Clock Spring

Scroll spring:

The vortex hair bar is also called the power spring. It is made of steel strip. According to its relaxed shape, it is divided into two types: natural-shaped power spring and pre-dynamic power spring. The natural-shaped hair spring is directly wound by steel strip. System, pre-dynamic type of spring (also known as constant force spring), you need to first shape the steel strip, and then roll into a spiral shape in the opposite direction, the shape after the spread is very similar to the letter S, it is also called S Shaped spring. The vortex hair bar needs to have a barrel to limit its outer diameter. The center of the spring is connected with the power shaft. When the external force causes the shaft to rotate relative to the spring, the spring will be wound on the power shaft and store the kinetic energy. When the external force disappears, the spring generates a torque to drive the power shaft, and the kinetic energy stored in the spring is output through the power shaft. Compared with the same specification, the pre-dynamic power spring can store 25%-40% of the torque. Provides more turns in the same space.
