ABSTRACT:
A reciprocating internal combustion engine which is enclosed by a sound-insulating sheath comprises a crankshaft. A coupling which insulates against structure-borne sound is provided for coupling the crankshaft to an auxiliary drive shaft for driving auxiliary devices disposed outside said sheath. Said coupling comprises a resilient ring and axially parallel connecting screws, which are peripherally spaced apart and are secured in alternation to the crankshaft and to the drive shaft and extend through tubular spacers mounted in the ring. The drive shaft is rotatably mounted in a mounting plate, which is fixed to a crossbeam. The internal combustion engine is supported on the crossbeam by an annular member which insulates against structure-borne sound. In order to reduce the radial excursions of the resilient ring to a permissible extent, the resilient ring is disposed between and radially restrained by two restrining plates, one of said restraining plates in non-rotatably connected to the crankshaft by those of the connecting screws which are secured to the crankshaft, the other of said plates is non-rotatably connected to the drive shaft by those of the connecting screws which are fixed to the auxiliary drive shaft, and at least one of said restraining plates is rigid with a cylinder, which coaxially extends into the resilient ring as a press fit.
