Description
Technical field
The utility model relates generally to pad field, particularly relates to the metallic shim that a kind of wear-resistant seal performance is good.
Background technique
At present, in the seal arrangement acted in most of mechanical system, be all generally use rubber sealing.When carrying out end face seal, need groove or corner angle that fixing cushion rubber is set on part part, otherwise cushion rubber is not easily fixed.The manufacturability of such rubber sealing is comparatively complicated, and vibration resistance is more weak, and the fluid pressure of carrying is lower, and sealing effect is not strong.
Model utility content
The utility model object is exactly the defect in order to make up prior art, provides the metallic shim that a kind of wear-resistant seal performance is good.
The utility model is achieved through the following technical solutions:
The metallic shim that a kind of wear-resistant seal performance is good, include shim body, it is characterized in that: shim body is provided with four cylinder-bore be arranged side by side, the inwall of each cylinder-bore is respectively equipped with asbestos bed course, the inwall of asbestos bed course is coated with teflon seal layer, in each cylinder-bore interval between any two and two ends of shim body are respectively equipped with a mounting hole, wherein one end of shim body outwardly, the other end of shim body is provided with two little water holes, the upper end-face edge of shim body is provided with two small embossments, blind hole is provided with in small embossment, the lower end of shim body is provided with four arc convex corresponding with each cylinder-bore respectively, a positioning hole is provided with in each arc convex.
The utility model has the advantages that:
The inwall of cylinder-bore of the present utility model is provided with asbestos bed course, teflon seal layer, enhances the wear-resistant seal effect of pad, is provided with the positioning hole of arc convex and small embossment and correspondence, blind hole, realizes accurately locating.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
