Description
Technical field
the utility model belongs to petroleum production machine power transfer unit technical field, relates to a kind of roller type communtation deceleration device.
Background technique
In prior art, pumping unit need to be converted to the circular movement of motor the straight reciprocating motion of sucker rod conventionally, in transfer process in order to reduce machine floor space, conventionally require the output of retarder to rotate the forward and reverse rotation changing for fixed frequency, thereby retarder has been proposed to the technical requirements of commutation, because hydraulic direction-changing mechanism floor space is larger, subordinate mechanism is more, therefore only under particular demands, just can use.
For the direction and rotating speed that changes retarder for the control that utilizes motor steering and rotating speed, the basic structure of the intelligent oil pumping machine that linear electric motor drive is by frame, head sheave, linear electric motor (stator, mover), equilibrium block, balancing band, damping spring, wire rope, Intelligent control cabinet, several major components such as variable-frequency power sources form, by the given stroke of Intelligent control cabinet, after the working systems such as jig frequency, start linear electric motor, but during work, motor is always in frequent starting, the working state stopping, larger impulsive load and electric current have shortened the working life of electrical apparatus element greatly, and then have influence on working efficiency, the reliability of mechanical commutation device is relatively high.
Utilize different mechanical devices and Der Grundsatz der Maschinen, can there is different schemes to solve communtation deceleration problem, the bench type drum oil pump that for example the gear pumping unit of the common development of Southwest Petroleum Institute, Henan Petroleum Exploration Bureau and Sichuan Mine Machine Plant is mechanical commutation.Its basic structure is in the transmission system between motor and cylinder, to increase the mechanical commutation device of a pin tooth planetary gears, make the existing deceleration of its speed reducer, have again periodic commutation effect, its output shaft characteristics of motion for just circling, counter circling hocket.Input shaft rotates jack shaft by gear transmission, and gear transmission passes to duplicate gear the rotation of jack shaft, duplicate gear empty set is in planet axis, the cycloidal gear teeth of duplicate gear and the engagement of the pin tooth on tumbler gear, insert in the sealing spill inside groove on people's tumbler gear at the two ends of planet axis, and one end empty set of swing arm is at the middle part of jack shaft, the other end is provided with planet axis, like this, planet axis can be rotated around jack shaft along with swing arm, when normal engagement, this rotation of spill inside groove restriction planet axis, swing arm can not be rotated.The now engagement of the pin tooth tinkling of pieces of jade of cycloidal gear and tumbler gear is ordinary transmission, it is stable drive ratio transmission, only when allowing planet axis, spill water jacket drive swing arm when jack shaft rotates, cycloid tooth crop rotation plane motion, the engagement of duplicate gear and tumbler gear pin tooth becomes outer gearing from interior engagement, thereby tumbler gear changes sense of rotation, makes chang-over speed reducing box output shaft also change sense of rotation thereupon, reaches the object of commutation.Do although it is so the function that can complete smoothly communtation deceleration, but our transmission ratios is subject to excessive restriction, the structure of driving mechanism is relatively sealed, and cannot expand transmission ratios, and Applicable scope is narrower.
The machine automatization commutation of load-belt pumping unit has adopted another kind of method, during work, motor drives the unidirectional forward of live axle in two reel automatic reversing apparatus by retarder and a pair of exposed gear, the swing clutch action of this live axle by plate in reversing arrangement or drive left reel drive plate to drive left reel forward by chain transmission, and by adhesive tape, right reel is reversed thereupon, or drive right reel forward, and by adhesive tape, left reel is reversed, thereby reach the object of the commutation of slowing down.But the swing that utilizes plectrum in the method realizes the control to turning function, and error is larger, and there is certain risk in the method reliability of reversing by adhesive tape.
The key of the normal work of drum type pumping unit is to have a long-term changement that can be stable under heavy load and moment of torsion, the unidirectional circular movement that motor is provided, after changement, export the periodically variable rotation of sense of rotation, thereby guaranteeing the normal work of pumping unit.Motor can change turning to of output shaft easily by controlling the direction of output voltage, subsidiary body is simple, delicate structure, but motor commutation impacts large, energy consumption is high, and system duty cycle is short, poor stability, generally, the peak output of motor is difficult to directly meet the power demand of pumping unit; Hydraulic pressure commutation can be born heavy shock loads, and commutation is stable, but equipment volume is huge, need to be equipped with independent a set of hydraulic pressure installation, subsidiary body is too fat to move, and cost is higher, and from existing device, long-term working stability is not good enough yet, within every 1 year, just need to carry out large repairs to equipment; And mechanical commutation has multiple choice in scheme, in function, should guarantee timely commutation, also want booster stability, can be because of overburdening voltage influence frequently working life, in function, can not carry too huge subsidiary body, increase equipment cost.
