The tutorial should explain how to generate gear profiles using excel.
First Download and open the Excel spreadsheet 'Gear Calculator' attached.
You can find all tutorial graphics in the RAR file.
You can see an example here:
15 Tooth & 18 Tooth gears meshing
15 Tooth & 18 Tooth gears meshing
You could also use the dxf builder at www.me-bac.com for normal spur gear and also for corrected gear.
Hi, do you have an excel for a planetary ring (annulus)?
Hi graphiX unfortunately I do not have calculations for this.
Hey, can I do this using Inventor?
If yes, please help me, I really need this.
