摘要： A circulatory device comprising a large diameter fan having reinforced fan blades with a tapered airfoil shape is disclosed. The fan blades may be formed using an extrusion method of fabrication, wherein each fan blade may comprise a reinforced trailing edge with a downwardly extending flange. The benefit of forming each fan blade with a reinforced trailing edge of the present invention results in improved structural characteristics such that the trailing edge of each fan blade may be fabricated longer so as to improve aerodynamic performance. Also, the reinforced trailing edge resists tearing that my occur during extrusion by adding the bent flanged region to at least one distal end of the trailing edge. For example, the bent portion of the trailing edge tends to rigidly orient the extruded material in a stabilized position more readily during formation. Also, the bent portion provides added strength by providing supporting forces in two dimensions that relatively parallel and perpendicular to its length so as to neutralize the adverse effects of pressure forces acting on the trailing edge of the fan blade during extrusion.

摘要： A marine propeller drive (1) for boats, including a gearbox (10) for a motor transmission and an associated impelling propeller (12), where said propeller (12) is provided with a propeller hub (14), the main peripheral cross-section dimension (A) of which is less than the main peripheral cross-section dimension (B) of the gearbox (10) and where a transition cone (18) is located between the gearbox (10) and the propeller hub (14). The transition cone (18) has: - a front end (20) located in connection with the gearbox (10), where said front end (20) has an initial peripheral cross-section dimension (C) essentially corresponding to the main peripheral cross-section dimension (B) of the gearbox (10); - a rear end (22) located in connection with the propeller hub (14), where said rear end (22) has a connecting peripheral cross-section dimension (D) essentially corresponding to the main peripheral cross-section dimension (A) of the propeller hub (14). The invention is distinguished in particular by the fact that the transition cone (18) includes a bulb-shaped shoulder part (24) located between said front end (20) and rear end (22), the largest peripheral cross-section dimension (E) of which exceeds the initial peripheral cross-section dimension (C) of the transition cone (18).

摘要： A variable-pitch propeller, especially for a sport board, has angularly displaceable blade support plates (1) which can be rotated about respective radial axes (2). The plates (1) are provided with radially inwardly directed claws (4) which engage in circumferential grooves (11) of bases (7) of the blades (8). The latter can have radial projections (12) reaching beneath the claws (4). The resulting bayonet connection simplifies mounting and dismounting of the propeller blades (8) even under water.

摘要： The invention concerns an impeller or a propeller for a rotary machine such as a pump, a turbine or a propulsion unit.
The impeller comprises a hub (1) and an intermediate part put together by a number of identical hub sections (3) with mounted vanes (4). The partition between two hub sections (3) follows a curve which is substantially axially directed.

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).
