Catene a rulli di precisione a passo corto serie A<\/span><\/strong><\/p>\n

Le catene a rulli di precisione a passo corto della serie A sono ampiamente utilizzate in macchine agricole e nastri trasportatori. Queste catene sono progettate per resistere a carichi estremamente elevati. Per determinare la resistenza di una catena, \u00e8 necessario conoscerne la resistenza alla trazione. La resistenza a fatica \u00e8 altrettanto importante quanto la resistenza alla trazione. La resistenza a fatica \u00e8 determinata da diversi fattori, tra cui il tipo di acciaio, il trattamento termico dei componenti della catena, la fabbricazione dei fori di passo e l'intensit\u00e0 della pallinatura.<\/p>\n

Catene a rulli simplex e catene a boccole<\/strong><\/h2>\n

Le catene a rulli di precisione a passo corto della serie A (APC) sono disponibili in diverse misure. Ogni catena \u00e8 composta da una singola maglia di collegamento e da una o pi\u00f9 maglie disassate. Per la trasmissione di potenza ad alta velocit\u00e0, si raccomanda vivamente una maglia disassata a due passi. Queste catene sono disponibili in diversi materiali, tra cui acciaio e acciaio inossidabile.<\/p>\n

Vantaggi delle catene a rulli di precisione a passo corto serie A<\/strong><\/h2>\n

Hanno resistenza alla trazione.<\/h3>\n

Le catene a rulli di precisione a passo corto della serie A soddisfano gli standard ISO 9633 per la resistenza alla trazione. Hanno una resistenza alla trazione di 7 kN\/cm\u00b2. Sono utilizzate nella trasmissione di potenza meccanica, in applicazioni affini e nella produzione di catene di rotazione. Queste catene sono disponibili in configurazioni a fila singola, doppia e multipla, a seconda delle dimensioni e del passo. A seconda dell'ambiente di lavoro, sono disponibili con diverse finiture e lunghezze.<\/p>\n

Le catene a rulli di precisione a passo corto della serie A sono realizzate in acciaio o acciaio inossidabile. La resistenza minima a rottura di una catena in acciaio \u00e8 di 12500 x (passo, pollici). Alcune catene presentano una struttura con anelli a X o O-ring, che riduce notevolmente l'usura. Sono inoltre dotate di lubrificanti interni, iniettati sottovuoto durante la rivettatura delle catene. Tutte queste caratteristiche contribuiscono alla durata complessiva della catena, rendendola ideale per una variet\u00e0 di applicazioni.<\/p>\n

Hanno una resistenza alla fatica pari a 1\/9 della resistenza alla trazione della catena.<\/h3>\n

Generalmente, le catene a rulli vengono misurate in base alla loro resistenza alla trazione, ovvero la capacit\u00e0 di carico massima prima della rottura. Tuttavia, la resistenza a fatica \u00e8 altrettanto importante. La resistenza a fatica \u00e8 definita come il carico che la catena a rulli non \u00e8 in grado di sopportare per un periodo di tempo prolungato. La principale differenza tra le due \u00e8 che la resistenza alla trazione misura la capacit\u00e0 della catena una sola volta, mentre la resistenza a fatica riflette la capacit\u00e0 di carico nel tempo.<\/p>\n

La resistenza alla trazione minima di una catena a rulli di precisione a passo corto serie A \u00e8 di 12.500 x passo in pollici, un valore che rappresenta la resistenza ultima minima della catena. Le catene con denti a X o O-ring riducono notevolmente l'usura e sono pi\u00f9 durevoli di quelle senza. I lubrificanti interni vengono introdotti nella catena durante la rivettatura.<\/p>\n
