This constant force spring is made of high-quality raw materials. The spring force is long-lasting and constant, non-magnetic, smooth surface and not easy to deform. It is commonly used for the connection of cable shielding layer without welding operation. It is a common accessory for cable installation.
Product characteristic:
1. Short elastic stroke.
2. A certain elasticity is maintained in all strokes.
3. Long service life.
[What is a constant force spring]
It is designed according to the principle of moment balance. Under the allowable load displacement, the load torque and spring torque shall always be balanced. For the pipeline and equipment supported by constant crane, it can provide constant support force in case of displacement, so it will not bring additional stress to the pipeline and equipment. Constant force spring is generally used in places where displacement stress needs to be reduced, such as power industry, suspension parts of steam, water, smoke, air duct and burner of power plant, as well as places where such support is required in petroleum and chemical industry.
Constant force spring is a special tension spring, which is suitable for occasions with large extension and no increase in load.
Constant force springs can produce considerable elasticity. If two or more springs are connected back-to-back or connected in series, the load capacity can be doubled.
The constant force spring is composed of a spiral metal sheet, and the inner side of the metal sheet is bent, so that each circle of metal sheet is tightly wound around a circle of metal sheet inside it. When the sheet metal is stretched (twisted), the internal stress resists the load force, which is exactly the same as that of an ordinary tension spring, but the coefficient is close to constant (zero)
In use, this spring is usually used to tightly wrap around the drum, and its free end is connected with the load, just like a counterweight. But it can also be carried out in reverse, so that the free end is fixed, and the spring itself provides working force, just like the carbon brush in electrical devices.
