Compared with cylindrical gear reducer transmission, planetary gear reducer transmission has many unique advantages. Its most significant feature is that it can split power when transmitting power; at the same time, its input shaft and output shaft are coaxial, that is, the output shaft and the input shaft are both set on the same main axis. Therefore, planetary gear reducer transmission is now used to replace ordinary gear transmission, and as a speed increaser and transmission device in various mechanical transmission systems. ...
Planetary gear reducers are mainly composed of sun gears, planet gears, and internal gears. They have a simple structure and high transmission efficiency, and are often installed on servo motors to reduce speed, increase torque, and achieve precise positioning. They are widely used in CNC machine tools, industrial robots, service robots, manipulators, food machinery, packaging machinery, laser cutting machines, woodworking engraving machines, printing machinery, injection molding machinery, photovoltaic equipment, lithium battery equipment, and other mechanical equipment....
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....
The harmonic speed reducer is a transmission device mainly used for reducing speed. It generally has a small size and high precision, and is now widely used in various industrial fields. However, the speed reducer often experiences oil leakage during use. Let's briefly analyze the reasons for oil leakage in the harmonic speed reducer....
Today, let's talk about the relationship between harmonic drive and cycloidal gear reducer. We've already discussed a lot about the differences between them. For example, the size of the cycloidal gear reducer is the same as the harmonic drive, but its lifespan and rigidity are more than three times higher, and it has a larger load capacity. Another point is that when the motor speed reaches 300-600 rpm, the harmonic drive is prone to shaking due to poor rigidity, while the cycloidal gear reducer is very stable and won't have any issues....
When it comes to harmonic drive, those familiar with it know that it has advantages such as high precision, high torque, high rigidity, and high transmission efficiency compared to other reducers. Little do they know that its working principle also determines that it has many shortcomings alongside these advantages. The advantages and disadvantages of it have been verified by industry experts and scholars in the early stage. However, the scientific nature of the harmonic gear transmission principle surpasses other reducer products....
Harmonic drive is an essential power device among many mechanical equipment, because of its extremely high precision, especially suitable for cutting-edge fields that require precise motion control. But harmonic drive has a big downside, it has a short lifespan and is not durable. So, is there any gearbox that can replace the harmonic drive?
...
Due to the numerous advantages of harmonic gear reducers, they have rapidly extended into fields such as energy, communications, machine tools, and automobiles in recent years. In daily use, it has been concluded that they exhibit excellent performance, whether in highly sensitive tracking systems or in transmitting high torque power....
In the automation industry, planetary gear reducers are the second most commonly used general mechanical equipment, so it's very important to choose the right one. Choosing the right gear reducer can provide a larger torque, allowing for optimal speed and better performance, reducing the inertia of the load, and increasing equipment stability. In addition to meeting the requirements, economic considerations should also be taken into account. In other words, the technical indicators of the planetary gear reducer should not only meet the requirements of the equipment, but also save costs.
