The classification of the gasket(1)

2021-11-25
Gaskets are divided into: flat gasket - class C, large gasket - class A and C, extra large gasket - class C, small gasket - class A, flat gasket - chamfered - class A, high-strength gasket for steel structure, spherical gasket, conical gasket, square bevel gasket for I-beam, square bevel gasket for channel steel, standard spring gasket, light spring gasket, heavy spring gasket, internal tooth lock gasket Internal serrated lock gasket, external serrated lock gasket, external serrated lock gasket, single lug stop gasket, double lug stop gasket, external tongue stop gasket and stop gasket for round nut.

Flat gaskets are generally used in connectors. One is soft and the other is hard and brittle. Its main function is to increase the contact area, disperse the pressure and prevent the soft from being crushed. The basic function of the spring of the spring gasket is to give a force to the nut after the nut is tightened to increase the friction between the nut and the bolt! The material is 65Mn (spring steel), the heat treatment hardness is hrc44 ~ 51hrc, and the surface is oxidized.

Huasi (spring) gasket, snap spring is an elastic cushion or snap lock gasket, a gasket to prevent bolts from loosening. The working principle of the lock gasket is very simple. It consists of two gaskets. The outer side is with radial convex surface, while the inner side is oblique tooth surface. During assembly, the inner oblique tooth surfaces are opposite, and the outer radial convex surface is in an engaged state with the contact surfaces at both ends. When the connector is vibrated and the bolt tends to loosen, only the relative dislocation between the inner oblique tooth surfaces of the two gaskets is allowed to produce lifting tension, so as to achieve 100% locking.
