AI Technical Summary
Technical Problem
The existing planar scroll springs have limited fatigue resistance and cannot meet the needs of certain specific scenarios. At the same time, the thicker spring steel will increase torque and reduce the ultimate performance of the material.
Method used
By adjusting the thickness, width and length of the spring steel, the parameters of the coil spring body are controlled to make it thinner, wider and longer, increasing the durability of the coil spring body.
Benefits of technology
The effect of twisting 1/4 cycle stroke life is ≥2 million times, which significantly improves the durability of the scroll spring.

Abstract
The utility model discloses a volute spiral spring structure. The coil spring comprises a positioning part and a rolling part which are arranged on a coil spring body; the effective length of the coil spring body ranges from 1300 mm to 1580 mm, the thickness of the coil spring body ranges from 3.5 mm to 4.3 mm, the outer diameter of the coil spring body ranges from 116 mm to 121 mm, and the number of effective turns of the coil spring body is five. The coil spring body provided by the scheme is thinner, wider and longer, the effect of improving the durability of the coil spring body is achieved, and the coil spring provided by the scheme has the parameter that the stroke life of torsion of 1 / 4 circles is greater than or equal to 2 million times.
