Torsional Spring Angle 90°/135°/180°

Frequently asked questions about this product

1. How to calculate the load of the torsion spring?

For the calculation of the torsion spring load: the parameters of the torsion spring inner diameter, arm length, wire diameter, initial angle, use angle, force arm, and number of turns are required. Torsion spring load = spring constant × use angle ÷ force arm; torque = spring constant × use angle (Note: A. It is necessary to ensure that the force during installation is sufficient and there is a certain margin, because there will be some friction in the actual situation; B. The load calculated theoretically needs to be more than 20% larger than the actual value. One is the force tolerance, and the second is the actual installation situation.

2. How to determine the rotation direction of the torsion spring

Method for determining the rotation direction of the torsion spring: Looking down at the spring, if the highest circle rotates clockwise, it is left-handed; if the highest circle rotates counterclockwise, it is right-handed (you can simply judge according to this)

3. The maximum use angle of the torsion spring marked on the catalog, if it is used beyond the range, what will happen to the spring?

It is recommended not to exceed the maximum use angle. If the maximum torsion angle is exceeded, the spring will have the risk of plastic deformation (not being able to return to the original angle) or breakage
