DownloadTo create crank arms with specified dimensions using either a leather cutter or a 3D printer, this tool calculates from the provided values and generates either an SVG (2D) or STL (3D) file of the crank arm. The generated data can be displayed and shared in various applications, making it easy to use with different devices and software.
One of the key features of this tool is the automatic calculation of the balance weight size. Based on the outside diameter of the balance weight, the mass on the crank pin side, and the density of the crank arm material, it calculates the size of the weight required to achieve balance.
Parameters
- Crankshaft diameter (mm): The diameter of the crankshaft.
- Crank pin diameter (mm): The diameter of the crank pin.
- Crank arm length (mm): The length of the crank arm.
- Crank arm width (mm): The width of the crank arm.
- Balance weight radius (mm): The radius of the balance weight.
- Thickness (mm): The thickness of the crank arm.
The generated data can be displayed in conjunction with the application and shared with 3D printers and connected PCs. For size comparison, the underlying square in the visuals represents a credit card.
