UNITA' DI SUPPORTO PER UN TAMBURO MESCOLATORE, IN PARTICOLARE DI UNA BETONIERA PER CALCESTRUZZO PRESONFEZIONATO

摘要

The invention relates to a bearing unit (7) for a mixing drum of a ready-mix concrete mixer. The bearing unit (7) is distinguished by the fact that the tumbling movements of the mixing drum and the radial bearing arrangement are considered separately. To this end, the bearing unit (7) has two tapered roller bearings (9, 10) with a common outer ring (11). The outside diameter of the outer ring (11) is formed spherically and guided in outer shells (13, 14).
