Overview of cylindrical spiral spring | spiral torsion spring
1、 Structure of cylindrical tension and compression helical spring
Cylindrical spiral spring is divided into compression spring and extension spring. The compression spring is shown in the figure. Usually, the end rings at both ends are tightened and ground flat. There is also a kind of two end rings and tight but not smooth. The smooth part shall not be less than 3 / 4 of the circumference, and the end thickness shall not be less than D / 8.
2、 Geometric dimensions of cylindrical helical spring
The main geometric dimensions of the cylindrical spiral spring are: spring wire diameter D, outer diameter D, inner diameter D1, medium diameter D2, pitch P, helix rising angle α、 Free height (compression spring) or length (tension spring) H0, as shown.
