BALANCING APPARATUS FOR A VEHICLE ENGINE

摘要

A balancing apparatus for a vehicle engine has a housing assembly constructed an d arranged to be mounted to the vehicle engine. The housing has spaced apart endwa lls and two parallel extending support shafts connected to the endwalls. A first hollow shaf t is rotatably mounted concentrically about a first of the support shafts. A first gear is moun ted for rotation with the first hollow shaft. A first balance weight is mounted for rotation with the first hollow shaft and spaced from the first gear. A second hollow shaft is rotatably mounted concentrically about a second of the support shafts. A second gear is mounted for rotation with the second hollow shaft. The second gear is in driven engagement with the first gear for co unter rotation therewith. The first of the support shafts is positioned relative to the engine crankshaft for drivingly engaging the first gear with the crankshaft. A second balance weight i s mounted for rotation with the second hollow shaft and spaced from the second gear for rotati on in a plane common with the first balance weight. The second balance weight is positioned di ametrically opposite to the first balance weight for counter rotation therewith.
