I think that the load applied to the guide rod will change if the angle of the arm of the torsion coil spring changes, but the guide rod has broken. Is it possible to calculate the load applied to the guide rod?
Spring Newbie, thank you for your contribution!
In the case of a torsion coil spring, the diameter of the coil changes as the angle of the arm changes. Generally, the coil part is twisted in the winding direction, so the coil diameter becomes smaller.
The clearance between the coil and the guide rod is set in consideration of the amount of change in the coil diameter from the twist angle, and when the coil diameter becomes smaller and there is no clearance with the guide rod, a further twisting force is applied and the load is originally applied. It may be that the guide rod was loaded with a rotational movement that it should not have been and it broke. Regarding the load applied to the guide rod, if the clearance between the coil and the guide rod is properly secured, it is considered that the weight of the torsion coil spring + α is applied to the guide rod. Regarding the + α part, it may be possible to infer from various conditions such as the dimensions and torsion angle of the guide rod and torsion spring, but it is difficult to be precise, so the clearance with the guide rod can be properly maintained from the following formula. Thank you!
