膜盘联轴器力学性能研究与优化设计

Research oa Mechanical Behavior of the Diaphragm-Coupling and Optimal Design

<正> 膜盘联轴器是近几年发展起来的一种新型的联轴装置,它具有结构简单、无需润滑、运行平衡、振动小、噪音低、操作维护方便等许多优点,被广泛应用于石油化工、机电航空等部门.膜盘联轴器大多用来驱动高速、大功率的设备,膜盘联轴器的关键构件是两端的“膜盘”,它是一对变厚度的薄板,最薄处仅0.2～0.4mm,外缘是一个法兰盘。

The molded line of the diaphragm-coupling is a thin plate with varying thickness,and its service life depends on its thickness distribution.In this paper,an optimazation seheme is employed on the basis of finite element analysis on mechanical behavior according to the molded line under different Ioadings.The mechanical property of there optimally designed products reaches up to that of imported ones.
