Embodiment 1

[0037] like figure 1 As shown, this embodiment includes a base plate 1, a slide plate 3, a lead screw 2, a gear commutator and a contact wheel 10. The base plate 1 is fixed on the base of the pumping unit, and the slide plate 3 is slidably installed on the base plate 1 through a dovetail groove structure. And the sliding direction is consistent with the length direction of the belt 11 ; the lead screw 2 is rotatably mounted on the base plate 1 , and the slide plate 3 is connected with the lead screw 2 through threads and can slide under the drive of the lead screw 2 . The above structure is a common structure on various machine tools, and its core function is to achieve the purpose of moving the motor 4 by rotating the lead screw 2 .

[0038] like figure 1 As shown, the gear commutator further includes an input shaft 9, an output shaft 6, an intermediate transmission shaft 8 and four bevel gears 7, wherein a bevel gear 7 is respectively installed on the input shaft 9 and the ...

Embodiment 2

[0042] The difference between this embodiment and the first embodiment lies in that the structure of the contact wheel 10 is optimized.

[0043] like figure 2 As shown, as a further technical solution, the contact wheel 10 is an assembly, including the driving wheel 13, the driven wheel 14, the ring sleeve 23, the sliding plate 15 and the tension spring A17, and the driving wheel 13 is installed on the output shaft through the bearing 22. On the shaft 6, the driven wheel 14 is installed on the output shaft 6 through a flat key, and the sliding piece 15 is slid and inserted on the outer edge of the driving wheel 13 in the radial direction, and is always kept toward the driving wheel 13 under the tension of the tension spring A17. The center moves closer; the inner side of the driven wheel 14 is processed with a ratchet 16 matching the end of the slide 15, and after the slide 15 meshes with the ratchet 16, the driving wheel 13 and the driven wheel 14 rotate synchronously; The ...

Embodiment 3

[0048] In this embodiment, the structure of the contact wheel 10 is further optimized on the basis of the second embodiment.

[0049] like Figure 3-5 As shown, as a further technical solution, a sliding sleeve 18 is also installed in the driving wheel 13, and the sliding plate 15 and the tension spring A17 are installed on the sliding sleeve 18; the sliding sleeve 18 is slid and inserted in the radial direction. on the driving wheel 13, and under the pulling force of another tension spring B20, always keep the movement trend close to the axis of the driving wheel 13; the elastic coefficient of the tension spring B20 is greater than that of the tension spring A17; the side of the sliding sleeve 18 A through hole is provided, and a lock block 19 is slidably installed in the through hole, and lock grooves 21 are respectively arranged on the sliding plate 15 and the driving wheel 13 corresponding to the two ends of the lock block 19 .

[0050] After adopting the above-mentioned ...

Abstract

The invention belongs to the field of oil pumping unit equipment, and in particular relates to a motor position self-adaptive adjuster based on a belt transmission mechanism, including a base plate, a slide plate, a lead screw, a gear commutator and a contact wheel, and the base plate is fixed on the base of the pumping unit On the top, the slide plate is slidably installed on the base plate through the dovetail groove structure, and the sliding direction is consistent with the length direction of the belt; Sliding under the drive of the bar; the gear commutator further includes an input shaft, an output shaft, an intermediate transmission shaft and four bevel gears. The invention realizes the automatic tensioning of the belt by adopting a purely mechanical structure. The technical principle is unprecedented. Compared with the electronically controlled automatic tensioning device often used in the mechanical field, the invention has higher working reliability, rainproof and dustproof, easy maintenance and more applicable It is used for pumping units operating in harsh field environments.

Description

technical field [0001] The invention belongs to the field of oilfield pumping unit equipment, in particular to a motor position self-adaptive adjuster based on a belt transmission mechanism. Background technique [0002] The pumping unit is the most commonly used oil production equipment in oil field production. The structure of the pumping unit includes a motor and a reducer. Both the motor and the reducer are equipped with pulleys, and the two pulleys are connected by a belt. In the actual use process, the belt will become loose after long-term use, that is, the tension will become smaller. At this time, if the tightness of the belt is not adjusted in time, it will cause problems such as insufficient power at the end of the pumping unit and excessive wear of the belt. [0003] At present, there are two main methods to adjust the tension of the pumping unit belt: the first method is to install a tension pulley on the side of the belt, and manually adjust the position of the...
