Crafting crank arms to your exact specifications is now easier than ever with the option to use either a leather cutter or a 3D printer. This tool not only calculates from your input values but also generates precise SVG (2D) or STL (3D) files of the crank arm, making it simple to visualize and bring your design to life.
Once generated, the data can be seamlessly displayed and shared with other applications, enhancing collaboration and production workflows. The tool goes a step further by automatically calculating the size of the balance weight, ensuring your crank arm is perfectly balanced for optimal performance.
To achieve this balance, the tool uses the outside diameter of the balance weight, the mass on the crank pin side (in grams), and the density of the crank arm material (in g/cm³). These parameters allow for a precise calculation of the weight needed to achieve perfect balance.
Key Parameters
- 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 displayed in conjunction with other applications and shared directly with 3D printers and connected PCs, streamlining the production process. For size comparison, the underlaying square in the visuals represents a credit card, ensuring you have a familiar reference point.
