Re: Large Reduction Single Speed Gearbox
Your target single speed of 7 ft/sec is much lower than is normally used, and with large 8 tires, it pushes it out the required gear ratio to 22.2:1. There are no COTS double reduction gearboxes with that type of ratio.
There are the COTS IR3 Modulux gearbox that you could customize (expensive).
It you had the ability to manufacture a triple reduction gearbox
A (50/12) (60/24) (64/30) = 22.2
12 tooth CIM
Stacked 50 & 24 (CIM drives 50)
Stacked 60 & 30
64 on Output Shaft would do the trick
Spacing is 1.55" CIM Center to First Shaft
2.10" First to Second Shaft
2.35" Second Shaft to Output Shaft
