Title (EN) A MARINE PROPULSION ASSEMBLY UTILIZING A DUAL OPPOSED THREADED DRIVE SHAFT WITH TAPER
(FR) ENSEMBLE DE PROPULSION MARINE UTILISANT UN ARBRE DE TRANSMISSION À DOUBLE FILETAGE OPPOSÉ ET À SECTION CONIQUE
Abstract: front page image
(EN)A marine propulsion assembly (500) includes a propeller (502) having a threaded hub (505) whose threads are used for engaging with a drive shaft (501). The drive shaft includes both a first set of threads (507) and second set of threads such that the first set of threads (507) are used to engage with a keeper nut (514) and a second set of threads are used to engage within the propeller hub (505). The first set of threads (507) are configured to be opposite the direction of propeller rotation for preventing rotation of the keeper nut (514) while the second set of threads are configured opposite the direction of rotation of the propeller to prevent the propeller from loosening on the drive shaft. The drive shaft further includes a tapered section for providing a stop to the propeller when engaging with the second set of threads.
(FR)Un ensemble de propulsion marine (500) comprend une hélice (502) ayant un moyeu fileté (505) dont les filets servent à mettre en prise un arbre de transmission (501). L'arbre de transmission comprend un premier ensemble de filets (507) et un second ensemble de filets tels que le premier ensemble de filets (507) sert à mettre en prise un écrou de maintien (514) et que le second ensemble de filets est utilisé de manière à se mettre en prise dans le moyeu d'hélice (505). Le premier ensemble de filets (507) est agencé de manière à s'opposer à la direction de rotation de l'hélice afin d'empêcher une rotation de l'écrou de maintien (514). Le second ensemble de filets est agencé en opposition à la direction de rotation de l'hélice afin d'empêcher l'hélice de se desserrer sur l'arbre de transmission. L'arbre de transmission comprend en outre une section conique destinée à provoquer un arrêt de l'hélice lorsqu'elle est mise en prise avec le second ensemble de filets.
