I want to start gear box design.Tell me the right way to approach it and what are the good books that i should refer.
There r a number of good books on gear design.
Gear design by Merchant.
Title not coming to mind - by Dudley.
the other references r just as good as given by the other person in reply to yr question. AGMA Standards r also there for various precision categories, likewise u have similar standards by UK.
hope u will find the list to kick off with yr project.
