Description

Technical Field

[0001] This utility model relates to the field of sun gear technology, specifically to a sun gear that is easy to install. Background Technology

[0002] A sun gear is a mechanical forging, referring to a part in a planetary gear system that can be used as a central gear or external gear. Sun gears have advantages such as lightweight, good wear resistance, high working efficiency, good shock absorption, impact resistance, strong load-bearing capacity, and good stability. They are widely used in many fields such as automobile manufacturing, robot manufacturing, machining, and wind power generation.

[0003] Patent document CN221990885U discloses a sun gear assembly that is easy to install. It discloses that "the elastic metal sheet continuously presses the spindle to be installed under its own elastic force, and the spindle will not slide in the spindle hole without external support, which facilitates the subsequent installation work of the worker. Furthermore, the positioning blocks are inserted into the mounting holes of the flange to be installed. The positioning blocks in the eight connection holes are respectively inserted into the mounting holes of the flange to be installed, thereby positioning the position of the flange to be installed. After installing a mounting bolt, the mounting holes of the flange to be installed without the mounting bolt are still limited and positioned by the positioning blocks. The unfixed mounting flange is not easy to move, which facilitates the operation of the worker."

[0004] However, the sun gear assembly in the aforementioned published literature mainly addresses the problem that existing sun gears are inconvenient to install. However, the installation of this sun gear assembly is carried out through a structure such as positioning blocks, mounting flanges, and mounting bolts. This installation and positioning structure is complex, which does not effectively improve the installation efficiency of the sun gear.

[0005] In view of this, it is necessary to develop a sun gear that is easy to install, thereby further improving the installation efficiency of the sun gear. Utility Model Content

[0006] The purpose of this utility model is to provide a sun gear that is easy to install, so as to solve the technical problem mentioned in the background art that the installation and positioning structure is complicated and the installation efficiency of the sun gear cannot be effectively improved.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sun gear that is easy to install, comprising: a sun gear body, wherein a limiting lubrication assembly is installed on the top of the sun gear body, the limiting lubrication assembly is used to lubricate the shaft connected to the sun gear, the limiting lubrication assembly includes a mounting ring, a lubrication sleeve and a limiting groove, the mounting ring is installed on the top of the sun gear body, the lubrication sleeve is installed on the inner side of the mounting ring, and the limiting groove is formed on the inner side of the lubrication sleeve.

[0008] Preferably, the top of the sun gear body is provided with a through mounting hole, the mounting hole extends through the bottom of the sun gear body, and the mounting hole corresponds vertically to the limiting lubrication component. A positioning groove is provided on the inner side of the mounting hole, and the positioning groove corresponds to the limiting groove.

[0009] Preferably, the top and bottom of the sun gear body are respectively provided with multiple fixing holes, and the fixing holes are located outside the mounting holes. The outer side of the sun gear body is provided with meshing teeth.

[0011] Preferably, a pull plate is installed on the top of the protective shell, and a sealing ring is installed on the bottom of the protective shell via a friction positioning shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the limiting lubrication assembly is installed on the top of the mounting hole via an mounting ring. The lubrication sleeve installed inside the mounting ring can absorb lubricating oil. When the sun gear is connected to the shaft through the mounting hole, the shaft will pass through the limiting lubrication assembly, which will squeeze the lubrication sleeve in the lubrication assembly, causing the lubricating oil in the lubrication sleeve to be squeezed out. This allows the lubricating oil on the lubrication sleeve to lubricate the shaft, making the installation of the sun gear through the mounting hole smoother and faster.

[0014] 2. In order to prevent impurities from adhering inside the sun gear body, the protective shell is inserted into the fixing hole by friction positioning shaft, so that the protective shell is installed on the top and bottom of the sun gear body, thereby preventing impurities from entering the installation hole and affecting the installation quality between the sun gear body and the shaft, and also preventing wear.

