The Washer Has A Vital Effect
Oct 09, 2017


Although the gasket is humble, but it is a vital role, many types of gaskets, different sizes, different materials, play a different role.

The role of the gasket - Increases the area supported by the joint to reduce the pressure at the contact and avoid scratching the surface of the joint when tightening the nut.

Gaskets are usually made of various shapes of thin pieces, used to reduce friction, to prevent leakage, isolation, to prevent loose or dispersed pressure. Seals Many materials and structures have such components, for the implementation of various similar effects. The support surface of the fastener such as a bolt is not large due to the material and the process limitation of the threaded fastener, Seals so that the surface of the member to be joined is protected by the compressive stress of the pressure receiving surface.

The support surface of the fastener such as a bolt is not large due to the material and the process limitation of the threaded fastener, Seals so that the surface of the member to be joined is protected by the compressive stress of the pressure receiving surface. In order to prevent loosening of the connection loops, the use of anti-loose spring washers and multi-toothed locking washers, round nut stop washers and saddles, Seals corrugations and conical elastic washers.

In general, the gasket is mainly used to reduce the pressure, Seals when some parts tighten the axial force is very large, easy to make the gasket into a dish, then you can use the material and improve the hardness to solve.

Washers are generally divided into spring washers and toothed elastic washers. The characteristics of the two gaskets are briefly described below.

1. spring washer: spring washer locking effect in general, important parts as little or no use, and the use of self-locking structure. For high-speed tightening (pneumatic or electric) spring washers, it is best to use surface treatment of the gasket, to improve its wear performance, Seals or easy to friction and heat burned or mouth, or even damage the surface of the connector. For sheet connections, spring washers should not be used. According to statistics, spring washers in the car used less and less.

2. Toothed Elastic Washer: Toothed washer As the name suggests is a number of behers on the gasket, the general connection of tooth-shaped elastic gasket due to large and uniform locking force in the automotive industry to use more, and the spacer is relatively use Less.
