Abstract
A belt and roller system comprising a roller having a permanent magnet sandwiched in between a pair of temporarily magnetic disks with the magnetism of the disks induced by the permanent magnet. Each temporarily magnetic disk may be steel. Each pole of the permanent magnet is disposed adjacent to a pole of one of the temporarily magnetic disks resulting in a magnetic attraction to a disk at each pole of the permanent magnet. The opposing magnetic poles of the disks form a magnetic flux circuit by which a temporarily magnetic belt, such as a steel belt is guidable to prevent or reduce deviation which it may have from its roller path. Additional permanent magnetic rollers or other rollers known in the art may be combined with the magnetic roller of the present invention to form a gear train about which the belt rotates.
Claims13
A belt and roller system comprising:
- a temporarily magnetic belt;
- and
- a first roller comprising a permanent magnet having magnetic poles and being disposed between two temporarily magnetic disks having induced magnetic poles, a first permanent magnetic pole magnetically attracted to a pole of one of the disks and a second permanent magnetic pole magnetically attracted to the pole of the other of the disks, wherein the belt is in drive relation to the roller.
A belt and roller system comprising:
- a steel magnetic belt;
- and
- a first roller comprising a permanent magnet having magnetic poles and being disposed between two steel disks having induced magnetic poles, a first permanent magnetic pole magnetically attracted to an adjacent pole of one of the steel disks and a second permanent magnetic pole magnetically attracted to an adjacent pole of the other of the steel disks, the steel belt in drive relation to the roller.
A drive mechanism comprising:
- a rotating input shaft driving a plurality of axles of a plurality of rotatable input magnetic rollers surrounding an output magnetic roller arranged to rotate inwardly of the input rollers and having a rotating output shaft;
- a fixed ring outwardly supporting the input magnetic rollers;
- and
- each magnetic roller having a pair of temporarily magnetic disks on opposed sides of a permanent magnet thereby having different magnetic polarities, the polarities of the input magnetic rollers all being the same and being magnetically coupled to the output magnetic roller thereby driving the rotating output shaft.
