Re: Center to Center Distance in Power Transmission
I have measured a few AndyMark gears for tooth thickness and they have all allowed for .005 to .010 of backlash at standard centers which is about where you want to be these types of transmissions. I would recommend a -.000 to +.003” CD tolerance on gearing.
Just remember a little bit of backlash is a good thing. You will destroy a gearset quickly if they are in a tight mesh.
