Solidworks model for a parametric stacked wave spring.
I couldn't find a satisfactory wave spring model in Solidworks, so I made my own. It will be used in a future design. In theory it should work for extension & compression; my application requires compression.
16 Sep 18: Added more variables.
There are three main objects here: the wave, the top & the bottom "washers". The wave geometry is governed by the WaveOD, WaveID, & SectionHeight.
Each wave has 4 top & bottom contacts.
Now the top & bottom "washers" can be manipulated separately from the wave geometry.
Here are the configurable variables:
- WaveOD
- WaveID
- BottomOD
- BottomID
- BottomHeight: or thickness of just the bottom "washer"
- TopOD
- TopID
- TopHeight
- Overlap: how much each wave will merge with its neighbors for strength, at the cost of reduced spring action
- SectionHeight
- TotalHeight
- NumWaves: number of desired waves making up the stack. Must be greater than 3.
The cross-section is a rectangle with SectionHeight as its height, and (WaveOD-WaveID)/2 as its width.
We'll have to see how well this actually prints or functions.
I have not tested it yet.
Future improvement
Add else cases for NumWaves < 4.
