Rectangular cross-section cylindrical spiral compression spring

Compared with circular cross-section cylindrical spiral compression springs, rectangular cross-section cylindrical spiral compression springs have a larger cross-sectional area in the same space, thus absorbing more energy and can be used as heavy-duty springs with high stiffness requirements. On the other hand, the characteristic curve of a rectangular cross-section cylindrical spiral compression spring is closer to a straight line, and the stiffness of the spring is closer to a fixed constant. Therefore, this type of spring is usually used on measuring instruments for specific purposes. Its shape is shown in Figures 12-2-10, where a and b are the lengths of the perpendicular and parallel edges to the spiral centerline, respectively. The other symbols are the same as in the previous section.
