The Working Principle Of Washers Is Very Simple

Although the washer is inconspicuous, it is of great importance, the type of washer is many, the size is different, the material differs, and the effect is different.

The gasket refers to the part between the connecting piece and the nut. Generally a flat-shaped metal ring used to protect the surface of the connected parts from the abrasion of the nut, Seals the dispersed nut to the pressure of the connected piece.

Washers are divided into: flat washers-C-class, large washers-A and C-class, large washers-C-class, small washers-A-level, flat washers-A-level, flat washers-chamfer Type-A-class, steel structure high-strength washers, spherical washers, cone washers, I-beam with square-inclined 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, Seals double ears stop washers, external tongue stop washers, round nuts with stop washers.

Washers are usually thin pieces of various shapes used to reduce friction, prevent leakage, isolate, prevent loose or diffuse pressure. 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, Seals 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, Seals 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. Generally speaking, flat washers are mainly used to reduce pressure, when some parts tighten the axial force is very large, easy to make the washer into a disc shape, at this time to use materials and improve the hardness to solve.

The working principle of washers is very simple. It consists of two pieces of washers. The outer side is a radial convex surface, Seals and the medial is a helical tooth face. When assembling, the medial oblique tooth surface is opposite, the lateral radial convex surface is in a occlusal state with the contact surfaces of the two ends, and when the connecting parts are vibrated and the bolts are loosened, only two pieces of the inner oblique tooth surface of the washer are allowed to be relatively dislocated, resulting in a lifting tension, Seals thus achieving a locking effect of 100%. The principle of the lock is in line with military standards.
