Universal joints with needle bearing, Type EW
The table shows the transferable output N and/or torques M of universal joints 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 formular:
Torque M [Nm] = 9550 N[kW]/n [min-1]
Output N [kW] = M [Nm] x n [min-1]
1 kW = 1.36 PS / 1 PS = 0.736 kW
Torque to be transferred N = 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 = 1.43 x 23 Nm = 33 Nm
Intersection point P1 is arrived at from 33 Nm and 2300 min-1 (which is equivalent to an indicative output N = 7.9 kW).
The next size up universal joint corresponding to P1 is the model with a diameter d1 = 32.
