1. Rotating drum containing a) at least one bearing ring (9) which is mounted coaxially on the outer surface of the drum casing and is supported on stationary bearing elements (10, 22), b) a ring gear (11) which is also arranged coaxially on the drum casing, is mounted directly on one end face of the bearing ring (9) and engages with at least one drive pinion (12, 12') of a rotating drum drive (13, 13'), c) a common housing (19) at least for the bearing elements (10, 22) of the bearing ring (9) and the rotating drum drive (13, 13'), characterised by the following features : d) the diameter of the ring gear (11) is greater than the diameter of the bearing ring ; e) the ring gear has a T-shaped cross-section consisting of a radially extending stem (11a) and a peripheral flange (11c) which is provided with teeth (11b) ; f) the ring gear (11) is constructed as an undivided ring and is mounted with its radially inwardly directed stem (11a) on a radial flange (9b) which projects radially outwards on the axially outer end of the bearing ring (9) and has a greater diameter than the bearing ring (9). |
