Abstract
The utility model relates to an oil extraction power transmission device. The oil extraction power transmission device is a speed reducer under an oil well. The oil extraction power transmission device mainly comprises a shaft coupling (1), a flange disk (2), a bearing (3), a distance ring (4), a sealing ring (5), a connecting disk (6), an input gear shaft (8) of a shell body (7), an inner gear (9), an eccentric sleeve (10), a blocking ring (11), an adjusting ring (12), a screw (13), and an output shaft (14). The oil extraction power transmission device is installed under a well, and the oil extraction power transmission device does not occupy a ground. The oil extraction power transmission device has labor saving, material saving, low cost, and safety.
Description
The utility model relates to oil down-hole oil production actuating unit, is down-hole, oil oil field retarder.
The motor of the power transmission system of existing screw pump oil production and retarder all are installed in the ground of well mouth of oil well, and its outputting power will pass through sucker rod, is sent to several kms down-hole, just removes the drive screw pump.This system floor space is big, makes the installation fee height, and transmission efficiency is low, oil recovery overall cost height.Oil well to some special operating mode is more remarkable.
The utility model is changed traditional way, with motor and retarder be directly installed on oil well inner screw pump below.Its objective is that providing a kind of does not take up an area of, easy for installation, freedom from repairs, high efficiency, low cost, safe and reliable down-hole rodless pumping operation transmission system.
The purpose of this utility model is achieved in that the latent oily retarder of lower end and oil-submersible motor direct connection, assemble by retarder body and retarder protector, its upper end directly connect with screw pump, be placed in well inner screw pump below.
The retarder body comprises and is used for the body shaft coupling (1) that connects with motor shaft, the flange plate that connects with electric machine casing (2), what connect with the flange plate the other end is reducer shell (7), and fastenings is bolt (13), and what connect with the shaft coupling the other end is gear shaft (8), power is passed to gear shaft by shaft coupling, gear shaft is passed to internal gear (9), internal gear and second level gear shaft direct connection, transferring power, gear shaft is supported by bearing (3), and is located by distance ring (4) (12).Second level gear shaft is bearing on the housing by eccentric bushing (10) and bearing.Flange plate (2), (6) are sealed by O-ring seal (14) with housing (7).Retarder is the plural serial stage form.Rolling bearing adopts high-temperature refractory steel, and operating temperature is 200 ℃.
The utility model compared with prior art, its advantage and good effect are to be installed on below the well inner screw pump, do not take up an area of, volume is little, the efficient height, freedom from repairs, safe and reliable, easy for installation, overall cost is low, realizes rodless pumping operation.
Further describe below in conjunction with the drawings and specific embodiments:
Fig. 1 is a retarder body sectional view.
(1) is the body shaft coupling among the figure, and (2) are flange plate, and (3) are bearing, (4) be distance ring, (5) are seal ring, and (6) are tie-plate, (7) be housing, (8) be the input gear shaft, (9) are internal gear, and (10) are eccentric bushing, (11) be back-up ring, (12) for adjusting ring, (13) are screw, and (14) are output shaft.
What provide in the enforcement is the retarder of the quaternary structure form of φ 114, the retarder body comprises and is used for the body shaft coupling (1) that connects with motor shaft, the flange plate (2) that links with electric machine casing, what link with the flange plate the other end is reducer shell (7), what link with the shaft coupling the other end is input gear shaft (8), gives the next stage input shaft by internal gear (9) with transmission of power.Retarder is a quaternary structure, and every secondary is a combining unit, the speed ratio can regulate.Main structure body all uses senior superior alloy steel to make installation and processing required precision height.
Claims (3)
1, a kind of latent oily retarder, it is characterized in that the body shaft coupling (1) that connects with motor, the flange plate that connects with electric machine casing (2), the housing (7) that connects with flange plate (2) the other end, with shaft coupling (1) the other end link be the input gear shaft (8), by internal gear (9), transmission of power is gone down, the meshed center distance of input gear shaft (8) and internal gear (9) is guaranteed by eccentric bushing (10), internal gear (9) is placed on the gear shaft of next stage by interference fit, gear shafts at different levels are supported by bearing (3), the centre is located by distance ring (4), and every two-stage centre distance equates, is a unit, the tie-plate (6) that links with next unit is with the seal ring (5) of external world's sealing.
2, retarder according to claim 1 is characterized in that directly being placed between oil-submersible motor and the screw pump, slows down with interior realization 9.5 inches of well casing internal diameters.
3, retarder according to claim 1 is characterized in that retarder is multistage form, and reduction speed ratio can reach 20.
