Abstract
A speed reducing device of single crank multiple range flexible beam-pumping unit, is mainly to solve the problems that the prior decelerator of the energy consumption of the pumping unit is high, the unit size and the deadweight is big, and the initial investment is too much. The utility model is characterized in that: a crank axis (2) connects with the output axis of a pin cycloidal reducer (3) which connects with a motor. The utility model has the characteristics of that the energy consumption is low, the unit size and the deadweight are small, and the initial investment is less, etc.
Description
Technical field:
The utility model relates to the used speed reducer of pumping unit, especially single-crank multiple-stroke flexible type pumping unit speed reducer in the oil recovery field, oil field.
Background technique:
Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.At present, be used to pumping unit into worker's lifting based on beam pumping unit, be divided into conventional type beam pumping unit, prefix type beam pumping unit, out-phase type beam pumping unit and two horse head type beam pumping unit according to the difference of the structure of the crank quadratic crank mechanism of horse head.The speed reducer power consumption of the pumping unit of this structural type is high, and machine packet size and deadweight are all very big, and one-time investment is more, is unfavorable for applying.
The model utility content:
In order to solve existing pumping unit speed reducer energy consumption height, machine packet size and deadweight are all very big, the problem that one-time investment is more, the utility model provides a kind of single-crank multiple-stroke flexible type pumping unit speed reducer, it is low that this single-crank multiple-stroke flexible type pumping unit speed reducer has energy consumption, machine packet size and deadweight are all little, the characteristics that one-time investment is less.
The technical solution of the utility model is: this single-crank multiple-stroke flexible type pumping unit speed reducer comprises motor, crankshaft and retarder, and crankshaft links to each other with pin pendulum reducer output shaft, and pin pendulum reducer input shaft links to each other with motor.
The utlity model has following beneficial effect: this single-crank multiple-stroke flexible type pumping unit speed reducer is owing to take such scheme, because of pin pendulum retarder velocity ratio big, so utilize the motor of smaller power just can obtain bigger output torque, pin pendulum retarder directly is connected with crankshaft with motor, improved transmission efficiency, machine packet size and deadweight are all little, compact structure, one-time investment is less, so whole machine packet size of this pumping unit and deadweight reduce, energy consumption is low, and one-time investment also reduces, and helps applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-motor among the figure, 2-crankshaft, 3-retarder.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this single-crank multiple-stroke flexible type pumping unit speed reducer comprises motor 1, crankshaft 2 and retarder 3, and crankshaft 2 links to each other with pin pendulum retarder 3 output shafts 4, and pin pendulum retarder 3 input shafts link to each other with motor.Because of pin pendulum retarder velocity ratio big, so utilize the motor of smaller power just can obtain bigger output torque, pin pendulum retarder directly is connected with crankshaft with motor, has improved transmission efficiency, and machine packet size and deadweight all reduce, make compact structure, one-time investment is less, so this pumping unit has whole machine packet size and deadweight reduces characteristic of low energy consumption, and one-time investment also reduces, and helps applying.
