The principle of action and characteristics of tapered washers Industry Solutions

Tapered washers have a symmetrical conical or tabular shape and are tapered when viewed from the side. Compared to flat washers, they have a larger outer radius, a smaller inner radius, a larger taper angle, and a thicker wall thickness. The outer surface of a tapered washer is usually flat to accommodate the surface shape of the fastener, and the inner bore is typically round or oval to accommodate the cross-sectional shape of the journal. Tapered washers are a common sealing element that utilizes the tapered surface's shape to achieve a seal. In industrial production, tapered washers are widely used in various mechanical equipment and piping systems and play an important role in sealing—the structure and material of tapered washers.

Tapered Washers Material

Tapered washers are usually made of metallic or non-metallic materials, such as stainless steel, copper, aluminum, rubber, and PTFE. Its structure mainly consists of a tapered surface and a circular gasket. The angle of the tapered surface is usually 30 degrees or 60 degrees, and the diameter and thickness of the circular gasket depend on the needs of different applications.

The principle of action of the taper gasket is to utilize the shape of the taper to achieve sealing. When a gap exists between two connecting parts, the tapered washer fills the gap and thus provides a seal. When the pressure between the connecting parts increases, the tapered washer is compressed, increasing the seal's tightness. At the same time, the tapered shape of the tapered washer allows it to form a conical sealing area between the connecting parts, thus increasing the stability and reliability of the seal. The specific choice of material needs to be determined according to different use scenarios and working environments.

Advantages of Tapered Washers

1. Good sealing: The tapered shape of the tapered washer allows it to form a conical sealing area between the connecting parts, thus increasing the stability and reliability of the seal.

2. High temperature and corrosion resistance: Tapered washers are usually made of metal or non-metallic materials, which resist high temperature and corrosion.

3. Easy to install: Tapered washers have a simple structure and are easy to install and replace.

The disadvantages of tapered washers are:

1. Uneven force: due to the structural characteristics of taper washers, their force is uneven, easy to deform, and tired.

2. Higher cost: Tapered washers are more expensive to manufacture and relatively costly.

Tapered washers are essential sealing elements. They use the shape of the taper to achieve sealing. Tapered washers are widely used in various mechanical equipment and piping systems in industrial production, playing a vital sealing role. Although tapered washers have disadvantages, their advantages still make them irreplaceable sealing elements.

Application Areas of Tapered Washers

Tapered washers are widely used in various mechanical equipment and piping systems, such as automobiles, ships, airplanes, petrochemicals, water treatment, food processing, and other fields. In these fields, tapered washers can play the role of sealing, leakage prevention, shock absorption, buffer, and so on. For example, in automobile engines, tapered washers can be used to seal between the cylinder head and cylinder block to prevent gasoline and water from entering the cylinder, thus ensuring the regular operation of the engine. In the petrochemical field, tapered washers can be used for high-pressure sealing in pipeline systems to prevent oil and gas leakage and ensure production safety.

Advantages and disadvantages of tapered washers.

1. Adjusting the clearance between fasteners and journals

Tapered washers are mainly used to adjust and compensate for the clearance between fasteners and journals, ensuring that the fasteners are tightly fixed on the shaft and ensuring the precision and stability of machine parts. For example, conical washers are often used in machine tools and automobile manufacturing to install components such as wheels, bearings, and gears.

2. Supporting and cushioning journal loads

Tapered washers can also support and cushion the journal load and protect and extend the journal's life. For example, conical washers are widely used in industrial machinery, aircraft, and ships' vibration-damping, anti-vibration, and anti-shaking working environments.
