If you're looking to craft custom crank arms with precise dimensions, you can now do so using a leather cutter or a 3D printer. Our tool calculates from your specified values and generates either an SVG file for 2D designs or an STL file for 3D models of the crank arm. These files can be easily displayed and shared with other applications, allowing for seamless integration into your workflow.
One of the standout features is the automatic calculation of the balance weight size. By entering the outside diameter of the balance weight, the mass on the crank pin side in grams, and the density of the crank arm in grams per cubic centimeter, our tool calculates the perfect size for balancing the weight. This ensures your crank arm is not only functional but also perfectly balanced for optimal performance.
Here are the parameters you can customize:
- Crankshaft diameter (mm)
- Crank pin diameter (mm)
- Crank arm length (mm)
- Crank arm width (mm)
- Balance weight radius (mm)
- Thickness (mm)
The generated data can be viewed in conjunction with other applications and shared with 3D printers and connected PCs. For a sense of scale, the underlaying square in the visualizations represents a credit card.
