A1, described δ
A1It is the tip angle of described straight internal bevel gear; A plurality of shrinkage pools 17 that are used to support ball-type rolling element 16 are set on the cartridge type ball-collecting rack 15 of described centripetal out-beat bearing 14, and the upper end of described rolling element 16 is provided with lid 18, and described rolling element 16 protrudes in the inner surface of ball-collecting rack 15; Eccentric spindle nose 12 ends of described input mechanism 1 are provided with bascule 6.Be provided with mechanically-sealing apparatus 3 between described input mechanism 1 and the casing 5.
The present invention is a kind of, and to be used for the gear drive described in the reducer of pipeline or down-hole be difference planetary cone gear transmission mechanism, little in order to guarantee that the reducer overall dimension is tried one's best, use to meet in pipeline or down-hole narrow space, the pressure angle of described straight bevel gear is α=11 ° or α=12 ° or α=15 °, for described gear drive is guaranteed steadily in the course of the work, the friction pair of oscillating bearing or self-aligning bearing structure can be set in described gear drive, according to working condition, 6 or 12 rolling elements 16 can be set on the described centripetal out-beat bearing 14, arc groove 19 on the rolling element 16 on the described centripetal out-beat bearing 14 and the ball surface 20 of described straight internal bevel gear 7 matches, described bascule 6 is the bent plate shape, and be provided with balance weight mechanism, be provided with high speed shaft bearing 4 and parts of bearings between described input mechanism 1 and the casing 5, be provided with slow-speed shaft bearing 9 and parts of bearings between described output mechanism 11 and the casing 5, the two ends of described casing 5 are respectively arranged with down adpting flange 2 and last adpting flange 10.
From Fig. 1, Fig. 2, Fig. 3 and Fig. 4 as can be seen, a kind of gear reduction transmission mechanism that reducer adopted that is used for pipeline or down-hole is a kind of difference planetary cone gear transmission mechanism among the present invention, describes the transmission process of this gear drive below in detail.
When input mechanism 1 drives eccentric spindle nose 12 on the beat generator around fixed axis, when promptly the center line of input mechanism 1 rotates, the cone-beam space that it is 2 times of cone angles that eccentric spindle nose 12 and axis just form a cone-apex angle.At this moment, the straight internal bevel gear 7 that is contained on the eccentric spindle nose 12 is subjected to the circumferentially constraint of rotation, can not rotate, but the motion of the cone-beam of eccentric spindle nose 12 forces straight internal bevel gear 7 to do the circulation oscillating motion around the o point, and forms engagement, the disengaged condition that circulates with the outer bevel gear 13 of passive straight-tooth that is contained on the output mechanism 11.Eccentric spindle nose 12 is in the position shown in the figure 1 the time, and straight bevel gear is engagement in the upper end, and is complete disengaged condition in the lower end; When eccentric spindle nose 12 turned over 180 °, straight bevel gear was engagement in the lower end, then threw off fully in the upper end.When eccentric spindle nose 12 turns over 180 ° again, then get back to upper end engagement again and the reset condition that throws off fully the lower end, at this moment, straight internal bevel gear 7 has been finished a beat engagement circulation just.Obviously, at eccentric spindle nose 12 in the fixed axis rotation process, do the gear teeth on the straight internal bevel gear 7 of beat motion then along the circumferential direction and constantly enter with the outer bevel gear 13 of straight-tooth on gear teeth meshing then withdraw from the engagement that moves in circles that engagement throws off with it again, throw off motion, thus, mesh regional is shifted along the pitch cone of passive straight internal bevel gear 7.In this shuttling movement, work as Z to straight bevel gear engagement, disengagement
1＞Z
2The time, it's a week if driving straight internal bevel gear 7 revolutions, pasts eccentric spindle nose 12, the outer bevel gear 13 of then passive straight-tooth turns over Z in the opposite direction
1-Z
2Individual tooth, thus realized that gearratio is the deceleration transmission of Z2/ (Z1-Z2).
A kind of reducer of the present invention is the long and narrow space that is used in pipeline or down-hole, so, its radial dimension has certain restriction, in order to reach designing requirement, the span of pressure angle α in the described difference planetary cone gear transmission mechanism is α=11 °～20 °, preferably α=11 ° or α=12 ° or α=15 °; In addition, because the surface at described straight internal bevel gear 7 tooth top places is the ball-type surface, so the tip diameter of described straight internal bevel gear=internal bevel gear body sphere diameter * Sin δ
A1, wherein, δ
A1It is the tip angle of this gear.
When a kind of reducer that is used for pipeline or down-hole of the present invention is worked; input mechanism 1 is connected with the output of high-speed electric expreess locomotive protector; the high rotary speed movement that motor produces passes to the input mechanism 1 of reducer through motor protecter; the straight internal bevel gear 7 that described input mechanism 1 drives on the eccentric spindle nose 12; under the circumferential limit rotation of centripetal out-beat bearing 14; make straight internal bevel gear 7 produce swing; reach straight internal bevel gear 7 and the engagement that is positioned at the outer bevel gear 13 formation circulation foldings of straight-tooth on the output mechanism 11 with this; the frequency of straight internal bevel gear 7 beats under the effect of difference tooth, can form the retarded motion by certain speed reducing ratio transmission to the outer bevel gear 13 of the straight-tooth on the output mechanism 11.In addition, eccentric shaft head end at input mechanism 1 is provided with bascule 11, and balancing weight is set according to the weight and the rotating speed of straight internal bevel gear 7, be used for overcoming because straight internal bevel gear 7 at the centrifugal force that swing process produced, makes the operation of reducer complete machine more steady.
The embodiment of a kind of reducer of the present invention is as shown in Figure 1: its length overall is about the cylindrical chassis 5 of 650mm, the external diameter of casing 5 can be determined according to different hole diameters, its span is between φ 98mm to φ 143mm, applicablely in 5-1/2 inch or the oil well casing more than 7 inches, use, a kind of reducer of the present invention is owing to adopt conical gear difference tooth planetary gear speed reducing mechanism to realize slowing down, therefore can be according to the pump setting depth of used screw pump, discharge capacity and medium rerum natura are selected the number of teeth of gear, reach the gearratio that the optimum speed with pump is complementary with this, input mechanism 1 is by the roller bearings on the high speed shaft bearing 4, in order to reach the isolation of well liquid and lubricating fluid, in reducer, be provided with mechanically-sealing apparatus 3, make the inner cavity that forms two isolation of reducer, as mentioned above, under the effect of hoop rotation limting mechanism 8, can produce swing at straight internal bevel gear described in the difference planetary cone gear transmission mechanism 7, in order to guarantee the complete machine running steadily, offset the centrifugal force that is produced by swing with bascule 6, output mechanism 11 is by the roller bearings that is fixed on the slow-speed shaft bearing 9.Reducer of the present invention adopts circulating lubricating mode in the oil immersion, and interior circulating lubricating and cooling are provided by the reducer protective device.
According to the different operating situation, provide the following data of respectively organizing:
| Operating mode | The motor model | The internal bevel gear tooth number Z 1 | Outer cone gear tooth number Z 2 | Gearratio |
