Description

Technical Field

[0001] This utility model belongs to the field of mechanical transmission technology, and specifically relates to a precision planetary reducer. Background Technology

[0002] Precision planetary reducers are high-precision speed reduction devices based on the principle of planetary gear transmission. The core consists of a sun gear, planet gears, an internal gear ring, and a planet carrier. Power transmission and speed reduction and torque increase are achieved through the revolution and rotation of the planet gears. They are characterized by high efficiency, compactness, and small size. Their core advantages are high precision, smooth operation, and strong load-bearing capacity. They are widely used in robots, automated equipment, and other scenarios with stringent requirements for speed and positioning accuracy.

[0003] Existing precision planetary reducers generate a lot of heat during operation, which not only affects the normal operation of the internal gears, but also shortens the overall service life of the internal gears due to prolonged exposure to high temperatures. Therefore, a precision planetary reducer is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a precision planetary reducer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision planetary reducer, comprising a reducer housing, multiple connecting bolts, and four driven gears. The four driven gears are respectively meshed with an internal gear. The four driven gears rotate within a limiting sealing cover. The positions of the four driven gears correspond one-to-one with the positions of four glass observation windows. Limiting rotating rings are fixedly connected to one side surface of each of the four driven gears. The four limiting rotating rings rotate within the reducer housing. Combined shafts are fixedly connected to one side surface of each of the four limiting rotating rings. The four combined shafts rotate within the reducer housing. Cooling fans are fixedly connected to one side surface of each of the four combined shafts. The four cooling fans rotate within the reducer housing. Linkage shafts are fixedly connected to the other side surface of each of the four driven gears. The four linkage shafts rotate within the limiting sealing cover. Cleaning plates are fixedly connected to the surfaces of each of the four linkage shafts. The cleaning surfaces of the four cleaning plates are in contact with the surfaces of the four glass observation windows.

[0006] By setting up a transmission structure consisting of a drive motor, a driving gear, an internal gear, and a driven gear, multiple cooling fans can be synchronously driven to rotate inside the reducer housing via a combined shaft. This accelerates internal air circulation, efficiently dissipates the heat generated by the precision gear reduction assembly, effectively prevents high temperatures from affecting the normal operation of the gears, and prevents the gears from having their lifespan shortened due to prolonged high temperatures, ensuring the stable and long-term operation of the reducer. At the same time, multiple glass observation windows can be cleaned synchronously via a linkage shaft and a cleaning plate, facilitating staff to observe the internal condition.

[0007] As a preferred embodiment, the bottom of the reducer housing is fixedly connected to a mounting base, and a sealing shell is provided on one side of the reducer housing.

[0008] As a preferred embodiment, the plurality of connecting plugs are respectively inserted into the sealing housing and the plurality of connecting plugs are respectively inserted into the reducer housing.

[0009] As a preferred embodiment, a precision gear reduction assembly is rotatably connected inside the reducer housing.

[0010] As a preferred embodiment, an input shaft is rotatably connected inside the reducer housing, and the input shaft is fixedly connected to a precision gear reduction assembly.

[0011] As a preferred embodiment, an output shaft is rotatably connected inside the reducer housing, and the output shaft is fixedly connected to a precision gear reduction assembly.

[0012] As a preferred embodiment, a limit sealing cover is fixedly connected to the other side surface of the reducer housing, and four glass observation windows are fixedly connected to the surface of the limit sealing cover.

[0013] As a preferred embodiment, a drive motor is fixedly connected to the surface of the limiting sealing cover.

[0014] As a preferred embodiment, the output end of the drive motor is fixedly connected to a drive gear, which rotates inside the limiting sealing cover.

[0015] As a preferred embodiment, the surface of the drive gear is engaged with an internal gear, which rotates inside the limiting seal cover.

[0016] By setting a limiting ring, the cooling fan driven by the combined shaft can be limited to prevent it from deviating during rotation, ensuring stable rotation and continuous, efficient airflow. In addition, the limiting seal can limit the driving gear, internal gear and driven gear in the transmission structure, and simultaneously isolate external impurities from entering, thus protecting the internal gears.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the setting of a transmission structure composed of a drive motor, a driving gear, an internal gear, and a driven gear, can synchronously drive multiple cooling fans to rotate inside the reducer housing via a combined shaft, accelerating internal air circulation and efficiently dissipating the heat generated by the precision gear reduction assembly. This effectively prevents high temperatures from affecting the normal operation of the gears, prevents the gears from having their lifespan shortened due to prolonged high temperatures, and ensures the stable and long-term operation of the reducer. At the same time, it can also synchronously clean multiple glass observation windows via a linkage shaft and a cleaning plate, facilitating staff to observe the internal condition.

[0018] This invention, by setting a limiting rotating ring, can limit the cooling fan driven by the combined shaft, prevent the fan from deviating during rotation, and ensure its stable rotation to continuously and efficiently accelerate air circulation; in addition, the limiting sealing cover can limit the driving gear, internal gear and driven gear in the transmission structure, and simultaneously isolate the intrusion of external impurities, thus playing a protective role for the internal gears.

The surfaces of the four linkage shafts 17 are fixedly connected to cleaning plates 18. The cleaning surfaces of the four cleaning plates 18 are in contact with the surfaces of the four glass observation windows 9. By setting a transmission structure consisting of a drive motor 10, a drive gear 11, an internal gear 12 and a driven gear 13, multiple cooling fans 16 can be synchronously driven to rotate inside the reducer housing 1 via a combination shaft 15.

In addition, the limiting seal cover 8 can limit the drive gear 11, internal gear 12 and driven gear 13 in the transmission structure, and simultaneously isolate external impurities from intrusion, thus playing a protective role for the internal gears.

[0033] Working principle and usage process of this utility model: In use, the reducer is first fixed with the mounting base 2, and the sealing shell 3 is sealed with the reducer shell 1 by the connecting bolt 4 to complete the assembly. After the external equipment is started, the input shaft 6 drives the precision gear reduction group 5 to rotate.
