INTRODUCTION PRELIMINAR STUDIES AND CONSIDERATIONS
MOUNTING AND CONSTRUCTION
Remark on types of angular movements on propeller shafts:
The use of only one Cardan Joint (or universal joint) is not permitted, since with this
configuration the output shaft or secondary is not moving at constant angular speed
when an angle (φ) exsits with respect to the input shaft or primary. This defect is
called Cardan Error and produces alternate advances and a delays in the rotational
speed of the output shaft.

To avoid this problem, two universal joints are placed in tandem with an intermediate
shaft, according to different configurations:
W-configuration and Z-configuration:
In these cases the two inner yokes of the joint must be in the same plane, and the
input and output shafts must also be contained in a common deflection plane and
both joints must have the same working angle (β1 = β2).
