在需要缓和冲击,降低动负荷或降低运动系统的自然频率时常采用弹性联轴器。现有弹性联轴器的结构种类虽不少,但能在大功率及转速不稳定的条件下,能满意运行的却不多。经常出现的问题是弹性元件寿命短,容易损坏。我们在仿制国外产品的基础上,自行设计了一种采用普通平皮带作为弹性元件的联轴器,经一年多的使用实践,获得了较好的效果。该联 Flexible couplings are often used when it is required to mitigate impact, reduce dynamic loading, or reduce the natural frequency of a moving system. Although there are many kinds of structures of the existing flexible couplings, they can operate satisfactorily under the conditions of high power and speed instability. Often the problem is that the elastic element has a short life and is easily damaged. Based on the imitation of foreign products, we designed a kind of coupling using ordinary flat belt as the elastic component. After more than one year of practice, we achieved good results. The couple
