Reciprocating-piston IC engine with torsional vibration balancing

摘要

The engine (1) has for the purpose of torsional vibration balancing, a balancer shaft (6) which is driven by the crankshaft (2) via at least one gear stage. The balancer shaft is split into two parts. An input part (5) is connected by a universal joint (7) bent through a bend angle (a) to an output part (9) which carries a balance weight (8). The non-uniform rotational excitation by the engine is transformed into a uniform rotation at the output part as a function of the bend angle.
