Yuetong Fasteners Carbon Steel Zinc Plated Lock Nut Blue and White DIN985
1. Mechanical locking. The lock nut stopper makes the lock nut rotate relatively. For example, use an open gear pin, a series wire, and a tab washer. Since the lock nut stop has no pre tightening force, the anti loosening plug will only work when the lock nut is loosened to the stop position. Therefore, the actual lock nut cannot prevent loosening and falling.
2. Riveting and punching to prevent looseness. After tightening by stamping, welding, bonding and other methods, the lock nut pair loses its motion characteristics and the connection becomes an inseparable connection. However, this kind of bolt can only be used once, which is difficult to disassemble. The bolt pair must be destroyed before disassembly.
3. Friction locking, as the most widely used locking method, will produce changes in external forces during locking, resulting in friction that can prevent the lock nuts from rotating relative to each other. This positive pressure can be achieved by simultaneously compressing a pair of jam nuts axially or Bi directionally.
4. Ordinary nuts become loose due to shaking and other reasons during use. Therefore, self-locking nuts are invented to prevent this. The main function of the self-locking nut is to prevent loosening and vibration. The working principle is usually automatically locked by friction, including nut with built-in nylon ring, nut with neck closure and nut with metal locking device.
