Stacked wave spring
prusaprinters
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. Category: Engineering
