Abstract: In recent years smart materials of magneto-rheological fluid are widely used in various fields.However,few studies focus on the metallurgical equipment driving parts.For a rolling mill roller driving system,the limit torque cylindrical magneticfluid coupling was designed and analyzed in this paper using the permanent magnets as the magnetic source.Based on the principle of permanent magnetic fluid coupling,structural design and method of the optimizing structure parameters were discussed;according to the Bingham model,the momentum equation and torque calculation formula of permanent magnetic fluid coupling were derived for further design of the coupling.
