Flat washer and spring washers' function

1. After the spring washer is used to tighten the nut, the spring washer gives the nut an elastic force to resist the nut and make it not easy to fall off. The basic function of the spring is to give the nut a force after tightening the nut, increasing the friction between the nut and the bolt.

2, generally do not use flat washers with elastic washers, (in addition to the protection of fasteners and the surface of the installation surface to consider using flat pads and spring pads).

3. Plain washers are generally used in connection parts where one is soft and one is hard and brittle. Its main function is to increase the contact area, distribute the pressure and prevent the soft crushing of the texture.

The role of the flat washer is: 1, increase the contact area of ​​the screw and the machine 2, to eliminate the damage of the spring washer on the surface of the machine when unloading the screw. When used must be: spring washers - flat washers, flat washers next to the machine surface, spring washers between flat washers and nuts. Flat washers are designed to increase the screw bearing surface. In order to prevent loosening of the screw, the spring washer plays a certain amount of buffer protection when subjected to force. Although flat washers can make sacrificial washers. But more often it is used as a supplementary or flat washer. The spring washer acts as a locking element. If the workpiece hole and the screw diameter diameter (S) are too large, using a flat washer or using a washer directly will not only damage the workpiece, but also the most important thing is that the screw will not only have a stable fixation or connection. Especially some high-strength components. Therefore when using spring washers, flat washers may not be used when the value (S) is within the allowable range.
