Balancer for 90 degrees V-6 engines and the like.

摘要

An even-firing 90 DEG V-6 four-stroke cycle engine is provided with a single-line balancer (57) having a combination of primary balance weights (85 to 88) and secondary Oldham coupling balancers (80) rotating in a direction opposite to the direction of rotation of the crankshaft (16) which, combined with crankshaft counterweights (52 to 55), provide complete offsetting of the primary rotating unbalance couple of the engine together with offsetting of a large portion of the secondary rotating unbalance couple of the engine, leaving a small residual secondary unbalance couple for absorption by the engine mounting system.
