Description

Technical Field

[0001] This utility model relates to the technical field of through-shaft internal rotor speed reducers, specifically a through-shaft internal rotor speed reducer with heat dissipation fins. Background Technology

[0002] The through-shaft internal rotor reducer is supported and installed with a coaxial core component. It is used in conjunction with an integrated motor body and a planetary reduction mechanism. Its main function is to achieve speed reduction and torque increase and to efficiently transmit power. It is widely used in electric vehicles, automated production, robotics and other fields.

[0003] For example, a planetary gear assembly for a tubular motor reducer, as disclosed in CN218118491U, includes a tubular housing. A reducer frame and a motor are fixedly mounted on the inner wall of the tubular housing. A spindle is fixedly mounted on the output shaft end of the motor. A reducer sleeve a is fitted around the outside of the spindle. A reducer sleeve b is fitted around the circumferential side of reducer sleeve a. A reducer sleeve c is fitted around the circumferential side of reducer sleeve b. An output terminal is fixedly mounted on the top of reducer sleeve c. Internal gears are fixedly mounted on the circumferential sides of the spindle, reducer sleeve a, and reducer sleeve b. Planetary assemblies are installed on the inner wall of the reducer frame at the positions corresponding to the three internal gears. This device, through the arrangement of planetary gears, external gear rings, and internal gears, enables the device to efficiently complete the deceleration operation of the tubular motor.

[0004] Most of the aforementioned existing technologies improve the overall structure. However, existing through-shaft internal rotor reducers are mostly encased in metal shells during operation. Although this provides effective protection, in actual use, the internal gas may not circulate with the outside, leading to excessively high internal temperatures and affecting the normal operation of the device. Summary of the Invention

[0005] The purpose of this invention is to provide a through-shaft internal rotor speed reducer with heat dissipation fins to solve the problem of high internal temperature in the existing through-shaft internal rotor speed reducers mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a through-shaft type internal rotor reduction device with heat dissipation fins, comprising a protective component, an output motor disposed inside the protective component, and a reduction component slidably mounted inside the output motor; the output motor includes a self-heating adjustment component, which rotates within the protective component through its internal structure, thereby driving air circulation within the device and accelerating heat dissipation; the reduction component includes a self-disassembly component, which is mutually restrained by its internal structure, facilitating disassembly and replacement during subsequent maintenance.

[0007] Furthermore, the protective assembly includes a first fixing plate, on which a first fin plate is fixedly mounted, and on the side of the first fin plate away from the first fixing plate, a gear ring is fixedly mounted.

[0008] Furthermore, a second fin plate is fixedly installed on the side end of the gear ring away from the first fin plate, and a second fixing plate is fixedly installed on the side end of the second fin plate away from the gear ring.

[0009] Furthermore, the self-heating adjustment component includes a mounting shell, on the outer surface of which four connecting rods are fixedly mounted, and inside the mounting shell, a rotating shaft is rotatably mounted.

[0010] Furthermore, a side sealing plate is slidably installed on the side end of the mounting shell, and four first bolts are slidably installed inside the side sealing plate. The rotating shaft is rotatably installed inside the mounting shell through the side sealing plate and the first bolts.

[0011] Furthermore, a first planetary gear is provided on the outer surface of the rotating shaft, a fan blade is sleeved on the outer surface of the rotating shaft, and a retaining ring is provided on the outer surface of the rotating shaft at the side end of the fan blade.

[0012] Furthermore, the self-disassembly assembly includes a first limiting plate, which is disposed on the side end of the first planetary gear. Four rotating rods are rotatably mounted on the side end of the first limiting plate in the same direction as the first planetary gear. A second planetary gear is fixedly sleeved on the outer surface of each rotating rod. Each second planetary gear meshes with the first planetary gear and also meshes with the gear ring.

[0013] Furthermore, the same second limiting plate is fitted onto the side end of each of the rotating rods on the side away from the first limiting plate, and heat dissipation holes are opened inside each of the second limiting plate and the first limiting plate.

