Embodiment Construction
[0016] like Figure 1-3 As shown, in a preferred example of a four-geared ring parallel pumping unit according to the present invention, it includes a frame 30, an internal geared ring parallel slider system, a planetary gear and a tie rod system, a motor and a transmission system, an electromagnetic Brake system. The inner gear ring parallel slider system, the motor and the transmission system are installed on the frame 30, the planetary gear and tie rod system are arranged on the inner gear ring parallel slider system, and the electromagnetic brake system is arranged on the motor and the transmission system.
[0017] Specifically, the internal gear ring parallel slider system is provided with an inner gear parallel slider 16, and two parallel inner gear groups are installed on the inner gear parallel slider 16, and each inner gear group consists of two symmetrical The inner gear ring is composed of 7. The motor and transmission system are made up of motor 26, speed reducer...

The invention discloses a pumping unit with four ring gears connecting in parallel. The pumping unit is composed of a rack system, an inner ring gear parallel sliding block system, a planet wheel and tie bar system, a motor and transmission system and an electromagnetic brake system; the pumping unit is characterized in that the inner ring gear parallel sliding block system, the motor and transmission system are installed on the rack system, the planet wheel and tie bar system is arranged on the inner ring gear parallel sliding block system, and the electromagnetic brake system is arranged on the motor and transmission system. A four-parallel-ring-gear sliding block device used for the pumping unit with the four ring gears connecting in parallel is provided, by means of two sets of symmetrical rocking beam devices, the capsizing moment produced by a single set of the rocking beam devices is counteracted, and the direction of the resultant force suffered by the inner ring gear parallel sliding block system is located on the vertical geometrical center line. The pumping unit has the advantages that the reversing is stable, the heavy load is obtained, the efficiency is high, and the pumping unit is safe and reliable.
Description
technical field [0001] The invention relates to an oil field mechanical pumping equipment, in particular to a four-tooth ring parallel pumping unit. Background technique [0002] At present, the beam pumping unit widely used at home and abroad is still the beam pumping unit. The traditional beam pumping unit consumes a lot of energy, has low efficiency, and the stroke is increasingly difficult to meet the market demand for long strokes. The patent number is: CN95241603.4 planetary gear ring type non-swimming beam pumping unit and the patent number is: 200920019023.1 long ring rack pumping unit. The sucker rod reciprocates up and down to realize the oil pumping process. This method produces an overturning moment on the support rod that fixes the pinion, which easily deforms the pumping unit on the long stroke and high frame, and then causes the gear meshing and transmission system to be damaged. Contents of the invention [0003] The technical problem to be solved by the ...
