Polyurethane plum-shaped elastomer

　　Characteristics of polyurethane plum-shaped elastomer:
　　1. The pin of the elastic sleeve pin coupling is covered with a rubber ring, which has elasticity and the ability to compensate the axis displacement, but when the relative angular displacement is large, it is easy to wear;
　　2. Simple structure, convenient installation, easy replacement, small size, light weight, large transmission torque, widely used in various rotary pumps;
　　3、许用相对径向位移0.14-0.2mm；许用相对角位移0度40分；
　　4. The additional radial load caused by the relative displacement of the two shaft axes is (0.1-0.3)P;
　　5. The standard of the water pump industry is Bll01, its maximum allowable torque is 8316N•m, and the large shaft diameter is 200mm.
