1. The elastic pin coupling is a pin made of several non-metallic elastic materials, which is placed in the flange hole of the two halves of the coupling, and the two halves of the coupling are connected by the pin. The coupling has a simple structure , It is easy to manufacture, and it is convenient to assemble and disassemble the elastic element without moving the two halves of the coupling.The material of the elastic element (column pin) is generally selected from nylon, which has the ability to compensate the deviation of the two axes in a small amount. The elastic part is sheared when working, and the workability is poor. It is only suitable for the medium-speed transmission shaft system with very low requirements, not suitable for workability More demanding conditions.
2、轴孔型式有圆柱形(Y)、圆锥形(Z)和短圆柱形(J)。轴孔和键槽按标准GB3852-83《联轴器轴柱和键槽形式及尺寸》的规定加工。半联轴器采用铸造,铸铁HT20-40、铸钢ZG35Ⅱ,轴孔和键槽采用拉制成型,柱销采用MC尼龙b制成。
3、HL型-弹性柱销联轴器已列为标准GB5014-85,适用于各种机械联接两同轴线的传动轴,通常用于动频繁的高低速运动。工作温度为-20 ~+80℃;传递公称扭矩为40~20000N。m。
4. The elastic pin coupling has a relatively large structure, simple and reasonable, convenient maintenance, symmetrical and interchangeable on both sides, long life, allowing large axial movement, and has buffering, shock absorption, and other properties.
