Description
[0024] Respectively schematically:
[0025] FIG. 1 shows a vertical cross-section of a bearing housing support according to the invention for the floating roller,
[0026] FIG. 2 shows a side view of a section of the floating roller side of a two-high roller press with the bearing housing support of the floating roller according to the invention,
[0027] FIG. 3 shows a side view of a section of the fixed roller side of a two-high roller press with the bearing housing support for the fixed roller according to the invention,
[0028] FIG. 1 schematically shows a vertical cross-section of an illustrative example of a bearing housing support 1 according to the invention for the floating roller in a two-high roller press, in which the axis of rotation of the floating roller is vertical to the plane of the drawing. The shaft of the floating roller is supported in cylindrical roller bearings with cylindrical roller elements (not shown). On bearing housing 2 of a cylindrical roller bearing rests a load distribution element 3, which exhibits two equivalent, prismatic elastic individual elements 31a, 31b, for example rubber elements, in which the elastic individual element 31a is arranged on the upper half of the bearing housing and the elastic individual element 31b is arranged on the lower half of the bearing housing. The individual elements 31a, 31b extend in the horizontal direction over the entire width of the bearing housing 2. In a vertical direction, the load distribution element 3 encloses somewhat with the upper and lower cover surface of the bearing housing 2. Between the individual elements 31a, 31b is located a recess 32 which, as with the load distribution element 3, is symmetrical in relation to the horizontal central plane of the bearing housing 2. On the surface 33a, 33b of an individual element 31a, 31b, opposite to the surface 34a, 34b resting on the bearing housing 2, precisely fitting metal stamps 4a, 4b are arranged as means of transferring pressure, in which the size of the contact surface of the metal stamps 4a, 4b corresponds to the individual elements 31a, 31b of the size of surface 33a, 33b. Each individual element 31a, 31b is enclosed by a closed edge. This is illustrated in the horizontal direction (vertical to the plane of the drawing) by raised supporting walls 21a, 21b welded onto the bearing housing (each individual element 31a, 31b is therefore guided into a horizontally-aligned groove) and in a vertical direction (parallel to the plane of the drawing) on both sides are supporting plates (not shown) fastened by force-fit to the bearing housing 2 and to the horizontal supporting walls 21a, 21b (not shown). Each individual element 31a, 31b is enclosed piston-like by the supporting walls 21a, 21b and the supporting plates (not shown). The supporting walls 21a, 21b and the supporting plates (not shown) extend over the relevant individual element 31a, 31b on the surface 33a, 33b, so that also the section of the stamp 4a, 4b facing towards the surface 33a, 33b is enclosed and supported by the edge of the individual element 31a, 31b. The stamps 4a, 4b are respectively connected via an articulated and sprung screw connection to spacers 5a, 5b. The spacers 5a, 5b are connected to a hydraulic cylinder 6 for the application of the pressing force.
[0029] FIG. 2 shows in sections a side view of the floating roller side of a two-high roller press with bearing housing support 1 according to the invention, as shown in FIG. 1. In this case, the axis of rotation of the roller (not shown) is vertical to the plane of the drawing. The bearing housing 2 exhibits a load distribution element 3 with two spatially-separated, elastic individual elements (concealed here), between which a recess 32 is located, that is symmetrical in relation to the horizontal central plane of the bearing housing 2 (indicated by the horizontal dotted line). The enclosed edge of the individual elements (concealed here) is formed in the horizontal direction by the supporting walls 21a, 21b (partially concealed) welded onto the bearing housing 2 and in the vertical direction by the supporting plates 22a, 22b connected by force-fit with the supporting walls. The enclosed edge therefore supports a section of the stamps 4a, 4b resting on the individual elements. The stamps 4a, 4b are connected by an articulated and sprung screw connection with spacers 5a, 5b, that is in turn connected to a hydraulic cylinder 6 for applying the pressing force. The hydraulic cylinder 6 is fastened to the vertical pillars 7 of the machine frame of the two-high roller press. The bearing housing support 1 according to the invention is of identical construction for the fixed bearing and floating bearing side of the floating roller.
[0030] FIG. 3 shows sections of a side view of the fixed roller side of a two-high roller press with a bearing housing support 1 according to the invention. As in FIG. 2, the axis of rotation of the roller (not shown) is vertical to the plane of the drawing. The bearing housing support 1 on the fixed bearing and floating bearing side of the fixed roller side is the same construction as the bearing housing support 1 on both bearing sides of the floating bearing, as shown in FIG. 1 and FIG. 2. In contrast to the floating bearing side, the spacers 5a, 5b on the fixed roller side are fastened directly to the vertical pillars 7 of the machine frame of the two-high roller press.
