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

Spring washers are used to prevent loosening. Flat washers do not have a loosening prevention function. Flat washers only increase the contact area. Spring pads are used to prevent vibration from loosening.

The main function of the flat washer is to protect the surface of the connector from scratching the surface of the workpiece when the bolt and nut are tightened; the spring pad is anti-loosening. However, some important connections, such as places that rely mainly on compression to generate friction to transmit power, cannot use spring pads. They reduce the rigidity of the connection and are prone to problems. It is not necessary to use a spring washer. When the strength of the connected parts is low, flat pads or flange bolts are used to increase the contact area. Flat pads mainly increase the contact area. Spring washers are anti-loosening, and are relatively large when there is vibration, pulse, and medium temperature When fluctuating, be sure to use a spring washer. The spring pad can increase the pre-tightening force and has a loosening prevention effect, while the flat washer does not.

Expansion ring of spring washer and cause of hydrogen embrittlement fracture

1. Spring washer ring expansion phenomenon is generally not a problem of the spring washer itself
2. The spring washer that has undergone the expansion ring must be subject to a radial external tension. The external tension results from the tightening axial force generated by the tightening torque.
3. The external chamfer of the bearing surface of the nut produces a radial component of the axial clamping force, thereby expanding the opening of the spring washer. The smaller the chamfer diameter, the greater the possibility of swelling
4. Adding a flat washer between the nut and the spring washer can help slow down or prevent the occurrence of the expansion ring, but the flat washer is too thin or too soft to prevent the expansion ring from occurring
5. The reason for hydrogen embrittlement fracture of spring washers is generally that the heat treatment process is unreasonable and the fracture is caused by the galvanization without dehydrogenation treatment in time.
Extensive experiments and long-term practical experience confirm the above analysis.
