On the afternoon of the 28th, an automatic welding robot equipped with a domestic RA reducer was undergoing tests at the Tianjin Seven High-tech Co., Ltd., and a one-meter-long robot arm, like a smart arm, was sometimes bent and turned over, and it was always accurate. Finding different welding points to make the welding effect more accurate... The reporter learned that the RV reducer, the core component of the industrial robot completely developed by the 707 China Shipbuilding Industry Co., Ltd., has undergone four months of uninterrupted testing, with excellent performance and even performance. Exceeding the level of imported similar products, the product will begin large-scale commercial use within the year. The success of this equipment has also cleared the biggest obstacle to the realization of complete domestic production of industrial robots in China. According to reports, China has become the largest consumer of industrial robots for five years in a row. In 2017, the output of industrial robots in the Chinese market reached 131,000 units, an increase of 81% year-on-year, among which the downstream robots and 3C industry have the greatest potential for industrial robots. However, the domestic industrial robot core technology, RV reducer, is mainly imported from Japan, which greatly restricts the manufacture and development of domestic industrial robots. Industrial robots can flexibly move in production, reliably complete process tasks, and ensure process quality, relying entirely on control systems such as retarders. The speed reducer is like the joint of the industrial robot. There are two kinds of speed reducers currently used in the robot field. One is the RV speed reducer and the other is the harmonic speed reducer. In an articulated robot, since the RV reducer has higher rigidity and rotation accuracy, the RV reducer is generally placed on a heavy load position such as a seat, a boom, or a shoulder, and the positioning accuracy and repeatability of the industrial robot are determined. Accuracy requirements are high. After four years of hard work, CSIC 707 finally developed an RV reducer, which is mainly used for industrial robots and wind power equipment such as welding and spraying. It is equipped with high-precision, small size and large torque characteristics, enabling the robot arm to The appearance of the structure is lighter in design, and achieves higher efficiency and longer service life, while increasing the reduction ratio also reduces vibration and start-up inertia.
