1. What is a spring washer?
After the connection pair is tightened, the spring washer will rely on its own reaction force to increase the axial tension between the connection pairs and then increase the friction to prevent loosening. Spring washers are widely used in mechanical load-bearing and non-load-bearing structures, and because of their low cost and easy installation, they are more suitable for working conditions that require frequent disassembly and assembly.
Spring washers are often called spring washers in the screw industry. They are made of stainless steel and carbon steel, and carbon steel is also iron. Spring washers are installed under nuts to prevent nuts from loosening. Common spring washers include standard spring washers, light spring washers, heavy spring washers, wave spring washers, conical elastic washers, saddle spring washers, etc.
2. Purpose of spring washers
Our country still has some applications in the military industry, but it has been improved to stainless steel materials.
3. Classification of spring washers
- Internal locking spring washer
Internal locking spring washer is a common spring washer. Its characteristics are: its outer circle and inner circle have a set of locks, which can lock it in the axial direction or hole upward. Internal locking spring washers are usually used for positioning and installation of mechanical accessories, which can effectively prevent the stretching and loosening of steel.
- External lock spring washer
The external lock spring washer is a common spring washer. Its characteristics are: its outer circle and inner circle have a set of locks, which can lock it in the axial direction or hole upward. External lock spring washers are usually used for fixing and sealing mechanical accessories, which can effectively prevent loosening and penetration.
- Flat gasket
A flat gasket is a relatively simple gasket. Its characteristics are: it has only one plane and no elasticity. Flat gaskets are usually used for sealing in static environments. They can effectively prevent the penetration of liquids, gases or particles, but they do not have the functions of shock absorption and anti-loosening.
- Spring leaf washers
Spring leaf washers are a complex type of washers that are characterized by being composed of multiple spring leaves and having very high elasticity. Spring leaf washers can be used in a variety of vibration, shock absorption and sealing situations, but special attention should be paid to their assembly method and the number of spring leaves.
