CHAPTER 29 Gearbox

Chapter Objectives

Identify the speed ratios for a given automobile gearbox.
Determine the number of gears on main, lay shaft, and idler gear shaft.
Work out the number of teeth on various gears to provide the desired speed ratios.
Determine the epicyclic gear trains with number of gears on sun, ring and planetary gears in each gear train.

29-1 INTRODUCTION

A gearbox is a device employed to provide variable speeds, depending upon the requirement of variable speed and torque, as the load on cutting tool changes (in a manufacturing machine), or load on gear wheels on road (in automobile), a device is employed to provide variable speeds. A discussion on gearboxes used in machine tools is beyond the scope of this book. ...
