Abstract
A high pressure resistant oil seal is composed of a sealing ring, an inner bushing and a sealing layer. The cross section of the sealing ring has a concave shape, the sealing ring is sleeved in the sealing layer, and the inner bushing is connected with the sealing layer at the position of the axle hole of the sealing ring. The utility model has advantages as high pressure resistant, low/high temperature resistant, anticorrosion, strong abilities of antifriction, resisting circular run-out, simple structure, low manufacture cost, and easy assembling.
Description
Technical field
The utility model relates to movable axis seal arrangement field.Relate in particular to the dynamic seal apparatus of hydraulic pressure, air-driven running shaft and reciprocating shaft.
Background technique
At present in hydraulic pressure, pneumatic actuator, shortcoming such as it is good inadequately that the axle envelope that is used for running shaft and reciprocating shaft exists sealability mostly, and anti-high pressure is poor, and frictional force is big between kinematic pair, and working life is short.
The model utility content
The deficiency of shortcomings such as it is good inadequately that the purpose of this utility model is exactly that axle envelope at existing running shaft and reciprocating shaft exists sealability mostly, and anti-high pressure is poor, and frictional force is big between kinematic pair, and working life is short, and a kind of High-pressure oil sealing is provided.
The utility model is made up of seal ring, neck bush and sealing layer, and the section of seal ring is a concave character type, and seal ring set is in sealing layer, and neck bush links to each other with sealing layer at the axis hole place of seal ring.The section of seal ring is an I shape.
The utility model has the advantages that: 1, high pressure resistant, high-low temperature resistant, antifriction quality is strong, and is corrosion-resistant, and anti-circular runout is strong, and wear resistance is good.2, simple in structure, cost of production is low, and is easy for installation.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.Accompanying drawing 2 is for the section of the utility model seal ring is the I-shaped structure schematic representation,
