Luigi: Gearbox adapter

So I've started to work on the adapter that will allow for the Agni 95-r to be mounted on the gearbox. There are some tricky part that needs to be solved. The flywheel has been modified and it's now 15,5 mm thick and has a diameter of 208,80 mm. The diameter is limited by the size of the clutch.

Gearbox bolt pattern and shaft

There is a pilot bearing in the crankshaft for the shaft coming from the gearbox, shown in the picture above. This bearing needs to be added to the new flywheel hub on the electric motor shaft.

Crankshaft and pilot bearing

I tried to reuse the hub on the crankshaft, by sawing it off, but the crank is hollow and there was not enough material in the hub to fasten it on the shaft of the electric motor.

New hub, lighter flywheel now we need to design the adapter. The adapter must retain the measurement given earlier in the blog regarding distance between flywheel and gearbox, 99mm.

First we will add 15,1 mm thick aluminum plate that contains the bolts that measure up to the bolt pattern on the gear box.

On that plate we will bolt a "ring" of aluminum that will hold the motor at a correct distance from the gearbox.

Agni, hub, flywheel and ring

One thing that we don't want to forget is that we need to be able to attach and remove the hub from the shaft of the Agni. In order for this to work we need a small "service windows" in the ring. The hub will be locked by two bolts aligned with the keyway.
