I was using my Delta 18-36 drum sander this evening and ran a board through too fast (I got distracted). Ended up striping a gear on the conveyor belt motor. I'm looking up parts for the 31-255X and it does not break down the motor. It shows part number 911611 for the whole motor for $330!  I found it elsewhere for $225, but still is outrageous! It's a freking $20 gear set! Does anyone know of a place I might be able to find parts for this Delta motor? |

That sounds REALLY familiar. I just helped a guy elsewhere find that $225 motor, but nobody seems to sell the gears.
You CAN... dare I suggest this? You CAN... carefully glue the gear back together (it doesn't have to be a strong bond, just an accurate one) with THIN CA glue, then make a mold from that, then cast another gear from polyester. All the supplies are at your local art supply store or craft store, or you can use polyester resin from the auto-parts store (it's the same stuff used for fiberglass).
I'd offer to machine you another gear from brass, but I don't have my gear-hobbing stuff put together yet.

The gear didn't just break, it stripped it. No chunks left to glue on. That's what I get for walking off to throw dinner in the oven while the board feeds through.  By the time I got back out (<1 min) it was jumping and by the time I stoped it, it was toast. I'd hate buying a $225 motor when I picked the sander up for $400. The gears look weak, mostly plastic. it happened to be a metal one that striped though. I would tend to think this may happen again with the new motor eventually. |

Maybe if he burnt up the motor he would be willing to sell the gears?  |

It may be worth having a conversation with your local Delta service center. They usually have much better parts lists and parts explosion diagrams than we have access to.

I got an ad at the top of the thread, "Do you want a chance to live and work in the USA".
Referring to the acronym list...
WTF?

Tim,
I haven't been able to join the other forum yet to contact him. Hopefully I will be able to soon. According to the other forum he got a replacement (close) for $55 shipped. Looks like since then the price has gone up to about $90. Still not bad compaired to where I started. Hopefully I can get ahold of him and buy his junk motor from him. That work work out best.

I must've completely missed the motor purchase - he must've written it in a different thread than the one where he was talking about the motor failure. Or maybe a completely different forum altogether.

A gear is a gear. Lots of complicated grometry. Pressure angle, involute profile, number of teeth, adendun, dedendum etc etc
Still - you might be able to take your stripped gear and do some measurments on it - than find a replacement grar at McMaster or some other place that sells gears.
You want to know th eoutside diameter and the number of teeth. Then the thickness and the shaft diameter.
Your gear might have a hub with a set screw - or a key slot or something.
With gear in your hand, a measuring device (I use a digital caliper) and the internet - you sould be able to find a gear.
OK - so - if it too thick, of the hole size is off -- we can get that fixed real easy.
added:
Ohh and BTW - did you CALL Delta to get help? HaHaHa - they are worthless. But you should try anyway. This is why I don't buy Delta tools.

Try Bostongear.com as Leo stated gears are a little complex but you may find what you need at Boston gear.

Good point, Leo - there are a trillion gears out there for sale. One source (a little pricey, but they sell nice stuff) may be www.smallparts.com, although they may not sell one large enough. |

I used to work in a small machine shop right behing the Boston Gear factory. In fact - I was a precision gear cutter. I have cut more gear than most people have even seen. I cut gears for 12 years. I also worked in a company that made gears out of powdered metal. Some people call it "sintered metal". I was a tool designer and I actually caculated the involute profile of the gears we were designing forming tooling to make the gears. Gearing, and gear design was also part of my engineering degree program. Somehow - they just do not seem all that complex to me. Maybe, making them all day every day for 12 years, kinda gets you used to them a little bit. Anyhow - they are readily available - ya just need to find one. Can you take a couple of pics of the stripped one and post it. I am sure we can help you find one if we know what we are looking for. |

Just a thought...
Could the gears be replaced with a belt and pulley arrangement?
