1.3 - LUBRIFICAZIONE Gli organi interni dei riduttori HDPE sono lubrificati con un sistema misto di immer-sione e sbattimento dell’olio. Per velocita di comando inferiori a 500 min-1 o supe-riori a 1750 min-1, consultare preventiva-mente il Servizio Tecnico di Bonfiglioli. La lubrificazione del supporto estrusore e comune con quella della cassa del ridut-tore. I riduttori sono forniti privi di lubrifi-cante e sara cura del Cliente immettere, prima della messa in opera, la quantita di olio appropriata. Le quantita di lubrificante riportate in tabella sono indicative. Per il corretto riempimento...

Per il riduttore selezionato verificare la disponibilità della relativa flangia di accoppiamento nella sezione 3.5. La normalizzazione tipica dei motori elettrici può portare a selezionare un motore caratterizzato da potenza di targa superiore, anche considerevolmente, alla potenza nominale Pn1 del riduttore che si è dimensionato. Verificare che in nessuna condizione del ciclo di lavoro la maggiore potenza erogabile dal motore elettrico sia effettivamente sviluppata. In presenza di dati di calcolo incerti, o di dubbi sull’effettivo diagramma di carico dell’applicazione è consigliabile installare...

2.2.4 - CARICHI AGENTI SUGLI ALBERI Carichi radiali e assiali albero veloce Overhung and thrust loads on input shaft When checking the overhung load capacity refer to scheme shown at paragraph 2.2.3. Calculate the admissible overhung load Rx that is relevant to the distance the force applies from shaft midpoint and compare this with the force Rc that acts onto the shaft. Multiply the nominal radial load Rn1, as listed in the technical data section, for the load location factor K1 to get the permissible overhung load Rx1 for the output shaft. Rated overhung loads Rn are calculated for the most...
