Mechanical
- 3" shaft
- 3/4" keyway for motor and implement mounting
- Double-chain coupler for flexible mounting
- Compatible with 15,000 in lb torque and 30,000 lb vertical weight loading when mounted on a vehicle frame (needs CAE)
- Bolt-down wheel mount for easy takeoff and replaceability or universal rotor implements
- Can accept any hub and wheel, such as tubeless truck tire, steel wheels, etc
- Clamp-based axial thrust handling mechanism
Fabrication
- Made from off-shelf parts, only milling required is keyway
- Welded construction
- 6 human hour build time from CNC cut parts to weld, mill, and assemble
Product Ecology
- Builds on existing Universal Rotor frame geometry (proven) with 4 bolt-through or 2 bolt-around mounting to 4" square tubing
- Compatible with CNC Torch Table, Geardown Module of Bulldozer, Power Cube, Biohydraulic fluid, Oil Expeller, LifeTrac, Precision Machining Construction Set, and Induction Furnace infrastructures
- Interchangeable hydraulic motors
Human Factors
- Liftable by a single strong farmer (weight limit 250lb)
- Transparent connection to the frame with 2 or 4 bolts
- Field-serviceable by taking off in the field
Scalability
- Relevant for <1000lb microtractors and >20,000lb heavy equipment such as bulldozers and larger tractors.
- Multiple units of these are attachable to frames for stronger drive
Cost
- $500 prototype cost and $250 production cost goal for materials + hydraulic motor cost
