Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to an integrated nut with a self-locking function. Background Art

[0002] Self-locking nuts are nut that can self-lock by friction. Ordinary nuts will loosen by themselves due to vibration and other reasons during use. In order to prevent this phenomenon, self-locking nuts were invented. The main functions of self-locking nuts are anti-loosening and anti-vibration.

[0003] The self-locking nut will axially compress and position the component installed on the shaft end. Whether the self-locking nut is loose is related to the stability and reliability of the fixed component during the operation with the shaft. When the self-locking nut is axially compressed and positioned, the component will squeeze the self-locking nut. When the squeezing force is too large, the self-locking nut will be damaged.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
