Peerless 100 series gearbox

[Cool Bananas]

I plan to fit an Peerless 100 series gearbox to my flail mower, to counter rotate the flail head. Only gearbox i can find to sit inline between shafts. Its designed for low speed rpm.4 - 600rpm. My thinking is it could cope with 3200rpm as it can manage 300lbs load! (Well built!) So I want to keep it cool as possible. Do you think 5W50 fully synthetic car engine oil and possible welding cooling fins would be enough! Any idea's would be great!
Please see attached photo
Thanks a lot

I can't see the file but I would not weld to a finished gearbox. Distorting the housing is not worth it, and welding fins away from the heat source isn't very useful.

How long will you be running it? If you run it for, say, a half-hour a week it may not matter much.

3200rpm may not cause any issues but how much surplus torque capacity does it have?

Thanks for getting back.
use for couple hours a week, not full time. MINE IS 1" AXLE
UPLOADED FRESH PHOTO. OUTPUT TORQUE IS 150 FT.LBS (204.4n-M) NOT SURE ON SURPLUS.

HERE IS SOME INFORMATION:
• Housing – Die-cast aluminum housings offer
outstanding heat dissipation and durability
• Axle Shafts – 3/4” (19.05 mm) and 1“ (25.4 mm)
diameter with key slots; optional axle lengths and
ends available
• Differential – Automotive-type sintered metal or
optional steel cut bevel gears provide smooth,
long lasting performance
• Bushings – Axle shafts rotate on bronze or oil
impregnated bushings; needle bearings and seals
are available as an option on 3/4” (19.05 mm)
diameter axles
• High Carbon Steel Bolts – Holds housing assembly
together and provides mounting for sprocket;
includes locknuts (4-bolt standard, 6-bolt optional)
• Stamped Steel Sprockets – Standard 40,45,54
or 60 tooth sprockets for number 40 and 41 chain;
shipped separate from differential
• Applications – rear engine riders, go-karts, seeders/
spreaders, electric vehicles, floor sweeper, power
wheelbarrow, and pedicab trikes

Are you proposing to hold the center section stationary and drive one side at 3200RPM to get an opposite rotation output? If so, I expect that differential to fail before you finish the first use, you will be subjecting the gearing to far higher speeds and duty cycle than it was designed for.

Coud you add some idler pullies and get a double V belt and change the direction to the driven pulley?

That's not how gearbox ratings work. The things you have to do to gears to allow them to handle high speeds are not the same as the things you have to do to allow them to handle high torque.

In the grand scheme, 300 ft-lb is not very much.

This gearbox is going to blow up eventually. I would bet it won't take very long.

The original file had "+" characters in the name. While files with those characters can be uploaded, the protocol for downloading doesn't like them.

One can usually use a URL escape character, but that's not working in this case.
