Future Gearbox Module

Figured out how to use the roller chain design accelerator in AutoDesk Inventor. Here's all the specs and calculations for the chain & sprockets I put on (The sprockets are the ones we already use, and the chain's now single instead of double.)

Benefits to the New Gearbox Design

The new box has the following benefits:

• The box is totally reversible in any orientation for the four wheels.

• The same motor sits adjacent to the drive shaft instead of in-line, making the box only 20" long instead of 30"
  • This enables us to narrow the wheelbase considerably (which is definitely needed in order to fit the tractor safely on any trailer other than a semi).

• Still modular - you can use it in other applications as well.
  • Gives the option for expansion into narrower wheel-based vehicles (Such as the Car or MicroTrac)

• Allows for potential gear shifting & speedier movement if you want to add different size sprockets

• Stronger and shorter 3" drive shaft instead of 2" (Less likely to break)
  • This also means that using skid steering becomes a viable option again

• Easily serviceable:
  • Both sides are open with plenty of lengthwise room to slip the motor, sprockets, and bearings out if needed.
  • Hydraulic motor inputs/outputs easily accessible.
  • Clamp is essentially just a large C Clamp with two long bolts. When removed, the whole box comes out.
