industrial robots need a reducer

In recent years, industrial robots have ushered in explosive development, especially due to the increase in labor costs, making manufacturing companies increasingly favor the use of more mechanized, more efficient, and lower-cost robots. When it comes to robots, we have to mention one of the important components, the reducer, which is what we often call the reducer. Due to the different operating environments and performance of industrial robots, the types of reducers used are also different. So, do you know why an industrial robot needs a reducer?

The power source of an industrial robot is generally an AC servo motor. Because it is driven by a pulse signal, the servo motor itself can realize speed regulation.

Industrial robots usually perform repeated actions to complete the same process; in order to ensure that industrial robots can reliably complete process tasks in production and ensure process quality, the positioning accuracy and repeat positioning accuracy of industrial robots are very high. Therefore, to improve and ensure the accuracy of industrial robots, rv reducers or harmonic reducers are needed. Another role of precision geared motors in industrial robots is to transmit greater torque. When the load is large, it is not cost-effective to blindly increase the power of the servo motor. The output torque can be increased by a reducer within a suitable speed range.

In addition, the servo motor is prone to heat generation and low-frequency vibration under low-frequency operation, which is not conducive to ensuring accurate and reliable operation of industrial robots that work for a long time and periodically. The existence of the precision geared motor enables the servo motor to run at an appropriate speed, and accurately reduces the speed to the speed required by each part of the industrial robot, which improves the rigidity of the mechanical body while outputting greater torque. Compared with general-purpose reducers, robot joint gear motors are required to have the characteristics of short transmission chain, small size, high power, light weight and easy control. There are two main types of reducers widely used in articulated robots: rv reducers and harmonic reducers.

The reducers commonly used in industrial robots include RV reducers and harmonic reducers. Harmonic reducers are mainly used for light-loaded parts such as forearms, wrists, and hands. The RV reducer has a large transmission ratio range, relatively stable accuracy, high fatigue strength, and higher rigidity and torque carrying capacity.

In recent years, as the market for industrial and life assistance robots continues to expand, the demand for high-precision small modulus gears in precision reducers used in the joints of robots has also increased sharply. The robot-specific slewing ring (slewing bearing) products produced by Luoyang Hengguan have the advantages of light weight, high precision, reasonable price, and excellent service; our company has a professional production line for such products, which specializes in the production of such high-precision slewing bearings. It is also one of the main product series of our company. You are welcome to call for consultation and look forward to cooperating with you.
