Spur Gear Needed
Spur Gear Needed
(OP)
I'm working on a project that requires meshed gears to synchronize timing belts. Unfortunately, I can't find the gears that will work with the belt pulleys used. The pulleys are 10mm pitch, and that means the module I'll need is ~3.183. A search only gave me a few Amazon listings of such gears. Does anyone know of a US vendor who makes or distributes such gears?
Much appreciated for any help you can give.

Belt pulley ---> shaft ---> spur gear mated to spur gear ---> shaft ---> belt pulley
For my purposes, I need a gear with the same pitch as the belt pulley (Module 3.183).
Of course, with a recent suggestion of redesign this may be a moot point, but I'd still like to find out if anyone in the US makes or distributes such a spur gear.

I just need to find spur gears with Module 3.183 (10mm Circular Pitch), and even better if their made or distributed in the US.

they have a great online sizing tool, good prices, decent delivery.

A crucial part of the full design is that the two pulleys have tangential pitch circles.
@MikeKilroy
Thanks so much. That gives me a great place to start.

Additionally, you may still have a little leeway with gear spacing, depending on your requirements for fit and backlash. If the gears are a skosh small, then your effective pitch circles will still be tangent, but you will have a slightly larger pressure angle. Works dandy. Do it all the time.
