And the different torsional stiffness and damping factors available provided the possibility to satisfactorily tune the torsional vibration behaviour of the drive sys

3、tem.LS型高弹性联轴器主要由扭转弹 性部件、膜片部件、联接件及扭转限位 装置组成。扭转弹性部件由多个元件组 合而成，它根据结构尺寸和刚度级别的 要求布置成单排和多排型。每排弹性元 件又由多个扇形块组成。膜片部件是由 多个呈正切方向布置的挠性杆组成。它 们都是布置在弹性部件的后端，并允许 承受轴向位移。扭转限位装置是当弹性 部件破坏的瞬间，防止联接机器的断开, 这时就变成扭转刚度联接。The main parts of the LS coupling are: the torsionally flexible part, the membrane part the connecting pa

The torsionally flexible part consists of elements, which can be arranged in one row or more rows respectively, dependent on the coupling size and the stiffness level. The flexible elements are divided into several segments. The membrane part consists of a number o

If cracks or other failures about the flexible elelments are found while checking, they should be dismantled and changed immediately.弹性联轴器贮存Stock of LS Coupling暂不装机使用的弹性联轴器应保存在通风良好的仓库中，并要求避免太阳光直接照射，离发光源一米外，避免油类及碱性物的粘染，并处于自然状态。在正确保管条件下，库存期为 2 年

14、。The LS coupling,which is not used for the time being, should be kept in storehouse with good ventilation condition. And it should be prevented from being irradiated with sunlight directly and away from light source 1 meter. Also, it should avoid being inflected with oil and alkealine materials,and be in nature state.The stock period is 2 years with the normal store condition.
