When discussing industrial robots, we must mention a crucial component: the reducer. Due to the varying working environments and performance requirements of industrial robots, different types of reducers are used. In this article, we will showcase commonly used reducers in industrial robots. Industrial robots typically perform repetitive operations to complete the same processes. To ensure that industrial robots can reliably complete actual tasks and maintain quality during operation, the requirements for repeatability and positioning accuracy are high. Therefore, it is necessary to use reducers to improve and ensure the accuracy of industrial robots. What are the commonly used reducers for industrial robots? What are their respective advantages and disadvantages?
Reducers commonly used in industrial robots
1. RV reducer
The reducer frame is a new type of transmission mechanism based on the traditional rotating planetary gear pinion. Its high efficiency has been widely applied to industrial robot joints. The Servo motor power of the industrial robot is supplied by the gear on the reducer's input shaft, making the large teeth at the output shaft the gear shaft, thus achieving speed reduction. The percentage of teeth and gears corresponds to the percentage of infection transmission.
2. Harmonic reducer
Harmonic reducers are a new type of transition mechanism in reducer gears, typically used in industrial robots with minimal loads. The model consisting of a generator wave of teeth on both flexible and rigid wheels is slightly more useful than the flexibility of a single wheel. Harmonic reducers offer significant driving advantages: small size, fewer parts, single-engine efficiency of 50-4000%, and transmission efficiency of 92-96%.
3. Planetary gear reducer
In short, the planets in a planetary reducer are three wheels of planets orbiting the sun. A planetary reducer is a type of speed reducer, also known as a planetary gearbox, used to reduce engine speed and increase torque in industrial robots.
The working principle of planetary gears and the reduction of gears: As the sun rotates under the drive of a car, the participation of planetary wheels will cause the planetary wheels to rotate. Simultaneously, the other side of the planetary wheels works with the inner ring and circular gears on the inner wall of the outer shell. The planetary wheels can rotate along the direction of rotation of the sun wheel within the driving force rotation frame on the inner ring and circular gears, thus forming a revolutionary motion of the inner ring and circular gears. What revolves around the sun is a wheel.
What are the common types of reducers used in industrial robots? What are their advantages and disadvantages? What types of gears do industrial robots typically use? RV reducers. Harmonic reducers (planetary) allow the Servo engine to operate at the appropriate speed, reducing the speed to the required speed for each component of the industrial robot while increasing the generated torque.
