Correct Installation Of Lock Washer
Oct 14, 2022
The lock washer is not only a lock making device for locking, but also a lock making device with high load, which can be applied to all strong vibration environments. If the lock washer is used and installed correctly, the nut and bolt do not need to be tightened again, which can ensure the safety of fasteners. What is the safe installation method of lock washer? Next, let's introduce Xiao Rui.
1. The installation of the lock washer is very simple. It is only necessary to place the internal helical tooth surfaces of the two washers opposite each other between the nut and the connecting material.
2. After the nut is tightened, the radial convex surface on the outside of the lock washer is engaged with the contact surfaces on both ends, and the slope angle of the helical tooth surface on the inside of the washer is greater than the thread angle of the bolt.
3. When the bolt is stretched due to mechanical vibration, the nut will rotate and loosen accordingly. However, the friction of the radial convex surface on the outside of the lock washer is greater than the friction between the internal helical tooth surfaces, so in this state, only the relative dislocation between the internal helical tooth surfaces is allowed to produce lifting tension. The bolt is shrunk by the elongated bolt.
4. When the bolt shrinks, the helical tooth surface of the washer will return the nut to its original position.
5. The lock washer is only suitable for flat and smooth metal surfaces.
6. If the connecting material is non-metallic, a metal plate can be fixed on the connecting material, so that the lock washer can be used.
7. A torque wrench is not required to install the lock washer.
8. Pneumatic tools can also be used when installing or removing lock washers.
