| Questions about spur gears and pinion gears... 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. http://www.servocity.com/html/gears___sprockets.html 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.

Hot racing makes a 9 tooth 48 pitch. http://www.hobbyetc.com/cgi-bin/item.cgi?part_id=35989 They also sell a pack of 4. 9, 10, 11, and 12 tooth. http://www.hobbyetc.com/cgi-bin/item.cgi?part_id=32742 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. |
