Abstract:
A roller conveyor comprising:a) a plurality of side wings spaced apart from each other; b) a plurality of rollers successively arranged between said plurality of side wings in the direction of conveyance wherein at least one of said plurality of rollers is a driven roller; c) at least one motor disposed on one of said plurality of side wings outside the roller conveyor and connected to said at least one driven roller; d) at least one gearing connecting said at least one motor to said at least one driven roller; e) a plurality of trunnions extending within said plurality of rollers on their face sides, said plurality of trunnions supporting said plurality of rollers within said plurality of side wings wherein at least one trunnion is designed as an output shaft of said gearing and supports said at least one driven roller by projecting into said driven roller at a face end and connects with torsional strength with said at least one driven roller; and f) at least one coupling serving as a driving connection between said at least one gearing and said at least one driven roller wherein said coupling compensates for both angular and axial errors of said plurality of rollers.
