Classification and use of wave washers, characteristics, advantages role of industrial solutions

Wave washers, also known as wave washers, are regular wave-shaped circular sheets. Generally used to prevent loosening, slow impact, need to have good elasticity and impact resistance, and other properties. A wave washer is an elastic sealing element with a wave shape, often used in mechanical sealing. As a high precision and reliable sealing element, the wave washer is widespread, and professional wave washer manufacturers are the players in wave washer production. Wave washers are located on different sides of the center surface, tangent to the corresponding surfaces of the first or second support surface parallel to the center surface. They are improved by improving their initial compression behavior. The wave washer is a lap elastic washer that can usually be mounted in places with little space, e.g., to pre-stress bearings, reduce the noise of bearing operation, and improve the precision and stability of bearing operation. In addition, there are also a large number of applications in electronic and electrical appliances. The materials are carbon steel, stainless steel, copper alloy, etc.

The use of a waveform washer solution

Wave washers are widely used in the field of mechanical seals, especially in the high precision, high-reliability sealing requirements of the occasion of the traditional plane seals are subject to the influence of stress concentration is prone to fatigue and damage, and the wave shape of the wave gasket elastic wave can make the stress to be reasonably dispersed, thus improving its durability and reliability.

They are widely used in the following fields:

1. Automotive field: as valve chamber seals, water pump seals, and other components.

2. Aviation field: as sealing components of engine, air conditioner, hydraulic system, etc.

3. Electronic equipment field: sealing components for cell phones, computers, cameras, medical equipment, etc.

4. Mechanical industry: as high precision seals for pumps, valves, pressure vessels, etc.

The professional wave washer characteristic solution

Wave washers are a relatively common sealing material, mainly through the corrugated structure used to seal the pipe joints; wave washers have excellent aging resistance. Outstanding ozone resistance, far better than butyl rubber and CR. Good weather resistance and sun exposure for three years without cracks. nr150 days they were cracking, SBR5 days cracking, 70 days fracture. Good aging resistance can be used for a long time at 150℃. Aging resistance is the best in general rubber. Compared with traditional gasket materials, wave washers have the following characteristics:

1. Pressure and abrasion resistance: Because the waveform gasket has been professionally designed, its surface has a wavy structure, which allows it to withstand greater pressure and abrasion and is not easily deformed or broken.

2. Good sealing: The wave washer's corrugated structure is very tight, forming an effective seal in the pipe connection and preventing liquid or gas leakage.

3. Not easy to age: Wave washers are usually made of highly elastic rubber or silicone, which are not easily affected by oxidation, ultraviolet rays, and other factors, resulting in aging, cracks, and other problems.

Because of these characteristics, wave gaskets have a wide range of applications in aviation, automotive, machinery, and other fields. The sealing material can also be applied to various temperatures and pressures, providing higher quality and longer-lasting sealing performance for industrial production. Wave washers are a sealing element of great significance and play a vital role in the production and maintenance of the mechanical sealing field. Therefore, for professional waveform washer manufacturers, it is essential to grasp the relationship between different applications, materials, and media to ensure that the production, preservation, and factory inspection links appear to be a correct and standard solution.

The advantages of wave washers

Wave washer is a member of the gasket, and the scope of application is vast because it has many advantages, with the amount of rebound as the optimization goal; in a careful analysis of the connection system wave washer elasticity optimization design method based on the compilation of the design and calculation software, to be able to meet the standardization of wave washer elasticity and parametric design requirements. Using the finite element analysis method and compression spring back test on the bolt-flange connection with waveform washer in the axial load under the load-deformation response relationship between the calculation simulation and experimental research, the calculation results and test data match, indicating that the proposed finite element analysis model can be well used to study the mechanical behavior of the waveform washer.

Based on considering the creep of the gasket and bolt, the deformation coordination equation of the gasket, bolt, flange, and gasket connection system is established as a static system, and the method of compactness analysis is improved. The results show that the gasket can not only effectively compensate for the system relaxation caused by bolt and gasket creep but also compensate for the flange deflection and bolt tension to a certain extent to effectively solve the problem of medium residual stress drop caused by the gasket under high-temperature conditions.

The role of the waveform washers

1. Wave washers to protect the surface of the workpiece: the central role of wave washers is to prevent the nut from loosening mechanical equipment, mainly placed under the nut. Spring washers are low-cost, easy to install, and can be used only for frequent equipment disassembly for general mechanical products and shaft bearings. Its elasticity and diagonal friction realize the role of the wave washer. They are widely used to prevent loosening of fasteners in frequently disassembled connections. The device is located underneath the nut, which prevents it from loosening, as described in national standards. Wave washers are also used to protect workpiece surfaces.

2. Formation of a stable phosphate film on the surface of multilayer wave washers: Multilayer wave washers are heated in air or directly immersed in a concentrated oxidizing solution to produce a fragile oxide film on the surface of the corrugated spring. Phosphating is usually applied to the surface treatment of carbon steel wave washers with a perfect finish so that it reacts with phosphoric acid or phosphate to form a stable phosphate film on the surface of the wave washers. A wave washer is a kind of open-type elastic washer, usually installed in a place with less space, such as pre-stressing the bearings, reducing the noise of the bearing operation, and improving the precision and stability of the bearing operation. In addition, there are many application materials in electronics, carbon steel, stainless steel, copper alloy, etc.
