Function:
Change motors with different diameter shafts, change belt pulleys with different speeds, reduce the purchase of new motors or pulleys to maintain existing components and speed/power requirements.
Adapt the larger wheel holes to the small shaft and work together with the pneumatic crankshaft to increase the crankshaft diameter to accommodate pulleys, gearboxes, etc
