Spring Washers Technical Requirements

The technical requirements of spring washers  include that their manufacture should be in accordance with the specified technical documents, the material properties should be in accordance with the requirements of GB3525, and the limit deviation of thickness should be in accordance with the provisions of P grade.

The specific technical requirements of wave spring washers  are as follows:

Wave springs shall meet the requirements of specific standards and be manufactured in accordance with the approved drawings and technical documents.
The heat treatment and surface treatment of wave springs shall be carried out in accordance with the specified procedures, and the material properties shall meet the requirements of GB3525.
The surface of wave springs should be smooth and clean, free of rust, burrs and cracks, and the oxidized layer should be uniform.
Waveform spring waveform curve should be similar to a sinusoidal curve, the shape of the cross-section should be straight, and the circumferential distribution of each wave peak should be uniform.
The installation dimensions of wave springs should meet the specified requirements.
The specifications of light spring washers  were published by China Standard Press  in 1987, which stipulates the specifications of light spring washers from 3 to 30mm, and were approved and published by the National Bureau of Standards , and began to be implemented in 1988.

These technical requirements ensure the performance and safety of spring washers, which are suitable for use in the load-bearing and non-load-bearing structures of a variety of mechanical products. Although their anti-loosening capacity is low, they are still widely used in parts requiring frequent assembly and disassembly because of their low cost and easy installation.12
