ABSTRACT:
A robot joint includes an electric drive motor and step-down transmission ilt into the robot joint housing. The output of the transmission drives a gear to which a mounting flange is coupled. A first part of the robot is coupled to the housing and a second robot part is coupled to the mounting flange. The mounting flange is supported axially and radially in the housing by bearings. The bearings preferably include a conical-roller bearing for providing radial and axial support and a needle bearing for providing axial support. Both bearings are maintained under pretension by a spring, thereby providing a robot joint which is free of play.
