What is an Industrial Planetary Gearbox for Use?

 

In the industrial sector, gears are the most important and indispensable basic component. Planetary gears are at the heart of modern engineering; what is industrial planetary gearbox for use? they are the gearboxes that power everything from basic factory machinery to cutting-edge electric automobiles. Simple arrangements of central drive and orbital gears were invented thousands of years ago to approximate the motion of the planets. Today, engineers utilize planetary gears in applications that require great torque density, operating efficiency, and longevity.

What is planetary gears?

The planetary gear is a gear system that consists of four components: a sun wheel, many planetary gears, an internal gear, and a planetary carrier that connects the planetary gears. It has an extremely complex structure, making it difficult to design or construct; it can attain large reduction ratios by gearing.

What is a planetary gearbox?

The fundamental transmission structure of the planetary gearbox is the planetary wheel, sun wheel, inner gear ring, drive motor, and drive shaft.The planetary gearbox can be separated into three pieces from the appearance: the input section, reduction section, and output section.

Input section: The input section refers to the end connected to the motor. Including the input shaft hole, the input flange reduction section refers to the core section of the gearbox, which looks like a box from the outside, but actually contains numerous core components, such as planetary gears, and sun gears, and an internal gear ring.

Output section: The output section refers to the end connected to the equipment, including the output shaft and output flange.

 

What does a planetary gearbox do?

 

Planetary gearbox provide the capacity to readily change ratios. Known for their high ratio potential, compact design, and resilience, planetary gears are more adaptable than other gears because planetary gear drives have the capacity to readily alter ratios.

Planetary gears are used in internal combustion engines, electric motors, or hydraulic motors for their dependability, performance, and capacity to bear large torque loads. The input gear is usually the central gear of a planetary gear. Two or three planetary gears rotate around it in an outer ring and are connected to the output shaft via a gear carrier.

The planetary gearbox is an extensively used reduction device. The precision of the planetary gearbox is very high, and to ensure precise transmission, the planetary gearbox is generally used to reduce the speed to increase the torque and reduce the load.

The principle of the planetary gearbox is a power transmission mechanism that uses the speed converter of gears to reduce the number of rotations of the motor to the desired number of rotations and to generate a larger torque. The gears with fewer teeth on the drive shaft of the planetary reducer mesh with the bigger gears on the output shaft to fulfill the aim of slowing. The ordinary reducer will also have numerous pairs of the same principle of gear meshing to achieve the necessary reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

The planetary gearbox adopts involute planetary gear transmission, rational use of internal and external meshing, and power shunt; the box body adopts ductile iron, greatly improving the steel and vibration resistance of the box; gears are carbonized quenched treatment, to get a high hard wear-resistant surface, gears after heat treatment all grinding teeth, reduce the noise, improve the efficiency and service life of the machine; planetary gearbox planetary transmission stages have 2 and 3 stages, which is the most This is the most frequent number of steps.

 

Planetary Gearbox Benefits

Planetary gearbox because of its small size, lightweight, high load-bearing capacity, long service life, smooth operation, low noise, high output torque, high-speed ratio, high efficiency, and performance safety characteristics. It also has the properties of a power shunt and multiple teeth meshing for unique utilization. The transmission efficiency of the planetary gearbox is normally above 90 percent, can reach greater than 95 percent, and is frequently employed.

The Future Trend of Industrial Gearbox 

Electrification, adaptability, intelligence, and lightweight are the future product trends, which is both a challenge and an opportunity for traditional gear firms.

Electrification: The electrification of power makes the traditional gear transmission face challenges, and the crisis it brings is that the traditional gear transmission, on the one hand, to a simpler and lighter structure of high speed, low noise, high efficiency, high precision, and long life upgrade, on the other hand, is facing the electric direct drive without gear transmission subversion. Therefore, traditional gear transmission companies should not only study how to meet the requirements of electrification of ultra-high-speed ( 15000rpm) gear transmission noise control, to seize the current explosive growth of electric vehicles and give rise to the growth of new transmission opportunities but also pay great attention to the future of gearless electric direct drive technology and electromagnetic drive technology on the traditional gear transmission and gear industry to bring the revolutionary threat.

 

Future market competition is becoming increasingly stimulating. The demand for products tends to diversify and personalize, but the demand for individual products is not necessarily very large, and the gear industry, as a basic industry in the manufacturing industry, faces many downstream areas where the diversity of product manufacturing and efficiency put forward higher requirements. Therefore, it is necessary for enterprises to establish a flexible production system, in the same production line through the adjustment of equipment to complete the mass production of different varieties of tasks, not only to meet the diversified requirements of multiple varieties but also to minimize the downtime of the equipment line, to achieve flexible production, and to build the core competitiveness of enterprises.

 

Intelligent: the wide use of control technology in the machine, so that the machine can achieve automation; control technology; information and communication technology; and the integrated application of network technology so that the machine and manufacturing are intelligent. For traditional gear manufacturing firms, the difficulty is how to merge electrical engineering, electronic engineering, control technology, network technology, and develop intelligence.

 

Lightweight: lightweight and high-strength materials, structural weight reduction and surface modification and strengthening, necessitating cross-industry cooperation and advanced simulation technologies.
