Title (EN) A METHOD AND AN APPARATUS FOR JOINING CRANK SHAFTS
(FR) PROCEDE ET APPAREIL D"ASSEMBLAGE DE VILEBREQUINS
Abstract: front page image
(EN)Method and apparatus for joining within accurate geometrical tolerances two crank shaft halves (D, M) via a crank pin (6) into a complete crank shaft (1). Each crank shaft half has a shaft (2, 3) which over a flange (12) continues into a crank disk (4, 5) in at least one of which there is at an accurate distance from the shaft made a through bore (7 and 8, respectively) for the crank pin. The crank pin may be separate or integral with one crank shaft half. The crank shaft halves are joined in that the crank pin is pressed into said bore(s) by the application of a press force (P) to the outer sides of the crank disks. During the pressing-in of the crank pin (6) into the bores (7, 8) of the crank disks the shafts (2, 3) of the crank shaft halves are carefully aligned in dependence of the accurate tolerances and are retained relative each other within said tolerances, while the crank pin in turn is allowed to be lined up by the bores of the crank disks, taking advantage of the possibilities of inclination of the crank pin relative to the crank disks and within the deformation zone of said press fit joint.
(FR)Procede et appareil d"assemblage de deux moities de vilebrequins (D, M) avec des tolerances geometriques precises via un maneton (6) en un vilebrequin complet (1). Chaque moitie de vilebrequin possede un arbre (2, 3) ayant une bride (12) qui se prolonge en plateau-manivelle (4, 5) dans au moins l"un deux, et a une distance precise de l"arbre, est amenage un alesage traversant (7, 8 respectivement) pour le maneton. Le maneton peut etre separe ou solidaire d"une moitie de vilebrequin. Les moities de vilebrequin sont assemblees en forcant le maneton dans le ou les alesages (S) en appliquant une force de pression (P) sur les cotes exterieurs des plateaux-manivelles. Pendant l"emmanchement a force du maneton (6) dans les alesages (7, 8) des plateaux-manivelles, les arbres (2, 3) des moities de vilebrequins sont soigneusement alignes en fonction des tolerances precises et sont maintenus l"un par rapport a l"autre dans ces tolerances, tandis que le maneton peut a son tour etre aligne par les alesages des plateaux-manivelles, profitant des possibilites d"inclinaison du maneton par rapport aux plateaux-manivelles et dans la zone de deformation de cet assemblage a emmanchement a force.
