A weak link-industrial robot bearing


As one of the key basic components of industrial robot, industrial robot bearing is still a relatively weak link in China. Its localization is related to the overall competitiveness of domestic robot industry. In order to meet the needs of the development of domestic robot industry, it is urgent to carry out the research and development of industrial robot supporting bearing and the key technology of industrialization, so as to reduce the production cost on the premise that all the performance indexes of the bearing are up to the international advanced level, so that it further improved the industrial system of industrial robots. The development of modern industrial robots tends to be lightweight. To install bearings in limited space, they must be small in size, light in weight. But at the same time, the robot has high load, high rotation precision, high running stability, high positioning speed, high repeatable positioning precision, long life, high reliability, so the supporting robot bearing must have high bearing capacity and high precision, high stiffness, low friction torque, long life, high reliability performance. Lightweight and high performance are a pair of contradictions.
