[0025] 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.

[0026] 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.

[0027] like Figures 1 to 3 The diagram shows a preferred embodiment of a planetary gear bearing lubrication structure for a vertical planetary reducer, comprising: a planet carrier 1, a bearing 2, planetary gears 4, a planetary shaft 3, an internal gear ring 5, and an oil receiving pan 6.

[0028] An oil receiving pan 6 is installed on the end face of the planetary carrier 1. The planetary carrier 1 has several planetary shaft holes, and several first through holes 7 are provided near each planetary shaft hole. An oil groove 9 is provided on the web of the planetary carrier 1, and a second through hole 10 is provided at the bottom of the oil groove 9. Each planetary shaft 3 passes through one end of the planetary shaft hole, two bearings 2 and the other end of the planetary shaft hole in sequence, fixing the two bearings 2 to the planetary carrier 1. The planetary gear 4 is installed on the outer wall of the two bearings 2. The internal gear ring 5 is installed on the outer wall of the planetary gear 3 and meshes with the planetary gear 4. The planetary gear 4 has several third through holes 11 along its radial direction, and the several third through holes 11 are connected from the outer wall of the planetary gear 4 to the inner wall of the planetary gear 4. The planetary shaft 3 has an oil collecting groove 12 along its axial direction, and the planetary shaft 3 has a fourth through hole 13 connected from the oil collecting groove 12 to the space between the two bearings 2.

[0029] In practical use, this device is equipped with multiple lubrication channels. The oil receiving tray 6 on the planetary carrier 1 can collect the lubricating oil left on top. The lubricating oil flows into the planetary carrier 1 through the first through hole 7, which is circumferentially opened at each planetary shaft hole position on the planetary carrier 1. The first through hole 7 connects the outside of the planetary carrier 1 to its inside. The lubricating oil flows into the planetary carrier 1 through the first through hole 7 to lubricate the bearing 2 and planetary gear 4. When the planetary carrier 1 rotates, the lubricating oil inside is thrown out due to inertia and centrifugal force. The lubricating oil spinning inside is blocked by the web plate 8 and then accumulates at the sunken oil groove 9 of the web plate 8. It then flows out downward through the second through hole 10 from the inside to lubricate the planetary gear 4 and the internal gear ring 5. The planetary gear has a radial third through hole 11 at the circumferential tooth groove position, so that when the planetary gear 4 and the internal gear ring 5 mesh, the lubricating oil squeezed out can flow into the planetary gear 4 through the third through hole 11 to lubricate the bearing 2. The lubricating oil can also flow into the bearing 2 through the oil collection groove 12 and the fourth through hole 13 of the planetary shaft 3 to lubricate the bearing 2.

[0030] Based on the above, this utility model also has the following embodiments:

[0031] Furthermore, a lubrication structure for planetary gear bearings in a vertical planetary reducer includes an oil receiving pan 6 comprising a first plate and a second plate mounted perpendicularly to each other. The first plate is mounted to the planet carrier 1 by screws. Specifically, the oil receiving pan 6 collects the lubricating oil flowing down from the top, allowing the lubricating oil to lubricate the bearing 2 and the planetary gear 4 through the first through hole 7.

[0032] Furthermore, a lubrication structure for planetary gear bearings in a vertical planetary reducer is provided, wherein the planet carrier 1 has three first through holes 7 arranged around the planetary shaft hole array near each planetary shaft hole. Specifically, each planetary shaft hole has three first through holes arranged around its circumference.

[0033] Furthermore, in a lubrication structure for planetary gear bearings of a vertical planetary reducer, the web 8 of the planet carrier 1 is arranged in an arc-shaped fan shape. Specifically, the arc-shaped fan-shaped web 8 can prevent lubricating oil from entering the oil groove 9.

[0034] Furthermore, a lubrication structure for planetary gear bearings in a vertical planetary reducer includes several third through holes 11 disposed in the tooth grooves of the planetary gear 4. Specifically, when the planetary gear 4 and the internal gear ring 5 mesh, the squeezed lubricating oil flows into the third through holes 10 and then lubricates the bearing 2.

[0035] Furthermore, a lubrication structure for planetary gear bearings in a vertical planetary reducer is provided, wherein a plurality of third through holes 11 are arranged in an array along the circumferential direction of the planetary gear 4.

[0036] Furthermore, a lubrication structure for planetary gear bearings in a vertical planetary reducer is provided, wherein a countersunk hole 14 is recessed inward in the middle of the planetary shaft 3, and an oil collecting groove 12 is disposed in the middle of the countersunk hole 14. Specifically, lubricating oil is first collected through the countersunk hole 14, and then the lubricating oil flows into the bearing 2 through the oil collecting groove 12 and the fourth through hole 13 to lubricate the bearing 2.

[0037] Furthermore, a lubrication structure for planetary gear bearings in a vertical planetary reducer is provided, wherein the fourth through hole 13 is arranged along the radial direction of the planetary shaft 3. Specifically, a spacer is provided at the connection between the oil collection groove 12 and the fourth through hole 13. The spacer has a radial through hole and an annular groove, so that the oil collection groove 12 and the fourth through hole 13 can communicate.
