Abstract
A suspension device for a heavy body, such as a rotating hopper for a shaft furnace, is presented. The suspension device has an annular running surface, a number (n) of rollers greater than three, and an elastically compressible component to permit elastic deformations sufficient substantially to correct an unequal distribution of weight of the heavy body over the rollers resulting from slight defects in the coplanarity of the rollers.
Claims23
A suspension device for a heavy body rotating about a substantially vertical axis of rotation, including:
- a running strip attached to said body, said running strip having an annular running surface therein;
- at least n rollers positioned to engage and press against said running surface to support said body, wherein n is an integer greater than 3;
- compressible elastic means between and connecting said running strip and said body to enable elastic deformation of said running surface about the points of contact between said rollers and said running surface;
- said compressible elastic means being effective to permit elastic deformations sufficient to establish weight bearing contact between said n rollers and said running surface;
- and
- said compressible elastic means being effective to permit elastic deformations sufficient substantially to correct an unequal distribution of the weight of said body over said rollers resulting from slight defects in the coplanarity of said n rollers.
A suspension device for a heavy body rotating about a substantially vertical axis of rotation, including:
- support means for supporting said body;
- a running strip, said running strip having an annular running surface thereon;
- at least n rollers positioned to engage and press against said running surface to support said body, wherein n is an integer greater than 3;
- compressible elastic means between and connecting said running strip and said body to enable elastic deformation of said running surface about the points of contact between said rollers and said running surface;
- said compressible elastic means being effective to permit elastic deformations sufficient to establish weight bearing contact between said n rollers and said running surface;
- said n rollers being mounted on one of said support means and said body, and said compressible elastic means and said running strip being attached to the other of said support means and said body;
- said compressible elastic means being effective to permit elastic deformations sufficient substantially to correct an unequal distribution of the weight of said body over said rollers resulting from slight defects in the coplanarity of said n rollers.
