I have stripped out gear from a Delta 31-250 drum sander. The gears are from a 90v DC motor. I know absolutely nothing about gears, but I did take some measurements.
The gear has a larger gear, and a smaller gear built together. The bottom gear outside diameter is 1.35 inches and the smaller gear diameter is .35 inches.
The larger gear has 50 teeth that are angled, and the top gear has 9 teeth that are straight.
The thickness of the larger gear is .19 inches and the total height of the 2 gears is .47 but I have read that the total height isn’t exactly critical for this application.
There is a hole through the center of the gear. The hole measures .110 inches.
I am hoping that one of you guys are able to help. I have had this broken drum sander in my shop for over a year now, and it would be nice to have it back up and running.
