Elastic sleeve pin coupling for pump

泵用弹性套柱销联轴器目的是传递功率，补偿泵轴与电机轴的相对位移，降低对联轴器安装的   对中要求，缓和冲击，改变轴系的自振频率和避免发生危害性振动，比如Plum coupling，星形联轴器，弹性柱销套联轴器等。

泵用弹性套柱销联轴器的简单介绍：

①泵用弹性套柱销联轴器的柱销上套有橡胶圈，具有弹性和补偿轴线位移的能力，但相对角位移较大时，易磨损；

②泵用弹性套柱销联轴器结构简单，安装方便，   换容易，尺寸小，质量轻，传动转矩大，广泛应用于各种旋转泵中；

③The allowable relative radial displacement is 0.14-0.2mm; the allowable relative angular displacement is 0 degrees 40 minutes;

④ The additional radial load caused by the relative displacement of the two shaft axes is (0.1-0.3)P;

⑤The standard of the water pump industry is Bll01, its allowable torque is 8316N·m, and the shaft diameter is 200mm.
