How do you put gears and motors together?

Question

I've been trying to do some robotics like work. I can figure out how to put the gears and motors and everything together in my head, but I have no idea how to get everything to actually work physically. Like, how do I get the gear to stay there? How do I mount a motor somewhere? I've been stuck on this sort of thing for a very long time, so any help would be greatly appreciated.

I know the question is really broad, but perhaps a source of information, a book, or something to do as a set of stepping stones, would be helpful.

Answer 1

There are several ways to attach a gear to a motor output shaft.

It mostly depends on your motor shaft and the amount of torque your motor can produce, and the type of gearing you are using (worm gear, planetary, sprocket).

If the shaft is even all the way across (usually the case with small motors such as those used for model train sets, etc) most of the gears are just pressed on and are usually plastic. If not much torque is needed or used you could press the gear on, rough up the outside of the motor shaft and simply apply some high strength glue.

If the motor shaft is tapered then the mating gear must also be tapered and these are most likely pressed fit or heat fitted. Heat fitting usually has one of the best and tightest fits. This is how larger steel train wheels are mounted to the shafts.

Sometimes the motor has a tapered shaft and a threaded end. If this is the case then a nut is used to apply torque to the gear which holds it in place on the tapered shaft. It is also common that the taper has "teeth" which will bite into the softer material of the gear.

If the shaft of the motor looks like a D then you gear either needs to have key that holds it to the shaft or must have the D cutout in the gear also.

If the shaft has a groove cut in the top of it then your gear must also have a groove cut into it, and a square key is used to hold the gear to the motor output shaft.

Sometimes the shafts are special keyed to match special keyed gears. In this case its very hard not to use the gears that were meant to go on it. Such would be the case if your output shaft itself looks like a toothed long gear.

All and all its probably best to find a kit that comes with a motor that will suit your needs and a bunch of interchangeable gears. Try the below site.

Hope this helps some.

Go to the a toy store and buy a K'nex kit. K'nex is a construction kit that will allow you to build just about anything including a simple robot. The kits come with a selection of motors and gears and you can buy additional parts as needed. If the actual robot you are building is large, then you can build a scaled down version using K'nex to prove out your design. Once you have a K'nex model of what you want, then you will have an idea of what you need to build the real thing. You might also want to talk to somebody who is an engineer or a person who works on cars and knows about motors and gears.

I reccommned the book "kickin' bot" by Grant Imahara. As to your motor question, look into keys and keyways- little slots ground into the gear and motor axle, with a metal block put in between them. Mounting a motor somewhere can be done with a hose clamp, so long as you don't crush your motor, or you can bet a motor with a faceplate. Incidentally, the book is for combat bots, so anything it tells you to build is just short of bulletproof. It don't break.

Answer 4

Motors generally come with a flange or bracket for mounting. Gears are attached to shafts using keys, flanges, locking hubs, setscrews, etc. Start looking at some parts catalogs and you should get the idea.

Answer 5

First, go back to Home-Depot, get a drill, screw driver set, a 5 gallon drum of hydraulic fluid, and a really big hammer. Insofar as the motor goes, Duct tape works well for just about everything, get lots of that stuff.

Answer 6

you may have some themes. One is a vacuum leak. You checked each and every of the vacuum strains - yet have you ever checked around the carburetor base, and the intake manifold gasket (the front and rear)? once you've the rubber gasket, they could quite push out of position, causing a leak. the different submit is nice - examine the brake booster - that is hassle-free - plug the line to the booster then positioned it in equipment and be conscious if the idle's not hassle-free - i does no longer propose utilising it, yet an in-equipment try with the e-brake on ought to instruct an progression. you need to also be out of adjustment with the carb - even with the undeniable fact that if it variety of feels to be gentle at idle, you need to properly be mis-adjusted. also - your timing. in case you in straightforward words positioned it mutually, be particular that you've the right vacuum line operating to the distributor (if its reversed, you'd be getting the incorrect signal), and that you've a good initial timing. Timing set in impartial/no load ought to no longer be good if you're in equipment. If all else fails, i ought to nevertheless mistrust the carb, quite if its the former Dualjet, or yet another carb that hasn't been refreshed in a lengthy time period.

If you mean how to make coupling alignment :
1-Adjust vertical and horizontal alignment of coupling flanges , this done after flexible rubber is removed .
2-Adjust angular alignment .
3-Tight all foot bolts firmly .
4-Check again .Readjust if required .
5-Insert flexible rubber .
The most important is to follow manufacturer's instructions or recommendation

your question is to broad ....trial and error i suppose
