What is a light spring rate?
Definition: Coil compression springs with light spring rates based on its physical dimensions. A light compression spring is a spring that might have a small or average wire diameter paired with an outer diameter that corresponds to a spring index no smaller than a 7 to 1 spring index.
What is the difference between compression and extension springs?
One way to describe the primary difference between compression and extension springs is their load at zero deflection. Compression springs have zero load at zero deflection. Extension springs, on the other hand, experience a load at zero deflection due to their initial tension.
How are extension springs rated?
All extension springs have a rate of pounds per inch of extension. Example: Lets say your spring is 10 inches long and has a rate of 10 lbs per inch / of extension . This means if you pull the spring 1 inch in distance it will take you 10 lbs of force to do so.
What is the difference between extension springs and torsion springs?
Extension springs fully expand and contract when operating an overhead door. Torsion springs turn. Torsion springs are sturdier and last longer. Torsion springs do cost more, but generally last between 15,000 and 20,000 cycles, whereas extension springs last up to 10,000 cycles.
What spring rate should I use?
The softer rate will generate a smoother ride while the stiffer spring will result in a firmer ride. You need to consider these options when you are selecting the proper spring rate for your application. Springs should typically be compressed 25-30% of the free length when supporting the weight of the vehicle.
Are longer torsion springs better?
Long Life Torsion Springs By using larger springs, you can, in most cases, quadruple your spring life while only doubling the cost of the springs. You will also avoid extra work down the road. The industry standard is 10-15,000 cycles for new doors.
How do you select a spring?
Choosing a Spring: The Basics
- Sizing. The size of a spring can vary greatly depending on its use, ranging from industrial applications to micro sizes for medical devices.
- Environmental factors. Designers must account for environmental factors that might affect function.
- Stock vs.
Do springs get weaker over time?
A spring under tension for an extended period of time can become weaker. Any object will either resist or deform when subjected to outside stress. Springs are specifically designed to deform in order to absorb energy from outside stress, then return to their natural state when they release that energy.
