Registration La maggior parte dei cuscinetti volventi è costituita da anelli muniti di piste volventi (anello interno ed anello esterno), dai corpi volventi (sfere o rulli) e da una gabbia di trattenuta dei corpi volventi. La gabbia separa i corpi volventi ad un intervallo regolare, tenendoli in posizione tra la pista interna e quella esterna permettendo la libera rotazione.L’anello situato all’interno che poggia sull’asse è chiamato “anello interno”, mentre quello situato all’esterno è chiamato “anello esterno” e poggia sull’allestimento. I corpi volventi rotolano su di una superficie di contatto chiamata “superficie pista volvente”che va a supportare il carico posto sul cuscinetto.Generalmente, i cuscinetti con angolo di contatto minore di 45° hanno capacità di carico radiale superiore, e sono classificati come cuscinetti radiali. Invece, quelli con angolo di contatto maggiore di 45° hanno una maggiore capacità di carico assiale, e sono classificati come cuscinetti assiali. Esistono inoltre cuscinetti combinati, che associano in se le caratteristiche dei cuscinetti radiali ed assiali.Tutti i cuscinetti volventi presentano i seguenti vantaggi: (1) The friction coefficient of first detachment has a lower value than the dynamic one, even if not very relevant; (2) They comply with an international standardization with characteristics of interchangeability and availability; (3) Lubrication is simple and very limited; (4) In general, a bearing can support both a radial load and an axial thrust at the same time; (5) They can be used in applications involving both high and low temperatures; (6) Bearing stiffness can be increased by means of preload. The rolling elements have two general configurations: balls and rollers. The balls have a geometric point contact on the surfaces of the inner and outer ring races, unlike the rollers with a contact consisting of a line. A roller bearing compared to a ball bearing having the same overall dimensions has a greater load capacity. For this reason, roller bearings are more suitable for applications with high loads and a longer life than the shocks received.
