Balancer shaft gear for reciprocating piston internal combustion engine, has two balancing weights that are mateable at two balancer shafts such that masses of balancing weights are arrangeable diametrically together at balancer shafts

摘要

The gear has two balancing weights that are mateable at two balancer shafts (1, 2) in such a manner that the masses of the balancing weights are arrangeable diametrically together at the balancer shafts so that the centrifugal force effect of the two balancing weights works against the maximum concentricity errors of two gear wheels (7, 8). The concentricity errors are measurable by an axis-center distance measurement with a master gear wheel.
