How Does A Variable Force Springs Work

Variable force spring, also called variable force clock spring, is a special spring that can change its elastic force during use. It is often used in automatic shelf propellers, cigarette propellers, mechanical clocks, instruments and equipment , Weighing apparatus, toys and other fields.

Working principle: The elastic force of the variable force spring is changed by changing the cross-sectional area, material, number of turns and other factors of the spring to adapt to different work requirements. For example, in mechanical clocks and watches, the variable force spring can change the oscillation period by controlling the swing amplitude of the pendulum, thereby achieving precise timing; in weighing instruments, the variable force spring can adjust the weighing accuracy by changing the elastic force.

The materials used in the CAIYIN variable force spring mainly include stainless steel 301, carbon steel, manganese steel, phosphor bronze, stainless steel wire, etc. Among them, stainless steel and carbon steel have high strength and corrosion resistance, which can ensure the long-term stability of the spring. Manganese steel has better hardenability and mechanical properties, and is often used to make heavy duty springs. Phosphor bronze has good fatigue resistance and corrosion resistance, and is suitable for manufacturing springs with high requirements.

The Features of variable force springs:

1. Adjustability: The elastic force of the variable force spring can be adjusted by changing its structural parameters to meet different work requirements.

2. Stability: The elastic force of the variable force spring remains stable during use and will not change due to vibration, temperature changes and other factors.

3. Space-saving: The design of the variable force spring is compact, which can save installation space and is suitable for use in small equipment or devices.

4. High precision: The variable force spring has high precision, which can meet the needs of high-precision mechanical equipment.

5. Long service life: The variable force spring has a long service life and can maintain stable performance after many cycles.

Applications

Variable force springs are widely used in various mechanical equipment, such as automobiles, airplanes, trains, industrial machinery, etc. In automobiles, variable force springs are used for shock absorbers, suspension systems, door locks, etc.; in aircraft, variable force springs are used for landing gear, control surfaces, etc.; in trains, variable force springs are used for shock absorbers and brakes etc.; in industrial machinery, variable force springs are used in transmission systems, hydraulic systems; And also are used in shelf pusher system etc.
