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 support of a rotary drum

In this tiltable supporting roller bearing according to the invention for supporting a rotary drum there are provided a freely rotatably mounted supporting roller and an appertaining bearing structure which is tiltably supported with respect to a stationary foundation plate with the aid of easily shifted support bearings which are arranged inclined against one another in such a way that the point of rotation of the line of contact between the supporting roller and the riding ring of the rotary drum lies with the vertical central axis of the supporting roller. With a particularly simple and reliable design, this construction makes it possible to compensate for skewing of the rotary drum riding ring and at the same time markedly to reduce or largely avoid undesirable consequences of the axial forces resulting from longitudinal movements of the rotary drum.

Tiltable supporting roller bearing

The invention relates to a rotary drum with relatively large dimensions, the shell of which is supported by means of riding rings each on a pair of supporting rollers of a supporting roller stand. For this purpose the rotary drum shell merely bears two riding rings which are attached so as to be fixed against rotation and which are supported on two supporting roller stands of which at least one simultaneously forms the rotary drive arrangement for the rotary drum in the form of a friction drive. This produces a combination of features by means of which the mounting of the rotary drum is statically determinate and can be driven reliably in an extremely simple manner.
