Verfahren zur Kühlung eines mit pulverisiertem Öl gemischten Untersetzungsgetriebes und Einrichtung zu dessen Anwendung.

摘要

The cooling method consists of sucking up inside the reduction gear previously filtered air which, when traversing the reduction gear, is mixed with the spray of lubricating oil so as to collect its calories and reject it outside after having purified it from the oil it contains. The equipment incorporates one or several air intakes provided with filters and an extraction fan driven by the reduction gear and provided with means for collecting and draining the oil. The application of this method is for reduction gears lubricated with sprayed oil and particularly for helicopter gearboxes.
