Technical Points for Cone Clamping Elements Tightening torque The tightening torque M S listed in the tables must be achieved during assembly and must not be exceeded by more than 10%. If the indicated tightening torque M S is not achieved, the transmissible torque or axial force, as well as the contact pressures at the shaft and at the hub will be proportionally reduced compared to the values listed in the tables for M or F as well as for P W and P N. When the indicated tightening torque M S is undercut by more than 30%, please contact us. Simultaneous transmission of torque and axial force The transmissible torques M which are shown in the tables apply for axial forces F = 0 kn and con versely, the indicated axial forces F apply to torques M = 0 Nm. If torque and axial force are to be transmitted simultaneously, the transmissible torque and the transmissible axial force are reduced compared to the values listed in the tables for M and F. For a given axial force F A, the reduced torque M red is calculated as: ßßßßßß M red =! M - (F A d ) For a given torque M A, the reduced axial force F red is calculated as: F red = d! ßßßß M - M A Bending moments Where there are bending moments in addition to the torque M A or the axial force F A, the transmissible torque or transmissible axial force is reduced compared to the values for M or F as listed in the tables. Please contact us. Hollow shafts When clamping hubs on hollow shafts with Cone Clamping Elements, the tangential stress s twi must not exceed the yield strength R e of the hollow shaft material. s twi = 1,7 P W C W = d Wi d 1 - C W with 6
Hub Design For the different Cone Clamping Element series, the tables list the required hub width N min and the required hub outer diameter K min for three exemplary yield strengths R e of the hub. Thereby, the hub is to be arranged as seen in figure 7-1 for Cone Clamping Elements with a fixed backstop point. For Cone Clamping Elements without a fixed backstop point, the hub is to be arranged according to figure 7-. For this, we practically assume that the clamping nuts of the Cone Clamping Element are flush with the hub on one side. When the actual load-bearing hub width N A is smaller than the required hub width N min and the yield strengths R e of the hub material is known, the required hub outer diameter K min can be calculated approximately as follows: K min = 1, D R H = ( ) e with When the hub width N A is known and the hub outer diameter K A is known, the hub material yield strength R e must be higher than the equivalent stress s v in the hub. 4 L s v = 1,7 P N 1!ßßßß 3 + C N with 1 - C N C N = H - 1,5 H - 3 1,7 P N N A D K A N A L 1 The load-bearing hub width N A in the application must not be smaller than the loadbearing width L 1.
