发明名称 MASS BALANCING DEVICE FOR A RECIPROCATING PISTON INTERNAL COMBUSTION ENGINE
摘要 The invention relates to a mass balancing device (1a, 1b) for a reciprocating piston internal combustion engine, comprising a first balancing shaft (2a, 2b) and a second balancing shaft (3a, 3b) disposed in the first balancing shaft coaxially thereto, the first balancing shaft (2a, 2b) comprising at least one bearing point (6a, 7a, 6b, 7b) for a first rolling bearing (16) and the second balancing shaft (3a, 3b) comprising at least one bearing point (8a, 9a, 8b, 9b) for a second rolling bearing (17), by means of which rolling bearings the balancing shafts are radially supported in the reciprocating piston internal combustion engine. At least one of the bearing locations shall be designed as a hollow cylinder having an outer shell surface serving as the bearing seat for the first rolling bearing and an inner shell surface serving as the bearing seat for the second rolling bearing, such that the first rolling bearing and the second rolling bearing overlap one another axially.
