What Is Planetary Reducer

Planetary reducers are compact components that strive to maximize the transmission of torque in various applications. The mechanisms ensure the transmission of high torque levels while simultaneously decreasing the required number of motor revolutions for a set level of power. The reducers are composed of a gearbox and aligned input and output shafts. Industrial automation systems, including dc transmission, servo, and stepping systems, use planetary reducers to efficiently manage tasks that demand high levels of torque.

Advantages of Planetary Reducer

Compact size and low weight
Compared to similar gear reducer systems, these components weigh less and have a compact design that can fit in more designs. Planetary reducers can maintain the same torque output while decreasing up to 50% in size.

Durability and long life
These gear reducers have ball bearings that help the components operate smoothly and efficiently. This reduces wear throughout their operational lifespan, leading to less damage and long product life.

Increased repeatability
Planetary reducers offer higher axial load speeds and radial load speeds than comparable systems. This increases their overall reliability and sturdiness and decreases the potential for misalignment. These features allow planetary reducers to mitigate the effects of vibration and ensure consistent transmission over time.

Increased torque transmission
Planetary reducers are built for maximum teeth engagement. Because more teeth are in contact, it can both handle more torque and transfer more torque.

Versatility
Each stage of a planetary reducer system can be stacked or modified for custom configurations that meet the needs of a given application. Planetary reducers are also easy to work with: Once they're installed in a cylindrical gearbox, the gear reducers can be installed almost anywhere.

How Does Planetary Reducer Work?

A planetary reducer is made of a central sun gear, an outer ring, a carrier, and the planetary gears. The sun gear is located at the center of the assembly and meshes with the teeth of the planet's gears. It receives the input for the gear set and is known as the main gear in a planetary gear set. Planetary gears can rotate around the sun gear. Planetary gears have one or more planet gears and control the speed of the transmission of power. However, a carrier keeps the planetary gears in their basic form and sets their gaps. It rotates with the planetary gear. Planetary gears are used in gearboxes widely, planetary reducers can offer the engine from basic plant devices to cutting-edge electric systems. Having several teeth to share the load also permits planetary parts to transfer high levels of torque. Large speed reduction, compact size, and high torque transmission make planetary reduceres become a common industrial choice.

The Difference Between Planetary Reducer And Gear Gearbox

The working principle is different
Planetary reducer: The motor is directly connected, and the sun gear drives the planetary gears on the planetary gear carrier. The entire planetary gear system rotates along the inner gear ring while revolving, and the planetary gear carrier is connected to the output shaft to achieve the purpose of deceleration. The working principle is similar to the gear reducer, but it has two characteristics of "power splitting" and "multi-tooth meshing" that the gear reducer cannot achieve. These two features are often used in transmissions and clutches. In addition, the planetary reducer is a military product in the field of reducers, but the price is industrial, and it is widely used in industrial equipment manufacturing.
Gear reducer: The use of gear transmission at all levels is used to reduce the speed. For example, the small gear can drive the large gear to achieve a certain reduction ratio. The motor provides the rotational speed, and the drive shaft connects the motor and the gear reducer. The more gear stages of the reducer, the slower the speed, the greater the torque, and the stronger the bearing capacity. The disadvantage is that the noise will be relatively large. When designing the gear reducer, the power demand mode is basically customized, that is, the parameters such as the speed and torque of the gear reducer are customized according to the needs.

The structure is different
Planetary reducer: Planetary reducer is an extension and optimization of gear reducer. The main transmission structure of the planetary reducer consists of a sun gear, a planetary gear, an inner gear ring, a planet carrier, a sealing ring and a transmission bearing. Compared with the gear reducer, its manufacturing process is more complicated, the performance is better, and the transmission is more reliable.
Gear reducer: A combination of a geared motor and a large reducer, including the prime mover and working device gears. The external main structure of the gear reducer is composed of a drive shaft, a spur gear and a motor; the internal structure is mainly composed of multi-stage gears, which is simpler in structure than the planetary reducer. Each gear is driven by multiple gears of different sizes, thereby forming a reduction ratio and at the same time, the output speed is also reduced, and the torque is increased to achieve the ideal driving effect.

Different uses
Planetary reducer: It can be used as a supporting component in industries such as robot, laser cutting, printing, lithium battery, coating machine, packaging, manipulator, etc. It is also widely used in automobile, communication, mechanical equipment, electronic products, medical machinery and other fields.
Gear reducer: Widely used in large-scale mining, steel, chemical, port, environmental protection and other fields.

The characteristics are different
Planetary reducer: With high rigidity, high precision, high transmission efficiency and a wide range of optional transmission ratios. Small size, light weight, high bearing capacity, long service life, stable operation, low noise and large output torque. It can realize power split and multi-tooth meshing. Material and machining accuracy, high production cost.
Gear reducer: No cooling, maintenance-free grease, long service life and high output efficiency; the shell is made of alloy steel, with high coaxiality and good dynamic balance, and can be installed on various machining center machine tools. Accuracy and torque are lower than planetary reducers.

How to Select Planetary Reducer ?

Planetary reducer is a commonly used transmission device and is widely used in various mechanical equipment in industrial production. Several factors need to be considered when selecting a planetary reducer, including working conditions, transmission ratio, output torque, accuracy requirements, etc. Below I will introduce in detail how to select a planetary reducer.

