I'm re posting this plea for help.
I'm still having a great deal of trouble in setting up the milling machine to cut the helical gears
I've come to realize that I had lost some of my mental comprehension to do calculations that were out line in the book "Theses On Milling "
by Cincinnati that was recommended to me by Johnoder.
The information I need to verified is the outside diameter of the gear blanks, the LEAD angle ( to set the transposition gears) and the milling machine table angle.
The metric gears are 2.5 MODULE
21 pinion tooth count
67 large gear tooth count
The large gear helix is 20 degrees for sure..
The man who needs the gears is a small family owned business.
The machine has been down for over 3 weeks.
Parts are not available here in the United States.
I told the customer I was having trouble setting the lead on my universal mill..
and I was seeking help to solve the problem..
He couldn't wait on me any longer and was desperate.
The customer found a machine shop in Tampa some 45 miles away who said that he could cut the gear (pinon)
but the machine shop didn't have the gear cutter or the proper material..
Trying to help the customer out ..I provided him with the gear cutter and the 4150 steel.
The gear was machined and he returned it to me for the heat treating .
He said that the machinist had cut it on his Bridgeport..
The pinion was cut straight on a 20 degree angle with no helix.!
Yesterday morning the customer and that machinist who cut the gear, tried to assemble the gear box and ran into trouble..as I suspected..
after 6 hour struggling ..they force the assembly together and "popped" the bearings apart.
This mixer has been down going on 4 weeks .
This man is going to loose his family business and his home ..
He's 60 years old..can you imagine starting over again at that age..
In these hard times I got to try to help this man out..
Johnoder had given me advice and I'm very much appreciated.
It's not my intention to abuse this site or badger any member
If I did this ..I apologize .
For me ..not being not able to concentrate a little frightening..I don't want my bride to know.
Again ,the information I need to verified is the outside diameter of the gear blanks, the LEAD angle ( to set the transposition gears) and the milling machine table angle.
I be willing to compensate anyone for their efforts if willing to help in this matter...
Please let me know..
