Night Train Posted December 17, 2009 Share Posted December 17, 2009 I know this is a bit OT but it will be for an 'off road' vehicle project, albeit a small one using an electric motor and a Lada Niva transfer box. I want to get a splined shaft that is 3/4" diameter with 10 splines to fit into a female spline on the motor. Does any one know of anything that is cheap and easily available that would have a spline like this? Pump? Gearbox primary? Half shaft? Machine? Masonary drill bit? Tractor PTO? I figured that if anyone would know it would probably be someone on here. Thanks. NT Quote Link to comment Share on other sites More sharing options...
zoltan Posted December 17, 2009 Share Posted December 17, 2009 What kind of spline? Is it an involute spline like a gear tooth profile or a key spline: straight sided. Post a photo with the major and minor diameters, assuming the major is .750" from what you have stated Quote Link to comment Share on other sites More sharing options...
Night Train Posted December 17, 2009 Author Share Posted December 17, 2009 This is the best photo I have at the moment, I will post a better one tomorrow evening with the dimensions. Thank you. Quote Link to comment Share on other sites More sharing options...
ejparrott Posted December 17, 2009 Share Posted December 17, 2009 What about the shaft that was originally intended to go in there? Quote Link to comment Share on other sites More sharing options...
Night Train Posted December 17, 2009 Author Share Posted December 17, 2009 What about the shaft that was originally intended to go in there? The motor was originally for a golf buggy. I don't have it or know what make or type it should have been. I don't even know if it was ever fitted to one as the motor was given to me. The motor doesn't have a drive end plate as it fitted directly to a gearbox sharing the gear shaft bearing. The male splines would have been the gearbox input shaft. I am just looking for something else to fit that is easily available. I'll post some close up photos and the measurements later on tonight. Thanks.

Night Train Posted December 18, 2009 Author Share Posted December 18, 2009 OK, I had a proper measure of it to get a good average reading over a number of splines to be sure. The major diameter is 19mm The minor diameter is 16.4mm The splines look like this: Quote Link to comment Share on other sites More sharing options...
zoltan Posted December 18, 2009 Share Posted December 18, 2009 My Boys Book of Knowledge (Machinery's Handbook) would say this is an SAE 10 spline, a key spline with a 10B slide/no load fit. They give a major of .749/750" and a minor .644/645" with a key width of .115/117" What uses this? Can't help there. Try these people www.ondrives.com They'll do one offs and have a large range of standard parts, maybe they have key splined shafting Quote Link to comment Share on other sites More sharing options...
Night Train Posted December 18, 2009 Author Share Posted December 18, 2009 Thank you Zoltan. Now it has a name it may be easier to find one 'off the shelf'. Checking with those dimensions seem to correlate. I will check out that site. Quote Link to comment Share on other sites More sharing options...
Night Train Posted December 22, 2009 Author Share Posted December 22, 2009 I still can't find a shaft of that size and spline off the shelf. That size tends to be 6 spline only. So I made one today. I turned a shaft to give the spline length, the major diameter and the minor diameter. I then scribbed the spline tips using the 60 tooth wheel on the lathe as an index. I used an angle grinder cutting disc to cut the splines. Then fettled with a file to fit. Job done. Quote Link to comment Share on other sites More sharing options...
zoltan Posted December 22, 2009 Share Posted December 22, 2009 Nice job. If I had that particular shaper cutter or hob I'd have been able to cut the splines for you at work. At you going to get it hardened? Quote Link to comment Share on other sites More sharing options...
Night Train Posted December 22, 2009 Author Share Posted December 22, 2009 Thanks, I was surprised that it worked so easily. I may heat treat it but after I have dealt with the other end of the shaft which is an unknown at the moment. However, it proves that I can make the splines sufficiently well to use. I have a chain sprocket that I might use that is a larger bore then the shaft I've made so I may make another, bigger, shaft. The first shaft is just mild steel but I have a high tensile bolt that will make a larger shaft for the sprocket and I will see how that goes. For what I have in mind (see my other thread in tools and fab) I could do with the extra reduction from the chain drive as opposed to direct drive. Just thought, this thread could really do with being in Tools and Fabrication now. Quote Link to comment Share on other sites More sharing options...
Ruuman Posted December 23, 2009 Share Posted December 23, 2009 nice work with the grinder, don't think I could have managed that Quote Link to comment Share on other sites More sharing options...
Night Train Posted December 23, 2009 Author Share Posted December 23, 2009 nice work with the grinder, don't think I could have managed that Thanks. Being a cabinet maker I found it was easier then fitting dovetails. I will have to make another now on a larger shaft. Quote Link to comment Share on other sites More sharing options...
Mark Posted December 23, 2009 Share Posted December 23, 2009 moved to tools and fab, as suggested. Mark Quote Link to comment Share on other sites More sharing options...
Phil Hancock Posted December 23, 2009 Share Posted December 23, 2009 An option for the spline cutting is to carefully grind a form tool and with it mounted at the correct hight sideways in the lathe toolpost with the spindle locked cut the splines by winding the lathe saddle back and forth as a shaper. Indexing as per what you already did. Quote Link to comment Share on other sites More sharing options...

Indexing as per what you already did. Yes, I tried that first but my lathe is a little too small to be sturdy enough to do that well. Having got one spline to a depth of 0.5mm on some scrap the tool post became loose and needed re setting again. I didn't fancy wearing out whatever moved by continuing. I did use that method to scribe the lines for the splines though. Quote Link to comment Share on other sites More sharing options...
Mwood37064 Posted April 4, 2021 Share Posted April 4, 2021 (edited) This is a club car golf cart motor.the splines must be only their brand specific.there are companies that make the female sleeve.but the only way to get what you need is by purchasing an input shaft for a club car president. If you want to trade that motor for something you could use easier, im shure i have something to work for you.
