Abstract
The utility model discloses a novel pumping unit with a torque transmission system and a load system separated. The novel pumping unit with the torque transmission system and the load system separated comprises a frame, a base and a balancing box. A permanent magnet synchronous motor is adopted and is fixed on the frame. A belt wheel is installed on a main shaft of the permanent magnet synchronous motor, a big belt wheel and a friction-belt-bearing wheel are fixed on a friction-belt-bearing wheel axle, two ends of the friction-belt-bearing wheel axle are respectively fixed on an axle-fixing base, and the big belt wheel and the small belt wheel are connected through a transmission belt. The permanent magnet synchronous motor is fixed on a working platform at the top end of the frame. Due to the adoption of a structure with a drive system and a bearing system (an oil rod-balancing box system) separated, the motor transmits torques but does not bear quality of any load-bearing system, and therefore the size of the motor is not too large, the main shaft of the motor and a bearing of the motor can work under very small stressed work conditions, service life of the motor is prolonged, and maintenance cost is reduced.
Description
Technical field
The utility model relates to the oil pumper that a kind of oil exploitation is used, particularly the new pumping unit that separates with load system of a kind of moment of torsion transmission system.
Background technology
The transmission system of tradition beam pumping unit is from the power end to the suspension point, and is general through slowing down, commutating two stages.Rotating speed of motor is 750,1500r/min, realize up and down reciprocatingly 2～12 times/min and drive load movement, motor must adopt deceleration device that the motion mode of high speed, low moment of torsion is converted to the motion mode of low speed, high pulling torque through slowing down, and the speed reducing ratio of reductor is 375,750.Motor by commutation can realize Rotation With Changing to, as long as the deceleration function satisfies positive and negative motion, directly drive oil well pump with speed reducer output shaft, can realize oil recovery process, but reductor will be realized positive and negative normal rotation, the scraper plate lubrication problem that splashes of the bearing of slow-speed shaft, jackshaft can't be lubricated when reductor commutates reliably, the positive and negative rotation of reducer gear in addition, gear engagement commutation is frequent, tooth root fatigue causes gear to damage, many manufacturers all attempt using this mechanism, but all can't pass this pass of reductor life-span.Structurally traditional oil pumper adopts the turbine and worm motor as driving mechanism, motor directly is fixed on the carrying friction belt wheel, motor plays carrying and the effect that drives, as shown in Figure 1, be existing structure motion simplified schematic diagram, 1 ' is the turbine and worm motor, its rotating spindle is same axis with carrying friction belt shaft 5 ', the rotation of turbine and worm motor 1 ' drives the rotation of the carrying friction belt wheel 6 ' that is fixed on its main shaft, the rotation of carrying friction belt wheel 6 ' can drive the motion around thereon carrying friction belt 7 ', carrying friction belt 7 ' is walked around directive wheel 9 ' again, makes that directive wheel 9 ' also can be along with rotation.And carrying friction belt 7 ' two ends are respectively tandem-driving bogie suspension point 10 ' and beam hanger suspension point 11 ', the motion of carrying friction belt 7 ' makes tandem-driving bogie and beam hanger move up and down, and both direction of motion is opposite, just because of the motion up and down of beam hanger, thereby reaches the purpose of oil pumping.
The shortcoming of this cover mechanism: the main shaft of turbine and worm motor 1 ' is same axis with carrying friction belt shaft 5 ', other has a guide wheel shaft 8 ', this is overlapped the pulling force that two external force of mechanism is tandem-driving bogie deadweight and beam hanger side, and these two power have all acted on these two above the axle, wherein the main shaft of turbine and worm motor 1 ' is same axis with carrying friction belt shaft 5 ', this root axle one end is fixed on the frame by bearing support 12 ', the other end is to be connected on the turbine and worm motor 1 ', it is the effect that turbine and worm motor 1 ' has directly born external force, and these two external force are very big, this causes the 1 ' life-span of turbine and worm motor extremely short concerning turbine and worm motor 1 ' stressing conditions extreme difference.The moment of torsion of turbine and worm motor is the actual moment of torsion that offers whole system, does not amplify through reducing gear, so moment of torsion condition of work very severe concerning main shaft and bearing greatly makes equipment perishable, the energy consumption height.
The utility model content
The purpose of this utility model is to design the new pumping unit that a kind of moment of torsion transmission system is separated with load system, it makes the load system (beam hanger-tandem-driving bogie system) on the oil pumper separate with the drive motors system, reduction is to the requirement of motor performance, prolongs motor application life, convenient later maintenance.
The following structure of this novel employing realizes above-mentioned purpose, the new pumping unit that a kind of moment of torsion transmission system is separated with load system, comprise frame, pedestal, tandem-driving bogie, motor adopts permagnetic synchronous motor, permagnetic synchronous motor is fixed on the frame, on its main shaft small pulley is installed, and big belt wheel and carrying friction belt wheel are fixed on the carrying friction belt shaft, friction belt shaft two ends are separately fixed on the holder, and big belt wheel is connected by driving belt with small pulley.
Permagnetic synchronous motor is fixed on the working platform of frame top.
Big belt wheel compares less than 3.55 with the diameter of small pulley.
The utility model is owing to adopt drive system and bearing system (beam hanger-tandem-driving bogie system) separated structures, make only carry-over moment and do not bear the quality of any load-carrying system of motor, this just makes the structure of motor be unlikely to too huge, and its main shaft and bearing also can be worked under stressed very little operating mode, make the life-span prolong greatly, reduce maintenance cost.
Because sleeve mechanism has three axles, external force is the deadweight of tandem-driving bogie and the pulling force of beam hanger side concerning mechanism, and these two power all be applied to carrying friction belt shaft (with big belt wheel be same axis) and guide wheel shaft on, main shaft on the permagnetic synchronous motor and this two power are irrelevant, permagnetic synchronous motor just drives the rotation of big belt wheel through the transmission of driving belt by the rotation of small pulley, permagnetic synchronous motor has only provided the motion that moment of torsion drives sleeve mechanism, and needn't bear too big external force effect, improve its force-bearing situation thereby reach, prolong working life.
Adopt this novel slowing-down structure, load system (beam hanger-tandem-driving bogie system) separates with the drive motors system, make motor only transmit moment of torsion and do not bear the mass of system of beam hanger-tandem-driving bogie, use the transmission system of this structure can improve moment of torsion (3.5 times), the stressed of electric machine main shaft and bearing reduced greatly, thereby in the application life of improving the condition of work of motor and significantly improving motor, later maintenance is easy to adjust.
This kind oil pumper possesses---transmit that moment of torsion is big, the motor long service life, safeguard easy to adjust.
Moment of torsion by this scalable traction machine of cover mechanism makes that the difference of two external force (pulling force of the deadweight of tandem-driving bogie and beam hanger side) can be bigger, can adapt to different oil well conditions.
