Locking Assemblies for Bending Loads | RINGFEDER®

Uncompromising performance under extreme loads with specially developed RINGFEDER® Locking Assemblies for Bending Loads: One of the most challenging applications for our locking devices are belt drums which are used, e.g., in mostly large-scale conveyor systems for iron or copper ore, coal and other mineral resources. The shaft-hub connections used between the drum shaft and the drum base are subject to enormous additional stresses by axial and transverse forces and especially by bending loads which – in addition to the required torque – must be transmitted constantly and reliably. Therefore, RINGFEDER® Locking Assemblies for Bending Loads have been optimized in regard to material strength, surface quality and internal tension in order to effectively prevent e.g. shaft breakage, axial migration or plastic deformation of the drum base and thus cost-intensive repairs and production downtimes. The backlash-free, friction-fit locking devices ensure highest possible operational dependability in belt drum applications and are also convincing due to their easy handling as well as complete freedom from wear and maintenance.
