<p>A low load wrist transmission mechanism for an industrial robot comprises a wrist base (12), a J5 shaft input gear shaft (1), a J6 shaft input gear shaft (11), a J5 shaft output end (13), a J6 shaft output shaft (7), a J5 shaft large speed ratio hypoid gear I (3), a J5 shaft large speed ratio hypoid gear II (6), a J6 shaft large speed ratio hypoid gear I (4), and a J6 shaft large speed ratio hypoid gear II (5). The J5 shaft input gear shaft (1) and the J6 shaft input gear shaft (11) transfer power to the J5 shaft output end (13) and the J6 shaft output shaft (7) through a large speed ratio hypoid gear mechanism, respectively. In the wrist transmission mechanism, a large speed ratio hypoid gear drive reducing device is used to replace the transmission of a harmonic reductor, thus the structure is simple, the cost is low, the motion is accurate and reliable, and the manufacturing cost of a robot is reduced.</p> |
