: : Hi,

: : Before you start designing a gear box, you should know the input and output requirements, such as,
: : - application, ex: machine tools
: : - input and No. of output shafts speeds, power and positions (speed ratio)
: : - power to be transmitted
: : - allowable space, etc.
: : Then you have to decide,
: : - type of gear pairs to be used
: : - No. of step-downs, or step-ups
: : - No. of levels of gears (widthwise)
: : - bearing sizes
: : - kinametics (gear train)
: : - lubrication provision
: : - accuracy required
: : - development of kinametics (gear train) showing cross-section views
: : - check for strengths, life etc
: : - check for assy./dis-assy. easiness etc.

: : You will have to consider everything depending on the application. It is difficult to list down the steps to be followed.
