摘要： A boat propeller installation (1), in particular for motor boats, has a propeller driven at engine speed and provided with blades (5) having step bearings (7) that can pivot around threaded bolts (6) screwed into a propeller star wheel (8) mounted on the driving shaft (2). To make each propeller blade (5) turn, a hollow shaft (17) is provided that surrounds the driving shaft (2), as well as conical toothed wheels (14, 15) mounted on the hollow shaft and on the driving shaft, the teeth (12) of which engage the corresponding step bearing (7). To limit radial forces, the outer surface of each step bearing (7) is kept free. The step bearing (7) is radially held by a collar (9) of the threaded bolt (6).

摘要： Pour modifier l'angle d'incidence des pales d'helice (13), le mecanisme de reglage (27) manoeuvrable par un fluide de pression presente un piston annulaire (31) qui se meut dans un cylindre (28) et sur un axe (42). Des guides helicoidaux (43, 44) sont prevus entre le piston (31) et son axe (42) et/ou la paroi interieure du cylindre de pression (28). Lors du mouvement axial du piston (31), ces guides donnent a l'axe (42) un mouvement tournant. Sur la partie de l'axe (42) qui sort du cylindre (28) un pignon d'engrenage est fixe transmettant le mouvement du piston (31) a chacun des tourillons (16) des pales. Chaque tourillon (16) est doublement fixe au moyen de la pale et son extremite (20) dans un troncon de l'arbre d'entrainement.

摘要： A motor for driving a propeller is disclosed which has a drive shaft (10) which is coupleable to a propeller shaft (20) by bevel gears (12 and 14) so as to rotate the shaft (20) to in turn rotate propeller blades P of an outboard motor. The drive shaft (20) has an internal concentric shaft (30) which enables the adjustment of the pitch of the propeller blades P by mounting the propeller blades P for rotation about a pitch axis and coupling the mounting (72') via an integral bevel gear (104) to a bevel gear (102) on the shaft (30). A phase adjustment mechanism (40) is provided for rotating the shaft (30) relative to the shaft (20) to in turn rotate the propeller blades P around the pitch axis to change the pitch of the propeller blades P. The phase adjustment mechanism comprises ring gears (48 and 50), together with planet gears (48) in engagement with a gear on the shaft (30) and planet gears (46) in engagement with a gear (26) on the shaft (20). An anti-backlash mechanism for preventing movement with propeller blades P about the pitch axis due to backlash within the gears of the phase adjuster mechanism (40), includes a screw-threaded section (252) coupled with the shaft (30) and the yoke (270) on the section (252) for movement on the section (252) in the longitudinal direction of the shaft (30). Engagement between the screw-threaded section (252) and the yoke (270) forms a rigid coupling of the shaft (30) to the propeller blades P so that any backlash in the phase adjusting mechanism (40) is not transmitted through the coupling to the propeller blades P.

摘要： The invention relates to a marine propeller having adjustable propeller blades (5) attached to a hub (1, 2). The root-part (7) of each blade (5) is mounted in the hub (1, 2) for rotation about an axis that defines an angle with the axial direction of the propeller. A blade setting adjusting means (4, 5) is adapted for rotating all blades (5) in unison. According to the invention, the blade setting adjusting means comprises a blade setting adjuster ring (4) which includes locking means (20, 21) for co-action with locking means (22, 23) on the hub. The adjuster ring (4) can be moved axially between a locking position in which the adjuster ring is locked against rotation, and a release position in which the adjuster ring can be rotated relative to the hub (1, 2). The locking means (20, 21, 22, 23) define a plurality of distinct rotational positions of the adjuster ring (4). Movement transmission means (15, 17) transfer rotary movement of the adjuster ring (4) to respective blades (5).
