Joint disc structure for connecting the driving and driven shaft ends, has elastomeric stock material layer that is arranged between adjacent end surfaces of loop package assemblies of coupling unit

摘要

The joint disc structure (10) has a coupling unit that is provided with loop package assemblies (30,32a,32b). The coupling unit and the loop package assemblies are embedded in an elastomeric coupling mass portion (16). An elastomeric stock material layer (34) is arranged between the adjacent end surfaces of the loop package assemblies. The stock material layer and a spacer later are made of vulcanized natural or synthetic rubber, thermoplastic elastomer, flexible plastic or unvulcanized natural or synthetic rubber.
