# Application of springs in industrial doors

source：Qianye Precision time：2022-9-14

The constant force spring of the industrial door mainly plays a balancing role and reduces the burden on the motor. The force of the spring is equivalent to the force of the industrial door, which is the most ideal configuration state. If the spring force is too large or too small, it will affect the operation of the industrial door. In severe cases, safety accidents may occur and endanger others.

Constant force springs are often used to provide balance to products, so what is balance?

Constant force springs are most useful in applications that require consistent recoil. Ordinary springs behave according to a mathematical equation called Hooke’s law. Hooke’s law states that the force of a recoil spring in the direction of recoil is equal to the distance the spring is displaced from equilibrium. Simply put, we look at how far the spring is stretched – multiplied by a mathematical constant, the rate of the spring. The recoil direction of the spring is opposite to the stretch direction.

Hooke’s Law does not affect constant force springs because their recoil remains constant throughout their range of motion. Their unique design consists of a thin, coiled steel strip that rests when fully coiled. Constant force springs are loaded when they are partially or fully deployed. When released, the spring springs back, pulling the extended ribbon back and rolling up properly. Since the recoil force is mainly obtained closest to the take-up roll, a constant force is maintained. A constant force spring can be used in place of a weight system, a balancing force is a force or influence that counteracts or checks the opposing force.
When purchasing an industrial door, special attention should be paid to the quality and specification of the spring, whether it matches the industrial door. In addition, the tightness of the spring of the industrial door should be checked frequently during use to ensure the safety of the industrial door. It is recommended to contact the spring manufacturer for constant force springs during the design phase.
