Embodiment Construction
[0023] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with this application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as recited in the appended claims.
[0024] Refer to the attached figure 1 , this specific embodiment provides a reducer, which is used in a submersible screw pump system to reduce the rotational speed of the output end of the motor and transmit it to the screw pump. The reducer includes a first-stage planetary gear assembly and a second-stage planetary gear assembly. The gear assembly, the first-stage planetary gear assembly and t...

The invention discloses a decelerator for a submersible progressing cavity pump system. The decelerator comprises a first stage planetary gear assembly and a second stage planetary gear assembly; thefirst stage planetary gear assembly and the second stage planetary gear assembly comprise sun gears, planetary gear sets meshing with the sun gears, gear rings sleeving the outer parts of the planetary gear sets and meshing with the planetary gear sets and planetary frames used for fixing the planetary gear sets; the sun gear of the first stage planetary gear assembly is connected with the outputend of a motor, the planetary frame of the first stage planetary gear assembly is connected with the sun gear of the second stage planetary gear assembly, and the planetary frame of the second stage planetary gear assembly is connected with a progressing cavity pump; the second stage planetary gear assembly is provided with a plurality of sets of the planetary gear set, and the multiple sets of the planetary gear set are all arranged side by side in the axial direction of the sun gear and all mesh with the sun gear and the gear ring of the second stage planetary gear assembly. According to thearrangement of the decelerator for the submersible progressing cavity pump system, the problems that only the decelerator with a small module of gear can be selected and used due to the limit of theoil well space, and the bearing capacity and the service life of the decelerator are limited badly are solved.
Description
technical field [0001] The present application relates to the technical field of petroleum exploitation and water injection equipment, and more particularly, to a reducer used in a submersible screw pump system. Background technique [0002] In the related art, the submersible screw pump system is a mechanical oil production equipment that has developed rapidly in recent years. In heavy oil and sand production wells, the system is becoming an important way to replace the oil pumping unit. The existing submersible screw pump In the system, the submersible motor and multi-stage planetary gear reducer are mostly used to obtain the low speed and high torque required for the working of the screw pump, and because the oil well space is limited, the outer diameter should not be too large. In this case, the planetary gear The gear module of the reducer can only be selected very small, which seriously limits its bearing capacity and service life. [0003] Therefore, how to solve the...
