Spur gears as pinion gears


Most spur gears for cars are used for slipper clutches. Are there any hubs for 1/4 inch shafts with set screws? I want to use a spur gear as a pinion gear for a drive system for an airplane. I need a hub that bolts onto a #1972 Super Spur 48 Pitch 72T machined spur gear from Robertson.
Thanks

I would think you would have more luck finding the right combination of gears from an airplane gearbox supplier than from car parts?

What overall ratio are you aiming for with a 72T pinion?

I was looking for 1-1 ratio but limited to about 1.56" between gear shafts. What will work is a 75T 48p to a 72T 48p for the distance I need. But none of these gears have hub that can be secured to a shaft. That is why I need a hub to secure the gear to the shaft.
Also what is the pressure angle on 48P. Is it 14.5 or 20 degrees? Also what is the face width of spur gears?
Thanks

48P gears can come in both P/angle.
Face Width is the width of the gear teeth.

SDPI makes hubs for 48p you can try there.
