Spring washers

Spring washers are widely used in the load-bearing and non-load-bearing structures of general mechanical products, which are characterized by low cost, easy installation, and are suitable for frequent assembly and disassembly.

The spring washer can play the function of anti-loosening and increasing the preload, while the flat washer does not have this function, it can be used to increase the fastening contact area, prevent the friction between the bolt and the workpiece, and protect the surface of the connector to prevent the bolt nut from scratching the surface of the workpiece when the bolt nut is tightened.

However, some important connections, such as those that mainly rely on compression to generate friction to transmit power, can not use spring pads, which will reduce the rigidity of the connection and are prone to accidents. When the strength of the connected parts is low, flat washers or flange bolts are used to increase the contact area, and spring washers are used when there are vibrations, pulses, and relatively large fluctuations in the temperature of the medium.
