When we have to align a gear tooth form to a keyway, we usually cut the teeth first, then scribe the centreline of the tooth/gap down to the bore. From this we align for slotting/broaching.
Whilst simply "scribing" a line is not the most accurate method, it is good enought for our purposes...
Fluid Couplings do not usually howl. They throw off an awful lot of air when they are going at full speed, this air movement through a guard could be the source of the noise.
Also do you mean 60% speed or 60% load. If you mean load then I would examine any belts and bearings in the area.
If...
Gear coupings use a crowned and barrelled tooth form to allow flexing and accomodate shaft misalignment between machine shafts.
Check out Koppers (Kopflex) website at http://www.emerson-ept.com/eptroot/kopflex/default.asp for some technical articles about gear couplings.
They may be of help

A couple of years ago I looked at designing a holdback system for vertical ballscrews for use on the vetical axis of machine tools. Other projects superceeded it and it went no further.
Essentially there are very few options for ballscrew/linear motion braking/holding. The most popular system...
Catalogue ratings are based on an acceptable service life. Coupings are generally expected to outlast gearbox bearings, with the replacement of occasional wearing parts (e.g. rubber spiders in jaw couplings).
The short service life will give you considerably more options for both speed and...
There is no standard product available to do this duty.
Rexnord offer a metal disc type coupling from their BSD series that can cope with 55000rpm, but it is limited to about 1 degree angular misalignment. They are quite specialised but they may be able to help.
The only couplings used for...
Hirth Gears can be bought from Matrix. Their catalogue has some good info in, but I've mislaid my copy.
Their website is http://www.matrix-international.com
Look at the motion control bit.

We use a process called Blackfast, supplied by a company called Blackfast. I can't recall the chemistry, but it works well with steel and cast iron, although castings tend to drink it!
Try www.blackfast.com I think there are datasheets on the process there.
Hope this helps

Be very careful with hardened steel and welding. The heat affected zone from a weld will decrease/remove the hardness you have created.
Also consider the case depth you require, select a process that will give sufficient strength and hardness to the sub surface regions, rather than a...
I don't know of any specifications, but it may be worth buying a plastic tub/bottle and actually measuring it. At least it will give you an indication of what people do.
Alternatively you could try to contact the PPMA (process & packaging machinery association I think), they are a trade body...
Gear couplings bear the torque they transmit over a large number of teeth. The teeth in the outer are usually straight cut and are crowned & barrelled on the inner hub to allow flexing. The combination of multiaxial curves and minor elastic deformation of the teeth means that the load is...
