JR: That's called a bevel gear box. Lots of kinds of them and I've not seen one quite like that. it'll probably take a google search to find something similar...Mel

Thanks for the info. I have a saw that was custom built and it uses these for the feed. Some sort of hydraulic - flex shaft system. It is really cool because it has throttle so you can change speed during the cut.

Chipped teeth or cracked gears can be repaired by welding or a good machine shop can make them BUT they will be pricey. Small parts www.smallparts.com/ may have something if you can figure out the size Dr Joe .

They make a similar device to attach to a hand hand drill to make it a 90 degree unit. I think I saw one at Harbor Freight if you don't mind the less than steller quality of the device. You might also check with Boston Gear. Bob

Grainger.com would be my best guess.

Might be able to cannibalize a 4" angle grinder head? They are generally decent metal and bearings and made to last, and might even be able to modify the cast head to keep it a sealed lube housing....now that I read this it doesn't make sense, but hopefully you get the drift.

Being that your gears appear the same angle and tooth count, the technical name is "miter gears". Bevel gears are of other than 1:1 ratio. Not meaning to be picky, this counts for identification purposes. Had a few free minutes this A.M. to look at Boston Gear catalog; huge selection. Google "Boston Gear" to find a distributor. You'll have to provide a bunch of dimensions or take a gear in for a positive I.D. Hopefully helpful.

pic 1 miter gears pic 4 spur gear pic 6 spline coupling on spur gear
if you do get new ones be careful drilling the new holes thru the gear hubs...the hole will need to be drilled perfectly straight for the roll pins to fit correctly...it also looks like in pic 2 that the miter gears have thrust bearings or thrust washers behind them which makes sense because miter gears try to force their selfs apart from each other when in motion...be sure those go back in behind the new gears.
or you can send it to me...and i can see about getting new gears and getting them installed for you...you pay parts and shipping only...i dont have anything going on right now so turn around will be pretty quick....kev
