Patent ID: 10180177

Abstract:
The centrifugal mass arrangement for the balancing of rotational accelerations of an engine housing of a reciprocating-piston engine, such as an internal combustion engine, is equipped with a hollow cylindrical housing provided for fastening to the engine housing and has a circumferential wall with an inner side, and with a centrifugal mass carrier arranged rotatably in the housing and coupled to the drive shaft for co-rotation therewith. The centrifugal mass carrier has at least two diametrically oppositely situated ends. A roller disk with a circumferential surface is arranged on each end of the centrifugal mass carrier. Each roller disk is mounted rotatably on the respective end of the centrifugal mass carrier and is supported by the circumferential surface against the inner side of the circumferential wall of the housing and, during rotation of the centrifugal mass carrier, rolls on the inner side of the circumferential wall of the housing.
