Washer (flat washer, lock washer ,or called single coil spring washer, double lock washer,or called double coiled elastic ring; multi-coil spring washer, or called triple elastic ring) A, Washer overview A washer is a thin plate (typically disk-shaped, but sometimes square) with a hole (typically in the middle) that is normally used to distribute the load of a threaded fastener, such as a bolt or nut. Other uses are as a spacer, spring (Belleville washer, wave washer), wear pad, preload indicating device, locking device, and to reduce vibration (rubber washer). B, Washer types Washers are divided into: I. Plain washer (or "flat washer") flat washers - C level, large washers - A and C level, extra large washers - C level, small washers - A level, flat washers - A level, flat washers - chamfered type - A level, II. Other type washers: steel structure with high strength washers, spherical washers, tapered washers, I-beam with square sloped washers, channel with square sloped washers, standard spring washers, light spring washers, heavy spring washers, inner tooth lock washers, inner serrated lock washers, outer tooth lock washers, outer serrated lock washers, single ear stop washers, double ear stop washers, outer tongue stop washers, round nuts with stop washers. C, Commonly used washers' usage and technical parameters I, Flat washers are generally used in the connection of a soft texture, a hard more brittle, its main role is to increase the contact area, disperse the pressure to prevent the soft texture of the crushed. The basic role of the spring washer is to give a force to the nut after tightening the nut, increasing the friction between the nut and the bolt. Material 65Mn (spring steel), heat treatment hardness of HRC44 ~ 51HRC, by surface oxidation treatment. II, Loosening washer is a washer to prevent the bolt from loosening. Anti-loosening washer works very simply. It consists of two pieces of washers. The outer side is with radial convex surface, and the inner side of the beveled tooth surface. When assembled, the inner beveled tooth surface relative to each other, the outer radial convex surface and the two ends of the contact surface into a bite state, when the connection is subject to vibration, and make the bolt loose tendency, only allow the two washers inner beveled tooth surface relative to the wrong movement, resulting in lifting tension, so as to achieve 100% locking. Spring washer ,also called the spring lock washer. It is available in stainless steel and carbon steel, carbon steel is also known as iron. Generally used sizes are M3,M4,M5,M6,M8,M10.M12,M14,M16, which are more commonly used. III, Spring washer used to prevent the nut from loosening under the nut. In the mechanical design, production to prevent nuts (or bolts) automatically back loose methods are: padded spring washers IV.
