Three-dimensional deflection

sal-joints of the connecting shaft must be offset. This offset
angle is designated with µ (see Figure 5.27).
The following applies to determine the offset angle µ:

The offset angle µ can be determined with the horizontal and

A three-dimensional
deflection is an in-
tersection
of
centerlines of input
and output shaft with
spacious offset. A
common plane just
like with W or Z de-
flection does not ex-

pensate the speed

5.11.3 Forces in the drive shaft system
Forces are introduced as a result of the angle of deflection in
the drive shaft. Additional forces are created if the drive shaft
is laterally displaced under the concurrent effect of force and
torque. The type, magnitude and direction of the additional
forces are dependent on the relevant operating status and the
type of drive shaft arrangement.
Mechanical drive of implements
An infinite number of possible positions
may be created by the combination of the
vertical and horizontal angle of deflec-
tion. In order to better determine the off-
set angle, the pro shaft manufacturer
should be involved in an advisory capac-
ity.
