BASE DIAMETER D is the diameter of the base cylinder from which the involute portion of a tooth profile is generated BACKLASH B is the amount by which the width of a tooth space exceeds the thickness of the engaging tooth on the pitch circles As ac 1 INTRODUCTION Gear is one of the important machine tool elements which is an integral and inevitable part of power transmission system A gear is a round blank having teeth along its periphery Gears are used to transfer powe r or torque from prime mo Introduction. The bevel gears are used to make a more compact epicyclic system and they permit a very high speed reduction with few gears.. The useful application of the epicyclic gear train with bevel gears is found in Humpage’s speed reduction gear and differential gear of an automobile.. Gear Trains. Chain-Sprocket systems.

Power transmission is the movement of energy from its place of generation to a location where it is applied to performing useful work. Gear system or box is a transmission system of power which is used in all type of vehicles. Gear is a speed and torque changing device used between the engine and the driving wheels. It is a simple machine used to generate more speed or power or send the power of machine in another direction. Gears. A gear is a simple machine like a lever. The larger the diameter of the gear the longer the lever. What are Gears used for?. Ensure positive motion. Reverse the direction of rotation. Increase or decrease the speed of rotation.
