Underground tunneling machine gear box structure

1, drive shaft (commonly known as the shaft): the role of the drive shaft is to transfer the kinetic energy of the wind wheel to the gear box gear pairs. FL1500 wind turbine gearbox biggest feature is placed inside the spindle gearbox. This design allows the fan more compact, reducing the size and weight of the nacelle, it is conducive to the protection of the spindle.

2, housing portion: box consists of three parts: the front body, the body and the rear body. Gearbox casing to withstand the reaction force from the air force and the gear wheel generated when the drive, and passes to force the main frame. Case part QT400 casting, this material has shock absorption and easy processing characteristics

3, gears: gearboxes growth mechanism - gears, using the two planets and a parallel shaft transmission. Planetary gear ratio mechanism may increase, reducing the volume of the gearbox.
