Lockwashers, also known as check washers. The lockwasher is composed of two pieces, and its unique embedded structure changes the way that the traditional washer is mainly used to prevent looseness by friction, and the tension between the two washers is used to achieve the double effect of loosening and tightening.
The lockwasher has the characteristics of simple installation.
1. Simply place the inner diagonal bevel faces of the two gaskets between the nut and the connecting material;
2. After the nut is tightened, the radial embossed surface on the outer side of the anti-loosening washer is in a meshing state with the contact surfaces at both ends, and the angle of the slope of the inner side of the washer is larger than the thread angle of the bolt;
3. When the bolt is elongated due to mechanical vibration, the nut will rotate loosely. Since the outer radial ridge surface friction of the lock washer is greater than the friction between the inner flank surfaces. In this state, only the relative misalignment between the inner oblique tooth faces is allowed, and then a certain lifting tension is generated;
4. When the bolt is retracted, the beveled surface of the washer will return the nut to its original position. Thereby achieving 100% anti-loosening and tightening effect;
5. The gasket is suitable for relatively flat and smooth surfaces;
6. If the connecting material is a non-metallic material, a metal plate can be fixed on the connecting material, so that the lock washer can be used;
7. No need to use a torque wrench when installing the lock washer;
8. Use pneumatic tools when installing or removing the lock washer.
