Elastic sleeve column pin coupling for pumps

① The column pin of the elastic sleeve column pin coupling is fitted with a rubber ring, which has the ability to be elastic and compensate for axial displacement. However, when the relative angular displacement is large, it is prone to wear and tear;
② Simple structure, easy installation, easy replacement, small size, light weight, high transmission torque, widely used in various rotary pumps;
③ Allowable relative radial displacement of 0.14-0.2mm; Allowable relative angular displacement of 0 degrees and 40 minutes;
④ The additional radial load generated by the relative displacement of the two axis lines is (0.1-0.3) P;
⑤ The standard for the water pump industry is Bll01, with a maximum allowable torque of 8316N · m and a maximum shaft diameter of 200mm