Working conditions
The first thing to consider is the working conditions of the planetary reducer, including working environment temperature, workload, working time, etc. Different working conditions require the selection of different planetary reducer models and materials to ensure that it can operate normally in a specific working environment.

Transmission ratio
The transmission ratio refers to the speed ratio of the input shaft and the output shaft, usually expressed by the reduction ratio. When selecting, you need to select the appropriate planetary reducer model based on the actual transmission ratio requirements to ensure that the output speed meets the requirements.

Output torque
Output torque refers to the torque that the output shaft of the planetary reducer can provide. It is necessary to select the appropriate model and specification of the planetary reducer according to the actual load requirements to ensure that it can provide sufficient output torque.

Accuracy requirements
In some applications that require higher transmission accuracy, it is necessary to choose a planetary reducer with higher precision to ensure the stability and reliability of the transmission system.

Durability and reliability
When selecting, you need to consider the durability and reliability of the planetary reducer, and choose products with good quality and long life to ensure long-term stable operation of the equipment.

Installation method
Select the appropriate planetary reducer model and structure according to the actual installation space and method to ensure that it can be easily installed and maintained.

Brands and suppliers
When selecting, you need to choose brands and suppliers with a certain degree of popularity and credibility to ensure product quality and after-sales service. Like our sinbad coreless motor company , specializing in the production of low noise , high efficiency , long life.

How To Lubricate The Planetary Reducer

Planetary reducers are maintenance-free, and the grease inside usually does not require maintenance. The matters needing attention for the replacement of planetary gear reducer oil are as follows:

After 300 to 400 hours of oil change of the reducer, the lubricant should be changed, and then the lubricant should be changed every 1500 to 2000 hours. In the harsh working environment, temperature, and dust, the lubricant should be checked every half month, and the lubricant should be cleaned to replace the lubricant to keep the lubricant clean and extend the life of the reducer,improve economic efficiency.
When changing the oil, wait for the reducer to cool without danger of burning, but still keep it warm, because the viscosity of the oil increases after cooling and it is difficult to drain the oil. The output rotation direction is the same as the input rotation direction. The series is irrelevant. Both deceleration and speed-increasing gearboxes can be called reducers (reducers or gearboxes). Reducers are divided into first, second, and third stages according to the number of decelerations. Two-stage planetary reducer means that the reducer has two speed reductions Increased speed), and the two sets of planets contain two sun gears, two planetary carriers, two internal ring gears, two sets of planetary gears (3 or 4 each set) to see the series. Planetary level is about 97~98%, parallel axis level is about 98~99.5%. The efficiency of planetary gear reducers is not necessarily higher than that of parallel gear reducers, mainly because planets can be small.

Then the analysis of the factors causing the return error of the accuracy of the planetary reducer is as follows:
Assembly error: The errors that occur when assembling the various components of the planetary reducer mainly include the installation errors between the shaft and the bearing, the gear and the shaft, and the box body. Points to consider during the installation process. Second, the inherent error: the primary origin of the gear return error is the error from the gear machining process. Gear tooth thickness, tooth width, tooth shape, etc., such processing errors can not be prevented, only to minimize this error.

Errors of other environmental physical factors: During the operation of the planetary reducer, errors due to the rise of temperature and the elastic deformation of the body itself can be prevented by adopting relevant methods.

Application and Maintenance of Planetary Reducer

It has the advantages of compact structure, high transmission efficiency and strong bearing capacity, but it also needs to pay attention to some matters in the process of use to ensure its normal operation and prolong its service life. This paper will introduce the matters needing attention in the use of planetary reducer to help readers better understand and apply the device.

Correctly install the planetary reducer
Read the product manual carefully before installation to understand the installation requirements and steps. Ensure that the installation foundation is firm and avoid vibration and resonance. Pay attention to axial and radial alignment during installation to reduce unnecessary friction and wear.

The rational selection of planetary reducer
According to the actual working conditions and load requirements, choose the appropriate planetary reducer model and specifications. Pay attention to the selection of reduction ratio to meet the required output speed and torque requirements. Considering environmental factors, such as temperature and humidity, choose the appropriate protection level.

The correct use of planetary reducer
Before starting, check the oil level and quality of lubricating oil to ensure adequacy and cleanliness. When starting, speed should be increased slowly to avoid sudden impact and overload. Avoid overloading for a long time, so as not to damage the planetary reducer. Regularly check the working state of the planetary reducer, such as noise and temperature, and find problems in time and carry out maintenance.

The maintenance of the planetary reducer
Change the lubricating oil regularly, keep the oil clean, and maintain it according to the specified lubrication cycle. Clean the surface of the planetary reducer to prevent dust and impurities from entering the interior. Regularly check the fastening of fasteners to ensure reliable connection. Pay attention to damp-proof and rust-proof, so as to avoid damp and rust of planetary reducer.

Troubleshooting and maintenance
When abnormal noise and temperature rise are found, stop the machine immediately for inspection. If a fault is found, contact personnel for maintenance in time to avoid disassembly and repair by yourself.
As an important transmission device, the precautions of planetary reducer have an important influence on the normal operation and life of equipment. Through correct installation, reasonable selection, correct use and regular maintenance, the performance and reliability of planetary reducer can be guaranteed. It is hoped that the precautions described in this paper can help readers to better apply planetary reducers and improve the working efficiency and service life of equipment.
