When talking about industrial robots, we must mention an important component, which is what we call the reducer. Because the working environment and performance of industrial robots are different, the types of reducers are also different. In this article, we will show the reducer commonly used in industrial robots. Industrial robots usually perform repetitive operations to complete the same process. In order to ensure that the industrial robot can reliably complete the actual task and quality, there is a high demand for the repeated positioning accuracy and the positioning accuracy of the proposed industrial robot during the operation process. Therefore, it is necessary to use a reducer to improve and ensure the accuracy of industrial robots. What kinds of reducers are commonly used in industrial robots? What are the advantages and disadvantages of each?
1. RV reducer
The reducer frame is a new type of transmission mechanism, which is based on the traditional rotary planetary pin gear. High efficiency has been widely used in industrial robot joints. The Servo engine power of the industrial robot is driven by the gear on the input shaft of the reducer, so that the output big tooth becomes the gear shaft, so as to achieve the purpose of speed reduction. The percentage of teeth and gears is the percentage of infection spread.
2. Harmonic reducer
Harmonic reducer is a new transition mechanism in reducer gears, which is usually used for industrial robots with minimum load. The usefulness of the model composed of elastic wheel and rigid wheel teeth number generator wave is slightly higher than that of the wheel flexibility. Harmonic reducer has significant driving advantages, small size, few parts, single engine 50-4000%, transmission efficiency 92-96%.
3. Planetary reducer
In short, the planets in the planetary reducer are the three wheels of the planet that revolves around the sun. The planetary reducer is a reducer function, also known as the planetary reducer, which can be used to reduce the engine speed. Industrial robot, improve torque.
Planetary working principle and reduction gear: when the sun rotates under the drive of the car, the participation of planetary wheels will make the planetary wheels rotate. At the same time, the other side of the planetary wheel works together with the inner ring and circular gear on the inner wall of the housing. The planetary wheel can rotate on the inner ring and circular gear along the rotation direction of the sun wheel in the driving force rotation frame, thus forming a revolutionary movement of the inner ring and circular gear. A wheel revolves around the sun.
