Boardnamics M1-AT Drive | Helical Steel MTB/AT Gear Drive

o meu é uma adaptação do caminhão acedeck nyx, parece-me que entendo um pouco a ideia, o motorista da AT, mas o motorista da engrenagem de rua estava faltando peça

I receive two spur gear models for the motor, which one is for the AT gear driver? one is large with 28 teeth and the other is smaller with 23 teeth? what is the proportion of each


Small = AT drive
Big = m1 street drive

You could also figure this out by calculating the gear ratio.

Looks like you ordered a 3.82 ratio AT drive.

88/23 = 3.82

You’re right friend, that’s right, the biggest gear has 28 teeth but the street M1’s wheel gear didn’t come in the box

@KaramQ @Boardnamics get this man his m1 wheel gears. :grin:

Thanks

Should these be co planar? Got the 1:4.6 pinions which have steps on either side

They’ve been off by that amount for me with every BN I’ve had . Hasn’t been an issue yet.

It’s probably not an issue but that would drive me insane. I’d 100p hit that with a torch add new 648 and reposition it within 1mm

Oh it’s not a single machined piece?

I’ve never used flipskys so the clearance might be different on different motors.

God forbid there be an industry standard

It bothers the hell out of me but at least it leaves the exact right gap to put a thrust bearing in there without needing the Belleville washer so I’ll run it as is

Is the pinion hitting a step on the motor shaft? If so I would run a spacer between motor + drive mounting plate so you can lower the pinion more and line them up

Then the motor doesn’t sink heat to the motor mount plate

If the offset would cause issues I can lathe the ring down, but I’ll only do it if people think it’ll be a problem

You can get/make metal shims which would still help transfer heat. I think you’re probably fine running it as-is also.

@Ac53n had these made for me and a few others, a bit of thermal paste on either side of the spacer also helps a bit.

Hi friend, on your M1 AT, what can you prevent when the wheel is separated from the wheel gear moving towards trans and touching the back of the gear driver and blocking the wheel movement?

Installing the case of the gear drive will solve this, because the case has a bearing in it that supports the gear and keeps it aligned. Without the case, the gear is not fully supported so it can wobble and hit the plate.
