Types of Locking Washers - Wedge Locking Washers

Various machines and components are inseparable from fasteners in the connection assembly. Fasteners bring convenience to the machine industry, but it has an inevitable weakness, that is, it will loosen itself during severe vibrations, causing damage or disintegration of components or a complete device, even causing an accident.

The lock washer can prevent the thread from loosening. There are many types of anti-loose washers, such as butterfly washers, saddle washers, spring washers, wave spring washers, etc., commonly known as anti-loose washers.

These types of anti-loose washers are all anti-loose by increasing the static friction force. The low-vibration, light-load, and anti-loose effect in a uniform speed can meet the needs of enterprises. However, under strong vibration, high load and rapid motion, the complete anti-loose effect is not achieved, but the time for the nut and the bolt to loosen is extended.

In order to solve this problem, scientists all over the world have done a lot of experiments and research, and finally broke through the common crimes, breaking the way of using the "pre-tightening force" and enhancing the "friction force" to play the anti-loose effect. The latest anti-loose principle that combines "lifting tension" and "friction" with "geometric wedge angle". This principle is not only used in gaskets, but also in nuts and bolts, thus solving heavy industry fasteners. The loosening problem also solves the cumbersome installation without the need to refer to the screwing torque and the screwing torque.
