Oh thanks for reminding me, I have Metr data
Not too bad, I was hammering it as much as I could

@sofu I never thought my mounts would fit @MorrisHsu gear drives. But I am kinda curious if it would be close or not even.
The space from the front to the mounting surface is 19mm / How far in do the gear drives sit from the end of the hanger? @MorrisHsu
To go further in would require the round part to be larger than the 29mm it is now.
There is 35.7mm of usable axle when using a 70mm shoulder bolt. Longer shoulder bolts could alleviate the issue.

The gear drives sit is 38.7mm from the end of the hanger

If this is data for both motors itās looking really good
One idea, since you are testing so much drives, you make standard test procedure/route that you always try to ride the same way, then itās easy to compare everything

Yeah, I have to figure out a new standard route for testing since I moved to a new place. I used to have one
@lrdesigns maybe you can save @MorrisHsu some work and make an extended pressfit mount for his gearbox

Updateā¦
Updated gear size added thrust bearing

Iām really glad that when I gave my detailed feedback to @MorrisHsu he really listened and updated his design. Itās not my original suggested design change but I believe the big thrust bearing will be even better for keeping the wheel gear in place so the two gears will mesh well. Of course, this new change will be thoroughly testedā¦ I really want this gearbox to be great!

great thing about needle bearings is that the higher the pressure the easier they roll. Same principle is used for cannondale forks.

Roller bearings are used as stock in the fork headset of high end 200kg motorbikes putting out 150hp, or upgraded to where the bike is budget made and they wear out. Very suitable for high load applications
If the axle is not true to the hanger that could be a problemā¦but that would be any bearing

New gears with thrust bearing
They seem to seat way more securely than the old ones. Will test them soonā¦

Will you be able to use these with other trucks, say cRonins? Got dimensions of your truck mounting plate if you donāt mind?

Whatās the use of the thrust bearing?
This is dimensions of truck mounting plate
I only tried installing on Calibre II and TorqueBoards trucks

Because the gear will slippage phenomenon when the torque is high.

Oh, also another question. Iām not a mech-e of any sort, but I thought it was recommended that meshing gears be at least co-prime with one another to prevent excessive wear?
Isnāt that still a thing?
