Function and Types of washers
Washers are sealing and compensating components that are widely used in various mechanical equipment to provide support, protection, and isolation. The functions of adding washers under screws mainly include the following points:
1. Increase the washer area to enhance the bearing capacity
2. Protect the screw from excessive compression and fracture
3. Prevent the fastener from loosening due to vibration or vibration
Considering the different applications of various mechanical equipment, washers can be classified into stainless steel washers, iron washers, and plastic washers, etc. The following is a detailed introduction:
1. Stainless Steel washers:
Stainless steel washers are a common type of washer. Due to their excellent properties such as corrosion resistance, wear resistance, and high temperature resistance, they are widely used in heavy machinery, such as automobiles and aviation. The surface coating of stainless steel washers can make them more resistant to water, oil, and other chemical erosion.
2. Iron washers:
Iron washers are a commonly used type of washer. Because they are suitable for small and medium-sized mechanical equipment and have excellent performance and reasonable price, they are widely used in many fields. Iron washers have very good environmental protection performance and do not cause pollution to the environment.
3. Plastic washers:
Plastic washers are lightweight washers that are widely used in light machinery equipment and electrical appliances. Plastic washers have advantages such as suspension and vibration reduction, electrical insulation, resistance to chemical corrosion, and small temperature fluctuations. At the same time, plastic materials are inexpensive, so they are a cost-effective and practical part.
How to Choose washers
When choosing washers, the first thing to consider is the required function and application environment. In addition, attention should also be paid to the wear resistance of the material and the applicable temperature range. For example, if used in a high-temperature environment, stainless steel washers are a better choice. When choosing washers, it is also necessary to pay attention to the size of the washer and the screw to ensure a strict match to avoid unnecessary failures.
