The invention provides a power takeoff. The power takeoff comprises a shell, a driving gear, a transition gear and an output gear, wherein the driving gear, the transition gear and the output gear areengaged. The power takeoff further comprises a transition axle. The transition axle is sleeved with bearings and a bearing end cover. The transition gear is sleeved with the bearings. A groove is formed on the shell, and an oil storage cavity is formed between the groove and the bearing end cover. A lubricating channel communicating with the oil storage cavity is formed on the transition axle. The number of the bearings is two. A check ring fixed to the transition gear is arranged between the two bearings. An opening at the end, facing the bearings, of the lubricating channel is arranged upwards and located between the two bearings. The liquid level of lubricating oil in the oil storage cavity is higher than the horizontal position of the upper end point of the transition axle. Accordingto the power takeoff, the bearings are lubricated through the pressure difference between the lubricating channel and the oil storage cavity, the supply amount of the lubricating oil is effectively ensured, the lubricating effect is relative good, the structure and the process are simple, the machining difficulty is low, and the lubricating is relatively good.
