Re: pic: Shaft Drive Bearing Blocks
Efficiency might be your worst nightmare with this system.
Chain & Belt Efficiency ~ 95% - 98% Spur Gears Efficiency ~ 95% - 98% Bevel Gears Efficiency ~ 90% - 95% Planetary Gears Efficiency ~ 80% - 90% Efficiencies multiply for every stage in your gearbox, so for your drive you have spur>planetary>bevel(x2) assuming that your gearboxes are that the top of efficiency you would be getting .98*.95*.90*.90= ~75.4% efficient at transferring torque. This also does not take into account the effects of torsion of your drive shaft on the efficiency. I like the idea and how different it is in application, but sometimes being innovative for no reasons can have adverse effects. That being said I would love to see this drive work, but I would be hesitant to build this for the competition season without building a prototype drive in the off season.
