Un sistema misto bagno d’olio-sbattimento garantisce di regola la lubrificazione dei riduttori. Per alcune posizioni di montaggio, generalmente caratterizzate da uno dei due assi verticali, opportune precauzioni vengono adottate al fine di garantire una adeguata lubrificazione anche agli organi più sfavoriti. Lubrication of gear units is usually provided through a combination of oil immersion and oil-splash patterns. For some mounting positions, typically those featuring a vertical shaft, provisions are made to guarantee lubrication of even the least favourably located drive components. Normalerweise...
