Flexible diaphragm shaft coupling assembly

摘要

A flexible coupling between drive and driven shaft members includes a diaphragm member having an offset base and outer periphery that is relatively more flexible than the radially inner base which is formed integrally with one of the shaft members or at least an intermediate coupling sleeve. A transition zone of the diaphragm extends through an arcuate curve to facilitate attachment between the shafts and one that will allow flexing of the diaphragm to accommodate dimensional changes in the shaft members as a result of cooling after assembly of the coupling.
