In all kinds of mechanical connectors, the anti-loosening of bolts is a very important link. There are many ways to prevent bolts from loosening in life, including using spring washers to prevent loosening. Spring washers are often called spring washers in the screw industry. So why is it frequently used? This depends on the function and principle of the spring washer.
   1. The function of the spring washer:
  The basic function of the spring washer is to give a force to the nut after the nut is tightened to increase the friction between the nut and the bolt! It is an added protective measure to prevent the loosening of the fastening bolt caused by the vibration of the equipment in operation.
  Second, the anti-loosening principle of the spring washer:
  The anti-loosening principle of the spring washer is that after the spring washer is flattened, the spring washer will generate a continuous elastic force, so that the threaded connection pair between the nut and the bolt maintains a friction force and generates a resistance torque, thereby preventing the nut from loosening. At the same time, the sharp corners at the opening of the spring washer are respectively embedded in the surface of the bolt and the connected part, thereby preventing the bolt from rotating relative to the connected part.
