Veuillez nous fournir les donn\u00e9es de charge de vos conditions de travail. Nos ing\u00e9nieurs utiliseront un logiciel sp\u00e9cial pour calculer le facteur de s\u00e9curit\u00e9 et recommander le mod\u00e8le le plus \u00e9conomique et le plus s\u00fbr.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      Quel couple de renversement vos produits peuvent-ils supporter ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Cela d\u00e9pend du diam\u00e8tre sp\u00e9cifique.

Pour les \u00e9quipements dont le centre de gravit\u00e9 est \u00e9lev\u00e9 (comme les grues), veillez \u00e0 consulter nos courbes de charge statique pour vous assurer que le point de fonctionnement se trouve dans la zone de s\u00e9curit\u00e9 situ\u00e9e sous la courbe.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      Les engrenages peuvent-ils \u00eatre s\u00e9lectionn\u00e9s sans trempe ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Les engrenages de la norme sont g\u00e9n\u00e9ralement \u00e0 l'\u00e9tat tremp\u00e9 (260-290 HB). Si votre application implique une rotation secondaire \u00e0 haute fr\u00e9quence ou des charges d'impact \u00e9lev\u00e9es (telles que les excavateurs), nous vous recommandons fortement d'opter pour une trempe par induction de la surface de la dent (50-55 HRC) afin d'\u00e9viter la rupture de la dent ou une usure pr\u00e9matur\u00e9e.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      Quel type de graisse est n\u00e9cessaire pour ce petit palier d'orientation ?\n    <\/div>\n    <div class=\"faq-answer\">\n      La graisse extr\u00eame pression \u00e0 base de bisulfure de molybd\u00e8ne (MoS2) est recommand\u00e9e. Cette graisse peut former un film protecteur sur la surface de contact \u00e0 haute pression, ce qui convient parfaitement aux caract\u00e9ristiques de fonctionnement \u00e0 basse vitesse et \u00e0 usage intensif de la couronne d'orientation.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n     Pouvez-vous fournir une version \u00e9dent\u00e9e ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Oui. Nous proposons trois structures : avec dents internes, avec dents externes et sans dents. La version sans dents est g\u00e9n\u00e9ralement utilis\u00e9e dans des applications qui ne n\u00e9cessitent qu'un support rotatif mais qui sont entra\u00een\u00e9es par un m\u00e9canisme d'entra\u00eenement externe (tel qu'une tige de pouss\u00e9e), comme un lit d'examen m\u00e9dical ou certains supports photovolta\u00efques.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n     Quelles sont les exigences en mati\u00e8re de r\u00e9sistance des boulons de fixation du produit ?\n    <\/div>\n    <div class=\"faq-answer\">\n       Les boulons \u00e0 haute r\u00e9sistance de grade 10.9 ou 12.9 doivent \u00eatre utilis\u00e9s et pr\u00e9-serr\u00e9s \u00e0 l'aide d'une cl\u00e9 dynamom\u00e9trique conform\u00e9ment \u00e0 la valeur sp\u00e9cifi\u00e9e.
