Lock nut is nut, screw together with the bolt or screw to play a fastening role of the parts, all production and manufacturing machinery must be used as an original, lock nut is the mechanical equipment closely connected parts, through the inner thread, the same specification lock nut and screw, to be connected together.
The superior vibration resistance of the lock nut: when the thread is tightened, the thread of the top of the bolt is tightly inserted into the 30° wedge bevel of the nut, and the normal force generated by the wedge bevel is applied to the axis of the bolt into a 60° Angle, instead of a 30° Angle, so the normal force generated when the lock nut is tightened is much greater than that of the ordinary standard nut, which has a great deal of value Anti-loosening and anti-vibration ability.
The locking nuts are non-metal nested nuts, embedded steel nuts, embedded spring wire nuts, flange indentation nuts, flattening nuts and so on. Non-metal nested nut GB889(that is, nylon lock nut): This lock nut actually has no lock resistance, only some lock resistance. It holds the bolt by the tension of the nylon ring. Embedded steel nut GB6187(metal lock nut): its essence is that the embedded steel sheet is perpendicular to the axis of the nut and parallel to the end face of the nut, and the tooth Angle and pitch of the last button thread are changed by the embedded steel sheet, and the elasticity of the steel sheet itself is used to prevent loosening, and the anti-loosening effect is weak.
