Abstract
The invention discloses a dissection-type framework oil seal which includes a dissection-type annular sealing main body, a hard framework is equipped in the sealing main body, a spring is arranged at an inner lip of the sealing main body, an elastic body hoops at outside of the sealing main body, length of the sealing main body is longer than that of the hard framework, and end surface at dissection part of the sealing main body covers end surface of the hard framework. Compared to the prior art, the dissection-type framework oil seal is convenient for mounting and exchanging and has better oil seal integral rigidity and sealing effect.
Description
Technical field
The utility model relates to the closing element that is used for rotary component, particularly a kind of split type outside framework oil seal.
Background technique
Modern industry production exists a large amount of speed reducers and bearing housing, the conventional seals element in these equipment---and outside framework oil seal lost efficacy fast, changed frequent; and need when changing equipment downtime is disintegrated; time-consuming, the then general insufficient strength of existing split type oil sealing, using effect is bad.
The model utility content
Problem at the prior art existence, the purpose of this utility model is to overcome above-mentioned shortcoming, a kind of installation is provided and changes oil sealing other parts that need not disintegrate, can directly it be taken off or load onto from axle, ensure the split type outside framework oil seal of oil sealing integral rigidity and sealing effect simultaneously.
The technical scheme in the invention for solving the technical problem is: a kind of split type outside framework oil seal, it comprises the split type annular seal body, be provided with hard skeleton in described sealed body, be provided with spring at the epipharynx of described sealed body, sealed body binds round flexible body outward.
Described split type outside framework oil seal, the length of described sealed body are greater than the length of the hard skeleton in being arranged on, and the end face at described sealed body subdivision place covers the end face of hard skeleton.
Described split type outside framework oil seal, described sealed body subdivision mouth section are U type, V-type or straight mouth.
Described split type outside framework oil seal, described spring are helical spring or V-type spring.
Described split type outside framework oil seal, described outer hoop elastomer is helical spring or rubber tape.
The utility model has kept traditional outside framework oil seal good rigidity, withstand voltage high advantage owing to the hard material with hardness height, good springiness is a skeleton, has also ensured the rebound elasticity behind the subdivision simultaneously.In addition, the length of sealed body is greater than the length of the hard skeleton in being arranged on, and the end face at described sealed body subdivision place covers the end face of hard skeleton, and the subdivision mouth place of skeleton on sealed body do not exposed, the subdivision place is the gel phase extruding like this, guarantees the sealability at subdivision place.In addition, because the subdivision mouth of sealed body adopts straight mouthful of bonding or U type, V-type butt joint, and outer hoop has big spring, and it is accurately fixing to make that sealed body subdivision mouth obtains, and do not misplace, thereby ensured the sealing of oil sealing.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the longitudinal sectional view of Fig. 1.
Embodiment
As shown in Figure 1, 2, in the annular seal body 1 of split type, be provided with the skeleton made from the hard material of hardness height, good springiness 2, sealed body 1 is provided with subdivision mouth 5, epipharynx at sealed body 1 is provided with spring 4, spring 4 can be helical spring or V-type spring, the flexible body 3 of sealed body outside hoop.
The utility model is compared with traditional oil sealing, and it is convenient install to change, and oil sealing integral rigidity and sealing effect are better.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
