Performance Characteristics
● High load-bearing capacity: The disc's design allows it to support a greater weight in a more compact area. DIN 2093 spring washers can offer more elastic and support forces in the same installation space as standard flat washers or spring washers, improving the tightness and stability of the connection parts.
● Good buffering and shock absorption performance: When subjected to external impact or vibration, the disc spring washer can absorb and dissipate energy through its own elastic deformation, effectively reduce the transmission of vibration and noise, protect the connection parts, and improve the reliability and stability of the entire mechanical system. It is often used in some equipment or structures with high shock absorption requirements, such as automobile engines, precision instruments, etc.
● Variable stiffness characteristics: To meet varying stiffness needs, different spring characteristic curves can be created by varying the geometric parameters of the disc spring, such as the height of the disc's truncated cone divided by its thickness. This allows DIN 2093 spring washers to adapt their stiffness properties to various technical design requirements based on particular application situations and load requirements. DIN 2093 spring washers with varying specifications or combinations, for instance, can be used to enable flexible stiffness adjustment in mechanical devices that require to alter stiffness based on various operating conditions.
● Compensation for axial displacement: In some connection parts, axial displacement may occur due to manufacturing errors, installation errors or thermal expansion during operation. DIN 2093 spring washers can compensate for this axial displacement to a certain extent, maintain a tight fit between the connection parts, and prevent problems such as loose connection or leakage caused by displacement.
Main application areas of DIN 2093 spring washers
Mechanical manufacturing
DIN 2093 spring washers play a key role in the connection parts of mechanical equipment, especially suitable for mechanical assembly under high vibration and high strength conditions:
● Bolt and nut connection: Improve reliability, prevent loosening, and extend the service life of equipment.
● Typical equipment: Widely used in industrial equipment such as machine tools, construction machinery, mining machinery, etc., to ensure the normal operation of these equipment in harsh environments.
Automobile industry
The demand for spring washers in the automotive field is reflected in improving performance and comfort:
● Engine valve mechanism: Ensure the precise opening and closing and sealing of the valve, and improve engine efficiency.
● Suspension system: Buffer vibration, improve driving comfort and handling stability.
● Other applications: Used for chassis and body connection parts to enhance durability and safety.
Aerospace
The aerospace field has extremely high requirements for the reliability of components. DIN 2093 spring washers have become an ideal choice for key components due to their high precision and high performance:
● Application: Connection structure of core components such as aircraft engines, landing gear, wings, etc.
● Function: Ensure the stability and safety of flight equipment in complex environments.
Electronic equipment
In precision electronic equipment with special requirements for anti-seismic and impact performance, DIN 2093 spring washers can play an important role:
● Fixation and support: Reduce the impact of external vibration on electronic components and improve operational stability.
● Typical equipment: Precision instruments, communication equipment, etc., to ensure long-term service life and stability.
DIN 2093 spring washers have become important components in many industries due to their reliability, performance and ability to adapt to diverse applications. For more technical support or customized services, please contact us!
