Que sont les spires de vis segment\u00e9es ?<\/h2>

Une spire segment\u00e9e est un \u00e9l\u00e9ment h\u00e9lico\u00efdal form\u00e9 individuellement. Plusieurs \u00e9l\u00e9ments compatibles peuvent \u00eatre assembl\u00e9s sur un arbre pour constituer une vis. Il s\u2019agit d\u2019un composant, et non d\u2019un convoyeur complet : ajustement sur l\u2019arbre, assemblage, soudage et entra\u00eenement n\u00e9cessitent une \u00e9tude distincte.<\/p>

Applications et choix de la mati\u00e8re<\/h2>

Pour remplacer des spires us\u00e9es ou assembler une nouvelle vis, pr\u00e9cisez le produit transport\u00e9, l\u2019abrasion, la corrosion et les conditions de service. Acier carbone, inox ou t\u00f4le r\u00e9sistante \u00e0 l\u2019usure peuvent \u00eatre \u00e9tudi\u00e9s. La nuance, l\u2019\u00e9paisseur, la compatibilit\u00e9 et la disponibilit\u00e9 sont confirm\u00e9es au devis. Le nom du mat\u00e9riau ne constitue pas une conformit\u00e9 alimentaire ou ATEX.<\/p>

Dimensions \u00e0 pr\u00e9ciser<\/h2>

La commande repose sur la g\u00e9om\u00e9trie finie. Le tableau ci-dessous sert \u00e0 pr\u00e9parer la demande ; il ne constitue ni une liste de stock ni une plage de fabrication garantie. Les dimensions et tol\u00e9rances sont confirm\u00e9es sur plan.<\/p>

Spires segment\u00e9es ou continues ?<\/h2>

Les spires segment\u00e9es sont des pi\u00e8ces form\u00e9es s\u00e9par\u00e9ment. Les spires continues sont obtenues sous forme de spirale ininterrompue \u00e0 partir de bande. Le choix d\u00e9pend du plan, de la mati\u00e8re, de l\u2019\u00e9paisseur et du mode d\u2019assemblage. Le tableau des spires continues ne d\u00e9finit pas les spires segment\u00e9es.<\/p>

Demander un devis de fourniture<\/h2>

Envoyez un plan ou des photos nettes, le diam\u00e8tre ext\u00e9rieur fini, l\u2019al\u00e9sage ou le diam\u00e8tre de l\u2019arbre, le pas, l\u2019\u00e9paisseur, le sens de l\u2019h\u00e9lice, la nuance et la quantit\u00e9. Pour un remplacement, identifiez l\u2019arbre existant et la zone us\u00e9e. Pr\u00e9cisez si vous souhaitez des spires seules ou une vis assembl\u00e9e ; l\u2019assemblage fait l\u2019objet d\u2019un devis distinct.<\/p>","protected":false},"excerpt":{"rendered":"Segments h\u00e9lico\u00efdaux individuels pour la remise en \u00e9tat des convoyeurs \u00e0 vis et les nouveaux assemblages sur arbre. eQUIP fournit les spires selon votre plan et les besoins de votre application.","protected":false},"featured_media":5398,"template":"","meta":[],"products-category":[35],"class_list":["post-5402","products","type-products","status-publish","has-post-thumbnail","hentry","products-category-convoyeurs-a-vis-et-doseurs"],"yoast_head":"\nSpires de vis segment\u00e9es | Secteurs de spire | eQUIP<\/title>\n<meta name=\"description\" content=\"Spires de vis segment\u00e9es pour r\u00e9paration et assemblage.
