The values are applicable to a steady RPM, a stea- dy load and an inclination angle of max. 10°. 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 Needle Bearing, Type EW Determining the Size Example 1 Performance N to be transferred = 5.5 kW RPM n = 2300 min -1 Inclination angle ß = 10° Correction coefficient k = 1 Indicative performance N = Nominal performance N Intersection point P results from 5.5 kW and 2300 min- 1 (which corresponds to a torque of 23 Nm). The next larger universal joint corresponding to point P is the model with a diameter d 1 = 28 mm. Example 2 Torque M to be transferred = 23 Nm RPM n = 2300 min -1 Inclination angle ß = 18° Correction coefficient k = 1.43 Indicative torque M = 1.43 x 23 Nm= 33 Nm Intersection point P 1 results from 33 Nm and 2300 min- 1 (which corresponds to an indicative performance N = 7.9 kW). The next larger universal joint corresponding to point P 1 is the model with a diameter d 1 = 32 mm. N [kW] n [min -1 ] M [Nm] x n [min -1 ] 9550
