Standard Type Spring Washer

The standard type spring washer is a commonly used mechanical part. The following is the relevant introduction about it:

Structural Features of the Standard Type Spring Washer

The standard type spring washer is usually in a ring shape and is made of spring steel. It has an opening, which can provide pre-tightening force through elastic deformation during installation.

The cross-sectional shape of the washer is generally circular or rectangular, and its inner diameter matches the diameter of the bolt or screw to ensure that it can fit closely on the threaded connecting part.

Working Principle of the Standard Type Spring Washer

When the bolt or screw is tightened, the spring washer is compressed and undergoes elastic deformation. This elastic deformation generates a reaction force, that is, the pre-tightening force. This force keeps the connecting parts closely connected and prevents the bolt or screw from loosening due to vibration, impact, or other external forces.

Relevant Standards of the Standard Type Spring Washer

GB/T 93-1987: It stipulates the specification dimensions, technical requirements, marking methods, etc. of the standard type spring washer. This standard is applicable to the standard type spring washers with the specifications ranging from M2 to M48, and clearly defines the dimensional parameters such as the thickness, outer diameter, and opening width of the washer, as well as the technical requirements for materials, heat treatment, etc.

ISO 7093-1:2018: It is a standard formulated by the International Organization for Standardization and is widely adopted internationally. It is similar to GB/T 93-1987 and standardizes the dimensions, performance, etc. of the standard type spring washer to promote international trade and product compatibility.

Materials and Properties of the Standard Type Spring Washer

Materials: It is generally manufactured from spring steels such as 65Mn and 60Si2Mn. These materials have high elastic limits and yield strengths, can maintain good elastic properties when subjected to large compressive forces, and are not prone to permanent deformation.

Performance Characteristics: The standard type spring washer has good elasticity and fatigue resistance, and can maintain a stable pre-tightening force during long-term use. At the same time, it also has a certain degree of corrosion resistance and can adapt to different working environments.

Application Fields of the Standard Type Spring Washer

Mechanical Manufacturing: It is widely used in the assembly of various mechanical equipment, such as machine tools, automobiles, ships, etc. It is used to connect various components to prevent bolts or screws from loosening due to vibration during the operation of the equipment, ensuring the reliability and safety of the equipment.

Electrical Equipment: It is also frequently used in the installation and maintenance of electrical equipment. For example, it is used to fix electrical components, connect wires and cables, etc., to ensure the stability of electrical connections and prevent problems such as excessive contact resistance and heating caused by loosening.

Construction Engineering: The standard type spring washer is also used in the connection parts of some building structures, such as the connection of steel structures and the fixing of pipelines. It can effectively prevent the connecting parts from loosening under the action of external factors, improving the stability and safety of the building structure.
