The invention relates to a supporting roller set for tiltable, axially movable and rotatable support for a rotary drum which can be driven in rotation. It comprises two supporting rollers which lie symmetrically on both sides of a vertical longitudinal central plane of the rotary drum and are each mounted in two rotary bearings which are fixed on bedplate which is tiltably supported on a static foundation. In order to be able to achieve an optimal self-adjustment with easy action of each supporting roller, each bedplate is supported by way of two articulated bearings disposed at a transverse spacing from one another on the foundation, of which the inner articulated bearing is constructed in the form of a ball-and-socket bearing, whilst the outer articulated bearing forms a movable bearing and is supported on the foundation so as to be slidably movable about the central point of the ball of the inner articulated bearing.
Supporting roller set for tiltable, axially movable and rotatable support for a rotary drum (1) which can be driven in rotation, which contains two supporting rollers (3) which lie symmetrically on both sides of a vertical longitudinal central plane (1b) of the rotary drum (1), a running surface (4) of the rotary drum (1) being rotatably supported and on the outer circumferential surfaces (3a) of the said supporting rollers, wherein each of these supporting rollers is freely rotatably mounted by way of its supporting roller axle (3b) in two rotary bearings (5) which are fixed bedplate (6) tiltably supported on a static foundation (7, 8), characterised in that each bedplate (6) bearing a supporting roller (3)—when viewed transversely with respect to the rotary drum (1) and to the supporting rollers (3)—is supported on the foundation (7, 8) by way of two articulated bearings (9, 10) which are transversely spaced (QA) from one another, of which the inner articulated bearing (9) which lies nearer to the vertical longitudinal central axis (1b) of the rotary drum (1) is constructed in the form of a ball-and-socket bearing and as a fixed bearing is supported statically on the foundation (7, 8), whilst the outer articulated bearing (10) which lies further away from this vertical longitudinal central plane (1b) forms a movable bearing and is supported so as to be slidably movable on the foundation (7, 8) approximately in the shape of an arc of a circle about the central point (9) of the ball of the inner ball-and-socket bearing (9).
