Que \u00e9 mellor, f\u00edos grosos ou finos? Esta \u00e9 unha pregunta que se escoita con frecuencia na nosa empresa\u00a0relativa tanto \u00e1s inserci\u00f3ns como aos fixadores roscados macho, e opinamos que os f\u00edos grosos te\u00f1en moitas vantaxes e vantaxes sobre os finos.<\/p>\n

F\u00edos grosos<\/b><\/strong><\/h2>\n

Os f\u00edos grosos son m\u00e1is duradeiros e te\u00f1en unha maior resistencia ao decapado e ao enroscado cruzado. A altura de cada rosca \u00e9 maior que a rosca fina correspondente, polo que hai m\u00e1is material entre cada rosca facendo que o enganche dos flancos sexa maior.<\/p>\n

Os f\u00edos grosos son menos susceptibles de ser cortados ou danados, polo que non te\u00f1en que ser \"manexados con coidado\" tanto como os finos. Un corte nun f\u00edo fino pode causar m\u00e1is problemas proporcionalmente debido \u00e1 escasa profundidade do f\u00edo, p. ex. calibre ou montaxe.<\/p>\n

Os fixadores de rosca grosa inst\u00e1lanse moito m\u00e1is r\u00e1pido que os de rosca fina. Un parafuso\u00a01\/2\"-13\u00a0UNC ensambla en 65% do tempo que levar\u00eda montar un parafuso\u00a01\/2\"-20UNF. O parafuso de 1\/2\"-20UNF avanza unha polgada en 20 revoluci\u00f3ns, mentres que o parafuso de 1\/2\"-13UNC avanza unha polgada en s\u00f3 13 revoluci\u00f3ns.<\/p>\n

Os f\u00edos grosos non se ven afectados pola acumulaci\u00f3n de placas tanto como os finos. A mesma cantidade de chapado nun f\u00edo groso consumir\u00eda unha maior cantidade do margen de chapado nun f\u00edo fino. Os f\u00edos finos experimentan m\u00e1is problemas de calibre e montaxe debido \u00e1 acumulaci\u00f3n de placas que os f\u00edos grosos, xa que hai menos material entre cada flanco de rosca.<\/p>\n

Cando se usan inserci\u00f3ns de bloqueo ou outros suxeidores con rosca, os f\u00edos grosos son moito menos propensos a sufrir irritaci\u00f3n que os finos. Os f\u00edos finos te\u00f1en m\u00e1is rotaci\u00f3ns como comentamos anteriormente e isto, unido aos axustes de di\u00e1metro de paso m\u00e1is pr\u00f3ximos dos f\u00edos finos, aumenta a tendencia de que os f\u00edos finos experimenten abrasi\u00f3ns.<\/p>\n

F\u00edos finos<\/b><\/strong><\/h2>\n

Os parafusos de rosca fina son m\u00e1is resistentes que os correspondentes parafusos de rosca grosa da mesma dureza. Isto \u00e9 tanto en tensi\u00f3n como en cizalla debido a que os parafusos roscados finos te\u00f1en unha \u00e1rea de tensi\u00f3n de tracci\u00f3n lixeiramente maior e un di\u00e1metro menor.<\/p>\n

Os f\u00edos finos te\u00f1en menos tendencia a afrouxarse baixo a vibraci\u00f3n debido a que te\u00f1en un \u00e1ngulo de h\u00e9lice menor que os f\u00edos grosos. As bobinas de agarre de inserci\u00f3n de bloqueo de rosca fina son m\u00e1is flexibles que as bobinas de agarre de inserci\u00f3n de rosca gruesa do tama\u00f1o correspondente e te\u00f1en menos probabilidades de levar un conxunto en condici\u00f3ns de vibraci\u00f3n.<\/p>\n

Os f\u00edos finos debido ao seu paso m\u00e1is fino permiten axustes m\u00e1is finos naquelas aplicaci\u00f3ns que precisan desta caracter\u00edstica.<\/p>\n

Os f\u00edos finos p\u00f3dense tocar m\u00e1is facilmente en materiais dif\u00edciles de tocar e en secci\u00f3ns de paredes finas.<\/p>\n

As roscas finas requiren menos par de apriete para desenvolver precargas equivalentes aos tama\u00f1os de parafusos de rosca grosa correspondentes.<\/p>\n

Resumo<\/b><\/strong><\/h2>\n

Normalmente especif\u00edcase unha rosca grosa para a maior\u00eda das aplicaci\u00f3ns industriais a menos que exista unha raz\u00f3n convincente para non facelo. As aplicaci\u00f3ns militares e aeroespaciais usan xeralmente f\u00edos grosos en tama\u00f1os 8-32 e inferiores. Nos fixadores m\u00e9tricos, xeralmente os tama\u00f1os grosos son os m\u00e1is usados, sendo os pasos m\u00e1is finos menos dispo\u00f1ibles.<\/p>","protected":false},"excerpt":{"rendered":"
