Steel coil torsion springs | Advantages of torsion spring balancing and counterweight balancing
1. The torsion spring balance is based on the principle of balancing the weight of the door body with the torsion torque of the torsion spring. In theory, the torsion spring balance for large industrial doors can be balanced. However, in practice, it is difficult to meet the standard requirements due to the influence of the material of the spring and the manufacturing process.
2. When the area and weight of the door increase, the diameter of the torsion spring and the diameter of the steel wire should be thickened, which will affect the sensitivity of the balance of the torsion spring and increase the difficulty in adjustment.
3. Install torsion spring balance on door openings with large height and width. Due to the limitation of width, it is more difficult to design torsion spring balance. The required size of the torsion spring is also difficult to manufacture, which greatly increases the cost.
4. In large industrial doors, several torsion spring groups or drive shafts are usually used, which will increase the friction and reduce the balance effect.
5. The torsion spring balance will produce a certain degree of fatigue force loss after long-term work, which will make the original balance state with the door body become unbalanced, and increase the working load of the motor.
