RINGFEDER® Locking Elements Introduction For over 90 years, our product offering of RINGFEDER® Locking Elements has been unparalleled in the industry. Products that offer you the highest level of quality and precision. RINGFEDER® Locking Elements are wear- and maintenance-free. High fatigue strength under alternating torsional stresses – as neither the shaft nor the hub have grooves the notch effect is minimized and a higher polar section modulus is given, enabling the use of smaller diameters. Simple installation – in comparison to cross-press fits temperature treatments and fitting are eliminated....

Locking screw calculation & Locking screw table The torque transmission capacity of a RINGFEDER® Locking Element connection is directly proportional to the effective clamping force FA. As clamping elements normally locking srews are used which act on the Locking Elements via a thrust flange. According to the required tension force, the selection according to screw quality, size and quantity can be done according to the chart below. Required screw tension force for Locking Elements solid: FA = FA´ + F0 for Locking Elements slit: Regular thread 1), metric 8.8 dG M4 Where n-Locking Elements are...

Tech Paper Locking Elements RINGFEDER® RfN 8006 Explanation d Fax100 = Transmissible axial force based on p =100 N/mm2 = Clamping force for gap filling when manufacturing tolerances are exploited. Not applicable for slit versions. = Needed clamping force to get a shaft pressure of 100 N/mm2 = Diameter spacer sleeve inside = Transmissible torque based on p =100 N/mm2 = Diameter spacer sleeve outside Tmax = Max. transmissible torque X (n) = Min. distance to thrust flange for n Locking Elements. Any reduction of this values could cause that the required transmission value is not achieved. * Generally...
