Gearbox / 正齒輪變速箱

thingiverse

This work is a mechanical component that showcases a simple gearbox design. The gearbox was created using SolidWorks' mathematical relationships to establish a parameter file, which allows the gear's parameters to be easily modified. However, it's worth noting that the resulting gear drawing is an approximation and not a true involute gear profile. To create a variable-speed gearbox, I used a simple gear ratio assembly. As long as the gear parameters are accurate, this setup can handle basic transmission tasks without any issues. To enhance the input speed visibility, I incorporated an electric screwdriver as the input shaft speed. During final assembly, some design flaws were encountered. However, through minor modifications, the gearbox was able to function smoothly. This is a common issue that DIY enthusiasts often face, and addressing it will help you understand the underlying principles of part design. Here's a breakdown of the required parts: - Gearbox: 1 - Axis: 1 - Axis bracket: 1 - Input axis: 1 - Output axis: 1 - Frame movement: 1 - Handle: 1 - Wheel: 1 - 10T gear: 3 - 10T gear (modified): 1 - 20T gear: 2 - 30T gear: 4 - Ring 5: 1 - Ring 7: 1 - Ring 15: 1 - Ring 18: 1 - Ring 20: 1 - Ring 30: 2 - M3x0.5x5L screw: 2 - M3x0.5x10L screw: 2 - 2.3x6L rod: 18 - 3.5x10L rod: 1
