Analysis of Common Precision Reducer Technology for Industrial Robots

An industrial robot is a general-purpose machine equipped with a memory device and an end effect device that can perform various movements or processes instead of human labor. It is often used in production to replace some of the monotonous, frequent and repetitive long-term operations of workers, or in hazardous and harsh environments. It can improve the efficiency of production and the quality of products, and is an effective solution for enterprises to supplement and replace labor.

At present, the development of industrial robots is characterized by high speed, precision, compact body, multiple degrees of freedom and increased rigidity. The key areas also require heavy load or fast response. For example, most of the welding robots produced by automobile vehicles are between 150-300Kg, while the assembly robots in the electronics field need to respond quickly to accessories on the assembly line.

In the field of mechanical transmission, the reducer is an intermediate device between the power source and the actuator. Usually, the high-speed power of the motor, the internal combustion engine and the like are transmitted through the pinion gear on the input shaft to mesh the large gear on the output shaft to achieve the purpose of deceleration. And pass more torque. The currently proven and standardized reducers are: spur gear reducers, turbine reducers, planetary reducers, planetary gear reducers, RV reducers, cycloidal pin reducers and harmonic reducers. Since the 1980s and 1990s, in the development of emerging industries such as aerospace, robotics and medical devices, high-performance precision reducers with simple and compact structure, high transmission power, low noise and stable transmission are needed, among which RV reducer is harmonious. Wave reducers are two important reducers in precision reducers.

The RV reducer was developed on the basis of a cycloidal pinwheel transmission with a two-stage deceleration and a central disc support structure. Since it was put into the market in 1986, it has been the "master" reducer for robots because of its large transmission ratio, high transmission efficiency, high motion accuracy, low backlash, low vibration, high rigidity and high reliability.
