[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] Depend on Figure 1 , Figure 2 and Figure 3 As shown, a planetary reducer gear lubrication device includes a main machine 1, an outer shell 2, a top shell 3 and a matching groove 4. The outer shell 2 is fixedly installed on the outside of the main machine 1, and the top shell 3 is fixedly installed on the top of the main machine 1. The matching groove 4 is opened inside the top shell 3. A conveying device 5 is arranged inside the top shell 3. The conveying device 5 includes a connecting rod 51, a collecting end 52, a sliding groove 53 and a pulling rod 54. The sliding groove 53 is opened inside the top shell 3. The collecting end 52 is slidably installed inside the sliding groove 53. The top of the collecting end 52 is fixedly installed with a connecting rod 51, which is slidably connected to the top shell 3. The pulling rod 54 is fixedly installed on the top of the connecting rod 51. The conveying device 5 is used to quantitatively input the lubricating oil inside the top shell 3 into the components inside the outer shell 2. An opening and closing device 6 is fixedly installed on the top of the top shell 3. The opening and closing device 6 is used to quickly open the seal of the top shell 3.

[0030] During use, the main machine 1 and the shell 2 are installed to the target position, and then the work of the reducer itself is completed through the normal use of the main machine 1. When it is necessary to add lubricating oil to the inside, the opening and closing device 6 can be used to add sufficient lubricating oil to the inside of the top shell 3. Then, part of the lubricating oil is input into the matching groove 4 through the use of the conveying device 5. By pulling the pulling rod 54, the connecting rod 51 is driven to slide up and down inside the top shell 3. When the collecting end 52 moves toward the upper end, the notch inside the collecting end 52 leaks out and collects a certain amount of lubricating oil. Then, the connecting rod 51 is pressed to make the collecting end 52 return to the inside of the sliding groove 53. The lubricating oil in the notch of the collecting end 52 will automatically flow into the matching groove 4 due to the cooperation of the side matching groove 4, and automatically enter the inside of the shell 2 due to the influence of gravity, so that the lubricating oil automatically enters the components inside the main machine 1 to achieve the purpose of lubrication.

[0031] By the attached Figure 4 As shown, in this embodiment, a limit ring is fixedly installed on the outside of the connecting rod 51 to prevent the connecting rod 51 from moving too far during use, so that the collecting end 52 is completely separated from the sliding groove 53, allowing most of the lubricating oil to enter the main machine 1.

[0032] By the attached Figure 4As shown, in this embodiment, grooves are separately provided at the middle end portion inside the collecting end 52, and rubber rings are symmetrically provided outside the collecting end 52. During use, the opening of the grooves facilitates the collection of the lubricating oil inside the top shell 3, and the design of the rubber ring can prevent the leakage of the lubricating oil and ensure its sealing.

[0033] By the attached Figure 5 As shown, in this embodiment, the matching groove 4 is composed of a receiving groove 41 , a guide groove 42 , a central groove 43 and an inlet 44 , wherein the receiving groove 41 is in communication with the sliding groove 53 .

[0034] By the attached Figure 5 As shown, in this embodiment, the central groove 43 is in a cone shape as a whole, so that the lubricating oil can enter the main machine 1 more stably during use.

[0035] By the attached Figure 6 As shown, in this embodiment, the opening and closing device 6 includes a top cover 61, an engaging end 62 and a threaded end 63, the threaded end 63 is fixedly mounted on the surface of the top shell 3, an oil storage tank 64 is provided inside the top shell 3, the top cover 61 is arranged at the top end of the top shell 3, an engaging end 62 is provided inside the top cover 61, and the engaging end 62 is threadedly engaged with the threaded end 63.

[0036] During use, by rotating the top cover 61, the meshing end 62 is gradually separated from the threaded end 63, and then the oil delivery port can be opened to replenish the lubricating oil inside the oil storage tank 64 in time, and the remaining amount of the lubricating oil inside can also be observed, making the use of the equipment itself more convenient.

[0037] By the attached Figure 6 As shown, in this embodiment, raised plates are fixedly installed at equal intervals on the outside of the top cover 61. During use, the raised plates are set up to enhance the friction between the top cover 61 itself and the palm of the staff, making it easier to save effort when rotating the top cover 61.

[0038] The working principle of the utility model is as follows: when using the utility model, the staff installs the main machine 1 and the shell 2 to the target position, and then completes the work of the reducer itself through the normal use of the main machine 1. When it is necessary to add lubricating oil to the inside, the opening and closing device 6 can be used to add sufficient lubricating oil to the inside of the top shell 3, and by rotating the top cover 61, the meshing end 62 is gradually separated from the threaded end 63, and then the oil delivery port can be opened to timely add the lubricating oil to the oil storage tank 64, and the remaining amount of the internal lubricating oil can also be observed, making the use of the equipment itself more convenient, and then through the delivery device 5, part of the lubricating oil is input into the matching groove 4, and by pulling the pulling rod 54, the connecting rod 51 is driven to slide up and down inside the top shell 3. When the collecting end 52 moves toward the upper end, the notch inside the collecting end 52 leaks out and collects a certain amount of lubricating oil. Then, the connecting rod 51 is pressed to make the collecting end 52 return to the sliding groove 53. The lubricating oil in the notch of the collecting end 52 will automatically flow into the matching groove 4 due to the cooperation of the side matching groove 4, and automatically enter the shell 2 due to the influence of gravity, so that the lubricating oil automatically enters the components inside the main machine 1 to achieve the purpose of lubrication.
