Today gears are almost used in every industry. It is the most common device for transmitting power in mechanical engineering. Gears are an important component of small but complicated machines like clock to large kiln and mill drive system. The gears form an essential part in running of various machines and automobile.
There are variety of gears available that are used in different industries according to the specific requirements. These gears can be classified under automotive gears, mining gears, marine gears, wind turbines, bicycle gears, mill heads, instrumentation gears, conveyor system and more.
The basic function of the gear is to alter the rotational speed, power or torque and direction between input and output shaft. Torque is the measure of force required to produce torsion and rotation about an axis. When a large gear drive is coupled with a smaller gear drive, the torque is reduced and the speed of the rotation is increased. Different arrangement of the gears can also be used for enhancement of positioning system.
Automotive Industry require automotive gears for high torque capacity and to convert mechanical energy smoothly and noiselessly. The type of automotive gears used are Manual transmission, Semi automatic transmission and Automatic transmission.
Marine uses gears in various vessels like fast ferry boats, luxury yachts, frigates and work boats etc. These marine gears are usually more powerful and they meet critical applications. Types of marine gears used are Planetary Gears, Worm Reduction Gears and Helical Gears.
Agricultural Gears are widely used in the agro industry. Agricultural Automotive Gears are used in processes like tilling, seeding, ploughing, irrigation, pest and insect control etc. The agriculture vehicle, tractor also make use of these agricultural gears in its mechanism. Usually Spur Gears, Helical Gears, Worm Gears and Sprockets are used.
Few of the gears are used for mill heads in cement plants, sugar mills, sag mills, tube mills, coal mills, sponge iron plants, gold mine sand many more. These gears are Girth Gears, Spur Gears, Face Gears, Spiral Bevel Gears and Helical Gears.
Different types of gears are used in mining industry to keep the machines run efficiently by power transmission in both above and underground operations. Types of gearboxes used are Bevel Gear , Helical Gear, Right Angle Gear, Parallel Shaft Gear, Planetary Gear and Worm Gear.
Power Station make use of high quality and high precision gears for the use in power generation equipment and machines. They are used for for high speed application. The gears that are usually used are Parallel Shaft Gears and Planetary Gears.
