Question
Buongiorno, volevo sapere la misura dell’albero motore e la misura dell’albero lento. Grazie
Answer

Buongiorno,

Grazie per l’immagine tecnica inviata. Ecco le misure rilevabili dal disegno:

? Albero motore (lato flangia – foro entrata)

  • Diametro foro centraggio: Ø60 h8

  • Distanza tra fori di fissaggio: Ø87 mm (diametro esterno), Ø75 mm (centraggio)

  • Albero motore (foro d’accoppiamento – vista in basso a sinistra):

    • ØD = 14 mm

    • b = 5 mm (chiavetta)

    • t = 4 mm (profondità cava)

? Albero lento (uscita riduttore – albero maschio)

  • Diametro albero uscita: ØD1 = 25 mm

  • Lunghezza utile (parte sporgente): 26 mm x 2 + 26 mm (corpo centrale) = 78 mm

  • Cava chiavetta:

    • b1 = 8 mm

    • t1 = 3 mm

Se hai bisogno di confermare la compatibilità con un motore specifico o con un accoppiamento particolare, posso aiutarti a verificarlo.
