Calculations
- Largest force comparison- 15,000 in lb or 173 kg m.
First Order Shaft Torque Calculations
- 1" shafts made of mild steel would break at 3000 ft lb of torque (ref?)
- Minimum torque requirement 200 ft lb, or 28 kg m.
- Precious Plastic Shredder calls for 3 kg m from Lyman_Filament_Maker_Calculations#More
Motor Torque
- Motor Torque Calculator says about 1 kg m for 3000 rpm with 3kW drive as in Treadmill Motor. Compare to 173 kg m for strongest torque relevant to tractor drive as in 15000 In Lb Motors.
- Our goal is in between for now, 30 kg m.
Geardown
Belt Geardown
- Serpentine belt on D=1.3" shaft of Treadmill Motor
