Title (EN) SHAFT DEFLECTOR WITH A DEFLECTION ADJUSTING MECHANISM
(FR) DISPOSITIF DE MODIFICATION DE DIRECTION D'ARBRE DOTÉ D'UN MÉCANISME DE RÉGLAGE DE MODIFICATION DE DIRECTION
Abstract:
(EN) An apparatus including a housing defining a housing bore and a shaft extending within the housing bore. The shaft is deflectable and tiltable within the housing bore. The apparatus further includes a fulcrum for tiltably supporting the shaft within the housing bore, a shaft deflector contained within the housing for providing a deflection of the shaft within the housing bore so that the shaft tilts about the fulcrum, and a deflection adjusting mechanism. The deflection adjusting mechanism includes a biasing device which responds to an external force exerted on the shaft in order to adjust the deflection of the shaft provided by the shaft deflector and thereby provide an adjusted deflection of the shaft.
(FR) L'invention concerne un appareil comprenant un boîtier délimitant un alésage de logement et un arbre s'étendant à l'intérieur de l'alésage de logement. L'arbre peut être dévié et incliné à l'intérieur de l'alésage de logement. L'appareil comprend en outre un point d'appui pour soutenir l'arbre de manière inclinable à l'intérieur de l'alésage de boîtier, un dispositif de modification de direction d'arbre contenu à l'intérieur du boîtier pour fournir une modification de direction de l'arbre à l'intérieur de l'alésage de boîtier de telle sorte que l'arbre s'incline autour du pivot, et un mécanisme de réglage de modification de direction. Le mécanisme de réglage de modification de direction comprend un dispositif de sollicitation qui répond à une force externe exercée sur l'arbre afin de régler la modification de direction de l'arbre fournie par le dispositif de modification de direction d'arbre et de fournir ainsi une modification de direction réglée de l'arbre.
