A locknut is a kind of nut, a part that is screwed together with a bolt or screw to fix it. This is the original part that all production machinery must use. The locknut is a component that tightly connects mechanical equipment. Through internal threads, lock nuts and screws of the same specification can be connected together. Below weigao bolt factory, you know some methods to prevent the nut from sliding.
The bolt factory tells you that mechanical anti-loosening is to directly limit the relative rotation of the lock nut pair through the lock nut stopper. For example, use open-gear pins, steel wires, and limit washers connected in series. Since the lock nut block has no pre-tightening force, the anti-loosening plug can only work when the lock nut is loosened to the stop position. Therefore, the lock nut cannot actually prevent loosening but can avoid falling.
After tightening, the riveting anti-loosening method uses perforation, welding, bonding, and other methods, so the lock nut pair loses the characteristics of the movement pair, and the connection becomes a non-detachable connection. The bolt factory tells you that the disadvantage of this method is that the bolt can only be used once, and it is very difficult to disassemble, and it must be destroyed before disassembling the bolt pair.
The bolt factory tells you that friction prevention is a widely used method of prevention. This method generates a positive pressure between the lock nut pairs that do not change with the external force, thereby generating friction that can prevent the lock nut pairs from rotating relative to each other. This positive pressure can be achieved by compressing the lock nut pair axially or in both directions simultaneously. Such as using elastic washers, double nuts, self-locking nuts, and plug-in lock nuts.
