Industrial robot comprising a base (1), a pedestal (2) supporting a robot arm (3) and being rotatably mounted on the base (1) by means of a bearing (4), a gear unit, mounted practically without backlash on the pedestal (2), and a motor, mounted on the pedestal (2) and being connected to the drive shaft of said gear unit. According to the invention the output shaft (6) of the gear unit is arranged with its axis of rotation approximately coinciding with the axis of rotation of the bearing (4), and the output shaft (6) is connected to the base (1) by means of a tangentially rigid but otherwise flexible shaft coupling, preferably in the form of a plate coupling (8). |
