在工程机械制造中,对一些高速回转的零部件,必须进行静平衡试验。在平衡这类零件时,一般都是根据静力矩方程式G_1r_1-G_2r_2=0 (1)式中G_1——不平衡重量G_2——平衡重量r_1——不平衡重量的作用半径r_2——平衡重量的作用半径因为这种平衡方法是要满足等式(1);所以往往需做很多次试验才能达到平衡,做起 In the construction machinery manufacturing, for some high-speed rotating parts, static balance test. In the balance of such parts, are generally based on the static moment equation G_1r_1-G_2r_2 = 0 (1) where G_1 - unbalanced weight G_2 - the balance of weight r_1 - unbalanced weight of the role of the radius r_2 - balance of weight The radius of action because this method of equilibrium is to satisfy equation (1); therefore, it is often necessary to do many tests in order to achieve equilibrium
