INFLUENCE OF THE U-JOINTS ARRANGEMENT OF THE CARDAN SHAFTS ON VIBRATIONS AND MOVEMENT UNSYNCHRONIZATION

Salvadore-Mugurel BURCIU

Abstract


The paper explains through the presented mathematical model, the importance of cardan shaft phasing. In the case of the cardan shaft with perpendicular U-joints (compared to the one with coplanar U-joints), a high degree of non-uniformity of movement occurs which will lead to vibrations with negative implications on premature wear of the transmission as well as high discomfort. For construction with perpendicular U-joints, synchronism is recommended and the inclination angle of cardan shaft should not exceed 6 degrees, in which case the degree of non-uniformity of the movement would not exceed 3%.
