关于联轴器的选择问题

联轴器的选择主要考虑所需传递轴转速的高低、载荷的大小、被联接两部件的安装精度等、回转的平稳性、价格等，参考各类联轴器的特性，选择一种合用的联轴器类型。具体选择时可考虑以下几点：

1．2联轴器的工作转速高低和引起的离心力大小。对于高速传动轴，应选用平衡精度高的联轴器，例如膜片联轴器等，而不宜选用存在偏心的滑块联轴器等。

1 . 3所需传递的转矩大小和性质以及对缓冲振动功能的要求。例如，对大功率的重载传动，可选用齿式联轴器。对严重冲击载荷或要求消除轴系扭转振动的传动，可选用轮胎式联轴器等。

绝大多数联轴器均已标准化或规格化(见有关手册)。设计者的任务是选用，而不是设计。选用联轴器的基本步骤如下：

5）联轴器的制造、安装、维护和成本。在满足便用性能的前提下，应选用装拆方便、维护简单、成本低的联轴器。例如刚性联轴器不但结构简单，而且装拆方便，可用于低速、刚性大的传动轴。一般的非金属弹性元件联轴器(例如弹性套柱销联轴器、弹性柱销联轴器、梅花形弹性联轴器等)，由于具有良好的综合能力，广泛适用于一般的中、小功率传动。
