A propeller assembly includes a hub 1 secured to a shaft 2 and a plurality of radially-extending propeller blades 3 each having a mounting flange 4 seated on the hub. The blades are held to the hub by first and second axially-spaced clamping rings 9 and 10 that may have axially-extending collars 11 and 12 which co-operate with inclined shoulders on the mounting flanges to position and hold the flanges to the hub. The longitudinal edges of the mounting flanges (18 and 19, Fig 3) may abut each other. The first clamping ring 9 may be located relative to the hub by an annular abutment 8 and the second ring 10 may be urged axially by a propeller nut 24, which may include a plurality of individually-adjustable thrust elements 25. |
