A robot joint arrangement having two joints, in which each joint is equip with an electric motor of its own and a reduction gear. To achieve a spacing as short as possible between the tilting axis (V) of the second joint and the flange surface for mounting the tool, the second joint is supported in a fork-like extension of the first joint.

Robot joint arrangement

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.

Robot joint

A robot joint includes an electric drive motor and step-down transmission ranged in a tubular inner part. The output of the step-down transmission is coupled to a tubular outer part coaxially surrounding the inner part. The outer part is guided on the inner part by bearings. The joint can be disassembled axially after screw connections holding the tubular parts together are loosened.
