PTO transmission
In full compliance of the Manufacturer's transmission specifications, the kinematic forces from the power take-off to the relevant
apparatus should be carefully considered (angles, rpm, moment) during the design phase as well as the dynamic behaviour in the
installation phase.
This means that:
● the dimensions should take into consideration the forces which might occur under maximum power and torque conditions;
● to ensure effective kinetic forces, the shaft ends must be at the same angle (see Figure 1), and this angle must not exceed 7°;
● solution Z is preferred to solution W due to the lower loads on the bearings of the power take-off and the equipment being
driven. When it is necessary to obtain a different transmission line with spatial inclinations according to angle φ (as shown in
Figure 2), it is important to remember that the kinetic forces of the assembly can only be ensured if the intermediate section
has forks offset by the same angle φ and if equal conditions are respected between the angles at the extremities Χ
1
and Χ
2
.
For transmissions employing multiple sections, please refer to the indications provided in Chapter 2.8 ( ➠ Page 17).
