Product description
Power Spring ,also known as clock springs, are the oldest form of flat spring and the most common type in use today.
It is made by winding the steel strip into a coil, the center of the spring is fixed on the shaft, and the external diameter is limited by a spring box. When the torque acts on the shaft, the spring is wound up and accumulates energy, and when the roll is unwound, deformation energy is released, and the reel is driven to output the working torque.
Power Spring is divided into general shape and pre-stressed shape. Pre-Stressed Power Spring is at least 25% more torque than the general power spring. Those methods are the same.
Power Spring is widely used in various forms of automatic rewinding mechanism.Such as hose reels , auto safety belts, balancers, all kinds of cord rewinders
