A disconnectable driving roller for roller conveyors having individual driving roller groups isolatable from a common conveyor drive comprising a driving wheel having a dog coupling for connecting the driving wheel to the roller, which includes a first axially slidable coupling; pivotally mounted coupling lever; and an axially slidable actuating disc between said coupling lever and the first coupling, with the coupling lever and the actuating disc having cooperating cams. The arrangement is such that when the coupling lever is moved from a disengaging to an engaging position, the cam disc is moved and in turn moves the first coupling into its position connecting the drive wheel to the roller. |
