Cha\u00eenes \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court s\u00e9rie A<\/span><\/strong><\/p>\n

Les cha\u00eenes \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court de la s\u00e9rie A sont largement utilis\u00e9es dans les machines agricoles et les convoyeurs. Ces cha\u00eenes sont con\u00e7ues pour supporter des charges extr\u00eamement \u00e9lev\u00e9es. Pour d\u00e9terminer la r\u00e9sistance de votre cha\u00eene, il est n\u00e9cessaire de conna\u00eetre sa r\u00e9sistance \u00e0 la traction. La r\u00e9sistance \u00e0 la fatigue est tout aussi importante. Elle d\u00e9pend de plusieurs facteurs, notamment le type d'acier, le traitement thermique des composants de la cha\u00eene, la fabrication des trous de fixation et l'intensit\u00e9 du grenaillage.<\/p>\n

Cha\u00eenes \u00e0 rouleaux simplex et cha\u00eenes \u00e0 douilles<\/strong><\/h2>\n

Les cha\u00eenes \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court de la s\u00e9rie A (APC) sont disponibles en plusieurs dimensions. Chaque cha\u00eene est compos\u00e9e d'un maillon de liaison et d'un ou plusieurs maillons d\u00e9cal\u00e9s. Un maillon d\u00e9cal\u00e9 de deux pas est fortement recommand\u00e9 pour la transmission de puissance \u00e0 grande vitesse. Ces cha\u00eenes sont disponibles dans divers mat\u00e9riaux, notamment l'acier et l'acier inoxydable.<\/p>\n

Avantages des cha\u00eenes \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court de la s\u00e9rie A<\/strong><\/h2>\n

Elles poss\u00e8dent une r\u00e9sistance \u00e0 la traction.<\/h3>\n

Les cha\u00eenes \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court de la s\u00e9rie A r\u00e9pondent \u00e0 la norme ISO 9633 relative \u00e0 la r\u00e9sistance \u00e0 la traction. Leur r\u00e9sistance \u00e0 la traction est de 7 kN\/cm\u00b2. Elles sont utilis\u00e9es dans la transmission de puissance m\u00e9canique, les applications connexes et la fabrication de cha\u00eenes d'orientation. Ces cha\u00eenes sont disponibles en configurations \u00e0 une, deux ou plusieurs rang\u00e9es, selon leur taille et leur pas. En fonction de l'environnement de travail, elles sont propos\u00e9es avec diff\u00e9rents traitements de surface et longueurs.<\/p>\n

Les cha\u00eenes \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court de la s\u00e9rie A sont fabriqu\u00e9es en acier ou en acier inoxydable. La r\u00e9sistance minimale \u00e0 la rupture d'une cha\u00eene en acier est de 12\u00a0500 x (pas, pouces). Certaines cha\u00eenes sont dot\u00e9es d'une construction \u00e0 joints toriques (X-ring ou O-ring), ce qui r\u00e9duit consid\u00e9rablement l'usure. Elles int\u00e8grent \u00e9galement un syst\u00e8me de lubrification sous vide lors du rivetage. L'ensemble de ces caract\u00e9ristiques contribue \u00e0 la long\u00e9vit\u00e9 de la cha\u00eene, la rendant id\u00e9ale pour de nombreuses applications.<\/p>\n

Leur r\u00e9sistance \u00e0 la fatigue est \u00e9gale \u00e0 1\/9 de la r\u00e9sistance \u00e0 la traction de la cha\u00eene.<\/h3>\n

G\u00e9n\u00e9ralement, les cha\u00eenes \u00e0 rouleaux sont \u00e9valu\u00e9es selon leur r\u00e9sistance \u00e0 la traction, qui correspond \u00e0 la charge maximale qu'elles peuvent supporter avant rupture. Cependant, la r\u00e9sistance \u00e0 la fatigue est tout aussi importante. Elle se d\u00e9finit comme la charge que la cha\u00eene ne peut supporter sur une p\u00e9riode prolong\u00e9e. La principale diff\u00e9rence entre les deux r\u00e9side dans le fait que la r\u00e9sistance \u00e0 la traction mesure la capacit\u00e9 de la cha\u00eene ponctuellement, tandis que la r\u00e9sistance \u00e0 la fatigue refl\u00e8te sa capacit\u00e9 de charge au fil du temps.<\/p>\n

La r\u00e9sistance \u00e0 la traction minimale d'une cha\u00eene \u00e0 rouleaux de pr\u00e9cision \u00e0 pas court de la s\u00e9rie A est de 12\u00a0500 x pas en pouces, valeur qui repr\u00e9sente la r\u00e9sistance ultime minimale de la cha\u00eene. Les cha\u00eenes \u00e0 dents en X ou en O r\u00e9duisent consid\u00e9rablement l'usure et sont plus durables que celles qui n'en sont pas dot\u00e9es. Des lubrifiants internes sont introduits dans la cha\u00eene lors du rivetage.<\/p>\n
