Abstract

Ce dispositif peut être préréglé et se bloquer ensuite si des forces de rotation brutales ou progressives lui sont appliquées. Il comprend un premier organe 8 reçu au moins en partie dans un second organe 6 dont la rotation dans un sens ou dans l'autre provoque celle de l'autre organe, autour du même axe. Des galets 3 coopèrent avec des surfaces de coincement (surface interne d'un manchon 2 et faces planes d'un organe 8) pour empêcher la rotation de l'organe 6 sous l'effet d'une rotation de l'organe 8, les galets étant agencés par paires autour de l'axe et le nombre de paires supérieur à deux. Les forces nécessaires pour empêcher la rotation sont ainsi réparties de façon à peu près égale entre les galets respectifs des paires de galets.This device can be preset and then lock if sudden or progressive rotational forces are applied to it. It comprises a first member 8 received at least in part in a second member 6 whose rotation in one direction or the other causes that of the other member, around the same axis. Rollers 3 cooperate with wedging surfaces (internal surface of a sleeve 2 and plane faces of a member 8) to prevent the rotation of the member 6 under the effect of a rotation of the member 8, the rollers being arranged in pairs around the axis and the number of pairs greater than two. The forces necessary to prevent rotation are thus distributed approximately evenly between the respective rollers of the pairs of rollers.
