Power takeoff at rear end of engine

The utility model relates to a power takeoff at the rear end of an engine. The power takeoff comprises a power takeoff input end, a power takeoff output end and a power takeoff shell, wherein a bearing cavity for accommodating a bearing is formed in the power takeoff shell; the power takeoff shell can be embedded into a flywheel shell and is detachably connected with the flywheel shell; and the part of the power takeoff shell, which is embedded into the flywheel shell, is provided with a lubricating oil channel communicated with the bearing cavity. The power takeoff shell can be embedded into the flywheel shell and is detachably connected with the flywheel shell, so that the problem that the conventional power takeoff at the rear end of the engine is difficult to assemble and disassemble is effectively solved; furthermore, the part of the power takeoff shell, which is embedded into the flywheel shell, is provided with a lubricating oil channel communicated with the bearing cavity, so that the inner part of the power takeoff can be directly lubricated; and compared with the conventional method for lubricating the inner bearing of the power takeoff through an external oil channel, the power takeoff has the advantages that the assembly space in the engine is saved, and the production cost is reduced.
