Abstract

It has been established that the known expressions for calculating the required number of turns of torsion springs are approximate and do not take into account the physical and mechanical properties of the material from which
the springs are made. Based on the analysis of loading, a formula for calculating the number of turns is proposed. It takes into account the necessary and sufficient number of parameters — the permissible bending stress and the elastic
modulus of the spring material, as well as the torsional deformation index — the limiting angle of twisting. The calculation of the number of turns according to the proposed formula provides the most accurate fulfillment of
the spring strength condition at the maximum load.
