Abstract
The present invention relates to Flexing-Disk Couplings that permit moderate angular and axial displacements between two rotating parts connected thereby. They contain a plurality of adjacent disks operating in parallel. Each disk transmits only a portion of the total torque. To keep the several disks acting in a similar manner, their outer ends at least are connected with one of said parts through yielding rubber-like layers, permitting said disks to slightly move out or in relatively to each other. This avoids high stresses when said parts tilt with respect to each other. The use of several disks in parallel permits to increase the load capacity or reduce the coupling diameter and weight.
Claims5
A flexing-disk coupling for connecting two rotating parts, comprising a plurality of generally circular disks secured to one of said parts at their inner portion,
- said disks extending along parallel planes in proximity of each other when the axes of said parts coincide,
- the outer ends of said disks being connected to the other of said parts through radially yielding rubber-like layers, to permit said outer ends to relatively expand and contract radially in tilting, whereby each disk transmits only a nearly equal fraction of the total torque transmitted by the coupling,
- said disks being of metal to keep them torsionally stiff, whereby to minimize relative angular deflection about the coupling axis,
- said layers being confined to the outer end portions of said disks and having a thickness smaller than the average thickness of the working portion of said disks.
