Dial spring assembly guide: Flexible response to multiple needs from compression to energy storage

One of the standout features of disc springs is their versatile application—capable of standalone use or being combined in various configurations to meet complex engineering requirements. Leveraging deep expertise in disc spring technology and guided by the "National Standard for Disc Springs", Jiangsu Sunzo Spring provides a systematic analysis of their combination principles, installation specifications, and lubricant selection, helping you achieve optimal disc spring design.

1、Single versus combined: Strategies for different application scenarios

Single use: usually used for static clamping, anti-loosening and a few reset occasions, using its high stiffness and stable reaction force.

Combination use: Designed to achieve more complex functions, such as energy storage, impact buffering and precision control. Through different combination forms, the force and displacement characteristics of the system can be flexibly adjusted.

2、Combination analysis: joint, overlap, and mixed combinations

Combined configuration (series): The total deformation (displacement) is significantly increased while the single plate load remains unchanged.

Laminated combination (parallel): The bearing capacity is multiplied while the total deformation remains the same.

Hybrid combination (series and parallel combination): can increase the load and deformation at the same time to meet the composite requirements of specific working conditions.

3、Standardized installation and guidance: the cornerstone of ensuring combined performance

To ensure the stable operation of the disc spring assembly, the following specifications must be followed during installation:

Pressure plates and guide pieces: The surface hardness of the pressure plates at both ends and the inner and outer diameter guide pieces should be greater than 55 HRC, and the hardened layer depth should be greater than 0.8 mm to ensure wear resistance.

Guidance clearance: The clearance between inner and outer guide components must be precisely controlled according to the "Disc Spring National Standard" or design specifications to balance guidance accuracy and friction resistance.

4、Lubrication selection: Active control of friction behavior

The active selection of lubrication scheme according to application requirements is the embodiment of advanced disc spring design:

Reduce friction: When reducing friction is required, lubricants such as molybdenum disulfide (MOS2) can be used.

Increase friction: when friction force (such as damping) is needed, shot blasting or cross-met coating can be used.

Self-lubrication process: The advanced surface treatment process can achieve the self-lubrication effect of "the more polished, the smoother", especially suitable for maintenance-free or difficult to lubricate occasions.
