    摘要：在采用平衡轴系统的活塞式引擎中,由于曲轴系统振荡而产生的二阶往复惯性力可以由带有平衡重的平衡轴来抵消,因此在对平衡重进行优化设计以及对轴颈重新设计后,平衡轴的重量可以得到很大的降低,这对于相似类型的平衡轴优化设计具有参考意义。

    Abstract: The oscillating movement of crank mechanism in piston engines produces free massive forces that are compensated by means of balancer shafts with specific unbalance.Based on an expedient arrangement of unbalanced masses and a new design of the bearing points,a partial bearing principle has been developed,which provides considerable weight reduction as compared to the conventional balancer shaft geometry.
