    Abstract: Presented is an arrangement and a method for sealing a propeller shaft (1) of a marine vessel. The arrangement comprises a propeller shaft (1) rotatable supported with at least one bearing (2), a bearing arrangement (3), a first lubrication arrangement (4) comprising a first lubricant circulation line (5) for conducting first lubricant to and from said bearing arrangement (3), a shaft seal arrangement (7) for sealing the propeller shaft (1) against sea water, and a second lubrication arrangement (8) comprising a second lubricant circulation line (9) for conducting second lubricant to and from said shaft seal arrangement (7). A first heat exchanger (11) is in thermal contact with the first lubricant circulation line (5) and in thermal contact with the second lubricant circulation line (9).

    Abstract: Presented is an arrangement and a method for sealing a propeller shaft (1) of a marine vessel. The arrangement comprising a shaft seal arrangement (2) and a lubrication arrangement (3) comprising a lubricant circulation line (4) for conducting lubricant to and from said shaft seal arrangement (2) and a lubricant circulator (5). The lubricant circulation line (4) comprises a connection line (7) that is connected in fluid connection with the lubricant circulation line (4) downstream of the lubricant circulator (5) and upstream of the shaft seal arrangement (2), and that is connected in fluid connection with a second part of the lubricant circulation line (4) so as to selectively conduct a part of the flow of lubricant past the shaft seal arrangement (2). At least one hydraulically operated pressure relief means (8) is configured to control the flow of lubricant in the connection line (7).

    Abstract: The propulsion unit comprises a housing (20) supported on a vessel. A propeller shaft (30) extends in the housing. The propeller shaft is rotatably supported with a first bearing (100) and a second bearing. A propeller is attached to at least one end of the propeller shaft. The first bearing (100) comprises a first radial bearing (110) and a first thrust bearing (120). The first radial bearing is a sliding bearing positioned axially inside the first thrust bearing. The first bearing is positioned at the first end of the housing and the second bearing being positioned at the second end of the housing or vice a versa.

    Abstract: A connection assembly for a fuse base connection terminal (2) comprises a base (1) and a connection terminal (2) arranged on the base (1). A connection hole (21) is arranged on the connection terminal (2). The connection assembly also comprises a support piece (3) plugged into the connection terminal (2). The support piece (3) comprises an accommodation groove (31) used for accommodating a nut (4) or a bolt (5). A side surface of the accommodation groove (31) is provided with an opening (32). A bottom of the accommodation groove (31) is provided with a through hole (37). A position corresponding to the support piece (3) on the base (1) is provided with a bolt mounting hole (11). The bolt mounting hole (11), the connection hole (21) and the through hole (37) are on the same axis. Because the support piece (3) that can be plugged into the connection terminal (2) is arranged and the nut (4) or the bolt (5) can be put into the support piece (3), a user is free to choose to put the nut (4) or the bolt (5) into the support piece (3) to connect of the connection terminal (2) to a cable.
