Description: |
| Abstract:
This invention refers to a method of taking up the end-pressure of rotating shafts with the view of diminishing the frictional resistance and of preventing the shaft or the pivot from running hot and welding fast. For this purpose the end of the shaft is made to abut against or stand upon either one disk movable around its center, which disk, during the rotation of the shaft by the friction between the surfaces touching each other, is caused to rotate, or upon two such disks placed beside each other, but independent of each other, which, during the rotation of the shaft, are caused to rotate in opposite directions. In order to make the frictional resistance as small as possible, the whole disk ought in the first case to be placed at the side of the center of the shaft, and in the latter case the center of the shaft should be situated between the disks. The center of the shaft may, however, be placed a little in upon the disk or upon one of the disks, and there will nevertheless be a guarantee for not getting fast, even though the frictional resistance then augment a little; but the center of the shaft should never stand quite upon or very near the midst of the disk.
Claim:
The combination, with a rotative shaft having an endwise weight or pressure, of one or more disks and a supporting-shaft for the same, the end of the rotative shaft resting against the edge of such disk or disks. |
