What is the function of the gearbox between the drive turbine and the compressor? What’s the use of maintaining the rotational speed?
The function of the gearbox between the drive turbine and the compressor is to change speed.
It should be an acceleration effect, with the large and small gears changing speed.
Generally, the drive turbine itself has the capability to adjust its speed, so adding a gearbox isn’t necessary； However, it has indeed been seen that turbines drive air compressors through gearboxes (turbines of type H have dual intakes)
Variable speed, generally used to increase speed, right?
A gearbox is simply a transmission that serves to increase speed.
The gearbox is used for changing the speed – whether to increase it or decrease it – and this can be determined based on the parameters listed on the nameplate! On some nameplates, it is indicated directly whether it is a speed increase gearbox or a speed reduction gearbox.
Not even knowing what a gearbox is for – basically goodbye to the mechanical engineering field. :Q
The gearbox between the drive unit and the driven unit is primarily used for speed variation and power distribution~~ For example, if the speed of the motor is lower than that of the compressor, the motor can drive several high-speed shafts (for multi-stage compression)~~
It is a gearbox. Turbines and gas turbines can be made smaller in size at high speeds, which also improves their efficiency; a smaller size generally means a lower cost. Generally speaking, turbines and gas turbines are designed to operate at high speeds, with the speed then reduced before use, and this approach remains economical even after taking into account factors such as losses in mechanical efficiency due to gearboxes. This configuration is a method commonly used in the field of industrial drives.
Isn’t a gearbox just a transmission? . . .
