A handling robot with one, in relation to a bottom plate or fundament (1) around a vertical axel (A), rotating frame (2) that supports an arm system (3, 5, 6, 7, 8) for a tool. The rotational movement is produced with a drive device (13) with a cog drive (16) that works together with a fixed cog wheel (12). The drive (13) is supported by an arm (17) that is pivotally housed in the frame (2) and is affected in toward the frame (2) by spring force that allows gap free motion between the cog wheel (12) and the cog drive (16). The cog drive (16) runs in a ring shaped channel (30) around the fixed cog wheel. This channel contains lubricant for lubricating the cog drive and the cog wheel.<IMAGE> |
