Description

Technical Field

[0001] This utility model relates to the technical field of planetary gears and related technologies, and in particular to a planetary gear structure for a flange-type internal gear ring compact submersible pump. Background Technology

[0002] Please see now. Figure 1 As shown, in existing planetary gearboxes, the internal gear ring 3' is fixedly mounted on the gearbox body 1' using guide keys 2' and fastening screws 4'. The internal gear 3' and the gearbox body 1' are interference-fitted, and the guide keys 2' prevent the internal gear 3' and the gearbox body 1' from rotating. Then, the left side of the gearbox body 1' is connected to the submersible motor, and the right side is connected to the guide vane body, water pump shaft, and other components, thus forming a complete submersible pump. However, the existing structure is relatively complex, the overall weight is large, and the manufacturing cost is high. Furthermore, since the gearbox body 1' is generally a welded part, and submersible pumps are mostly used underwater, the welded parts of the gearbox body 1' are prone to weld detachment under the impact of water flow, resulting in water leakage from the submersible pump.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0023] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0024] like Figure 2 The diagram shows a preferred embodiment of a planetary gear structure for a flange-type internal gear ring compact submersible pump, which includes: a hollow shaft 1, a drive gear 2, a planet carrier 3, planetary gears 4, and a baffle 5.

[0025] The driving gear 2 is mounted on the hollow shaft 1; the baffle 5 is mounted on the planet carrier 3 and abuts against the driving gear 2; the planet gear 4 is mounted on the planet carrier 3 via the bearing 6 and meshes with the driving gear 2; the internal gear ring 8 is mounted on the guide vane body 9 and meshes with the planet gear 4.

[0026] In actual use, the hollow shaft 1 transmits power to the drive gear 2. The rotation of the drive gear 2 drives the planetary gear 4 to rotate, which in turn drives the internal gear ring 8 to rotate. The rotation of the internal gear ring 8 drives the guide vane body 9 to rotate. This device flanges the internal gear ring 8, allowing it to be directly installed with the guide vane body 9, eliminating the gearbox body. This results in a compact and simple structure, effectively reducing the overall weight of the submersible pump. Furthermore, the flanged internal gear ring 8 does not have a gearbox body; the outer casing is generally a cast guide vane body or a flow guide cover, which can effectively prevent water leakage.

[0027] Based on the above, this utility model also has the following embodiments:

[0028] Furthermore, a planetary gear structure for a flange-type internal gear ring compact submersible pump is provided, wherein an opening 13 is provided on one surface of the planet carrier 3, and the driving gear 2 extends into the interior of the planet carrier 3 through the opening 13, and the axis of the hollow shaft 1, the axis of the planet carrier 3 and the axis of the planetary gear 4 are located on the same straight line.

[0029] Furthermore, a planetary gear structure for a flange-type internal gear ring compact submersible pump is provided, wherein the outer wall of the planet carrier 3 is provided with a mounting hole 14, and the planetary gear 4 is mounted in the mounting hole 14 via a bearing 6.

[0030] Furthermore, a planetary gear structure for a flange-type internal gear ring compact submersible pump further includes: a fixed shaft 7; the fixed shaft 7 passes through one side of the mounting hole 14, the bearing 6, and is fixed to the other side of the mounting hole 14.

[0032] Furthermore, in a planetary gear structure of a flange-type internal gear ring compact submersible pump, a ejector pin 12 is mounted on a baffle 5. One end of the ejector pin 12, passing through the baffle 5, has a spherical structure 11. The spherical structure 11 abuts against the drive gear 2 via a pad 10. Specifically, the ejector pin 12 and the pad 10 prevent axial movement of the drive gear 2. The spherical structure 11 of the ejector pin 12 reduces the contact area with the pad 10, reducing friction. Furthermore, when the pad 10 is damaged, it can be replaced, effectively increasing the service life of the drive gear 2.

[0033] Furthermore, a planetary gear structure for a flange-type internal gear ring compact submersible pump is provided, wherein the internal gear ring 8 and the guide vane body 9 are fixed by bolts.
