Introduction[Power Spring] / [Customized Power Spring]
Power springs are made of rectangular section material, Power springs are wound flat, and have either special retaining holes or bends on both ends. As the length-to-thickness ratio (L/t) increases, the spiral space between coils increases rapidly. To reduce the space required and maintain a reasonable amount of deflection (turns), power springs are retained in some type of housing or case in application.
Feature of Spring
2. T=Material thickness
4. Da=Shaft diameter(recommended)
5. R=inside diameter of holder
6. N=Number of coils
Power spring are mainly used in clock, spring motors for toys. timers, as well as in retractor mechanisms for electrical cords, compressor pipes and seat belts.
