Description
Technical field
The present invention relates to a kind of pumping unit magnetic couple-gear drive, belong to pumping unit technical field.
Background technique
At present, oil field beam pumping unit adopts large and small belt pulley and the reducer group kind of drive to realize transmission of power and the deceleration of motor and crankshaft.The belt of this pumping unit easily skids, throws switch and weares and teares, and working life is short, there is security risk, needs to configure protective housing, and equipment occupation space is large.By the impact of crankshaft and motor shaft torque change rule, in subrange, when moment of torsion close to zero time, Belt Transmission Efficiency is very low.By the impact of small belt pulley cornerite, the jig frequency of pumping unit regulates will change belt pulley, wastes time and energy, inconvenient operation.At present, the jig frequency regulating method of pumping unit mainly contains the modes such as slowspeed machine, large speed ratio retarder and frequency variator, and cost is high, and efficiency is low, and frequency variator is to the bad adaptability of wild environment, and thus faults frequent, the life-span is short, affects the steady production of pumping unit.
Summary of the invention
The object of the present invention is to provide a kind of pumping unit magnetic couple-gear drive, to support the use with oil field beam pumping unit, improve mechanical efficiency.
Concrete technology contents of the present invention is as follows:
In the gear-box of this device, bottom is provided with input shaft, and middle part is provided with jack shaft, and top is provided with output shaft; The double helical pinion be located on input shaft engages two the herringbone gears broad in the middle be located on jack shaft; The herringbone intermediate speed pinion being located at herringbone gear sidepiece broad in the middle engages the herringbone gearwheel be located on output shaft, and output shaft two ends connect oil pumping machine crank; Input shaft connects the coupling be positioned at outside gear-box, air gap regulator, p-m rotor and magnetic conduction body disc simultaneously, and connects motor shaft by rotating shaft connector, is provided with air clearance between p-m rotor and magnetic conduction body disc.
Magnetic coupling in this device has overload protection function and allows larger installation error of centralization; can greatly simplify Installation and Debugging process; improve the reliability of whole device and the startup ability of motor; reduce shock and vibration, the step-less adjustment of output speed can be realized when motor speed is substantially constant, remote control and automatic control accuracy high; long service life; can various rugged environment be adapted to, compact structure, easy for installation.
