THE TECHNICAL AND GEOMETRICAL DEVIATIONS OF CARDAN JOINT MECHANISM

During the manufacturing and montage process of cardan transmissions, at the component elements may inevitable appear technical (geometrical) deviations. These deviations lead to the changine of kinematic parameters of the mechanism.For the determination of these changes it is first necessary to identify these deviations and give them a geometrical interpretation. By having as a purpose the identifying of both angular and axis deviations, over the kinematic parameters of the cardan joint mechanism, it is necessary to consider the cardan joint, not as a spherical quadrilateral but as a particular case of RCCC mechanism where by C, R was noted the cylindrical kinematic pair respectively the rotation kinematic pair
