En outre, il est n\u00e9cessaire de confirmer que la hauteur de l'engrenage est conforme \u00e0 l'original afin de garantir un engr\u00e8nement correct avec le pignon.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      Q2 : Quelle est la fr\u00e9quence de remplissage de graisse de cette couronne d'orientation ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Dans les conditions normales de fonctionnement de la grue, il est recommand\u00e9 d'ajouter de la graisse toutes les 100 heures. En cas de travail dans des environnements tropicaux chauds ou poussi\u00e9reux, il est recommand\u00e9 de r\u00e9duire le remplissage \u00e0 une fois toutes les 50 heures jusqu'\u00e0 ce que l'ancienne graisse soit expuls\u00e9e de la l\u00e8vre d'\u00e9tanch\u00e9it\u00e9.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      Q3 : Quelle est la diff\u00e9rence sp\u00e9cifique entre le mat\u00e9riau 42CrMo et le mat\u00e9riau 50Mn ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Le 42CrMo est un acier de construction alli\u00e9, qui pr\u00e9sente une meilleure trempabilit\u00e9 et une meilleure r\u00e9sistance aux chocs, et convient aux grues lourdes qui supportent d'\u00e9normes charges d'impact. 50Mn est un acier de construction au carbone, dont la duret\u00e9 superficielle est \u00e9lev\u00e9e, mais dont la t\u00e9nacit\u00e9 du c\u0153ur est m\u00e9diocre, et qui convient mieux aux \u00e9quipements de levage de petite et moyenne taille \u00e0 charge stable.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n      Q4 : Pourquoi ma couronne d'orientation a-t-elle un bruit anormal peu de temps apr\u00e8s son utilisation ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Les bruits anormaux sont g\u00e9n\u00e9ralement dus \u00e0 une lubrification insuffisante, \u00e0 une base de montage in\u00e9gale entra\u00eenant une d\u00e9formation du chemin de roulement, ou \u00e0 un jeu d'engr\u00e8nement trop faible. Si le bruit est un bruit d'impact m\u00e9tallique net, il se peut qu'il y ait des impuret\u00e9s dans le chemin de roulement ou que la cage soit endommag\u00e9e ; il faut donc arr\u00eater la machine imm\u00e9diatement pour l'inspecter.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n     Q5 : Les boulons de fixation peuvent-ils \u00eatre r\u00e9utilis\u00e9s ?\n    <\/div>\n    <div class=\"faq-answer\">\n      Ce n'est pas le cas. La grue \u00e0 palier d'orientation est soumise \u00e0 des charges altern\u00e9es, et l'ancien boulon peut avoir produit une d\u00e9formation permanente en traction ou des dommages dus \u00e0 la fatigue. Pour des raisons de s\u00e9curit\u00e9, le remplacement des roulements doit \u00eatre synchronis\u00e9 avec le remplacement de nouveaux boulons \u00e0 haute r\u00e9sistance de grade 10.9 ou 12.9.\n    <\/div>\n  <\/div>\n\n  <div class=\"faq-item\">\n    <div class=\"faq-question\">\n     Q6 : Comment vos produits pr\u00e9viennent-ils la corrosion pendant le transport ?\n    <\/div>\n    <div class=\"faq-answer\">\n       Nous appliquons une huile antirouille \u00e9paisse sur la surface du produit avant qu'il ne quitte l'usine, nous l'enveloppons d'un film antirouille VCI de qualit\u00e9 industrielle et la couche ext\u00e9rieure est emball\u00e9e dans une bo\u00eete en bois en contreplaqu\u00e9.
