Industry Solutions for Tapered and Spherical Washers

A tapered washer, or tapered washer, is a mechanical sealing element usually used to seal between a rotating shaft and a stationary part. Its primary function is to prevent the leakage of liquids or gases between the rotating shaft and the static parts. The working principle of the taper gasket is straightforward: it utilizes the elastic deformation of the material to produce a seal. When there is a gap between the rotating shaft and the stationary part, the tapered washer is compressed into this gap. The tapered washer creates a reverse force through this compression, preventing liquids or gases from leaking through the gap. The design of the tapered washer is also essential, as it is usually made of highly elastic metal or rubber materials that provide enough elastic deformation to create a seal. In addition, the geometry of the tapered washer is fundamental; it must correctly match the surface shape of the rotating shaft and stationary parts to ensure a good seal.

Also known as spherical washers, these consist of a male and female washer that, when nested, swivel slightly to compensate for tolerance variations and uneven surfaces. They're suitable for die and fixturing applications.18-8 stainless steel washers have good chemical resistance and may be mildly magnetic. Black-oxide steel washers are mildly corrosion-resistant in dry environments.

Spherical Washers: These are embedded washers used to fill or fill the gap caused by inaccuracy or deformation in the mechanical structure to ensure the safe operation of mechanical equipment. It is made of rubber, steel, or alloy material with the sealing and elasticity of a gasket. Spherical washers have a stopping effect. When fastening, the stress in the bolt axial direction increases the friction between the threads. With this configuration, the object being attached is not easily loosened. Washers are divided into flat washers-C grade, large washers-A and C grade, oversized washers C grade, slight washers-A grade, flat washers-A grade, flat washers-chamfered-type-A grade, high-strength washers for steel structures, spherical washers, tapered washers, I-beam with square bevel washers, channel steel with square bevel washers, standard spring washers, light spring washers, heavy-duty spring washers, internal tooth lock washers, internal serrated lock washers, external tooth Lock washers, external serrated lock washers, single lug stop washers, double lug stop washers, external tongue stop washers, round nuts with stop washers. Washers are commonly used fasteners in machinery. It can play a role in bolts, screws, and other fastening connection parts to disperse the load, increase sealing performance, prevent loosening, and so on. In some particular application scenarios, it is necessary to use tapered washers or spherical washers. In this article, we will discuss tapered and spherical washers' standards in detail.

Tapered Washers Standard:A tapered washer is a Specially shaped washer with a tapered inner circumference. When fasteners are connected, tapered washers provide a larger contact area, spreading the load and increasing the stability of the connection.

Classification of Tapered Washers

Tapered washers can be categorized according to material, shape, and other aspects. The common ones are as follows:

1. Material classification

Metal taper washers are generally made of high-quality stainless steel, iron, and other metal materials with high strength and corrosion resistance. Rubber taper washers are usually made of natural or synthetic rubber materials, with better sealing and waterproofing performance.

2. Shape classification

Single taper washer: the inner circumference is tapered, applicable to the connection between the connector and the connector. Double taper washer: both inner circumferences are tapered, which is relevant to the connection between the connector and the connector, with a larger contact area and better stability.

Dimensional Standards for Tapered Washers

Dimensional standards for tapered washers vary depending on the scenario and material used. Generally, the International Organization for Standardization (ISO) and National Standards (GB) specify the dimensions of tapered washers. For example, in metal tapered washers, the dimensional standards are set according to the inner diameter, outer diameter, and thickness. For example, the ISO 9001 standard specifies that the inner diameter of metal single taper washers ranges from 1mm to 100mm, the outer diameter ranges from 3mm to 120mm, and the thickness ranges from 0.2mm to 20mm.

Performance criteria for tapered washers

Performance criteria for tapered washers can also vary depending on the material and the usage scenario. Generally speaking, the performance standards include the following aspects:

1. Strength standard: metal tapered washers must meet specific strength requirements to ensure they are not deformed or damaged when connected.

2. Sealing standard: rubber tapered washers must have good sealing performance to prevent liquid or gas leakage.

3. Corrosion resistance standard: metal taper washers must have a certain degree of corrosion resistance to adapt to harsh environmental conditions.

4. Temperature resistance standard: taper washers must have a certain degree of temperature resistance to ensure they can still work correctly in a high or low-temperature environment.

Spherical Washers Standard

A spherical washer utilizes a spherical shape with a spherical inner circumference. Spherical washers provide a larger contact area and better stability when connected to fasteners.

Classification of Spherical Washers

Spherical washers are categorized similarly to tapered washers and can be classified according to material, shape, etc. Commonly, spherical washers are organized in the following ways:

1. Material classification

Metal spherical washers are generally made of stainless steel and other metal materials with high strength and corrosion resistance. Rubber spherical washers are usually made of natural or synthetic rubber materials, with good sealing and waterproof performance.

2. Shape classification

Single spherical washer: the inner circumference is spherical, applicable to the connection between the connector and the connector. Double spherical washer: two inner circumferences are spherical, relevant to the connection between the connector and the connector connection, with a larger contact area and better stability.

The size standard of the spherical washer

Dimensional standards for spherical washers also vary depending on the scenario and material used. Generally, ISO and GB will specify the dimensions of spherical washers. In the case of metal spherical washers, for example, the dimensional standards are set according to the inner diameter, outer diameter, and thickness. For example, the ISO 9001 standard specifies that the inner diameter of metal single spherical washers ranges from 1mm to 100mm, the outer diameter from 3mm to 120mm, and the thickness from 0.2mm to 20mm.

Performance criteria for spherical washers

The performance criteria for spherical washers vary depending on the material and the usage scenario. Generally speaking, the performance criteria include strength criteria, sealing criteria, corrosion resistance criteria, and temperature resistance criteria, which are similar to those of tapered washers. Taper and spherical washers are special-shaped washers suitable for some particular fastening connection scenarios. Their standards include dimensional standards and performance standards. By following these criteria, a convenient tapered washer or spherical washer can be selected to improve the stability and sealing performance of the fastener connection. In practice, it is necessary to choose the appropriate material and shape of the washer according to the specific needs to ensure the reliability and durability of the connection.

Spherical washers and taper washers application industry

Tapered washers are commonly used to seal rotating mechanical equipment, such as centrifugal pumps, compressors, generators, etc. Due to their simplicity, reliability, and economy, tapered face washers are widely used in industry.

Face washers are a specially shaped sealing element used in many application scenarios. They are widely used in the automotive, Aerospace, petrochemical, machining, and medical industries. Spherical washers are an essential sealing element with a wide range of application scenarios involving numerous industries and fields.
