Explanation of methods to prevent loosening of anti loosening nuts

The method of preventing the locknut from slipping is explained, which is mainly distinguished by the inner thread. The locknut is a nut, which is screwed together with the bolt or screw to play a fastening role. It is an original part that must be used for all production and manufacturing machinery. The locknut is a part that Tight junction the mechanical equipment. It can be connected together only through the inner thread, the same specification locknut and screw, Below is a detailed introduction to two ways to prevent the anti loosening nut from slipping

Mechanical anti loosening

It directly restricts the relative rotation of the locking nut pair using a locking nut stopper. For example, using toothed pins, serial steel wires, and stop washers. Due to the lack of pre tightening force on the locking nut stop, the anti loosening stop only works when the locking nut is loosened to the stop position. Therefore, in practice, this method of locking the nut does not prevent loosening but rather avoids scattering.

Riveting and anti loosening

Punching, welding, bonding and other methods are adopted after tightening, so that the lock nut pair loses the characteristics of Kinematic pair and the connection becomes inseparable. The drawback of this method is that the bolt rod can only be used once and disassembly is very difficult, requiring the destruction of the bolt pair before disassembly.
