Abstract

The utility model discloses an oil seal which consists of a rubber body and a framework, wherein the rubber body of the primary lip part of the oil seal is provided with a groove adhered inside with a primary sealing lip which is formed by a polytetrafluoroethylene lip piece. The utility model takes advantages of the unique performance characteristics of high temperature resistance and low frictional coefficient of PTFE materials to improve the overall sealing performance and the service life of the oil seal. The local rather than overall use of PTFE material contributes to the reductions in cost. The oil seal has the characteristics of making full use of the advantages of rubber material and polytetrafluoroethylene, rapid recovery of oil seal deformation, good sealing effect and long service life.

Description

A kind of oil sealing
Technical field
The utility model belongs to back and forth and the oil seal technique field is used in rotation, especially relates to the oil sealing that uses under a kind of high speed, high temperature and the low temperature environment.
Background technique
At present, in the design of reciprocal and rotary oil seal, exist many application schemes, but because the influence of its structural reason and material, thereby cause the accommodation of oil sealing narrow, for example exist the requirement of low temperature resistant, high temperature resistant and low-frictional force on reciprocating oil seal uses simultaneously, what reciprocating oil seal used at present generally is rubber material, and rubber material can not satisfy above requirement simultaneously; And in the use of reciprocal, rotary oil seal, because the oil seal lip that makes of polytetrafluoroethylene (PTFE) sheet is being subjected under the situation that the external force effect causes being out of shape, the rebound elasticity of teflon plate is relatively poor, can not effectively compensate the influence of distortion, thereby cause sealing effect poor, the PTFE oil sealing of using on the market, the whole lip sheet that great majority adopt, manufacture cost is than higher.
Summary of the invention
The purpose of this utility model be to improve the deficiency of prior art and provide a kind of and make full use of that advantage, the oil sealing deformation separately of rubber material and teflon recovers rapidly, the back and forth efficient and rotary oil seal of good sealing effect, long service life.
The purpose of this utility model is achieved in that a kind of oil sealing, is made up of rubber body and skeleton, is characterized in being provided with groove on the rubber body of oil sealing master lip position, is bonded with the primary seal lip that teflon lip sheet forms oil sealing in the groove.
In order further to realize the purpose of this utility model, can be teflon lip sheet at the bonding width a of oil sealing pasta side and rubber body between 0.05mm-2mm.
In order further to realize the purpose of this utility model, can be teflon lip sheet at the bonding width b of oil sealing gas face side and rubber body between 0.50mm-10mm.
In order further to realize the purpose of this utility model, can be to be provided with the spring that is fixed in the spring groove in the oil sealing master lip rubber body outside.
Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model adopts and be provided with groove on the rubber body of oil sealing master lip position, be bonded with the primary seal lip of teflon lip sheet formation oil sealing in the groove, the main body of lip still adopts rubber material, utilized the rubber material good springiness, characteristic that can effective compensatory change, main lip adopts polytetrafluoroethylmaterial material, make full use of polytetrafluoroethylmaterial material itself and have low-frictional force, high temperature resistant, low temperature resistant advantage, effectively solved the different working condition requirement of adaptation that oil sealing can be wider, being provided with spring at the lip position of oil sealing has effectively avoided polytetrafluoroethylmaterial material low after generation deformation because of rebound elasticity again, can not in time rapid restorable shortcoming, the increase of spring simultaneously can better improve the agreeableness at oil seal lip position, increase the validity of sealing, adopt the bonding of local teflon plate, can effectively avoid using the raising of the cost that polytetrafluoroethylmaterial material causes, thereby greatly reduce cost of material because of integral body.
