【摘要】 分析了扇形和偏心圆两种平衡轴设计的要求以及平衡重低质量的设计原则。扇形平衡重半径及宽度应尽量大、夹角应尽量小。偏心圆平衡重的偏心圆半径应尽可能大 ,轴承半径应尽可能小。同样质量的扇形平衡重产生的平衡力比偏心圆平衡重要大。更多还原

【Abstract】 In this paper the demands,the lowest mass design principle of balancer shaft of fan type and eccentric circle type balancer mass are analyzed.The radius and width of balancer mass should be larger,the included angle should be smaller for the fan type balancer mass.The radius of balancer mass should be larger,the radius of bearing should be smaller for the eccentric type balancer mass .The balance force of fan type balancer mass is larger than that of eccentric circle type balancer mass when the two types of balancer mass are the same.更多还原
