Washers Are Usually Thin Pieces Of Various Shapes
Jul 28, 2017


Washers are divided into: flat washers-Class C, large washers-A and C, large washers-C-class, small washers-A-level, flat washers-A-level, flat washers-chamfer type-A, steel for high-strength washers, spherical washers, cone washers, I-beam square washers, grooved steel square washers, Seals standard spring washers, light spring washers, heavy spring washers, internal teeth lock washers, serrated locking washers, external teeth lock washers, serrated locking washers, single ear stop washers, double ears stop washers, external tongue stop washers, Stop washers for round nuts

Flat washers generally used in the connector is a soft texture, a hard texture is more brittle, its main role is to increase the contact area, dispersing pressure, Seals to prevent the soft texture of the bad. And spring Washer Spring's basic role is to tighten the nut after the nut to a force, increase the friction between the nut and the bolt! The material is 65Mn (spring steel), the heat treatment hardness is HRC44~51HRC, the surface oxidation treatment.

Chinese (Spring) washer, the card spring is an elastic cushion or a loose washer that prevents loosening of bolts. The working principle of the anti-loose washer is very simple. It consists of two pieces of washers. The outer side is a radial convex surface, and the medial is a helical tooth face. When assembling, Seals in contrast to the medial oblique tooth surface, the lateral radial convex surfaces and the contact surfaces of the two sides are in a occlusal state, and when the connecting parts are vibrated and the bolts are loosened, only two pieces of the inner helical surface of the washer are allowed to be relatively dislocated, resulting in a lifting tension, thus reaching 100% locking.

Washers are usually thin pieces of various shapes that are used to reduce friction, prevent leaks, isolate, prevent loose or disperse pressure. Seals This component is used in many materials and structures for the performance of similar functions. Because of the material of the threaded fastener and the limitation of the process, the supporting surface of the fasteners such as bolts is small, so the surface of the connecting parts is protected by the pressure stress of the bearing surface, and the washer is adopted.

In order to prevent the looseness of the connecting pair, the loose spring washer and the multi toothed locking washer, the round nut stop washer and the saddle shape, waveform and conical elastic washer are used.

In general, washers are mainly used to reduce pressure, when some parts of the axial force is very large, easy to make the gasket into a disc shape, at this time to use materials and improve the hardness to solve.

Washers generally can be divided into spring washers, Seals toothed elastic washers two. The characteristics of these two kinds of washers are briefly described below.

1. Spring Washer: The lock effect of the spring washer is general, the important parts are used or not, and the self-locking structure is adopted. For high-speed tightening (pneumatic or electric) of the spring washers, it is best to use the surface phosphating treatment of the washer, improve its wear-reducing performance, otherwise easy to rub heat and burn or open mouth, or even damage to the surface of the connector. For thin-walled joints, spring washers should not be used. According to statistics, the use of spring washers in the car more and less.

2. Tooth-shaped elastic washer: the tooth-shaped washer, as the name implies, has a plurality of teeth on the washer, generally connected tooth-shaped elastic washers because of the locking force is large and uniform, in the automotive industry, and the use of relatively few.
