Firstly, the torsion spring shall meet the following specifications: the diameter of the torsion spring shall exceed 4 times the zero point of the rated height; The torsion spring shall have a certain additional schedule at least equal to 50% of the rated static gradient. The number of torsion spring magnet coils shall not be too small, generally not less than 6 coils; Only in this way can the manufacturing of torsional springs ensure sufficient horizontal compressive strength and bending stiffness, make industrial equipment stable, not easy to collapse, have long plasticity, and ensure long-term shock absorption capacity, but this is usually high. The reasonable model and specification shall be selected according to the net weight of the equipment, so as to ensure the full use of the shock absorber and good shock absorption expected effect.
