Bestimmung der Größe von Kreuzgelenken mit Gleitlager DIN 808, Form EG

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^-1Angle 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^-1Angle 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 230rpm^-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.
