What is the state of the lock washer after installation?

by:Tronshal     2022-02-17
The lock washers are composed of two pieces of washers. The outside is a radial relief surface, and the inside is a helical tooth surface. When assembling, the inner helical tooth surfaces are opposite each other, and the outer radial raised surface is engaged with the contact surfaces at both ends. When the connector is subjected to vibration and the bolt tends to loosen, only the inner side of the two washers is allowed. The relative dislocation between the helical tooth surfaces generates lifting tension, so as to achieve 100% locking effect. Its anti-loosening principle conforms to military standards. The anti-loose washer is not only an anti-loose locking device, but also a high-load locking device, which can be used in all strong vibration environments. If the lock washers are used and installed correctly, the nuts and bolts do not need to be tightened again, which can ensure the safety of the fasteners. The working principle of the lock washer is very simple. It consists of two washers. The outside is a radial relief surface, and the inside is a helical tooth surface. When assembling, the inner helical tooth surfaces are opposed to each other, and the outer radial raised surface is in an engaged state with the contact surfaces at both ends. When the connecting piece is vibrated and the bolt tends to loosen, only the inner helical tooth surfaces of the two washers are allowed to face each other. Staggered movement will generate lifting tension, so as to achieve 100% locking effect.
