Title (EN) POWER TRANSFER DEVICE
(FR) DISPOSITIF DE TRANSFERT DE COUPLE
Abstract:
(EN) A power transmission device having a disengagement mechanism (7), whereby the device when not driven by a motor (5) may be operated manually. With motor drive, power is transmitted via a worm wheel (3) to a pawl (11 or 12) in a pawl mechanism, and therefrom further on to a boss (9) on which the pawls are pivotably mounted, said boss (9) being mechanically coupled to an apparatus (10) which is to be driven. The pawls (11, 12) are spring tensioned by means of a common arcuate spring (14). On manual operation, a shaft (15) mounted coaxially with the boss and rotatable relative thereto is turned in one or the other direction. The shaft (15) is provided with an arm (16) which, on contact with one of the pawls (11, 12), brings the pawl out of engagement with the worm wheel and causes rotation of the boss (9) and thereby of the apparatus (10), while the other pawl (12 or 11) on the influence of the spring (14) is caused to slip along an inner circumferential area (3'') of the worm wheel (3).
(FR) Cette invention concerne un dispositif de transmission de couple comprenant un mécanisme de désaccouplement (7), lequel dispositif, lorsqu'il n'est pas entraîné par un moteur (5), peut être actionné manuellement. Lorsqu'il est entraîné par un moteur, le couples est transmis, par l'intermédiaire d'une roue à vis (3), à un cliquet (11 ou 12) situé dans un mécanisme à cliquet, puis, de là, à un moyeu (9) sur lequel les cliquets sont montés pivotants, le moyeu (9) étant couplé mécaniquement à un appareil (10) devant être actionné. Les cliquets (11, 12) sont soumis à une tension par un ressort arqué commun (14). Lors de l'actionnement manuel, un arbre (15), monté de manière coaxiale par rapport au moyeu et pouvant entrer en rotation par rapport à celui-ci, tourne dans un sens s ou dans l'autre. Cet arbre (15) comporte un bras (16) qui, lorsqu'il entre en contact avec l'un des cliquets (11, 12), va désaccoupler le cliquet de la roue à vis et entraîner la rotation du moyeu (9) ainsi que celle de l'appareil (10), ceci tandis que l'autre cliquet (11 ou 12), qui est soumis à l'action du ressort (14), va glisser la long de la surface périphérique interne (3'') de la roue à vis (3).
