Background
R. E. Purvis & Associates, Inc., in conjunction with Rotor Clip, offers a line of wave springs. A wave spring is made from coiled flat wire with waves added to give it a spring effect. Wave springs are superior to coil springs in certain applications because they provide lower work heights with the same force. This not only provides for space savings, but also smaller assemblies that use less materials, lowering production costs.
Problem
While traditional, round wire spring has its place in technical applications, it also has drawbacks. Some of the issues that may arise include:
- Not enough space to incorporate spring height
- Uneven bending load
- Limited range of forces, in consideration of application package requirements
Solution
Advantages of flat wire Rotor Clip wave springs are:
- Space saving in axial direction - 50% of the operating height could be reduced
- Bending load in the wave guarantees 100% axial transmission of load
- "Cling on shaft" as assembly held option
- Low load tolerance at specific work heights
