Classification of reducer
In the gear transmission industry, the reducer is the intermediate device that connects the power unit and the electric actuator. Generally, it reduces the driving force of the motor, gas turbine and other high-speed operation according to the pinion on the input shaft to mesh with the transmission wheel on the output shaft. Faster destination, and transmit a larger torque.
At this stage, the perfect and standardized reducers are: cylindrical gear reducer, turbocharged reducer, planetary reducer, large planetary gear reducer, RV reducer, cycloid reducer reducer and harmonic reducer.
Under the requirements of the development trend of new industries such as aerospace, intelligent robots and medical machinery, it is necessary to construct a simple and compact, high transmission output power, low noise, and stable transmission system performance and excellent high-precision reducer, in which cycloid RV gear Reducer and harmonic reducer are the key two types of reducers in high-precision reducers.
Features of precision cycloidal pinwheel RV gear reducer
The precision cycloidal pinwheel RV gear reducer is based on the basic development trend of the cycloidal pin reducer transmission system. It has a two-stage speed reduction due to its large reduction ratio, high efficiency of the transmission system, high precision of movement, and small backlash. The advantages of low vibration, high rigidity, and reliability are the "dedicated" reducers for intelligent robots.
Definition of precision cycloidal pinwheel RV gear reducer
The precision cycloidal pinwheel RV gear reducer is composed of a front stage of a planetary gear reducer and a rear stage of a cycloidal pinwheel reducer. The precision cycloidal pinwheel RV gear reducer has a compact structure, a large transmission ratio and a certain Transmission machinery with self-locking function under conditions.
The precision cycloid RV gear transmission is developed on the basis of the traditional pendulum planetary transmission. It not only overcomes the shortcomings of the general pendulum transmission, but also has high precision (backlash less than 1 arc minute), high rigidity, high durability, A series of advantages such as high output density (strong torque & compactness), large reduction ratio range and low vibration.
The importance of precision cycloidal pinwheel RV gear reducer to industrial robots
The J1-J4 joints of industrial robots generally use precision cycloidal pinwheel RV gear reducers. The J5-J6 joints of light-duty industrial robots may use a harmonic reducer with a small load. An industrial robot uses an average of 4.5 cycloid RV reducers.
The power source of the industrial robot is an AC servo motor. In order to ensure that the robot can reliably complete the task and ensure the quality of the process, the repeated positioning accuracy of the robot is very high. This index needs to rely on high-precision cycloid RV gear reducer to complete. Another function of the cycloid RV gear reducer is to reduce speed and increase torque. When the load is large, it is not advisable to continuously increase the motor power. At this time, the best shortcut is to increase the output torque through the cycloid RV gear reducer.
In addition, the motor is prone to heat and low-frequency vibration under low-frequency operation, which is not conducive to ensuring the accuracy and reliability of the robot. The cycloid RV gear reducer can make the motor run at an appropriate speed, and accurately reduce the speed to the speed required by each part of the industrial robot, while improving the rigidity of the mechanical body, while outputting more torque.
The innovation of robotics is changing with each passing day. Among them, the rapid development of industrial robots is inseparable from the continuous improvement of its core component technology. One of the most critical core components in industrial robots is the precision cycloidal pinwheel RV gear reducer.
China's precision cycloidal pinwheel RV gear reducer has undergone more than 30 years of development. With the development of my country's industrial robot industry, the technology has matured.
