本文较系统地对芯型弹性联轴器进行了试验研究:对联轴器中的弹性件进行了运动分析、受力分析:通过台架试验得出了不同偏移对联轴器寿命的不同影响;提出了橡胶弹性件的失效形式及其转化以及判废的标准:并提出以失效形式转化时偏移量的临界值作为确定联轴器许用偏移量(静态)依据的观点。所得结论对以橡胶为弹性件的联轴器有共性意义。
In this paper, a systematic study on the core-type elastic coupling was carried out. The elastic analysis of the elastic coupling in the coupling was carried out, and the force analysis was carried out. The different influences of different displacements on the life of the coupling were obtained through the bench test. The failure modes of rubber elastic parts and the standards of their conversion and rejection are put forward. The critical value of offset in the conversion of failure form is proposed as the basis for determining the allowable displacement (static) of the coupling. The conclusion obtained has the same meaning to the coupling made of rubber.
