Gear box

The utility model discloses a gear box, which specifically comprises a box body, the first shaft and the second shaft are arranged in the box body in parallel; the transmission mechanism is connected with the first shaft and the second shaft and used for transmitting rotation of at least one of the first shaft and the second shaft to the other shaft; the tilting-pad thrust bearing is fixed on the box body, supports the first shaft and is used for limiting the axial displacement of the first shaft; and the first bearing is fixed on the box body, supports the second shaft and is used for limiting the axial displacement of the second shaft. In the scheme provided by the embodiment of the utility model, the first shaft is supported by the tilting-pad thrust bearing, and the tilting-pad thrust bearing not only bears axial thrust, but also provides proper rigidity and damping, so that the stability in the operation process is ensured, the problems of large vibration and bearing heating caused by overlarge axial dis
