Page 1644 | 3.6 Moving, Transferring, Connecting with Shafts and Joints The graph shows the transferable performance N and the torques M of universal joints DIN 808, type EG (single jointed, friction bearing) in relation to the RPM n. The values are applicable to a steady RPM, a steady load and an inclination angle of max. 10°. They are not applicable to stainless steel universal joints. For larger inclination angles ß, a nominal perfor- mance N increased by the correction coefficient k and/or a nominal torque M has to be selected (see example below). Conversion formulae: Torque M [Nm] = 9550 Performance N [kW] = 1 kW = 1.36 PS 1 PS = 0.736 kW Universal Joints with Friction Bearing, Type EG Determining the Size Example 1 Performance N to be transferred = 0.65 kW RPM n = 230 min -1 Inclination angle ß = 10° Correction coefficient k = 1 Indicative performance N = Nominal performance N Intersection point P results from 0.65 kW and 230 min- 1 (which corresponds to a torque of 27 Nm). The next larger universal joint corresponding to point P is the model with a diameter d 1 = 25 mm. Example 2 Torque M to be transferred = 27 Nm RPM n = 230 min -1 Inclination angle ß = 30° Correction coefficient k = 2.25 Indicative torque M = 2.25 x 27 Nm = 60 Nm Intersection point P 1 results from 61 Nm and 230 min -1 (which corresponds to an indicative performance N = 1.47 kW). The next larger universal joint corresponding to point P 1 is the model with a diameter d 1 = 36 mm. N [kW] n [min -1 ] M [Nm] x n [min -1 ] 9550
