Bestimmung der Größe von Kreuzgelenken mit Nadellager DIN 808, Form EW

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^-1Angle 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^-1Angle 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 2300rpm^-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.
