Le chanfreinage est un terme d'ing\u00e9nierie m\u00e9canique. Afin d'\u00e9liminer les bavures sur les pi\u00e8ces caus\u00e9es par l'usinage et de faciliter l'assemblage des pi\u00e8ces, le chanfreinage est g\u00e9n\u00e9ralement r\u00e9alis\u00e9 \u00e0 l'extr\u00e9mit\u00e9 de la pi\u00e8ce.<\/p>\n

\"Chanfrein<\/h1>\n

Le chanfreinage est omnipr\u00e9sent dans notre vie : cadres de t\u00e9l\u00e9phones portables, portes tremp\u00e9es, vases, etc.<\/p>\n

\"le<\/p>\n

En g\u00e9n\u00e9ral, la fonction du chanfreinage<\/a><\/strong><\/span> est d'enlever les bavures et de les rendre belles.<\/p>\n

Cependant, les chanfreins sp\u00e9cifiquement indiqu\u00e9s dans les dessins sont g\u00e9n\u00e9ralement des exigences pour le processus d'installation, comme le guide d'installation des roulements. Il existe \u00e9galement des chanfreins en arc (ou transitions en arc) qui peuvent \u00e9galement r\u00e9duire la concentration des contraintes et renforcer l'arbre. Le r\u00f4le de la r\u00e9sistance de la pi\u00e8ce.<\/p>\n

En outre, il peut \u00e9galement faciliter l'assemblage, g\u00e9n\u00e9ralement avant la fin de la transformation.<\/p>\n

\"<\/p>\n

Sur les pi\u00e8ces de machines agricoles, les faces d'extr\u00e9mit\u00e9 des raccords circulaires et des trous ronds sont souvent chanfrein\u00e9es \u00e0 environ 45\u00b0.<\/p>\n

Ces chanfreins ont de nombreuses fonctions. Ils doivent \u00eatre soigneusement contr\u00f4l\u00e9s et pleinement utilis\u00e9s lors des op\u00e9rations de maintenance. Dans le cas contraire, cela entra\u00eenera de nombreuses difficult\u00e9s pour l'entretien des machines agricoles, voire des d\u00e9faillances inattendues. Par exemple, avant le processus de moulage de petites pi\u00e8ces telles que les boulons, un chanfreinage est \u00e9galement effectu\u00e9 pour faciliter l'entr\u00e9e dans le moule.<\/p>\n

Quelle est la fonction du chanfreinage des roulements ?<\/h2>\n

1. l'acier \u00e0 roulements doit \u00eatre chanfrein\u00e9 lors de l'usinage grossier avant le traitement thermique. De cette mani\u00e8re, lors du traitement thermique du mat\u00e9riau, les contraintes sont lib\u00e9r\u00e9es et la structure organisationnelle interne est redistribu\u00e9e, ce qui r\u00e9duit le risque de fissures.<\/p>\n

2. le chanfreinage et l'\u00e9bavurage font que le produit n'est pas tranchant et ne coupe pas l'utilisateur.<\/p>\n

3. il joue un r\u00f4le de guidage et de positionnement lors de l'assemblage.<\/p>\n

En g\u00e9n\u00e9ral, le chanfrein ext\u00e9rieur de la bague ext\u00e9rieure du roulement et le chanfrein int\u00e9rieur de la bague int\u00e9rieure sont des angles arrondis. En plus d'\u00e9viter efficacement les contraintes de contact, le plus important est de faciliter l'installation. Les coins arrondis garantissent un bon ajustement transitoire.<\/p>\n

En particulier au cours du processus de fabrication des roulements, la surface de positionnement de l'arbre et du trou de l'arbre, c'est-\u00e0-dire l'\u00e9paulement de l'arbre et la partie de l'\u00e9paulement de la port\u00e9e du roulement, la taille du chanfrein de cette partie influe directement sur la possibilit\u00e9 d'installer correctement le roulement.<\/p>\n

\"Chanfrein<\/p>\n

L'image ci-dessus montre que le roulement est install\u00e9 entre la bo\u00eete d'essieu et l'arbre. Les chanfreins sont plus grands que les chanfreins entre la bo\u00eete de roulement et l'\u00e9paulement de l'arbre. Le chanfrein du roulement doit \u00eatre plus grand que cet arc pour garantir que le roulement s'adapte \u00e0 l'arbre. vers la surface de positionnement.<\/p>\n

\"Chanfrein<\/p>\n

Comme le montre la figure ci-dessus, lorsque le chanfrein du roulement est plus petit que le chanfrein de la bo\u00eete de roulement et de l'\u00e9paulement de l'arbre, il ne peut pas \u00eatre assembl\u00e9 en place, ce qui peut facilement entra\u00eener une concentration de contraintes au niveau du chanfrein du roulement, un basculement de l'assemblage et l'impossibilit\u00e9 de faire correspondre d'autres pi\u00e8ces appari\u00e9es.<\/p>\n

Par cons\u00e9quent, l'ajustement du chanfrein doit \u00eatre pleinement pris en compte lors du processus d'assemblage du roulement.<\/p>","protected":false},"excerpt":{"rendered":"
