Refers to the part between the connecting piece and the nut. A flat metal ring used to protect the surface of the connector from chafing by the nut and to disperse the pressure of the nut on the connector.
Washer is divided into: flat washer - C level, large washers - A and C level, large washers - C level, small washer - A level, flat washer - A level, flat washer - chamfering - A grade, steel structure with high strength gasket, spherical washer, cone washer, beams with inclined washer, channels with oblique gaskets, standard spring washer, light spring washer, heavy spring washers, internal tooth lock pad Ring, inner serrated lock washer, outer tooth lock washer, outer tooth lock washer, single ear stop washer, double ear stop washer, outer tongue stop washer, stop washer for round nuts.
Flat GASKET IS COMMONLY USED IN THE joint is soft texture, it is hard more brittle, its main effect is to increase the contact area, dispersed pressure, prevent the soft texture of the press. The basic function of the spring washer is to tighten the nut to give the nut a force, increase the friction between the nut and the bolt! The material is 65Mn(spring steel), the hardness of heat treatment is HR4~51HRC, and the surface is oxidized.
Washers (spring) washers, spring latches are elastic MATS or latch washers that prevent bolts from coming loose. The principle of operation of the anti-loose gasket is very simple. It consists of two washers. The outer side is with radial convex surface, and the inner side is helical tooth surface. When the assembly, the inner helical surface between the relative, lateral radial convex surface and the two ends of the contact surface into the occlusion state, when the connection is vibrated, and make the bolt loose trend, only allow two washers between the inner helical surface relative dislocation, resulting in lifting tension, so as to achieve 100% locking.
Spring washers are widely used in the bearing and non-bearing structure of general mechanical products, which is characterized by low cost, convenient installation and suitable for installation and disassembly of frequent parts. Washer quick and easy automatic selection has been included, but the spring washer anti release ability is very low! Especially in Europe and the United States countries require high reliability of the product adoption rate is very low, especially the important bearing structure connection parts have been abandoned.
