how do i match gears that will work together by gear tooth/ spur sizes, i have no clue?
hello, i recently bought some shaft gears for the motors for my r/c tank project, in case you don't know, a shaft gear is the spur gear that goes onto the motor! anyway, i am back to start working on my tank again, and am searching for some large gears , but i have no idea aside from physically comparing the two, of what gear is the correct size for my gear. how do i figure out if two spur gears are compatible or not? someone please help!
