Abstract
The utility model relates to an oil seal, which is technically characterized in that: the utility model contains a sealing body, and the sealing body contains a framework, a rubber body and a sealing lip, wherein, the framework is sleeved or wrapped on the rubber body and a supporting body is sleeved on the sealing body. The supporting body is a supporting body that is in interference assembly with a shell body and the sealing body is a sealing body that is in interference assembly with an axis. The utility model has the advantages that the processing precision and the surface finish degree of the axis and the shell body can be reduced, the production cost is reduced, while the production efficiency is promoted, the service life of the rotating axis or the rotating shell body is prolonged, and the good sealing performance is kept, thereby being suitable for the sealing of different working conditions.
Description
Technical field
The utility model relates to a kind of Sealing, specifically, relates to a kind of rotation oil sealing.
Background technique
The independent seal that the structure of the existing oil sealing that is used to seal is made up of skeleton, rubber body and sealing lip or is made up of skeleton, rubber body, spring and sealing lip.During use, axle rotates, but oil sealing do not rotate, so oil sealing produces friction to running shaft or housing, thereby causes shortening spool and working life of housing.Therefore, for reducing friction, also must be strict with the machining accuracy and the surface finishment of axle and housing; Simultaneously, when axle and housing had relative play, oil sealing just can not keep good sealing property.
Summary of the invention
The purpose of this utility model is at the problems referred to above, provide a kind of and can reduce axle and the machining accuracy and the surface finishment of housing, reduce production costs, enhance productivity, not direct friction running shaft or rotary shell, prolong running shaft or rotary shell working life, simultaneously, even axle has relative play with housing, it still can keep the rotation oil sealing of excellent sealing performance.
Mentality of designing of the present utility model and working principle are: sealing mechanism is that the rotation oil sealing is made up of support, seal two-part, a part and axle interference assembling, another part and housing interference assembling, seal the leakage of axle and housing by the interference fit of its internal diameter, external diameter, during use, axle or housing rotate, and oil sealing also rotates, and rely on the structure between oil sealing inside to realize static sealing and dynamic sealing.
The purpose of this utility model is achieved in that and comprises seal, and seal comprises skeleton, rubber body and sealing lip, and the skeleton cover is arranged with support if be coated on the rubber body on seal; Support is and the support of housing interference assembling that seal is the seal that assembles with the axle interference.
The utility model, can be on rubber body sheathed spring.
The utility model has following advantage:
1, by the holding tightly or compress and play seal action of sealing labial surface and skeleton inner side surface or outer side surface, end face, during use, axle or housing rotate, oil sealing also rotates, and can not produce friction to running shaft or housing, thereby have improved spool and working life of housing;
2, form by support, seal two-part, a part and axle interference assembling, another part and housing interference are assembled, thereby can reduce the machining accuracy and the surface finishment of axle and housing, reduced cost of production, have improved manufacturing efficiency;
3, not direct friction running shaft or rotary shell have prolonged working life of running shaft or rotary shell, simultaneously, are end face seals because its relies on, even axle has relative play with housing, still can keep excellent sealing performance;
4, not only be fit to low speed rotation, and it also is suitable for high speed rotating.Owing to himself good air circulation system, its improves and has optimized operating conditions.
The utility model owing to adopt said structure, has the machining accuracy and the surface finishment that can reduce axle and housing, reduces production costs, enhances productivity, prolongs running shaft or rotary shell working life, the advantage of maintenance excellent sealing performance.Be applicable to the sealing of various operating modes.
Following embodiment's accompanying drawings is further described the utility model.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structure principle chart.
Among the figure, 1, with the support of housing interference assembling, 4, with the seal of axle interference assembling, 7, skeleton, 8, rubber body, 9, sealing lip, 13, spring.
Embodiment
With reference to Fig. 1, the skeleton 7 of present embodiment, rubber body 8, spring 13 and sealing lip 9 are formed seal, and skeleton 7 is coated on the rubber body 8, and spring 13 is sheathed on the rubber body 8, and difference with the prior art is to be arranged with support on seal; This support is and the support 1 of housing interference assembling that the sealing body is the seal 4 that assembles with the axle interference.
Performance index of the present utility model:
1, properties of rubber: brittleness temperature is lower than subzero 45 ℃, high temperature resistantly is higher than 180 ℃, the fluorine glue that other performance meets the demands, silica gel or fluorine silica gel, and wear-resisting property is superior;
2, the seal lip of oil sealing does not directly contact running shaft or rotary cylinder-block, can not make them produce wearing and tearing, has guaranteed the precision of running shaft or cylinder body, has improved working life.
The utility model, not only can prolong axle or housing working life, have resistance to high temperature and a resistance to low temperature preferably, be applicable to the high speed rotating occasion again.Simultaneously, utilization end face seal and special oil return sealing mechanism, make axle beat or play can not influence the sealability of oil sealing.Therefore, the rotation oil sealing has the market potential and deep meaning is more arranged on field of sealing technology.
Claims (2)
1. a rotation oil sealing comprises seal, and seal comprises skeleton (7), rubber body (8) and sealing lip (9), and described skeleton (7) cover is characterized in that: be arranged with support on described seal if be coated on the described rubber body (8); Described support is and the support (1) of housing interference assembling that described seal is the seal (4) that assembles with the axle interference.
2. rotation oil sealing according to claim 1 is characterized in that: be arranged with spring (13) on described rubber body (8).
