<p>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.</p> |
