Mechanical principle of 1. reducer

 

Deceleration transmission is a new transmission method. It is developed on the basis of traditional needle pendulum planetary transmission. It overcomes the shortcomings of general needle pendulum transmission. It also has small size, light weight, large transmission ratio range, long life, and precision. A series of advantages such as stable, high efficiency and stable transmission.

 

The importance of 2. reducer

 

The power source of the robot is generally AC servo motor, which is driven by pulse signal. The servo motor itself can realize speed regulation. The robot usually performs repeated actions to complete the same process. In order to ensure that the robot can reliably complete the process tasks in production and ensure the process quality, the positioning accuracy and repeated positioning accuracy of the robot are very high. In order to improve and ensure the accuracy of the robot, it is necessary to use RV reducer or harmonic reducer. Another role of precision reducers 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 through the reducer within the appropriate speed range. In addition, the servo motor is prone to heat and low-frequency vibration under low-frequency operation, which is not conducive to ensuring its accurate and reliable operation for industrial robots that work for a long time and periodically. The existence of precision reducer makes the servo motor run at a suitable speed, and accurately reduces the speed to the speed required by various parts of the industrial robot, and improves the rigidity of the mechanical body while outputting greater torque. Compared with the general reducer, the robot joint reducer is required to have the characteristics of short transmission chain, small size, high power, light weight and easy control.
