Gear Menufacturing Machines

Gear Menufacturing Machines - A gear is a toothed wheel which when meshed with other gears transmits motion from one part of mechanism to another. Gears transmit power and/or rotary motion from one shaft to another. Positive transmission of power is accomplished by teeth on the circumference of the gear. There is no slippage as is with friction and belt drives. Exact speed ratios ale possible with gear drive.

Gears form an indispensable element in the construction of machine tools and other machines. Gears are used on nearly all types of machines ranging from wrist watches and egg beaters to machine tools, automobiles, farm equipment and heavy machinery. Gears may be only a few mm or 7600 mm in diameter, from 0.25 to 1800 mm wide.

With the ever growing demand for higher speeds, quieter running of the machines, the manufacture of gears has become an increasingly refined and specialized art. Several companies make only gears and similar items.

Many small and medium sized concerns buy most of their gears from these companies because they actually get better quality at a lower price than if they make gears themselves. The present chapter will discuss various commercial methods of manufacturing gears.
