Explanation of the method of preventing loosening of the lock nut

Home / News / Industry News / Explanation of the method of preventing loosening of the lock nut

The method to avoid slippage of the locknut is explained mainly by the inner thread. The locknut is the nut, which is screwed together with the bolt or screw for fastening. It is a must for all production machinery. The original part, the lock nut is a part that tightly connects the mechanical equipment. The lock nut and screw of the same specification can be connected together through the inner thread. The following describes in detail two ways to prevent the lock nut from slipping.
Mechanical anti-loosening
The lock nut stopper directly restricts the relative rotation of the lock nut pair. Such as the use of open gear pins, series-connected steel wires and stop washers, etc. Since the lock nut stopper has no pre-tightening force, the anti-loosening stopper can only be effective when the lock nut is loosened to the stop position. Therefore, the lock nut is not prevented from loosening in practice but avoids falling out.
Riveting and anti-loosening
After tightening, using punching, welding, bonding and other methods, the lock nut pair loses the characteristics of the movement pair and the connection becomes an undetachable connection. The disadvantage of this method is that the bolt can only be used once, and the disassembly is very difficult, and the bolt pair must be destroyed before it can be disassembled.
