The invention relates to a power transmission and bearing arrangement for a drum, the drum (1) being provided for a rope (2) that exerts a tangential force on the circumference of the drum, and the arrangement comprising the mounting of the drum in bearings (7 to 10) to a frame structure (6) and a drive arrangement for rotating the drum, the drive arrangement comprising at least one member (3) that is in drive engagement with the drum surface. To simplify the structure and to eliminate the bending moment acting on the drum, the drum bearing arrangement comprises means (7 to 10) that carry the drum and support the drum surface (1) to the frame structure (6) directly from the outer and inner surfaces (4, 5) of the drum surface, the point where the rope is unwound from the drum being located within the bearing area when seen from the end of the drum.
A power transmission and bearing arrangement for a drum, the drum being meant for a lifting rope of a lifting apparatus, the rope exerting a tangential force on the circumference of the drum, and the arrangement comprising the mounting of the drum in bearings to a frame structure and a drive arrangement for rotating the drum, the drive arrangement comprising at least one means which is in drive engagement with the drum surface, and the drum bearing arrangement comprising means carrying the drum and supporting the drum surface directly to the frame structure on the inner and outer surfaces of the drum, wherein the means in drive engagement is substantially located, when seen in the circumferential direction of the drum surface, in an area on the other side of the drum surface between the means arranged to support and carry the drum surface, or substantially located on the other side of the drum surface at the means arranged to support and carry the drum surface, and that, seen from the end of the drum, the only point where the rope is unwound from the drum is located within the bearing area.
