Abstract

The invention relates to a motor for a tower-type pumping unit and a tower-type pumping unit thereof. The motor of the invention comprises an inner planet gear box and a motor combination set, a bearing, a gear stand, a gear stand, a gearwheel and pinions, a shaft, a bearing, an outer rotor motor, keys, an outer rotor motor stator, a motor outer rotor and a gear, wherein the gears carry out the transmission in a superposition way; the motor outer rotor is arranged outside the outer rotor motor; the gear is nested in the motor outer rotor; a plurality of pinions are arranged between the outer edge of the gear and the inner edge of the gearwheel to form an inner planet reducing mechanism; the pinions mesh with the gear and the gearwheel; the pinions are fixed with the shaft; when the outer rotor motor rotates, the pinions rotate around the central axis of the bearing together with the shaft; and heat generated by the operation of the outer rotor motor heats the inner planet gear box, so that the gear oil can not solidify. The invention has the advantage of little equipment maintenance and is especially suitable for oil extraction in cold areas.

Description

technical field [0001] The invention relates to a motor for a tower pumping unit and the tower pumping unit thereof. The motor is a power machine combined with an inner planetary gearbox and a motor, and the tower pumping unit is used for oil exploitation. Background technique [0002] At present, in the driving machinery used in oil development in various countries, the gearbox in it exists as a separate device. Since the gears need to be lubricated with gear oil during operation to increase the efficiency of the gears and prolong the service life of the gears, when the ambient temperature When it is too low, the gear lubricating oil is easy to solidify and become solid, and the protective and lubricating effect of the solidified lubricating oil on the gears is greatly reduced. At the same time, maintenance is required, which increases the maintenance cost. Some maintenance work cannot be performed due to the limited maintenance conditions. , so it is urgent to invent a dri...
