Abstract
The technological (geometrical) deviations determine in the intermediate couples of the cardan joint supplementary efforts due to restrained movement. The 4R spherical quadrilateral mechanism, where by R is notated the rotation kinematic pair, from which is obtained the cardan mechanism, is of third family, as consequence, multiple statically indeterminate and for calculating the reactions from the kinematic pairs it is applied the elastic linear calculation, using the relative displacements method noted in plukerian coordinates. The results of the numerical solving of this problem will be presented under the form of a diagrams and will be commented.