[0023] Please see Figure 1 and Figure 4 A sun gear that is easy to install;

[0024] The device includes: a sun gear body 1 and a limiting lubrication assembly 5. The limiting lubrication assembly 5 is installed on the top of the sun gear body 1. The limiting lubrication assembly 5 is used to lubricate the shaft connected to the sun gear. The limiting lubrication assembly 5 includes a mounting ring 6, a lubrication sleeve 7 and a limiting groove 8. The mounting ring 6 is installed on the top of the sun gear body 1. The lubrication sleeve 7 is installed on the inner side of the mounting ring 6. The limiting groove 8 is opened on the inner side of the lubrication sleeve 7. The top of the sun gear body 1 is provided with a mounting hole 4. The mounting hole 4 is provided through the bottom of the sun gear body 1 and the mounting hole 4 is vertically corresponding to the limiting lubrication assembly 5. The inner side of the mounting hole 4 is provided with a positioning groove 3 and the positioning groove 3 is corresponding to the limiting groove 8.

[0025] The sun gear body 1 provides a position for the installation of the limiting lubrication assembly 5. The limiting lubrication assembly 5 is installed on the top of the mounting hole 4 via the mounting ring 6. The lubrication sleeve 7 installed inside the mounting ring 6 can absorb lubricating oil. When the sun gear is connected to the shaft through the mounting hole 4, the shaft will pass through the limiting lubrication assembly 5, which will squeeze the lubrication sleeve 7 in the lubrication assembly 5, causing the lubricating oil in the lubrication sleeve 7 to be squeezed out. This allows the lubricating oil on the lubrication sleeve 7 to lubricate the shaft, making the installation of the sun gear through the mounting hole 4 smoother and faster. Since the limiting groove 8 corresponds to the positioning groove 3, when the installed shaft passes through the limiting lubrication assembly 5, the positioning part on the shaft that is fitted with the positioning groove 3 is first limited by the limiting groove 8, so that the shaft can be directly fitted into the mounting hole 4 during installation without having to align the positioning part with the positioning groove 3.

[0026] Please see Figure 1 and Figure 4 A sun gear that is easy to install;

[0027] The sun gear body 1 includes a fixing hole 11 and a protective shell 9. Multiple fixing holes 11 are opened through the top and bottom of the sun gear body 1, and the fixing holes 11 are located outside the mounting hole 4. The outer side of the sun gear body 1 is provided with meshing teeth 2. The top and bottom of the sun gear body 1 are respectively installed with a protective shell 9. Multiple friction positioning shafts 13 are installed at the bottom of the protective shell 9, and the friction positioning shafts 13 correspond to the fixing holes 11. The top of the protective shell 9 is installed with a pull plate 10, and the bottom of the protective shell 9 is installed with a sealing ring 12 through the friction positioning shafts 13.

[0028] The sun gear body 1 provides a location for the fixing hole 11, and the fixing hole 11 provides space for the fixing of the protective shell 9. In order to prevent impurities from adhering inside the sun gear body 1, the protective shell 9 is rubbed into the interior of the fixing hole 11 by the friction positioning shaft 13, so that the protective shell 9 is installed on the top and bottom of the sun gear body 1, thereby preventing impurities from entering the interior of the mounting hole 4 and affecting the installation quality between the sun gear body 1 and the shaft, and also preventing wear. The pull plate 10 is used to remove the protective shell 9, and the sealing ring 12 makes the sealing performance of the protective shell 9 better after installation.

[0029] Working principle: First, the protective shell 9 is taken out by pulling the plate 10. The shaft that needs to be connected and installed with the sun gear is inserted into the mounting hole 4 through the limiting lubrication component 5, so that the sun gear is installed on the outside of the shaft. When the shaft passes through the limiting lubrication component 5, it will squeeze the lubrication ring 7, causing the internal lubricating oil to flow out. The lubricating oil in the lubrication ring 7 lubricates the shaft, making the installation of the sun gear smoother and more convenient.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
