Title: Gear cutting machines
Post by: Bernd on October 30, 2009, 04:59:53 PM

There has been much talk on the forums over the past of gear cutting. Having worked in that industry I thought I share some of the "old" time gear cutting machines I worked on. These are U-tube videos that I came across today. Never even knew they existed until today.


This is not a Gleason machine. Bog's might be interested in this one since he wanted to cut an internal gear. This machine will cut internal teeth. The cutter would be the same. I believe they are "forming" the tooth profile.

This machine is a 641 Gear Generator. I helped by working on the prototype. It can cut both "gears" and "pinions"

This is the gear cutter that the 641 replaced.

This is the samllest gear cutting machine Gleason made. It uses two cutters to cut a straight bevel gear. These machines were orginally designed for the sewing machine industry. The machine takes up a space approximatley 3' X 3' and is about 5' tall. There is also a spiral gear generator this size.

This is the previous machines bigger brother.

And this is how they do it today.

So next time you ask. How gears are made take a quick look on U-Tube. Videos explain much better than words can.

Very interesting indeed Bernd.

As you stated, the first one is almost the same method as I will be using to cut the internal gears, but my method won't require all that complicated machinery.

Mine will use brute force and ignorance.

If you run short of ignorance, just lemme know....LOL

Well it'll at least give the people that have never seen gears cut an idea of just how they are made.

Your method may be brute force, but so is the machines. The machine just has a higher horse power motor on it that's all. Ignorance? Where? You? Naw I don't think so. Just doing what you need to do with what you got. I'd say that would be "Brilliance".  :thumbup:

BTW, what is your horse power rating Bog's?  :lol:

If I go with the suggestion from John Stevenson and power from the quill, then 2 HP.

If I use my own brawn, just enough grunt to get the job done.

That's all that counts then. Of course you'll have a rest every so often for a coffee right? Need to refuel for the next couple of strokes.
