Hi,
Has anyone got any advice for generating fellows stub teeth (6/8, 8/10) teeth using IV gear generator? Is anyone out there using any other software which can be recommended?
thanks,
Nick
Inventor will generate the involute profile for you. I have experimented with it, but I am just not comfortable with it. I don't understand the various factors and I cant find information on them that I can make sense of. If I have to generate the profile, I dont use Inventor to do it.
We cut alot of large gear teeth here and I have to develop the involute profile for each one. We give this profile to a tooling supplier and they produce a cutter based on this profile. The gears we cut are for various standards and can have different backlash and/or tip relief (parabolic). The software I use is GearTeq (by Camnetics). They also have a GearTrax AI that will generate the involute profile, but with the GearTeq you can create a free form gear. With either of these, the involute profile can be brought into Inventor.
Let me know if you need help with these.
Nick,
I'm not really fimilar with this gear so I looked it up in the Mach Handbook. It says its an "infrequently" used gear. They actually say to reference 18th edition or earlier for the tooth dimensions. I have the 25th ed.
I tried to develop a Fellows Stub in GearTeq. I can get a like 8/8 or 10/10, but not 6/8 or 8/10. Here is a video of the gears that I made just for a test. During the video, on the left hand side, I scrool thru the data for the gear so you can see what information GearTeq will give you. You can save this out to a .xls spreadsheet.
