摘要:
The present disclosure relates to a separation plate (140) configured to be disposed between an azimuth unit (104) and an upper gear unit (102) of an azimuth thruster (100) such that a first lubricant compartment (160) disposed inside the azimuth unit (104) is at least partially separated from a second lubricant compartment (162) disposed inside the upper gear unit (102). The separation plate (140) comprises a cylindrical body (164) with a central axis (166). The separation plate (140) further comprises a hole (142) formed in the cylindrical body (164) and configured to fluidly connect the first lubricant compartment (160) to the second lubricant compartment (162). The separation plate (140) further comprises a hollow space (170) formed in the cylindrical body (164) and open to the first lubricant compartment (160), the hollow space (170) including a defined minimal accommodation volume configured to accommodate a volume of lubricant such that a lubricant level (402) in the second lubricant compartment (162) is below an upper gear crown wheel (116) of the upper gear unit (102) during operation of the azimuth thruster (100).

The present disclosure relates to a sealing assembly (19) for a thruster support pipe (20) of a retractable thruster assembly (10) of a marine ship or vessel. The sealing assembly (19) for sealing between the movable thruster support pipe (20) and a foundation plate (22) with an opening (50) may comprise a main body (80) with a first inner sealing ring (90), a bearing (84), and an outer sealing ring (104). The main body (80) may be allowed to radial move with the thruster support pipe (20) within the opening (50). Thus, excessive radial forces particularly on the sealing assembly (19) may be reduced.

A variable pitch propeller (1) and a propeller blade flange (9) for a marine vessel is provided. The variable pitch propeller (1) comprises a propeller hub (3), a propeller blade flange (9) for a propeller blade (7) and a sealing arrangement (19). The sealing arrangement (19) comprises a first seal (35) a second seal (37) arranged to substantially prevent matter from passing between the propeller hub (3) and the propeller blade flange (9).
摘要:
An azimuth thruster (100) for a marine vessel is disclosed. The azimuth thruster (100) comprises an azimuth unit (104) for slewing the azimuth thruster (100). The azimuth thruster (100) further comprises an adjustable lubricant level measuring device (170) arranged to measure a lubricant level at the azimuth unit (104), the lubricant level measuring device (170) being adjustable to set a lubricant level measuring location of the lubricant level measuring device (170). The adjustable lubricant level measuring device (170) allows setting the lubricant level measuring location based on an installation orientation of the azimuth thruster (100).
摘要:
A power system for a marine vessel comprises an engine and a controllable pitch thruster (14) drivably coupled to the engine. A speed of the controllable pitch thruster various with a speed of the engine. A control unit (16) receives a thrust command value indicating a thrust required from controllable pitch thruster (14). The control unit (16) determines a current speed of the controllable pitch thruster (14) and calculates a pitch of the controllable pitch thruster (14) that produces thrust in accordance with the thrust command value at the current speed of the controllable pitch thruster. The power system allows for operating the engine at variable speeds to allow for a reduction of the engine speed under partial load conditions.

摘要:
A leakage detection system for an azimuth thruster (100) comprises an azimuth seal (12) defining a plurality of spaces between the same and a sealing surface (20) of a rotatable inner part (16) of the azimuth thruster (100). Via the respective spaces, a flow of compressed air can be supplied to an inner space provided between a propeller shaft seal (24) and a propeller shaft (134) of a lower gear unit (106) of the azimuth thruster (100). In this manner, a leakage of oil and/or water into the inner space (26) of the propeller shaft seal can be sucked from the inner space (26) via the azimuth seal (12) and detected by a detection unit (38).
