In every process of power generation and power transmission, gear power transmission equipments have been used for a long period of time. Gear equipments support all different aspects of the power generation process. Gear peripherals are used in different processes of power generation, like in the gas turbine electric power generation, air pre-heater fan drives, coal-power electrical plants any in many others. In some operators, which are used for manufacturing electricity, rugged bevel gears are used. These bevel gears are used in seating and unseating the high pressure gates. These gears are also used in the global valves all around the world. To ensure that all the torque enter into the turbine valves, the stem on the MT operator is joined in the drive sleeves. The stem consists bevel gears and ductile iron.

Turbo Gears
Turbo gears having high performance, gear units for rotor turning and couplings are also used for high speed and heavy industries, like electricity generation industry. The turbo gear units are used for transmitting electricity up to 80 MW. Rotational speed of these gears are approx. 80,000 rpm.

Parallel Shaft Gears
Another type of gears are used in the electricity industry. These are called as Parallel shaft gears. These gears are used in this industry, because these gears can operate continuously at a very high speed. Wheel sets, which are used in electricity industry, may have helical or double helical gears with or without thrust cone. Another version of parallel shaft gears, turbojet parallel shaft gears are used in those electricity generation devices, which require reliability. These gears can be operated at a very high speed with high power density. Both vertical and horizontal arrangements are adaptable for these gears. On the free shaft ends of the turbo parallel gears, additional lubrication oil pumps and rotor turning gears can be placed.

Multi-shaft Internal Gears
Integrally geared compressions are used in the electric power industry. For these compressions, multi-shaft internal gears are used. These gears are also applied, where intermediate cooling of the medium is used and integrating different power machines is required in the electricity power industry. The gears are used in expansion turbines, electric motor and steam/gas turbines.

Planetary Gears
Planetary gears are used in different applications of power industry. The most common uses of the planetary gears are in high speed turbo system, bowlers and pumps. All these devices are used in the electric power generation.
