Gleason bevel gear planer #3

This is the final video of the vintage Gleason automatic bevel gear planer.This video shows the arm following the upper side of tooth templet or form as it cuts the tooth. There are 25 sets of forms for both 14.5 and 20 degree presure angle. The proper templet is determined by the pitch angle of the gear.
Gear is finished by completing the top side, Change to bottom side cutter and templet and cut to size.
This machine predates 1926 I am told.

How long takes it , to make a bevel gear like this one ?

[rumelyeoilpull]

@Udolahr I do not remember on this gear for sure, but it probably had around 12 hours of machine run time in it. I do not run this machine as fast on the tool speed as the previous owner says he did.

It automatically indexes so I set it up and let it run until the micro switch on the spindle shuts it off. Then I check it and reset it.

[Udolahr]

thank you very much for all the info !

How is the feed for the turning table ?Is it a constant feed with gears , or with a ratche every time the cutter has a stroke ?

[rumelyeoilpull]

@Udolahr Feed of the tool in and tool cutter speed are controlled by change gears. Feed in for depth of cut is also on a cam so it retracts faster than the feed in. No ratchets.

Indexing is also by change gears.

[Udolahr]

OK, so you have a cutter for the top radius ,and a mirrored cutter for the bottom radius ?

A templet for top lifting the roller up , and a templet for bottom with the same radius to let the roller down.

Do you need differend templets ( differend radius )if a gear has 15 teeht or 60

teeht ? And a templet for every modul ?

@Udolahr You got it! Cutter and templet for top and bottom are "mirror" images. The templet is actually an invoulute curve. The radius ground on the end of the tool gives the radius at the bottom of the tooth.

I have 25 14.5 degree pressure angle templets and 25 20 degree templets.

The templet you use is determined by the pitch cone angle. This depends on the number of teeth of both gears. Each templet will cut a small range of pitch cone angles.

I think I need a machine like this one ! In North Carolina is a Gleason 37 for sale , it looks like yours . But maybe the transport to Germany is to expensive .

The feed for the depth is made with a cam . So from the beginning of the cut to the end of the cut , the cutter moves a little sideways ? I hope , if you cut a gear next time , you make a video , not only from the cutting it self . Just show how the machine funktion .

@Udolahr As I stated in the information tab above, a top and bottom templet and cutter are used to finish the teeth. I run the top side first until It cleans up at profile.

Put bottom side tool and templet in and run until gear tooth is to size at pitch line on the OD.

[Udolahr]

the cutter cuts only one side , how can you cut the other side ? Can you show a video how to finish a gear ? And maybe a little more about the machine , how it funktion ? I never did see a machine like this one bevor .

@Udolahr It still makes a gear now and then. It is more suited to onesy twosy type jobs than production. The old gal doesn't owe me any money as she has paid for herself.

It is retired from from job shop use as I have a day job [electrician} and can use it when I want to take in a job for it.
