The structure of the planetary gear reducer

 The planetary gear reducer is a key component in various mechanical systems, providing torque amplification and speed reduction in a compact design. Its unique structure consists of several meshing gears that operate in a planetary motion around a central sun gear. This intricate arrangement allows for efficient power transmission and ensures smooth operation within a limited space.

At the heart of the planetary gear reducer is the sun gear, which is usually positioned in the center. It meshes with multiple planet gears arranged in a circular formation around it. These planet gears are connected to a carrier arm, which allows them to rotate as a group. Finally, an outer ring gear surrounds the entire assembly, completing the gear system. The teeth of the gears are precisely shaped to ensure smooth engagement and proper power transmission.

The planetary gear reducer operates through a fascinating combination of rotational and translational motion. When the input torque is applied to the sun gear, the planet gears rotate around it while also revolving around the carrier arm. This results in a combined motion called epicyclic motion. The rotation of the planet gears is constrained by the outer ring gear, which causes them to drive the output shaft in a reduced speed or amplified torque, depending on the configuration.

In conclusion, the structure of the planetary gear reducer is a sophisticated arrangement of gears that enables efficient power transmission in a compact design. Its unique configuration involving the sun gear, planet gears, carrier arm, and outer ring gear allows for a combination of rotational and translational motion. This gear system is widely used in various mechanical applications, from automotive transmissions to industrial machinery, proving its reliability and efficiency. Studying and understanding the structure of the planetary gear reducer provides valuable insights into the principles of mechanical engineering and its applications in real-world systems.

Common Types of Reducers Used in Industrial Robots

In industrial robotics, there are several commonly used types of reducers:

1. RV Reducer

The RV reducer mechanism is a novel transmission mechanism based on the traditional rotating planetary wheel pinion gear. It is widely applied in the joints of industrial robots due to its high efficiency. The power of the Servo engine in industrial robots is transmitted through gears on the input shaft of the reducer, resulting in a reduction in speed. The ratio of teeth and gears determines the percentage of transmission efficiency.

2. Harmonic Reducer

The harmonic reducer is a new transitional mechanism in the gear system and is typically used in industrial robots with minimal loads. It consists of elastic and rigid wheel gear generators, offering slightly higher utility than flexible wheel systems. The harmonic reducer exhibits significant driving advantages, such as compact size, fewer components, a single engine range of 50-4000%, and a transmission efficiency of 92-96%.

3. Planetary Reducer

In simple terms, the planets in the planetary reducer revolve around the sun, much like the planets in our solar system. The planetary reducer, also known as a planetary gear system, functions as a reducer to lower the rotational speed of the engine, thereby increasing torque in industrial robots.

The working principle of the planetary reducer involves reducing gears. When the sun rotates under the driving force, the engagement of the planetary wheels causes them to rotate. Simultaneously, the other side of the planetary wheels works together with the internal ring and circular gears on the inner wall of the housing, allowing the planetary wheels to rotate in the same direction as the driving frame along the sun wheel's rotation direction within the driving force. This creates a revolution motion of the internal ring and circular gears. The wheel revolving around the sun represents one revolution.​

 Industrial robots typically use RV reducers, harmonic reducers, and planetary reducers. RV reducers offer suitable speed control for Servo engines, reducing the speed to the desired level for each component of the industrial robot while increasing the generated torque.

How to Deal with Heating Issues in Harmonic Reducers

 The harmonic speed reducer plays an important role in the operation of mechanical equipment. Due to its small size, light weight, and high-precision reduction effect, it is widely used by many manufacturers of mechanical equipment.

 

As a reduction tool, the harmonic speed reducer is bound to encounter some problems after prolonged use, such as heating issues. Today, I'm going to share some knowledge about how to deal with the heating of harmonic speed reducers.
 
Generally, there are two main reasons for the heating of the speed reducer. One is related to problems with the eccentric bearings, and the other is related to lubricating oil. Of course, there are other issues as well, such as improper installation of new machines. These two are relatively common situations. Now, let's discuss how to identify and solve these problems.
 
When we notice that the harmonic speed reducer is heating up, we can start by checking the lubricating oil to see if the machine is running low on it. If there's insufficient or dried-up lubricating oil, we can add the appropriate amount.
 
If even after adding lubricating oil, the temperature of the harmonic speed reducer doesn't decrease, then it's not an issue with the lubricating oil. In that case, we need to continue troubleshooting. Next, we can look at the duration of machine operation, as prolonged continuous operation and overload can lead to heating, which is a normal occurrence. The solution to this problem is simple—just shut down the machine for a period of time.
 
Another aspect to consider is whether the installation of the harmonic speed reducer and the machine is appropriate. Inappropriate installation can also lead to heating issues. This problem is similar to the problem of eccentric bearings in the harmonic speed reducer and requires a certain level of technical expertise to identify. If you're not familiar with this, it's advisable to seek assistance from the speed reducer manufacturer for testing.
 
Once the problem is identified, solving it becomes straightforward. For those not well-versed in speed reducers, after checking the lubricating oil and prolonged operation, if the issue persists, seeking help from a professional harmonic speed reducer manufacturer would be beneficial for quickly resolving the problem and avoiding any potential major issues.
