I have this little project in which I am using an electric motor to drive a device with a tapered input shaft.. (technically this is for a hotrod project..but I prefer to NOT give away the details YET) the motor currently has a 6 tooth gear on the drive end which i need to mate to the aforementioned tapered shaft.. I have the capability to machine the tapered shaft portion of a coupler.. and am set up and ready to do so.. however I am having trouble figuring out how I will produce the part of the coupler that will attach to the motors gear.. (as I dont think the eqiptment at my disposal will allow me to keep the tolerances tight enough) I would like to have a coupler that simply slips over the outside of the gear.. however.. I cant seem to determine how I go about measuring the gear to obtain the correct coupler.. does anyone know? or should I be more vague?
Jeff, You need to stop it with this craziness. (1) Can you remove the gear from the motor? (2) Is the gear helical or spur? Do you know what pitch? If you don't know, I can likely measure the gear for you unless it has an odd pitch or is a high contact ratio gear or something strange like that. (3) Have you thought about turning the teeth off the gear and putting the coupling over that? Ed PS- My garage permit was denied, but the zoning officer let me know that I'd likely be able to get a variance on most of the issues.

That last year I built an air powered golf car.I used a 1" air impact (1250 foot pounds of torque). It used a portable air compresser that ran off propane.I did the golf cart just as a test car to see if it would work and so far so go. When I have more time I'm going to build the same setup in a ford ranger pickup and see how it does.I wish I could put some pics. up on here but I'm at work and have no way of uploading pics.plus I'd have to find them all again. The thing I'm getting at here is that when I asked questions I had to watch what I asked, like what you are doing not giving all the details.For one ppl love to flame you for doing something out of the norm.And I did not want someone to still my idea and build it first.
If this is a fairly small motor...I ***ume the device with tapered input isn't a Model A rear end, here...you need to check Small Parts, inc. They have weird couplers, shafts, clutches, internal gears, stuff you never even imagined existed. Their website is pretty good, but get a paper catalog. This is a tool to browse for unexpected solutions. http://www.smallparts.com/ http://www.engineeringfindings.com/index.htm Those two sites appear to be dif routes to same store...another reason to get paper catalog. That plus catalogs for Aircraft spruce, MSC industrial supply, and stock car products will allow you to reset your brain on any engineering product--technology from several utterly different non hotrodder planets.
thanks guys.. I found the solution today.. and with alittle luck I should have the protype functional by weeks end..
Good luck with your project ! Tell us all of your final outcome . Good to here we all have the inventer / car lover inside!
