A vibrating roller is provided comprising a frame with a roller barrel mounted in the frame. The roller barrel includes first and second partial roller barrels, said first partial roller barrel including a central hollow shaft fixed thereto and extending axially therefrom. The second partial roller barrel is rotatingly mounted on said hollow shaft. A rotating unbalanced body is disposed in said hollow shaft for imparting vibratory motion to the first and second partial roller barrels. A prime mover is mounted on the frame, and drives the first and second partial roller barrels through a differential gear assembly. The differential gear assembly includes an externally toothed ring gear which is driven by a driving pinion which itself is drivingly connected to the prime mover. Connected to the externally toothed ring gear are a plurality of beveled pinion gears arranged to rotate about radial axes. First and second driven members of the differential gear assembly include first and second beveled ring gears, respectively. Said first and second beveled ring gears each mesh with said plurality of double pinion gears so that said first and second driven members are driven by the rotation of the externally toothed ring gear. The beveled pinion gears act as compensating gears allowing said first and second driven members to rotate at different speeds. The first driven member is connected to the hollow shaft of the first partial roller barrel by a first resilient force transmitting means. The second driven member is connected to the second partial roller barrel by a second resilient force transmitting means. At an end opposite said differential gear assembly, the hollow shaft is connected to a bearing structure which is in turn connected to the frame through a resilient mounting means. |
