Les chapes d’attelage se composent de deux brides qui sont assembl\u00e9es. Sur l’une des brides se trouvent des boulons r\u00e9partis uniform\u00e9ment sur un cercle. La deuxi\u00e8me bride dispose d’\u00e9videments adapt\u00e9s dans lesquels les boulons s’engagent. Des \u00e9l\u00e9ments en caoutchouc sont mont\u00e9s sur les boulons. Ils sont soumis \u00e0 une usure normale et doivent donc \u00eatre remplac\u00e9s \u00e0 intervalles r\u00e9guliers. <\/p>

Le couple est transmis par les boulons, les \u00e9l\u00e9ments en caoutchouc servant \u00e0 amortir la transmission irr\u00e9guli\u00e8re de la force. Les accouplements \u00e0 boulons peuvent \u00eatre enfich\u00e9s axialement, ce qui facilite consid\u00e9rablement le montage et le d\u00e9montage. Il a un effet d’amortissement des vibrations et peut \u00eatre utilis\u00e9 \u00e0 des temp\u00e9ratures comprises entre -25 degr\u00e9s et +100 degr\u00e9s Celsius. Les diam\u00e8tres d’arbre sont g\u00e9n\u00e9ralement compris entre 10 mm et 450 mm, et la courbe caract\u00e9ristique du ressort est progressive. <\/p>

Le d\u00e9calage angulaire est compris entre 0,4 et 2 degr\u00e9s, le jeu de torsion est faible. Les accouplements \u00e0 boulons sont r\u00e9sistants aux perforations, les couples se situent entre 40 Nm et 1000 kNm. Les vitesses de rotation se situent entre 5000 et 500 par minute, selon la taille de l’accouplement. Les accouplements \u00e0 boulons sont disponibles en diff\u00e9rents mod\u00e8les et tailles avec un diam\u00e8tre maximal de 104 cm. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Les accouplements \u00e0 boulons sont utilis\u00e9s dans les domaines les plus divers de la construction m\u00e9canique. Les accouplements traditionnels \u00e0 boulons sont par exemple utilis\u00e9s dans la sylviculture et l’agriculture. En raison de ses caract\u00e9ristiques, l’accouplement \u00e0 boulons offre une transmission tr\u00e8s s\u00fbre du couple. Les vibrations et les chocs sont efficacement amortis. En outre, les accouplements de ce type sont souvent utilis\u00e9s pour les souffleries et les rotors. Ils peuvent \u00eatre install\u00e9s dans des aci\u00e9ries, des centrales hydro\u00e9lectriques ou des centrales \u00e0 b\u00e9ton. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

En raison de leur forme et des mat\u00e9riaux utilis\u00e9s, les chapes d’attelage sont tr\u00e8s bien adapt\u00e9es aux charges dynamiques. Pour les grands attelages \u00e0 boulons, qui doivent offrir une grande r\u00e9sistance \u00e0 l’usure et ne pas se d\u00e9former m\u00eame en cas de chocs violents, on utilise par exemple les mat\u00e9riaux suivants : <\/p>

  • Le stigmate est constitu\u00e9 de fonte et de graphite sph\u00e9ro\u00efdal.<\/p><\/li>

  • Les boulons sont en acier et peuvent \u00eatre remplac\u00e9s sur de nombreux mod\u00e8les lors de l’entretien.<\/p><\/li>

  • Les \u00e9l\u00e9ments \u00e9lastiques sont embo\u00eet\u00e9s et sont par exemple en polyur\u00e9thane. Ils sont \u00e9galement interchangeables et disposent d’une tr\u00e8s grande \u00e9lasticit\u00e9 aux chocs. <\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
