Precision reducer promotes robot industry
May 11, 2024
The reducer is the intermediate device between the power source and the actuator, usually the power of the motor and other high-speed operation through the input shaft of the pinion meshing the output shaft of the large gear to achieve the purpose of deceleration, and transfer greater torque, which is widely used in the automation equipment. For the robot, the reducer is an essential core component. Different from the reducer used in conventional automation equipment, the general robot will continue to perform repetitive actions in the work, so ie requires higher the positioning accuracy and repeated positioning accuracy. and the robot, especially compared with the large automation equipmen, the light robot is small and light. So as a core part, the reducer should also meet the requirements of lightweight.
At present, the reducers used in industrial robots are mainly: planetary reducers (cartesian coordinate robots), harmonic reducers and RV reducers (joint robots). As the name suggests, the planet rotates around the star, the planetary reducer has three planetary wheels rotating around a sun wheel, the planetary reducer is small , light, effective, durable, smooth and low in noise. It has the characteristics of power shunt and multi-tooth meshing, and is widely used in industry.
Driven by the development of the robot industry, domestic manufacturers have realized the importance of this part of the reducer and have also made continuous progress. In terms of harmonic reducers, domestic manufacturers such as green harmonic have gradually narrowed the gap with foreign products, and are constantly seeking breakthroughs in RV reducers. In recent years, the state has also introduced relevant policies to vigorously support this industry. It is believed that under the booming market environment and policy support, the rise of domestic reducer is just around the corner.
