Description
Technical Field
The utility model relates to an oil seal product, in particular to an oil seal device based on single-framework activation, and belongs to the technical field of oil seals of an engine before and after bending and an input shaft and an output shaft of a gearbox.
Background
At present, the design and the manufacturing of engine crankshaft oil blanket, the material selection material of its lip has two kinds, and rubber material is one kind, and one kind is that two kinds of materials of PTFE all have excellent shortcoming, no matter adopt that kind of material all can have certain defect, and PTFE's material is comparatively expensive, can lead to the cost of product higher, and the life of oil blanket is short, and pressure resistance and gas tightness are relatively poor, the installation of being inconvenient for, consequently, need an oil blanket device based on single skeleton activation.
SUMMERY OF THE UTILITY MODEL
The utility model mainly aims to provide an oil sealing device based on single-framework activation, wherein a PTFE lip is adopted on the shaft-holding surface of the lip, rubber AEM is adopted on the back surface of the lip, two materials are combined together through a special process and are molded in a mold, so that integrated molding is achieved, the consumption of PTFE materials is reduced, the production cost of products is reduced, the service life of an oil seal is prolonged, the reliability in the later period is higher, the continuous shaft-holding force can be ensured, the pressure resistance and the air tightness of the oil seal can be improved, the installation is convenient, and the requirement on the assembly condition is lower.
The purpose of the utility model can be achieved by adopting the following technical scheme:
the utility model provides an oil blanket device based on single skeleton activation, includes bent axle, iron skeleton, rubber AEM, lip, PTFE lip and gasket, and the department is equipped with the iron skeleton in the middle of the bent axle outside, and the gasket is installed to iron skeleton top one side, and the axle holding face of lip adopts the PTFE lip, and the lip back adopts rubber AEM, and rubber AEM and PTFE lip inner wall and iron skeleton contact each other.
Preferably, the lip, rubber AEM and PTFE lip are of an integrally formed construction.
Preferably, the iron framework is of an L-shaped structure, and the upper section of the inner wall of the iron framework is sleeved with rubber AEM.
Preferably, the rubber AEM, lip and PTFE lip are of S-shaped configuration.
Preferably, the lip is a rubber lip.
The utility model has the beneficial technical effects that:
according to the oil seal device based on single-framework activation, the PTFE lip is adopted on the shaft-holding surface of the lip, the rubber AEM is adopted on the back surface of the lip, two materials are combined together through a special process and are molded in a mold, so that integrated molding is achieved, the consumption of the PTFE material is reduced, the production cost of a product is reduced, the service life of an oil seal is prolonged, the later reliability is higher, the continuous shaft-holding force can be ensured, the pressure resistance and the air tightness of the oil seal can be improved, the installation is convenient, and the requirement on the assembly condition is lower.
