|20140301843||FEATHERING PROPELLER WITH ADJUSTABLE ABUTMENT - There is described an assembly having a plurality of screws, a propeller and a related method for adjusting the fluid dynamic pitch of the blades of the propeller. The propeller has at least one blade pivoted rotatably to a cylindrical propeller casing, a hub coupled to an engine and mounted coaxially inside the propeller casing, a kinematic mechanism coupled to the hub and/or to the propeller casing, and to the blade for adjusting the fluid dynamic pitch of the propeller. The hub is rotatable with respect to the cylindrical propeller casing, or vice versa, for at least one non-zero angular interval (α) of operation of the kinematic mechanism for adjusting the fluid dynamic pitch and is also integral with a contact surface movable between disengagement from and engagement with, direct or indirect, at least one relative abutment integral with the cylindrical propeller casing which defines a limit stop of the angular interval (α). The plurality of screws has at least two different screws and the propeller has a seat for complete installation of a screw selected from the plurality of screws, and the limit stop abutment has a region of screw selected from the plurality of screws installed in the seat provided in the propeller.||10-09-2014|
|20140291079||DEVICE FOR PREVENTING A SHAFT ROTATION - A device for preventing and/or stopping rotation of a shaft coupled to a motor, of the type having a first fixed element with respect to this shaft, and a moving element, and means to constrain the moving element to the shaft in such a manner as to rotate integrally with this shaft and at the same time be able to move between a position of friction contact with the fixed element, to allow stopping of the shaft, and a position of disengagement from this fixed element, to allow release of the shaft is disclosed. The device advantageously provides that the means to constrain the moving element to the shaft include a link for movement of the moving element along a direction having a radial component with respect to the shaft.||10-02-2014|
|20130202436||FEATHERING PROPELLER WITH BLADE DAMPENING AT FORWARD AND BACKWARD MOTION AND BLADES PITCH CONTROL DURING BACKWARD MOTION - Disclosed is a variable pitch propeller having a blade pivoted rotatably to a cylindrical propeller casing, a drive shaft, coupled to a propulsor and positioned coaxially inside the propeller casing, a kinematic mechanism coupled to the drive shaft, or to the propeller casing, and to the blade, for adjusting the rotary motion of the blade about its axis of pivoting to the propeller casing, and means for coupling in rotation the drive shaft to the propeller casing. The propeller provides a non-null angular range of relative rotation of the blade about its axis of pivoting, with respect to the propeller casing, or vice versa. The means for coupling in rotation the drive shaft to the cylindrical propeller casing include an elastic element interposed between the drive shaft and the cylindrical casing.||08-08-2013|
|20100260606||NAUTICAL VARIABLE-PITCH PROPELLER - Nautical variable-pitch propeller of the type comprising a hub driven by a drive shaft, an outer case externally constrained to the hub, and one or more blades, wherein each blade is constrained to the outer case freely to rotate around the (Y-Y) axis of an own shaft, the afore said outer case making each blade to rotate around the axis (X-X) of the hub, as well as a device for regulating the angular position of the blade around the (Y-Y) axis of its own shaft relatively to the hub. Advantageously, the regulating device comprises at least one moving member and means for transmitting movement from the moving member to the shaft of the blade, according to at least two different laws of motion transmission.||10-14-2010|
