Binding AndyMark Toughbox transmission?
Hi.
We are having trouble with binding in one of our AndyMark Toughbox transmissions supplied with the 2008 KOP. It looks like once per revolution of one of the big gears, it is very hard to turn by hand, and if run under motor power, makes a hideous noise. Hard to say for sure, but it looks like the gear might be eccentric. Anyone else having problems like that? Thanks, David Fort Team 1001 Rockwell Automation |

oooh yes, ours is as well..... one of the gears has a ton of play in it............ we even tested ours with a cordless drill, just stuck the shaft into a drill and spun it up, it binded right up..

We had a tight spot on one of our transmissions. Try to see if there is a burr on the gear that needs to be filed down. Also remember to put grease in them. It makes them a lot quieter.

Likely Problems
1) You assembled it wrong. 2) You tightened the bolts too much. 3) You tightened some of the bolts more than others (Anyone who works on cars knows why this is a problem) 4)There is no problem. Spur gears are just really noise, put some grease on them and hook up the CIM, a little wear will break them in. I had trouble turning the toughboxes by hand the first time we assembled ours. After we ran them a little bit with some white lithium grease they worked just fine. |
Re: Binding AndyMark Toughbox transmission?
Are you certain that the little raised parts on the gear faces face the bearings? That is rather important bit that could cause this behavior and is easy to miss.

Re: Binding AndyMark Toughbox transmission?
does the fact that the boxes aren't square bother anyone else?
|
Re: Binding AndyMark Toughbox transmission?
What do you mean they're not square?

Re: Binding AndyMark Toughbox transmission?
ours ended in the scrap pile within two days, on one of them the hole was not big enough for the bearing, and it had to be reamed out a bit. A really shotty part for an expensive KOP.

measure each corner. Ours weren't the same. it was cut at a slight angle and just sanded down. we also had to drill holes in one bigger, and the other didn't even have them. |

Re: Binding AndyMark Toughbox transmission?
Banebot has a problem with their transmissions. The tolerances are off... Sometimes the motor shaft pushes up against the case of the transmission... I have 4 and two of these have that problem. I put a small washer on all 4 screw between the motors and the transmissions. It backs the motor shaft back just a bit but that's all it needs. This creates a gap around the motor to transmission joint, but I can tape that and the unit runs smoothly. If that's not for you, you can try making a spacer gasket with just thick cardboard.
I've done both and they've worked perfectly. I went to the washer because... I'm Lazy... It's a gift. (If you want to find the most efficient way to do something... put your laziest person on it.) Hope this helps Steve (Some of you sound like you might have a different issue... but look in the transmission and see if you are getting small metal pieces or scratches on the inside of the transmission. either of these is the spacing problem. I've worked with 8 Banebot transmissions and this is the only problem but it's a darned consistent one!) |
