Locking device coupling RfN 7012

The bending moment acting on the hub/shaft connection is the main load to evaluate in a belt drum or similar application. Excessive bending moments can cause overstress in the webs between the screw holes in the locking assembly. In the case of additional loads (bending moments/ radial loads) screw tightening torques may have to be reduced. To limit the influence of the bending load on the locking assembly connection we use the following criteria during the belt drum design process: - Shaft deflection from the bending moments can only have a maximum deflection fm < 1/2000 * L (bearing centre distance). - For the permissible bending load values please refer to our tables. Product Characteristics One of the most demanding challenges of our promise of performance is the conveyor pulley application field. The extreme loads which such components are subject to, especially the high bending moment, coupled with the simultaneous indispensable reliability and longest possible service life, require the highest of engineering know-how. Our international development team, which has already set benchmarks in quality Locking Assemblies for the RfN 7012, RfN 7012.2, RfN 7015.0 and RfN 7015.1 products, is here setting a further milestone. Quality means: high-quality materials and material services, and the most precise workmanship, guarantee sustainable product usage. Performance means: reliability, and long service life means: minimization of machine downtime and maximization of service life. Price means: not just the newest, but also the most economical RINGFEDER® Locking Assemblies product at the high level of performance you are used to.
