Vertical planetary gearbox loading test device

The utility model relates to a vertical planetary gearbox loading test device which comprises a gearbox to be tested and a load motor which is a horizontal motor, and further comprises a loading gearbox. The loading gear box is used for converting the torque direction of the output shaft of the gear box to be tested from the vertical direction to the horizontal direction and then transmitting the torque direction to the input shaft of the load motor, so that the gear box to be tested, the loading gear box and the load motor are arranged in an L shape. In order to solve the problems of high cost and high potential safety hazard of the arrangement of the device, the utility model reduces the height of the loading test device, reduces the test cost and reduces the potential safety hazard, and meanwhile, through the arrangement of the sealing cover and the sealing ring, the oil splashing of the gearbox to be tested in the test process is avoided, and the environment-friendly effect is achieved; the load motor rot
