Title (EN) VIBRATING APPARATUS FOR VIBRATORY COMPACTORS
(FR) DISPOSITIF VIBRANT POUR COMPACTEURS VIBRATOIRES
Abstract: front page image
(EN)A shaft arrangement (34) having a transversely displaceable weight member (42) relative to the shaft arrangement's longitudinal axis (B). The shaft arrangement (34) includes a housing structure (36) within compression structure (44) is arranged. The compression structure (44) extends through the housing structure (36) and connects to the displaceable weight member (42). An elastomeric member (50) is captured between the compression structure (44) and the housing structure (36) so as to resist transverse displacement of the weight member and the connected compression structure (44). The elastomeric member (50) maintains the weight member (42) and connected compression structure (44) in a rotatably balanced position relative to the longitudinal axis (B) for rotation speeds less than a predetermined amount. When the shaft arrangement (34) is rotated faster than such predetermined speed, the weight member (42) and connected compression structure (44) are transversely displaced so as to induce vibration in the shaft arrangement (34).
(FR)Dispositif d'arbre (34) possedant un organe de poids pouvant se deplacer transversalement (42) par rapport a l'axe longitudinal (B) du dispositif d'arbre. Le dispositif d'arbre (34) comprend une structure de boitier (36) a l'interieur de laquelle est logee une structure de compression (44). La structure de compression (44) s'etend au travers de la structure de boitier (36) et est reliee a l'organe mobile de poids (42). Un organe elastomere (50) est pris entre la structure de compression (44) et la structure de boitier (36) de maniere a s'opposer au deplacement transversal de l'organe de poids et de la structure de compression reliee (44). L'organe elastomere (50) maintient l'organe de poids (42) et la structure de compression reliee (44) dans une position rotative d'equilibre par rapport a l'axe longitudinal (B) en cas de vitesses de rotation inferieures a une valeur predeterminee. Lorsque le dispositif d'arbre (34) tourne plus vite que la vitesse predeterminee, l'organe de poids (42) et la structure de compression reliee (44) sont deplaces transversalement de maniere a provoquer une vibration dans le dispositif d'arbre (34).
