Abstract

Inventia se refera la un dispozitiv pentru schimbarea pasului elicelor cu pale reglabile de la navele de transport, putând fi amplasat pe linia arborilor pentru a simplifica constructia si a reduce gabaritul instalatiei de reglare a pasului elicei. Actiunea de modificare a pasului elicei se realizeaza pe cale hidraulica cu ajutorul unor pompe alcatuite din niste roti dintate, actionate direct de linia de arbori, iar pentru cuplarea acestor pompe se utilizeaza niste discuri împreuna cu niste resorturi care sub actiunea unor pistoane actioneaza roata dintata motoare cu niste pinioane pentru ca fluidul sub presiune sa fie dirijat spre cilindrul de actionare a palelor.The invention relates to a device for changing the pitch of the adjustable blades of the transport vessels and can be placed on the tree line to simplify the construction and reduce the gauge of the propeller pitch adjustment device. The action of changing the pitch of the propeller is done hydraulically by means of pumps made of gears driven directly by the shaft line, and for the coupling of these pumps, some discs are used together with some springs which under the action of some pistons drive the toothed wheel with some sprockets for the pressurized fluid to be directed to the blade drive cylinder.
