[0003] Foreign brands of high-precision reducers for industrial robots include Japan’s Teijin RV reducer, Harmonic reducer, and Slovakia’s Spinea reducer, but they are expensive and have a long delivery cycle, and they are not easy to be adopted by domestic robots in mass production.
Patent No. CN103753529A discloses a gapless transmission mechanism for industrial robot joints. The mechanism uses double worms to eliminate the forward and reverse transmission gaps in the transmission chain and ensure the transmission accuracy, but the mechanism is relatively large

The invention discloses a backlash-adjustable internal meshing drum-shaped worm drive slow drive device. The backlash-adjustable internal meshing drum-shaped worm drive slow drive device comprises an outer rotor permanent magnet motor, a variable-tooth-thickness inner gear, a flange and a box body. The box body is in a cylindrical shape with one end open and the other end closed. The outer rotor permanent magnet motor is fixed into the box body through a height-adjustable support. The variable-tooth-thickness inner gear is arranged in the box body in a rotating mode. An outer rotor of the outer rotor permanent magnet motor is meshed with the variable-tooth-thickness inner gear to form a backlash-adjustable internal meshing drum-shaped worm drive pair. The flange is fixedly connected with the outer end face of the variable-tooth-thickness inner gear to close the opened end of the box body. The backlash-adjustable internal meshing drum-shaped worm drive slow drive device has the advantages of being fewer in part, high in reliability and accuracy, compact in structure, small in size, light in weight, adjustable in backlash, compensable in abrasion amount, and the like. The backlash-adjustable internal meshing drum-shaped worm drive slow drive device is suitable for precise heavy-duty drive occasions such as industrial robot joints which have limitation on sizes and weights.
Description
technical field [0001] The invention relates to a worm drive reduction device, in particular to an internal meshing drum-shaped worm drive slow drive device with adjustable side clearance for the intelligent joint of an industrial robot. Background technique [0002] Robotics is a forward-looking and strategic high-tech field, which is a high-tech integrated with multi-disciplinary advanced technologies such as machinery, electronics, computers, cybernetics, mechanisms, information and sensing, artificial intelligence, bionics, etc. industry. In recent years, robot technology research institutions and manufacturers in various countries have continued to explore in terms of technology deepening, introduction of new technologies, and expansion of application fields, and the development trend of foreign robotics fields is: continuous improvement in performance, continuous decline in price, and modularization of mechanical structures. (Such as the trinity modularization of serv...
