Hello,<\/p>\n

comme promis voici une petite explication visuelle du fonctionnement du mouvement en DEC de mon vieux bidule.<\/p>\n

Donc…il s’agit d’un syst\u00e8me \u00e0 fouche. Le tube serrurier est pos\u00e9 sur la fourche via deux paliers. Entre le tube et la fourche il y a le \u00ab\u00a0bras d’entrainement\u00a0\u00bb sur lequel se trouve le moteur, la vis sans fin et son \u00e9crou. Ce dernier est fix\u00e9 au tube via une glissi\u00e8re \u00e0 l’\u00e9crou tracteur.<\/p>\n

\"\" <\/a>\"\"<\/a><\/p>\n

La partie ronde du bras est ins\u00e9r\u00e9e dans un syst\u00e8me d’\u00e9trier qui lorsqu’on le sert \u00e0 l’aide de la poign\u00e9e rend le bras solidaire de la fourche. Il est alors coinc\u00e9 fixe par rapport \u00e0 la fourche et le seul moyen de faire bouger le tube en DEC est d’actionner le moteur. Soit via la raquette manuelle soit via le pc avec un pilote ascom ou encore avec le logiciel d’autoguidage.<\/p>\n

\"\" <\/a>\"\"<\/a><\/p>\n

Voil\u00e0, comme j’avais dit c’est simple.\u00a0 Juste plus facile \u00e0 visualiser avec quelques images ;o)<\/p>\n

Finalement \u00e7a ne guide pas si mal pour un syst\u00e8me bricol\u00e9.<\/p>\n
