Introduction of wave washers

The wave washer is a regular wavy circular sheet, which is generally used to prevent loosening, buffer shock, and has good elasticity and impact resistance.
A simple detection device for elastic index of wave washer, it consists of weight, base, screw, foot, dial indicator and concave groove.

The base is in the shape of a disc, the weights are placed in the upward-facing disc cavity, the middle of the disc cavity is provided with an axial through hole to install the dial indicator rod, the screw locks the dial indicator rod, and the bottom of the base The end faces are supported by the feet.
Wave washers prevent loosening caused by vibration and dynamic load; easy installation and disassembly, and the locking effect is not affected by lubrication; no matter the level of preloading force, it has a good locking effect; it can control the level of preloading force; Same temperature characteristics as standard bolts/nuts; reusable and more.
