstanding bottom described dust excluder lips relative support body.
2. oil sealing according to claim 1, is characterized in that: described support outer surface is waveform.
