Title: Improvements relating to highly resilient shaft coupling devices
IPC: F16D3/50
Filed: 1981-06-24
Abstract: A first coupling (3) has a linear characteristic and its resilient transmission elements (9) are preferably elastomers, a second coupling (4) has a progressive characteristic and its resilient transmission elements (19) are preferably elastomers having extra- strength reinforcing inserts. The linear coupling (3) extends co-axially around the progressive coupling (4) and the inner coupling and outer coupling (4,3) each have one flange (2, 1) at opposite axial ends for connection to the shafts to be interconnected. The two individual couplings are resiliently movable relative to one another axially, radially and in rotation. This produces a characteristic which is basically progressive but whose progressiveness is less than that of a conventional progressive characteristic, so that the coupling device has increased torsional resilience in the full-load range. <IMAGE>
