[0002] Planetary gearbox is also called planetary reduction box, which is a mechanism in which multiple planetary gears rotate around a sun gear. It is also a mechanism that reduces the transmission speed ratio and increases the motor torque proportionally.

[0003] After searching, the patent with announcement number CN216361129U discloses a planetary gearbox, which relates to the field of gearboxes, including: a gearbox body, a transmission shaft, a heat dissipation mechanism and a mounting mechanism, wherein the transmission shaft is rotatably mounted inside the gearbox body, mounting mechanisms are arranged at both ends of the gearbox body, and heat dissipation mechanisms are arranged at the opposite ends of the two groups of mounting mechanisms, and the heat dissipation mechanisms include a clamping ring, a bump, a mounting frame, a ventilation fan, a mounting plate and a fixing screw. The utility model uses the heat dissipation mechanism to drive the ventilation fan to rotate through the rotation of the transmission shaft when in use, and introduces the outside air into the interior of the gearbox body, and then another group of heat dissipation mechanisms discharges it, so that a fast-flowing air duct is formed inside the gearbox body, thereby greatly improving the heat dissipation efficiency and effectively ensuring the service life of the gears inside the gearbox body; the mounting mechanism can facilitate the maintenance of the gearbox body.

[0004] The technical solution has the following problems:

[0005] Although the heat dissipation of the planetary gearbox body can be achieved through a heat dissipation mechanism, the planetary gearbox is exposed to the outside during use. If the four sides of the planetary gearbox are subjected to external impact and bumps during use, it is easy to cause damage to the internal components of the planetary gearbox. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that although the heat dissipation mechanism can be used to dissipate the heat of the planetary gearbox body, the planetary gearbox is exposed to the outside during use. If the four sides of the planetary gearbox are subjected to external impact during use, bumps will occur, which may easily cause damage to the internal components of the planetary gearbox. A high-reliability planetary gearbox is proposed to solve the problem.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] Embodiment 1

[0028] Reference Figure 1-4 A high-reliability planetary gearbox is used in the field of planetary gearboxes, including: a gearbox body 1, which is the main part of the planetary gearbox. A protective mechanism is provided on the gearbox body 1. The protective mechanism is used to provide all-round protection for the four sides of the gearbox body 1 to prevent external objects from colliding with and damaging the gearbox body 1.

[0029] The protective mechanism is mainly composed of a first frame 2 and a second frame 7, which are respectively located on both sides of the gear box body 1. On the inner walls on both sides of the first frame 2 and the inner walls on both sides of the second frame 7, two blocking blocks 11 are fixedly set. These blocking blocks 11 can further enhance the protective effect and prevent the gear box body 1 from being damaged when impacted.

[0030] The fixing mechanism is used to firmly fix the first frame 2 and the second frame 7 on the gear box body 1. Specifically, the fixing mechanism includes two first mounting plates 3 and two second mounting plates 4. The sides of the two first mounting plates 3 close to each other are fixedly connected to the two sides of the first frame 2, and the two second mounting plates 4 are fixedly connected to the two sides of the second frame 7. Two circular holes are opened on each first mounting plate 3, and a bolt 5 is arranged in each circular hole. Correspondingly, two threaded holes are opened on the second mounting plate 4. One end of the bolt 5 can pass through the circular hole and be threadedly connected to the threaded hole, thereby realizing the fixation of the first frame 2 and the second frame 7 to the gear box body 1.

[0031] Embodiment 2

[0032] refer to Figure 1-4 , improved on the basis of the first embodiment:

[0033] In order to improve the heat dissipation performance of the gear box body 1, we opened a square hole on one side of the first frame 2 and fixed a fan 9 in the square hole. The fan 9 can continuously blow air to dissipate heat to the gear box body 1 to prevent performance degradation or damage due to overheating. At the same time, in order to further improve the heat dissipation effect, we opened ventilation holes 8 on the first frame 2 and the second frame 7. These ventilation holes 8 help to quickly dissipate the heat inside the gear box body 1.

[0034] In addition, in order to prevent the first frame 2 and the second frame 7 from sliding on the gear box body 1, we fixedly set two plug-in blocks 10 on the side where the first frame 2 and the second frame 7 are close to each other, and on both sides of the gear box body 1, we opened slots 12 corresponding to the plug-in blocks 10, and the plug-in blocks 10 can be inserted into the slots 12, thereby increasing the stability of the entire protective mechanism.

[0035] Finally, in order to further improve the protection of the fan, we set a cover 6 on one side of the first frame 2. This cover 6 can cover the fan 9 to prevent the fan 9 from being directly impacted by external objects. At the same time, through holes are opened on the cover 6 to ensure normal ventilation and heat dissipation of the fan 9. This cover 6 can be conveniently fixed to the first frame 2 by screws to facilitate future maintenance and replacement.

[0036] The model of the gearbox main body 1 is the planetary reducer AB060L2-64-P2-S2. The gearbox main body 1 is the existing technology. The working principle of the gearbox main body 1 will not be repeated here, and it can also be purchased according to actual needs.

[0037] However, as is well known to those skilled in the art, the working principle and wiring method of the fan 9 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
