Abstract
Apparatus for adapting a propeller system including a propeller shaft (15, 16) and a propeller (7, 8) adapted to be mounted on the propeller shaft (15, 16). The propeller system includes a propeller (7, 8) connected in a rotationally fixed manner to a propeller shaft (15, 16), the propeller shaft (15, 16) having a portion provided with splines (19, 20) which cooperate with corresponding splines (25, 28) inside the hub (23, 26) of the propeller (7, 8) in order to obtain the rotationally fixed connection, where the splines (19, 20) on the propeller shaft (15, 16) and in the hub (23, 26) of the propeller (7, 8) are helical, with a predetermined oblique angle (α, β). The invention also relates to a propeller shaft (15, 16) and a propeller (7, 8) which are intended to be used in the propeller system.
