Flat Coiled Heavy Duty Motor Box in Metal Coil Constant Force Power Spring
Constant force spring is a circular section cylindrical spiral spring, the working force is basically unchanged. The spring has long life, reliable working performance and good interchangeability, which has been widely used in many industries.
Material selection. The use of environment and function of constant force spring material must be selected corrosion resistant, high elastic materials, China generally use 3J9 or 3Cr15N 'Mo, also useful 3J21,3J22 and other high alloy materials, but the cost is high, can not be used in large quantities. Constant force spring should be able to work in 140℃ environment. Through a large number of experiments in some units, the 3J9 material constant force spring can fully meet the standard requirements. However, in some turbo-generator sets and other temperature more than 160℃ environment,3J9 and other low alloy materials after short-term work, that is, re-aging, spring part A and part B have lost the ability to recover.
