Un cuscinetto a sfere a contatto obliquo è composto da due anelli con piste a sezione asimmetrica. Poiché un carico radiale tende a separare i due anelli in direzione assiale, essi vengono solitamente utilizzati a coppie. I cuscinetti a contatto obliquo meglio sostengono i carichi radiali ed assiali combinati, avendo scelto l’angolo di contatto più proporzionato al rapporto tra i carichi. Quanto maggiore è l’angolo di contatto (tipicamente tra i 10° ed i 45°) tanto maggiore è il carico assiale sostenibile e minore quello radiale. Nelle applicazioni ad alta velocità di rotazione come turbine, motori jet ed apparecchiature dentali, la forza centrifuga che agisce sulle sfere modifica l’angolo effettivo di contatto con le piste di rotolamento. Materiale ceramico come il nitruro di silicio viene regolarmente utilizzato in queste applicazioni grazie alla sua minor densità (40% rispetto all’acciaio), consentendo di ridurre significativamente la forza centrifuga e di funzionare bene alle alte temperature. I materiali ceramici si usurano inoltre in un modo molto simile all’acciaio – senza le rotture fragili tipiche del vetro o della porcellana. Per maggiori informazioni puoi cliccare su “Prodotti”
