HEAVY CASING SUSPENDING APPARATUS Russian patent published in 1999 - IPC

FIELD: metallurgy, in particular, shaft furnace charging equipment. SUBSTANCE: apparatus for suspending rotating casing such as rotating hoppers has metal supporting strip defining annular roller surface and positioned at its one side, and at least n metal rollers positioned at its other side, with n being whole number greater than 3. Rollers abut against roller surface. Flexible compressible member positioned under metal supporting strip is manufactured from metal and provided with elongated openings extending in parallel with roller surface, which is elastically deformed relative to points of contact with rollers. Sizes of flexible compressible members are selected such that elastic deformation of roller surface is sufficient for providing uniform distribution of load from weight of rotating hopper on n rollers, with slight nonplanarity in arrangement of n rollers being compensated. EFFECT: simplified construction, increased efficiency by reliable uniform distribution of load on rollers. 13 cl, 9 dwg
