<p>Conveyor roller which is capable of revolving in many directions. As one of its embodiments, the roller may also be used as a wheel revolving in many directions. The roller consists of a unilaterally triangular frame (3) in whose middle a bearing (1) is fitted for the main shaft of the roller. The shaft (4) of rotation of a roller disc (5) shaped as a segment of a sphere is placed as projecting perpendicularly from the middle of each side of the triangular frame. The sphere-segment disc has a corresponding, inwardly directed shaft bushing (6). The disc shaft and the shaft bushing in the disc are arranged so that they are locked together by means of a reversible deformation of the material of the bushing and/or of the shaft when the discs are pressed onto their shafts. In view of obtaining additional support for the discs, their peripheral areas may also be journalled (8, 9) against the side (3) of the triangular support. In the summit of the sphere segment (5), there may be an additional bearing (10).</p> |
