Specific implementation mode
The invention will be further described with example below in conjunction with the accompanying drawings：
As Figure 1-Figure 4, one kind of the invention " power generation " pumping-unit motor idle work output device, including differential gear
Take turns mechanism, freewheel clutch, holder and other drive connection parts.
The concrete structure of differential gear train is by internal gear-bracket bearing 15, and internal gear 11 is fixed in holder 1
Wall can relatively rotate.Internal gear 11 and 17 internal messing of planetary gear, planetary gear 17 and 7 external toothing of central gear, to form
Differential train.Wherein, by central gear-motor axle key 6, central gear 7 obtains power from motor shaft 3, and passes through planet
Planetary gear 17 and planetary gear rotation axis 20 are fixed together by gear fixing nut 18.And include in differential gear train
Three even circumferential arrangement planetary gear 17, planetary gear shaft 20.19 are held by tie-bar support board shaft, planetary gear is turned
The tie-bar support board shaft that moving axis 20 is fixed on tie-bar support plate 22 is held in mounting hole 22-1.Power output shaft 26 is solid by welding etc.
The modes such as fixed are fixed together with tie-bar support plate 22, and by power output shaft-bracket cover bearing 23, and power output shaft 26 is solid
It is scheduled on bracket cover 21, can relatively rotate.Spiral shell is fixed by power output belt wheel-power output axle key 24, power output belt wheel
Mother 25, the belt wheel 27 that outputs power is fixed on power output shaft 26, and as power output shaft 26 rotates, exports power.
The concrete structure of freewheel clutch is by freewheel clutch outer ring-bracket bearing 14, freewheel clutch outer ring 10
It is fixed on 1 inner wall of holder, can be relatively rotated.By freewheel clutch inner ring-motor axle key 4, freewheel clutch inner ring 5 is fixed on
On motor shaft 3, and rotated with motor shaft 3.Pumping unit belt wheel through-hole 2-1 is passed through by pumping unit belt wheel fixing screws 8, and is surmounted
Clutch outer threaded hole 10-1 screw-thread fits, pumping unit belt wheel 2 and freewheel clutch outer ring 10 are fixed together.Surmount from
28 both ends of clutch spring respectively connected freewheel clutch pawl 9 and freewheel clutch inner ring 5.
In addition to the matching relationship between above-mentioned part, pass through 4 uniformly distributed bracket cover fixing screws 16 of circumferencial direction
Across bracket cover through-hole 21-1, screw-thread fit is carried out with holder threaded hole 1-2, bracket cover 21 is fixed on holder 1.Holder 1
It is fixed by the bracket base mounting hole 1-1 being distributed in plane quadrangle.Pass through internal gear-freewheel clutch outer ring fixing bolt 13
The ring through hole 10-2 outside internal gear through-hole 11-1, freewheel clutch, will with internal gear-freewheel clutch outer ring fixing nut 12
It is locked, so that freewheel clutch outer ring 10 and internal gear 11 are fixed together.
The present invention operation principle be：
Under pumping unit normal operating conditions, motor shaft 3 drives freewheel clutch inner ring 5 to rotate, and drives overdrive clutch
Device pawl 9 rotates, so that the freewheel clutch outer ring 10 being engaged with freewheel clutch pawl 9 rotates, therefore and overdrive clutch
The connected belt wheel for oil pumping machine 2 in device outer ring 10 rotates, and drives pumping unit work.At the same time, motor shaft 3 drives central gear 7
Rotation, the freewheel clutch outer ring 10 of rotation drive internal gear 11 to rotate, by above-mentioned drive connection, be apparent from central gear 7 with
The rotating speed of internal gear 11 is identical, is known by the kinetic property of differential train, and planetary gear 17 is around planet rotary gear axis 20 at this time
Fixed-axis rotation is done, tie-bar support plate 22 and power output shaft 26 do not rotate, therefore power output belt wheel 27 is static, unpowered
Output.
In the case where pumping unit is in generating state, motor shaft 3 drives freewheel clutch inner ring 5 to rotate, but due to oil pumping
The effect of the sucker rod of machine, belt wheel for oil pumping machine 2 is by respective action power so that belt wheel for oil pumping machine 2 and connected with it super
More the rotating speed of clutch outer 10 is more than the rotating speed of freewheel clutch inner ring 5, therefore freewheel clutch outer ring 5 can squeeze overdrive clutch
Device pawl 9 so that freewheel clutch spring 28, which squeezes, to be shunk so that freewheel clutch pawl 9 is detached from freewheel clutch outer ring 5
Occlusion, causes the rotating speed of freewheel clutch inner ring 5 consistent with 3 rotating speed of motor shaft, and the rotating speed and pumping of freewheel clutch outer ring 10
2 rotating speed of oil machine belt pulley is consistent, and is higher than 3 rotating speed of motor shaft.At the same time, motor shaft 3 drives central gear 7 to rotate, and surmounts
Clutch outer 10 drives internal gear 11 to rotate, by foregoing description it is found that 11 rotating speed of internal gear turns higher than central gear 7
Speed.By the kinetic property of differential train it is found that planetary gear 17 had both done fixed-axis rotation around planet rotary gear axis 20 at this time,
It revolves round the sun around power output shaft 26, to drive planetary gear rotation axis 20, tie-bar support plate 22 and power output shaft 26 to occur to turn
It is dynamic, therefore the power output belt wheel 27 being connected with power output shaft 26 rotates, and motor idle work is exported.
