The load factor for obtaining pumping-unit motor declines to a great extent.In the prior art, general to be carried by maximum in order to guarantee the smooth starting of pumping unit
Lotus, that is, starting load match motor, so that load factor when existing pumping-unit motor works normally 30%~
Between 60%, there is " low load with strong power " phenomenon in normal work in pumping-unit motor, causes the waste of the energy.
Utility model content
The purpose of this utility model is to provide a kind of pumping-unit motors that energy utilization rate is high.
In order to achieve the above object, the technical solution adopted in the utility model are as follows: a kind of pumping-unit motor, including motor casing
Body is provided with the stator and rotor being fitted to each other in electric machine casing, and stator is fixedly connected with electric machine casing, and rotor is cylindrical,
Lumen and rotor arranged concentric and therewith composition synchronous rotation cooperation of the pipe axis through rotor, pipe axis empty set is on mandrel, pipe axis
End and the adjacent place of mandrel connected by gear transition.
Compared with prior art, there are following technical effects for the utility model: gear adjusts the revolving speed of mandrel
Section, not only can guarantee the smooth starting of pumping unit, but also can promote the load factor of motor, to promote the operational efficiency of motor.
Detailed description of the invention
Content expressed by each attached drawing of this specification and the label in figure are briefly described below:
Fig. 1 is the schematic diagram of the utility model.
In figure: 10. electric machine casings, 11. bearings one, 12. motor end-rack, 13. bearing three, 14. bearings four, 15. isolation ends
Lid, 20. stators, 30. rotors, 40. pipe axis, 50. mandrels, 60. gears, 70. gear box casings, 71. gearbox chambers,
72. bearing two, 73. gearbox covers.
Specific embodiment
With reference to the accompanying drawing 1, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
It describes in detail bright.
A kind of pumping-unit motor, including electric machine casing 10 are provided with the stator 20 being fitted to each other in electric machine casing 10 and turn
Son 30, stator 20 is fixedly connected with electric machine casing 10, and rotor 30 is cylindrical, and pipe axis 40 runs through the lumen and rotor of rotor 30
30 arranged concentrics simultaneously constitute synchronous rotation cooperation therewith, and 40 empty set of pipe axis is on mandrel 50, end and the mandrel 50 of pipe axis 40
Adjacent place is connected by 60 transition of gear.
Gear converts the high revolving speed of pipe axis, small torque to the slow-speed of revolution, the big torque of mandrel in electric motor starting,
Pumping unit is set smoothly to start；After pumping unit starting, gear promotes the revolving speed of mandrel again, makes its output torque and takes out
The operation torque of oil machine is consistent.In this way, just the starting of pumping unit can be realized using lower-powered motor, to promote motor
Efficiency, reduce the waste of the energy.
In the present embodiment, gear box casing 70, gear box casing 70 and motor casing are equipped on the outside of the end cap of electric machine casing 10
The end cap of 10 respective side of body is enclosed the gearbox chamber 71 for accommodating gear 60, and the shaft end of pipe axis 40 extends to gearbox
It is connected in chamber 71 with the input terminal of gear 60, mandrel 50 is arranged and become through electric machine casing 10, gear box casing 70
It is connected in fast case chamber 71 with the output end of gear 60.It, only need to be in electric machine casing in this way without redesigning electric machine structure
The reliable installation that gear box casing 70 is just able to achieve gear 60 is added in 10 outer end, thus guarantee pipe axis 40, mandrel 50 with
The reliability that gear 60 connects, and develop cheap with cost of manufacture.As shown in Figure 1, gear box casing 70 is set to motor casing
The right end of body 10, and it is enclosed gearbox chamber 71 with the right end cap of electric machine casing 10, gear 60 is mounted on gearbox
Chamber 71 is adjacent to one end of electric machine casing 10.
In the present embodiment, the specific cooperation of pipe axis 40 and mandrel 50 and mounting means are as follows: the both ends of mandrel 50 are by bearing
One 11,2 72 rotating support of bearing is mounted at the mounting hole of electric motor end cap 12 and gearbox cover 73 away from each other, pipe axis
40 are arranged with bearing 3 13 on the motor chamber side axle body of isolation end cap 15, and bearing 3 13 is mounted on isolation end cap 15
On, the other end of pipe axis 40 has the pipe end chamber 41 for accommodating bearing 4 14, and bearing 4 14 is set on mandrel 50.
That is, the bearing 1 and the bearing two on 73 inner wall of gearbox cover that are set on electric motor end cap 12
72 are fixedly mounted mandrels 50, and mandrel 50 is additionally provided with bearing 4 14 on the axle body of bearing 1, bearing 4 14 with set on being isolated
Pipe axis 40 is fixedly mounted in the bearing 3 13 of 15 motor chamber side of end cap, and inner ring circle face and the mandrel 50 of bearing 4 14 constitute quiet match
It closes, the inner wall composition stationary fit in outer ring circle face and pipe end chamber 41.
Bearing 3 13 is while realizing that pipe axis 40 is reliably installed in this way, moreover it is possible to guarantee the empty set of pipe axis 40 Yu mandrel 50
Cooperation.
What needs to be explained here is that isolation end cap 15 plays a part of that motor chamber and gearbox chamber is isolated.Pipe end chamber 41
Positioned at pipe axis 40 adjacent to one end of electric motor end cap 12.
