General catalogue gearboxes with bevel and/or helical gears-12

Ogni volta che si compie un lavoro (accelerare, frenare o mettere in rotazione delle masse, vincere attriti, effettuare sollevamenti, far traslare un carico su un piano orizzontale o inclinato ecc.) si ha sempre un assorbimento di potenza. In alcuni casi, determinare in modo sufficientemente approssimato la potenza necessaria è molto semplice, in altre applicazioni (soprattutto coclee, agitatori, mescolatori, macchine automatiche ecc.) l’approssimazione è più difficile; pertanto in questi ultimi casi è consigliabile riferirsi ad applicazioni similari già esistenti e funzionanti, al fine di effettuare...
