Arrangement for propeller of rudder propeller of watercraft, comprises propeller with section extending into shaft opening, in which groove formed radially outward is placed to form winding protection between shaft opening and propeller

摘要

#CMT# #/CMT# The arrangement comprises a lower housing part (11) provided with a shaft opening (12), from which a propeller shaft (13) projects and on which a propeller (10) is arranged. The propeller has a section extending into the shaft opening, in which a groove formed radially outward is placed to form a winding protection between the shaft opening and the propeller. The shaft opening completely overlaps a groove till a residual gap. The section has a collar, which forms a circumferential sealing gap against an inner side of the shaft opening. #CMT#USE : #/CMT# Arrangement for a propeller of a rudder propeller (all claimed) of a watercraft. #CMT#ADVANTAGE : #/CMT# The propeller has a section extending into the shaft opening, in which a groove formed radially outward is placed to form a winding protection between the shaft opening and the propeller, where the section has a collar, which forms a circumferential sealing gap against an inner side of the shaft opening, and thus prevents damage of the housing part of the watercraft by providing enhanced winding protection between the shaft opening and the propeller, and enables efficient rotation of the propeller. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side perspective view of a rudder propeller. 10 : Propeller 11 : Lower housing part 12 : Shaft opening 13 : Propeller shaft 100 : Rudder propeller.
