The working principle of the locknut

  •  

    Anti-loosening nuts are common anti-loosing fasteners. The anti-loose effect is usually achieved by using friction and resistance, of course, this is not the only method. Today, the editor will introduce 4 methods and principles of locking nuts.

    1. Friction prevention

    Friction anti-loose is the most widely used anti-loose method. The principle is to use the pressure generated between the lock nut pair to generate friction that can prevent the lock nut from rotating relative to each other, thereby achieving an anti-loosening effect. Representatives are self-locking nuts, double nuts, and so on.

    2. Mechanical anti-loosening

    The so-called mechanical anti-loosening is achieved by using the lock nut brake to directly restrict the relative rotation of the lock nut pair. For example, our common stop washer is realized by using this principle.

    3. Riveting, anti-loosening

    Riveting and punching prevention is the use of punching, welding, bonding and other methods, so that the lock nut loses the movement characteristics and the connection becomes an undetachable connection. However, this method has disadvantages that cannot be ignored. Not only is the bolt only used once, it is also difficult to disassemble, and the bolts need to be destroyed to disassemble.

    4. Anti-loose structure

    The structure anti-loosening method is also called Down's lock nut anti-loosening method, which uses the characteristics of the thread itself to realize the anti-loosening. Two spirals, left-handed and right-handed, are compounded on the same thread segment, which has the characteristics of both left-handed and right-handed threads, which can be matched with both left-handed and right-handed threads.
