摘　　要：恰当的周向刚度是膜片联轴器实现挠性传动的重要因素。论文首先根据现场所见的膜片组受压张口,指出张口对膜片联轴器周向刚度的可能影响。然后对张口前后的受压段膜片分别进行理论分析,指出拉压段膜片的周向扭转刚度变化。两相比较,验证了笔者的猜想。Proper torsional rigidity is an important factor for diaphragm couplings to achieve flexible transmission. Firstly,according to the dehiscence of diaphragms under pressure observed in the field test,this paper points out the possible influence of the diaphragms＇ slit on its torsional rigidity. Then this paper theoretically analyzes the compressed section of diaphragms respectively before and after the dehiscence occurs,points out the changes of the torsional rigidity of tensile and compressive sections of the diaphragms. Comparing the two,the author verifies the conjecture.
