Selection of size of Universal joints with needle bearing DIN 808, Type EW

The table shows the transferable output N and/or torques M of universal joints Kreuzgelenken DIN 808, Type EW(single needle bearing) in relation to the r.p.m. n. The values are only applicable to a constant speed of rotation, constant load and an operating inclination angle of max. 10°. For larger inclination angles ß a nominal output N' increased by the correction coefficient k and/or a nominal torque M' has to be selected (see example below). Conversion formulae:   N [kW]  Torque M [Nm]= 9550 n [min-1] Output N [kW] = M [Nm] x n [min-1] 1 kW = 1,36 PS 1 PS = 0,736 kW Example 1 Torque to be transferredN = 5,5 kW R.p.m. n = 2300 min-1 Angle of inclination ß = 10° Correction coefficient k= 1 Indicative output N' = Nominal output N Intersection point P is arrived at from 5,5 kW and 2300 min-1 (which corresponds to a torque of 23 Nm). The next size up universal joint corresponding to point P is the model with a diameter d1 = 28. Example 2 Torque to be transferred M= 23 Nm R.p.m. n = 2300 min-1 Angle of inclination ß = 18° Correction coefficient k = 1,43 Indicative torque M'   = 1,43 x 23 Nm = 33 Nm Intersection point P1 is arrived at from 33 Nm and 2300 rpm-1 (which is equivalent to an indicative output N' = 8,3 kW). The next size up universal joint corresponding to P1 is the model with a diameter d1 = 32.
