Product Description
Product Overview
This product is a wave elastic washer complying with the JB7590 standard, manufactured from 65Mn spring steel and subjected to black oxide surface treatment. Its unique wave-shaped structure can generate significant elastic deformation when axially compressed, providing continuous preload compensation and effectively preventing fasteners from loosening caused by vibration, impact or temperature changes. 65Mn spring steel has a high elastic limit and fatigue strength, and combined with the rust-proof ability of black oxide treatment, it is suitable for fastening and adjustment occasions of mechanical equipment that have high requirements for elastic compensation and fatigue resistance.
Core Advantages
-
High Elasticity and Fatigue Resistance: The 65Mn material endows the washer with high elasticity and excellent fatigue resistance, which can withstand frequent compression cycles.
-
Continuous Preload Compensation: The wave design provides a large elastic stroke, which can effectively compensate for preload loss and has good anti-loosening performance.
-
Adaptability to Uneven Surfaces: The wave structure can adapt to slight unevenness of the connected surface, ensuring uniform pressure distribution.
-
Vibration Damping and Buffering Effect: Elastic deformation can absorb part of vibration and impact energy, playing a protective role for the connected components.
Applicable Industries
-
Power Transmission Systems: Connections with vibration and thermal cycles such as engine cylinder heads, gearbox housings, and reducer flanges.
-
Heavy Mechanical Equipment: Anti-loosening and gap adjustment for high-vibration load parts such as construction machinery, mining machinery, and metallurgical equipment.
-
Mold and Stamping Equipment: Occasions requiring precise preload and anti-loosening, such as stamping molds, injection molding machine templates, and press workbenches.
-
Precision Instruments and Fixtures: Parts that need to maintain constant clamping force, such as precision machine tool spindles, measuring instruments, and tooling fixtures.
-
Rail Transit Equipment: Auxiliary anti-loosening for key vibration parts such as locomotive bogies, braking systems, and traction equipment.
-
Pumps, Valves and Fluid Machinery: Connection points with pressure pulsation such as high-pressure pump and valve flanges, compressor housings, and hydraulic systems.
-
Electronic Product Heat Dissipation Systems: Elastic compression between high-power radiators and chips to ensure good contact of the thermal conductive interface.
Warm Tips
-
During installation, please ensure that the wave peak direction of the washer is correct; usually, its main elastic effect should act on the axial direction.
-
Do not use it beyond the allowable compression amount of the washer (the difference between the free height and the flattened height), so as to avoid permanent deformation or elastic failure.
-
In humid or corrosive environments, the black oxide layer provides basic protection; if the working conditions are harsh, it is recommended to take additional anti-corrosion measures or select stainless steel materials.
