Selection of size of Universal joints with friction bearing DIN 808, Type EG

The table shows the transferable output N and/or torques M of universal joints DIN 808, Type EG(single friction 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°. They are not applicable to universal joints in St. Steel. 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 Output to be transferred N = 0,65 kW R.p.m. n = 230 min-1 Angle of inclination ß = 10° Correction coefficient k = 1 Indicative output N' = Nennleistung N Schnittpunkt P ergibt sich aus 0,65 kW und 230 min-1 (was einem Drehmoment von 27 Nm entspricht). Das Punkt P entsprechende nächstgrößere Gelenk ist d1 = 25. Example 2 Torque to be transferred M= 27 Nm R.p.m. n = 230 min-1 Angle of inclination ß = 30° Correction coefficient k = 2,25 Indicative output M' = 2,25 x 27 Nm = 61 Nm Intersection point P1 is arrived at from 61 Nm and 230 rpm-1 (which is equivalent to an indicative output N' = 1,44 kW). The next size up universal joint corresponding to P1 is the model with a diameter d1 = 36.
