Stacked wave spring

thingiverse

Solidworks model for a parametric stacked wave spring. I created my own wave spring model in Solidworks since I couldn't find one that met my needs, and it will be used in a future design. It should work for extension & compression; my application requires compression. 16 Sep 18: I added more variables to the design. This model consists of three main objects: the wave, the top "washer", and the bottom "washer". The wave geometry is determined by the WaveOD, WaveID, and SectionHeight parameters. Each wave has four contact points on both the top and bottom sides. The top and bottom "washers" can now be adjusted separately from the wave geometry. Here are the variables that can be configured: * WaveOD * WaveID * BottomOD * BottomID * BottomHeight: this parameter controls the thickness of just the bottom "washer" * TopOD * TopID * TopHeight * Overlap: this parameter determines how much each wave will merge with its neighbors for added strength, but at a cost to spring action * SectionHeight * TotalHeight * NumWaves: this parameter specifies the number of desired waves making up the stack; it must be greater than three. The cross-section is a rectangle with a height equal to SectionHeight and a width equal to (WaveOD-WaveID)/2. It remains to be seen how well this design will print or function.
