The reasonable disposition of the crankshaftcounterweight can minimize the maximum load on the main bearing, it is another problem of the design of the counterweight.
合理地布置平衡重的位置以使主轴承载荷的最大值达到最小，这是平衡重设计的又一问题。

The counterweight is installed on the crankshaft for reducing the bending moment on it, but it will influence the magnitude and distribution of the main bearing load.
