How can I design a gear train to meet specific torque and RPM requirements?

[QUOTE="jrmichler, post: 6453816, member: 638574"] Your sketch would work. There is a lot more to designing a gear reducer than just calculating numbers of gear teeth. Gear pitch diameters, gear tooth size, gear tooth form, shaft sizing, bearing sizing, housing design, lubrication, and much more all need to be calculated. A good book to read is Dudley's Handbook of Practical Gear Design: [URL]https://www.amazon.com/dp/1498753108/?tag=pfamazon01-20[/URL]. If you read this book, you will understand why most engineers avoid designing their own gears if at all possible. Are you sure that you need a gear drive? There are also synchronous belt drives available that work very well. One example is Gates Poly Chain GT belt drives. See this link to their catalog: [URL]https://www.gates.com/content/dam/gates/home/resources/resource-library/catalogs/old-pc_carbon_manual17595_2011.pdf[/URL]. They have the components to make a 7:1 reduction drive in a single stage. If you need gears, the preferred method is to buy a gear reducer. There are many manufacturers of many different styles of gear reducers. A search will find them. Or is this a homework problem? If so, it needs to be moved to the Homework Help - Engineering section.
