Power takeoff assembly

Abstract

The invention relates to the technical field of transmission structures, in particular to a power takeoff assembly, a shell is provided with a gear supporting shaft and an output shaft in a penetrating mode, the gear supporting shaft is rotationally sleeved with a power takeoff driving gear, and the power takeoff driving gear is in gear meshing with a gearbox to obtain power; the periphery of the output shaft is movably sleeved with an output gear, and the output gear is connected with the power take-off driving gear in a meshed mode. A coupling mechanism is arranged on the output gear and is used for coupling and separating the output gear and the output shaft; output bearing covers are arranged at the positions, corresponding to the two ends of the output shaft, of the shell, supporting blocks are arranged on the sides, facing the interior of the shell, of the output bearing covers, and the supporting blocks make contact with the peripheral faces of bearings supporting the ends of the output shaft. When the output bearing cover is installed, the output bearing cover is positively installed or reversely installed, so that the axis position of the output shaft is located at different heights, under the two conditions, the output gear with the proper size and tooth shape is selected to be meshed with the power take-off driving gear, and the output shaft can output different torques.
