MB Diaphragm coupling

Series MB coupling is an elastic multi-layer sheet coupling produced by our factory through digesting Danish Smith Company’s technique. In addition to the advantages of other metallic flexible couplings, it has below outstanding advantages: mounting is simple and convenient, needing no reaming hole bolts, it can better absorb the displacement generated by the double helical tooth shaft, it does not generate inertia “back gap” impact, it has no reciprocating swing impact. For the drive machine adopting double transmission, it can equalize the torque of these two transmission shafts and harmonize the synchronous running of the two slip frequencies, which are divided into MBH medium and high-speed series and MBL low speed heavy load series. The product is suitable for equipments like cement machinery, mine machinery, smelting, heavy-duty machinery, etc.

The longer shaft shall suitably use Type B (the weight is lightened by 50%~60%). If the shaft disc is connected at the speed reducer side, it shall be matched according to the shaft extension. (When L3 ≤320 mm, L4 will be matched according to the shaft extension.) (2) After Lc is determined, computed weight Wetc+LcWet (s)+connected shaft disc weight. (3) X is total number of the boltholes on one end flange (the both ends are the same), in which there are two locating match-reaming holes (intermediate d+2), and all bolts will be supplies with the coupling. (4) The total thickness of the adjustment ring spacer (three equal spacing along circumference) Smax=6×2 mm, in which 3×2 is the set adjustment amount. (5) Allowable speed Ncmax=120r/min, it is mainly used for the ball mill with speed≤25r/min.