[0014] Furthermore, each of the four inner corners of the second limiting plate is slidably installed with a second bolt, and the side end of each second bolt passes through the second limiting plate and simultaneously passes through the first limiting plate to be installed in the opening at the side end of the connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This through-shaft type internal rotor reduction device with heat dissipation fins rotates the rotating shaft during use, thereby driving the fan blades to rotate. In conjunction with the gap between the first fin plate and the second fin plate, as well as the heat dissipation holes opened inside the second limiting plate and the first limiting plate, the device can drive the surrounding air into the device to circulate air during use, thereby improving the heat dissipation capacity of the device and enhancing the device's performance. Furthermore, by installing or removing the second bolt, it is convenient to quickly detach structures such as heat dissipation holes, rotating rods, and second planetary gears, thereby facilitating replacement operations during subsequent maintenance and improving the efficiency of device maintenance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to Figures 1-6A through-shaft internal rotor reduction device with heat dissipation fins is disclosed to address the problem of poor heat dissipation in existing through-shaft internal rotor reduction devices. The device includes a protective component 1, with an output motor 2 housed inside the protective component 1. A reduction component 3 is slidably mounted inside the output motor 2. The output motor 2 includes a self-heating adjustment component, which, through its internal structure, rotates within the protective component 1, thereby promoting airflow within the device and accelerating heat dissipation. The reduction component 3 includes a self-disassembly and assembly component, which, through its internal structure, mutually limits each other during installation, facilitating subsequent inspection. During repair, it can be disassembled and replaced. The self-heating adjustment component includes a mounting shell 21. Four connecting rods 22 are fixedly installed on the outer surface of the mounting shell 21. A rotating shaft 25 is rotatably installed inside the mounting shell 21. A side sealing plate 23 is slidably installed on the side end of the mounting shell 21. Four first bolts 24 are slidably installed inside the side sealing plate 23. The rotating shaft 25 is rotatably installed inside the mounting shell 21 through the side sealing plate 23 and the first bolts 24. A first planetary gear 26 is provided on the outer surface of the rotating shaft 25. A fan blade 27 is sleeved on the outer surface of the rotating shaft 25. A fixing ring 28 is provided on the outer surface of the rotating shaft 25 at the side end of the fan blade 27.

[0020] When the user operates the device, the rotating shaft 25, in conjunction with the fixing ring 28, causes the fan blades 27 to rotate. The rotating fan blades 27 draw air into the device through the gaps in the second fin plate 14. After entering the device, the air flows along the heat dissipation holes 35 in the second limiting plate 34 and the first limiting plate 31. Combined with the air flow driven by the rotation of the fan blades 27, the air entering the device is blown towards the mounting shell 21. When blown into the mounting shell 21, the air diffuses outward through the gaps between the first fin plates 12, thus allowing air circulation inside the device. Since the stator inside the device is directly connected to the inner walls of the mounting shell 21 and the side sealing plate 23, heat can be transferred into the mounting shell 21 and the side sealing plate 23 when the stator is working. Combined with the air circulation driven by the fan blades 27, this accelerates the heat dissipation operation of the mounting shell 21 and the side sealing plate 23. During heat dissipation, the second fin plate 14 and the first fin plate 12 facilitate airflow.

[0021] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, further discloses, in order to solve the problem that it is difficult to replace internal parts in existing through-shaft internal rotor reduction devices, that: the protective assembly 1 includes a first fixing plate 11, a first fin plate 12 is fixedly installed on the side end of the first fixing plate 11, a gear ring 13 is fixedly installed on the side end of the first fin plate 12 away from the first fixing plate 11, a second fin plate 14 is fixedly installed on the side end of the gear ring 13 away from the first fin plate 12, and a second fixing plate 15 is fixedly installed on the side end of the second fin plate 14 away from the gear ring 13. The self-disassembly assembly includes a first limiting plate 31, which is disposed on the side end of the first planetary gear 26 and connected to the first row... Four rotating rods 32 are rotatably mounted on the side end of the first limiting plate 31 in the same direction as the planetary gear 26. A second planetary gear 33 is fixedly sleeved on the outer surface of each rotating rod 32. Each second planetary gear 33 meshes with the first planetary gear 26 and also meshes with the gear ring 13. The side end of each rotating rod 32 away from the first limiting plate 31 is sleeved with the same second limiting plate 34. Each second limiting plate 34 and the first limiting plate 31 have heat dissipation holes 35 inside. Each second limiting plate 34 has a second bolt 36 slidably installed at the four corners inside. The side end of each second bolt 36 passes through the second limiting plate 34 and the first limiting plate 31 and is installed in the side opening of the connecting support rod 22.

[0022] The user removes part of the protective component 1 of the device, exposing the output motor 2 and the reduction component 3. Then, the mounting shell 21 is placed on a horizontal surface with the heat dissipation hole 35 facing upwards. Next, the second bolt 36 is removed along the outer surface of the second limiting plate 34. Then, the fixing ring 28 and the fan blade 27 are removed. Then, the second limiting plate 34 is removed. After removing the second limiting plate 34, the second planetary gear 33 and the rotating rod 32 will be exposed. At this time, the rotating rod 32 can be pulled upwards to separate and replace it from the first limiting plate 31 and other structures. Similarly, the first planetary gear 26 can be disassembled and replaced by pulling upwards.
