Flat washer
Flat washers are a common mechanical component commonly used to reduce friction, prevent leakage, isolate, prevent loosening, or disperse pressure. They are widely used in various mechanical equipment, especially in bolt or screw connections, playing an important role. The shape of flat washers is mostly circular, but they can also be designed into other shapes according to specific usage needs, such as square, rectangular, or other irregular structures.
The use of flat washers is very extensive, mainly including the following points:
✧ Mechanical field
Flat washers are used to disperse the pressure on screws or bolts, prevent local deformation and sliding, and ensure the tightening effect of connectors. They are also used to connect parts and reduce vibration.
✧ In the field of architecture
In building structures, flat washers help to strengthen material connections, such as between steel bars and concrete, improve the compactness of connections and the ability to resist external forces, thereby enhancing the stability of the structure.
✧ Electrical field
Flat washers are used to connect and support electronic components and equipment, dispersing pressure and avoiding problems caused by force points at the connection points.
✧ Other fields
Flat washers are also used in industries such as vehicle manufacturing, chemical industry, aviation, and aerospace, and play an important role in these fields due to their multifunctional characteristics.
✧ Reduce friction and prevent leakage
Flat washers are used to reduce friction between connectors, fill gaps, increase the tightness of connections, and prevent loosening.
✧ Seal
Flat gaskets play a crucial role in the sealing of pipelines, containers, instruments, and instruments, especially in hydraulic, pneumatic, vacuum, and high-temperature environments. They help prevent spills and pollution, ensuring the normal operation of equipment.
✧ Damping
Flat washers can alleviate mechanical vibration, impact, and noise, protecting the components of mechanical equipment from damage.
✧ Load bearing
They can withstand the weight and torque of machine equipment, ensuring the stability and safety of the equipment.
✧ Adjust
Flat washers can be used to adjust the gaps and positions between mechanical components, ensuring the accuracy and normal operation of the equipment.
✧ Metallic material
Including stainless steel rod, carbon steel rod, aluminum alloy rod, copper rod, etc. Stainless steel flat washers have advantages such as corrosion resistance and good mechanical properties, and are commonly used in industrial fields such as food, pharmaceuticals, ships, and machinery. Carbon steel flat washers are relatively inexpensive, lightweight, and have strong corrosion resistance, making them suitable for use in low load, high temperature, and low-priced applications. Aluminum alloy flat washers have advantages such as light weight, corrosion resistance, and good thermal conductivity, and are widely used in fields such as electronics, aerospace, and rail transit. Copper and brass flat washers have good conductivity, thermal conductivity, and mechanical properties, but their strength is not high, making them suitable for use in low load and low pressure situations.
✧ Plastic materials
Including polytetrafluoroethylene (PTFE), polypropylene (PP), polyurethane, polyester, etc. PTFE flat washers have excellent corrosion resistance, low friction coefficient, and high temperature stability, and are widely used in industries such as pharmaceuticals, food, and chemicals. PP flat washers have good corrosion resistance and low water absorption performance, and are widely used in agriculture, construction, water treatment and other fields.
✧ Composite material
Including copper foil/rubber composite flat washers, steel/rubber composite flat washers, etc.
