Why gearbox is used in steam turbine?
Our high speed gearboxes are installed between steam turbine and electric generator. The function of the gearbox is to reduce the speed from extremely high turbine speed to the designated generator speed.
What is gear box in steam turbine?
Geared turbines are used for small-scale power plants of up to approximately 40 MW. A speed reduction gear is installed between the generator and turbine, allowing the turbine to be designed smaller while operating at high speeds.
What is the function of a reduction gearbox?
Equipment used to convert the output shaft revolutions of the main engine to those required to rotate the propeller. Gearboxes consist of meshing teeth on pinions and wheels which transfer power from a drive shaft to a driven shaft and reduce speed.
What is gear reduction?
A reduction gear is an arrangement by which an input speed can be lowered for a requirement of slower output speed, with same or more output torque. The high speed incoming motion from the wheel work is transmitted to the set of rotating gears, wherein the motion or torque is changed.
What is steam turbine engine?
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. A steam turbine connected to an electric generator is called a turbo generator.
What are the types of steam turbine?
The following types of steam turbines are available for private/thermal power generation plants.
- Small/Mid-sized Condensing Turbines.
- Extraction-condensing Turbines.
- Extraction Back-pressure Turbines.
- Mixed-pressure Turbines.
- Geared Turbines.
Does a reduction gearbox increase torque?
While in many applications gear reduction reduces speed and increases torque, in other applications gear reduction is used to increase speed and reduce torque. If the motor torque is 10 lb-in, the gearbox increases this torque by a factor of five to 50 lb-in (before subtracting out gearbox efficiency losses).
What is a 2 stage reduction gearbox?
Gearboxes are an important mechanical component that is widely used in wind turbines. The design and analysis of a two stage reduction gearbox. Its main function is to transmit the power generated by the wind wheel under the action of the wind to the generator and get the corresponding speed.
When large gear reductions are needed gears are used?
1. When large gear reductions are needed _________ gears are used. Explanation: Worm gears are used where large speed reductions are needed. The horizontal portion of the gear is called as a worm and the assembly of it with the gear is known as a worm gear.
What is the difference between steam engine and steam turbine?
While, steam engine and steam turbine use the large latent heat of vaporization of steam for the power, the main difference is the maximum revolution per minute of the power cycles that both could provide. In turbines, there are vanes designs with steels to give a rotary movement with the steam flow.
What is function of steam turbine?
The steam turbine generator is the primary power conversion component of the power plant. The function of the steam turbine generator is to convert the thermal energy of the steam from the steam generator to electrical energy.
