Title
(EN) MOVEMENT FOR A TIMEPIECE WITH EQUALIZING WINDING MECHANISM
(FR) MOUVEMENT POUR PIECE D'HORLOGERIE A REMONTOIR D'EGALITE
Abstract
(EN) A movement for a timepiece comprising a first energy source (9) intended to sustain the oscillatory movement of a mechanical oscillator comprising a resonator and an escapement, through a finishing gear train that forms, between said first energy source (9) and the escapement a first drive line, said movement further comprising a regulating device (14) intended to control said escapement. The regulating device (14) comprises a stop wheel (16) kinematically connected to said finishing gear train and intended to effect a rotational movement periodically, a control cam (24) driven in rotation and secured to a control wheel (20), a locking device, controlled by said cam (24) for locking said stop wheel (16) and periodically releasing it, and an elastic member (18) intended periodically to store energy from said first energy source (9) and restore it to said oscillator. In addition, said regulating device (14) further comprises transmission means and means of regulating said control wheel (20), said transmission means and said regulating means forming, with the control wheel (20), a second drive line that does not include said finishing gear train, said transmission means being arranged to supply energy to said second drive train, and said regulating means being designed periodically to release said control wheel (20) and allow the transmission means to drive the rotation of said control wheel (20).
(FR) Mouvement pour pièce d'horlogerie comprenant une première source d'énergie (9), destinée à entretenir le mouvement oscillant d'un oscillateur mécanique comportant un résonateur et un échappement, par le biais d'un rouage de finissage formant entre ladite première source d'énergie (9) et l'échappement une première chaîne cinématique, ledit mouvement comprenant en outre un dispositif de régulation (14) destiné à commander ledit échappement. Le dispositif de régulation (14) comporte une roue d'arrêt (16) reliée cinématiquement audit rouage de finissage et destinée à effectuer un mouvement de rotation de manière périodique, une came de commande (24) entraînée en rotation et solidaire d'une roue de commande (20), un dispositif de verrouillage de ladite roue d'arrêt (16) commandé par ladite came (24) pour la libérer périodiquement, et un organe élastique (18) destiné à stocker périodiquement de l'énergie à partir de ladite première source d'énergie (9), pour la restituer audit oscillateur. De plus, ledit dispositif de régulation (14) comporte en outre des moyens de transmission et des moyens de régulation de ladite roue de commande (20), lesdits moyens de transmission et lesdits moyens de régulation formant avec la roue de commande (20) une deuxième chaîne cinématique ne comprenant pas ledit rouage de finissage, lesdits moyens de transmission étant agencés pour alimenter en énergie ladite deuxième chaîne cinématique, et lesdits moyens de régulation étant agencés pour libérer périodiquement ladite roue de commande (20) et permettre aux moyens de transmission d'entraîner ladite roue de commande (20) en rotation.
