什么是弹性柱销齿式联轴器?怎样选择联轴器

2015-05-31 19:15:12 admin

　弹性柱销齿式联轴器具有一定补偿两轴相对偏移的性能，适用于中等和较大功率传动，不适用于对减振有一定要求和噪声需要严加控制的工作部位。弹性柱销齿式联轴器是利用若干非金属材料制成的柱销，置于两半联轴器与外环内表面之间的对合孔中，通过柱销传递转矩实现两半联轴器联接，该联轴器具有以下特点：

　　一、弹性柱销齿式联轴器传递转矩大，在相同转矩时回转直径大多数比齿式联轴器小，体积小，质量轻，可部分代替齿式联轴器，与齿式联轴器相比，结构简单，组成零件较少，制造较方便，不用齿轮加工机床。

　　二、弹性柱销齿式联轴器维修方便，寿命较长，拆下档板即可更换尼龙柱销，尼龙柱销为自润材料，不需润滑，不仅节省润滑油，而且净化工作环境。

　　三、弹性柱销齿式联轴器不足之处是减振动能差，噪声较大，但成本低，价格便宜，所以在输送机械、冶金机械应用很广泛。
