Described motor is vertical Y-series threephase asynchronous, and expansion type adapter sleeve is a kind of can be a kind of standard component the shaft coupling that the mode of two axle swellings connects together.
Described centrifugal non-maintaining type energy-saving clutch, comprise left active hub, middle active hub and right active hub, rotating shaft, driven disc, bearing, transmission meson, coupling, bearing gland, key and jump ring composition, it is characterized in that: left active hub (1) is connected with middle active hub (2), driven disc (13) is connected with rotating shaft (8) key (9), the two ends of key (9) are fixed with the first jump ring (10) and second (11), middle active hub (2) is connected with right active hub (3), bearing (4) is bumped into from one end of left active hub (1), bearing (5) is bumped into from one end of right active hub (3), coupling (6) is connected with left active hub (1), bearing gland (7) is connected with right active hub (3), middle active hub there is a plug, add at this or pour out transmission meson (12).
Described low noise gearbox, comprise casing, power shaft, gear teeth wheels, driven tooth wheels, output shaft, gearshift, it is characterized in that: power shaft is equipped with driving gear, a bite pressure bearing a bite plain bearing, gear teeth wheels four gears in one plane, driving gear is triangularly arranged at the change-speed gearing of middle three gears, three coaxial other ends of change-speed gearing respectively fill the identical driven gear of a diameter number of teeth, output shaft gear is identical with driven gear in its diameter number of teeth middle, these four gear composition driven gear groups, but they stir output shaft gear by gearshift and carry out speed change in three planes, three kinds of speed can be exported.Gear adopts helical gear, but oblique direction is contrary, and such as gear teeth wheels are oblique left, and the driven tooth wheels just oblique axial force in order to eliminate during transmission to the right, alleviates gear wear and reduce gear noise.Gearshift output shaft has a slip cap, and slip cap installs an output gear, and there is the slideway of a bearing inner sleeve slip cap one end, and on selector fork, two balls are set on this slideway, and shift fork is provided with linkage.
Described gear reduction unit is: with the driving gear on motor reel, meshing with the change-speed gearing on centrifugal non-maintaining type energy-saving clutch left active hub (1) power shaft, centrifugal non-maintaining type energy-saving clutch output shaft gear and speed reducer output shaft gear mesh complete mechanical soft start.
Operation principle
Motor of oil extractor is No Load Start when starting, and when rotating speed reaches 70%, centrifugal non-maintaining type energy-saving clutch starts there is output, adds that load realizes mechanical soft start gradually.Now because gearbox does not have neutral just to run with selected speed, run under motor carries out dynamic brake state during shelves oil pumper serious uneven overspeed descending and ensure sucker rod uniform descent, and the mechanical energy of decline is converted to electric energy directly feeds back to electrical network.Namely Self-healing power capacitor plays the effect of local compensation, can ensure that again motor is in the transfer process of electric motor state and engine condition, pumping voltage is no more than 5% of rated voltage, voltage and current waveform is just profound ripple all the time, make motor when rise and decline unbalance loading also can even running.Low noise gearbox has three to export gears, often changes belt pulley and just can change three output speed ratios, can adjusting stroke frequency easily.
The beneficial effects of the utility model are: 1. applying this device can reduce 50% ~ 70% motor of oil extractor power, supply transformer can reduce over half, diameter of wire can attenuate and improve power factor, integrated power-saving rate is high, 2. this plant running does not steadily impact the useful life that can extend oil pumper, and 3. this apparatus structure simple-to-maintain is convenient.
