Embodiment Construction

[0050] figure 1 A prior art arrangement for supporting a propeller shaft of a marine vessel is schematically depicted. A propeller shaft 10 with a propeller 12 attached to its stern end is supported to a stern tube 18 by means of a bow bearing 14 and a stern bearing 16 . The stern tube 18 is fastened at its bow end to a bulkhead 20 and at its stern end to a bracket 22 attached to a stern frame 24 . At its bow end, the stern tube 18 is provided with an inlet 26 for water SW, and a bow seal 28 preventing water from entering the interior of the hull. The bow seal 28 is arranged in a compartment in the hull that is different from the compartment in which the stern tube 18 is located. Water that has been pumped to the bow water lubricated bearing 14 through the inlet 26 passes through the bow bearing 14 and between the stern tube 18 and the propeller shaft 10 to the stern water lubricated bearing 16 , passes through the bearing 16 , and passes through the stern tube 18 The outle...

Abstract

The present invention relates to an arrangement for supporting a propeller shaft of a marine vessel and a method of servicing such. The arrangement and the method of the present invention are mainly aiming at a construction, which allows the servicing, maintenance and condition monitoring primarily from inside the marine vessel.

Description

technical field [0001] The present invention relates to an arrangement for supporting a propeller shaft of a marine vessel and a method of servicing the arrangement. The apparatus and method of the present invention are primarily directed to a structure that allows servicing, maintenance and condition monitoring to be performed primarily from within the marine vessel. Background technique [0002] Marine vessels are propelled with the aid of one or more propellers, usually located at the stern of the marine vessel. The propellers and rudders are the only parts of the marine vessel's machinery that extend outside the marine vessel's hull. The propeller is connected to the power source by means of a propeller shaft. Typically, a stern tube is used to support the shaft. The stern tube is a hollow tubular structure at the stern (stern tank) of a marine vessel, through which the propeller shaft passes and connects the power source and the propeller. [0003] The stern tube is...
