Questions about spur gears and pinion gears...

[Chadworkz]

Ok, I am trying to find out what the largest spur gear there is available in 32-pitch, 48-pitch, & 64-pitch...and I am also trying to find out what the smallest pinion gear there is available in 32-pitch, 48-pitch, & 64-pitch. Do any of you know for sure? Or can you tell me the largest spur and smallest pinion in each pitch you have ever seen/had? I would greatly appreciate it!

So far, my limited research (searching Tower Hobbies) has turned up the following;

32-Pitch: Largest Spur = 72T
32-Pitch: Smallest Pinion = 6T (RC4WD)

48-Pitch: Largest Spur = 96T
48-Pitch: Smallest Pinion = 12T

64-Pitch: Largest Spur = 111T
64-Pitch: Smallest Pinion = 16T
.

Here ya go...for spurs they have 32p all the way up to 100 tooth, 48p to 150, and 64p to 128 in materials like nylon, acetal, and aluminum.

6 tooth is going to be the smallest pinion you'll find for 32p.
Someone makes a 11 tooth 48p pinion...I have one....but I don't recall where I bought it. I think there is a 10 tooth out there, but not real sure.
I'm clueless on 64p pinions...never had to look for them.

When you're looking, make sure it's for a 1/8" (~3mm) shaft and not for a smaller one meant for the mini or micro motors.

They also sell a pack of 4. 9, 10, 11, and 12 tooth.

You might run into problems with the motor hitting the trans before you get your gear mesh set correctly though. I've had problems with a 12 tooth like that.
