Regarding gears nomenclature

chand_basha

Hi, 
     Could you please suggest me a material for all types of gears nomenclature. currently, I am following Theory of machines (RS Khurmi)  in that I have data only of spur gears, but I also need data of bevel, hypoid gears

I would recommend the standard ANSI/AGMA 1012-G05: Gear Nomenclature, Definition of Terms with Symbols. AGMA is the American Gear Manufacturers Association and is accredited by the American National Standards Institute to write all U.S. standards on gearing as well as for ISO.

"Gears and Gear Cutting" by Ivan Law is often recommended for those starting to learn about gears and it is only $13 if you are in the US:
