calculate shaft distance for given 48dp ratio

Hi RC10 world,

is there a calculating tool out there, where you can calculate the required distance of to gear center shafts for given gears?

I need this for an upcoming RC10 Project that I will share when ready.

Thanks, Tony

I'll leave it to those much smarter than myself but you'll need to know the "pitch circle"

Maybe you could have a look at this site:
https://www.engineersedge.com/gear_formula.htm

You can calculate the center distance if you know the number of teeth and the diametral pitch.
As an example, using the equation C=(Ng+Np)/2P, the center distance for a 48DP 20t pinion and its 26t gear would be 0.479".
(26+20)/96 = 0.479"

Ok all I need some help here.

I am designing a new transmission case that is supposed to resemble the stealth as close as possible but is filled with readily available internals no matter what brand.

The boundary conditions (for now) are:

- gears...

I just realized the Rustler / Bandit diff is exactly 45T DUH!! But that is too wide for my taste. I actually have 2 of the ball diffs I could play with but that would be a last resort.

Alternatively I could go completely with gears from a...

I also have the standard front gear (blue). The blue gear was sold separtely, so the there must be a way to mount it on the backgear....

I checked mine today, the counter gear is not the same as yours ED, it is press fitted and not held with a cross pin. As far as I could see it isn't bent.

Hey guys, new to the site, and new to electric rc. Just got a rc10t3 and converted it to a brushless. I ended up with a 5200kv 6.5t motor and was wondering what gearing I should use. Using the stock 87/20 now and seems to top out very fast. Looking...

Just get a temp gun and more pinions. Your tire diameter makes a difference.

forgive me for the stupid question that was probably answered already.

I am really confused as to gear ratio. As some of you have read I have a 10T and a T2. The T2 does not have a transmission, only some parts that came on it. I am trying to...

Last post

Thanks Erich, I have the manuals. I have the original 10T and dowloaded the T2. I just could find anything about how it was different. Thanks for the info though greatly appreciated. I bought my 10T in 93 and mine came with an 87 spur gear. I also...

I'm using a GT trans in my car due to its lay down style. Looking to lower ratio to 2.25 if possible. Will the buggy gears fit the case of the GT trans or is the spacing all wrong?

Last post

New question, is the top shaft gear a press fit gear or is it all one piece? One side looks solid the other looks like 2pc

Edit: spline pressed on gear

Ok, I understand the math to figure this out. What I don't know is what I do with the number I get. 78 tooth spur/24 tooth pinion X 6 gear 1.87=6.08 Now I have this number, what do I use this for or how do I use it?

Cool thanks, I guess I was just over thinking this. :lol:
