I pulled these out of a scrap bin at a place I used to work 10 years ago. They are brand new. I don't know what their intended purpose was. They have 7/8" keyed shaft and are 7/8" thick. All of them Stamped MP02877, I get no results googling that. No brand stamped on them. They come in teeth of 39, 37, 33, 31, and 25. I believe They're steel, not cast, as I get a high pitched "ping" when I tap them together.
I'm considering using them in my tractor PTO generator project. Ultimately (extra long term goal, years down the road when I upgrade my tractor to 55hp) I will need to turn 540ft×lbs @ 540rpm into 160ft×lbs @ 1800rpm. For now the max PTO HP my tractor can put out is 32hp, so (shorter, this year) long term goal is turning 310ft×lbs @ 540rpm into 94 ft×lbs @ 1800 rpm. But before I do any of that, I just need to test my generator, make sure it puts out the proper voltage if I can manage to get it up to 1800rpm. I SWAG that will take 5hp max, so say 50 ft×lbs @ 540 rpm into 15ft×lbs @ 1800 rpm.
Will these gears help me accomplish any of those goals? Or are they too weak to even handle 5hp? I just want to know if I'm wasting my time before I go putting a hurt on my brain calculating if the RPM change will work out given the gears I have and the ratios I can create.
