Abstract
(DE)
Eine Verstelleinrichtung zur Veränderung eines Funktionsparameters bei einem Schwingungserreger, der weningstens eine von einer drehantreibbaren Welle (14, 16) getragene, rotierbare Unwucht (18, 24) aufweist, ist mit einem zur Veränderung eines Funktionsparameters auf der Welle (14, 16) verdrehbar gelagerten Stellorgan (22, 30) versehen und mit einem dem Stellorgan (22, 30) zugeordneten, innerhalb der Welle (14, 16) in axialer Richtung verstellbaren und mit der Welle rotierend angeordneten Stellbolzen (48). Der durch einen ansteuerbaren, nicht rotierenden Stempel (34) betätigbare Stellbolzen (48) und der Stempel (34) liegen in Achsrichtung der Welle (14, 16) derart aneinander an, dass sich eine ballige Kontur (44) und eine die Rotationsachse (40) der Welle (14, 16) rechtwinklig querende Gegenfläche (50) in deren auf die Rotationsachse (40) bezogenem Zentrum berühren.
(EN)
A readjusting device used to modify the functional parameters of an oscillator which comprises at least one rotatable unbalanced mass (18,24) which is supported by a rotationally driveable shaft (14,16) is provided with a rotationally mounted adjusting member (22,23) on said shaft in order to modify the above-mentioned functional parameters and with an adjusting pin (48) which is associated with the adjusting member (22, 30), can be readjusted in an axial direction inside the shaft (14, 16) and which is arranged in such a way that it can rotate with the shaft. The adjusting pin (48) which can be actuated by a controllable, non-rotating stamp (35) and said stamp are disposed in an axial direction of the shaft (14,16) in such a way that a crowned contour (44) and a counter surface (50) traversing the rotational axis (40) of the shaft (14,16) at a right angle touch each other in the center thereof relative to the axis of rotation (40).
(FR)
L'invention concerne un dispositif de réglage pour modifier un paramètre de fonction sur un vibreur qui comporte au moins un balourd (18, 24) pivotant, porté par un arbre (14, 16) entraîné en rotation. Ce dispositif est pourvu d'un organe de réglage (22, 30), monté pivotant sur l'arbre (14, 16) et destiné à modifier un paramètre de fonction, et d'un boulon de réglage (48), associé à l'organe de réglage (22, 30), monté pivotant avec l'arbre et réglable dans le sens axial à l'intérieur de cet arbre (14, 16). Le boulon de réglage (48) actionné par un poinçon (34) mobile non pivotant et ce poinçon (34) sont disposés dans l'axe de l'arbre (14, 16) de manière adjacente telle qu'un profil bombé (44) et une surface antagoniste (50) perpendiculairement transversale à l'axe de rotation (40) de l'arbre (14, 16) se touchent au centre de ladite surface relativement à l'axe de rotation (40).
