Abstract

An arrangement for an adjustable propeller for vessels comprising a propeller (22) and a drive shaft (20) extending through the hull, at least two propeller blades (25) which are each mounted rotatably in a respective bearing seat, a propeller boss (17), and a supply duct (5) arranged in the said propeller boss (17) for supplying lubricant to the said seat, the cavity (21) in the propeller boss (17) being completely filled with lubricant which is under positive pressure, and the propeller boss (17) also comprising an outlet duct (6) for return flow of the said lubricant from the said bearing seat in the propeller boss (17) out through the propeller boss (17), the ducts (5), (6) being interconnected outside the boss (17) so that circulation of lubricant through the propeller boss (17) is brought about. A method for lubricating a propeller boss (17) in an arrangement for an adjustable propeller for vessels, lubricant being supplied to a cavity (21) in the propeller boss (17) through a duct (5), a cavity (21) being completely filled with lubricant, arrangement being made such that the lubricant is under positive pressure and is conveyed away from the propeller boss (17) through a duct (6), and in this way circulation of lubricant through the propeller boss (17) being brought about.
