Funzionamento tipico del V-ring

C

Il corpo o spalla del v-ring, garantisce un'

ottima adesione all' albero rotante.

L

La struttura conica del labbro aderisce alla

superficie assiale adattandosi anche ad

eventuali inclinazioni dell' albero.

G

La giunzione tra il labbro e la spalla avviene

tramite un prolungamento che funge da

molla

L' anello V-ring viene calzato sull' albero con il labbro di tenuta aderente alla superficie assiale. L' anello V-ring

ruota assieme all'albero , il labbro viceversa striscia sulla parte fissa dove garantirà una tenuta nei due versi

dall'interno verso l'esterno e che inquinanti non filtrino all'interno.

Tipo VS Tipo VB

Tipo VL

Esempio di tenute a labirinto Montaggio tipo VB con fascetta

Profilo più comunemente usato per alberi da

3mm a 1200mm. Diametri maggiori sono

realizzabili vulcanizzati.

Profilo del labbro uguale al tipo VA. Differisce

dal tipo VA per un' estensione del corpo o spalla

aumentando così la forza dell'accoppiamento

tra anello e albero anche del 50% . Questa

tipologia si consiglia in presenza di alte velocità

e lunghe esposizioni a contaminanti esterni. La

gamma dei diametri va da 5mm a 200mm

Profilo caratterizzato per un ridotto ingombro

indicato per applicazioni di tenuta a labirinto. La

gamma dei diametri va da 120mm a 600mm

Profilo molto rigido per applicazioni molto

gravose. La gamma dei diametri va da 300mm

a 1200mm

Profilo con la stessa geometria e rigidità del VE.

Viene utilizzato per impieghi gravosi e su

diametri oltre i 300mm fino ai 2000mm. Nella

parte esterna della spalla viene ricavata una

cava per installare una fascetta metallica per un

migliore montaggio radiale. Il tipo VB viene

realizzato da estruso vulcanizzato.

Rugosità superfici

La tabella sottostante elenca i valori di rugosità (finitura superficiale) della superficie di scorrimento

dove il labbro del V-ring scorre. I valori devono essere rispettati per un ottimale funzionamento anche

in presenza di inclinazione dell' albero.

Inclinazioni dell' albero

A differenza dgli altri anelli di tenuta V-ring può mantenere un ottimo grado di tenuta anche

quando l' albero rotante presenta un' inclinazione rispetto all' asse di rotazione.

Si consiglia di non superare mai 1° di inclinazione.
