I'm trying to analyze a gearbox that has high vibration. It is a Philadelphia gearbox size 6M-HPS-1 with an input speed of 3600rpm, an output speed of 1175rpm and an input/output ratio of 3.01:1.
I've been trying to find out the number of teeth on the gears to help me in my analysis, but the service manuals that our Shops have don't have that info. I've contacted the manufacturer, but so far haven't received a response.
My question: Short of opening the gearbox up, is there a way to determine how many teeth are on each of the gears in the box?
