Design Considerations For Constant Force Springs Design Consider
There are many design factors that will affect the time and cost needed to manufacture your spring. Therefore, it’s important to work with a manufacturer like John Evans’ Sons that has the knowledge needed in the design phase.Mounting Methods: There are several mounting methods. Your application will determine which mounting method is best for your spring’s design.Material: Material will certainly affect the design and project cost. High temperatures or corrosive environments will also affect the life of a spring and the required material.Diameter and Load: Length, material width, thickness, and coil diameter affect the spring’s load. Increased loads can be obtained by using two or more constant force springs interwound, in tandem, or in other configurations.All of these, plus other technical considerations, need to be discussed and specified prior to creating prototypes. Our design engineering team can help ensure calculations and configurations are exact in the design phase.Our springs are most often used in the following industries and applications:AerospaceMedical devicesWindowsDefenseElectric motorsNot sure if constant force springs can provide the right action for your product? Contact John Evans' Sons for more information.
