Abstract: A propeller shaft (1) is rotatable about a longitudinal axis (1A) and a hub (2) is mounted on the propeller shaft with propeller blades(4) projecting radially from the hub. Each propeller blade has a blade base (7) which includes a drum (9). A ring bearing (8) mounts the blade base to the hub such that the propeller blade is rotatable about a radial axis (4A). A cable or other flexible drive element (13) is looped around each drum and attached thereto by a bolt (14). Opposite ends (13a, 13b) of the cable (13) are attached to opposite ends of a pitch change rod (12) which extends transverse to the radial axis (4A). In one embodiment a control member (11) may extend within the propeller shaft (1) to reciprocably move the pitch change rods (12) and thereby change the pitch angle of the propeller blades (4). In another embodiment the pitch change rods (12) may be moved by a hydraulic cylinder within the propeller hub (2).

Abstract: The propeller has a hub (22, 23) rotatably carried on a drive shaft (2) with blades (3) projecting radially from the hub. Each of the blades includes a fixed-pitch portion which is fixed relative to the hub and a pitch-change flap (7) which is pivotable about a pitch-change axis extending along a trailing edge of each blade. At the root of each blade the flap has a pivot pin (16) which is inserted into the hub where the pin carries a pitch-change arm. The arms carry pitch-change pins (19) which are inserted into an axially movable control head (20). The control head may act against an adjustable compression spring (26) to provide automatic self-adapting pitch control. The control head may also be operated remotely by a cable, rod or hydraulic fluid passing through the propeller drive shaft.

The adjusting member (34) and the propeller blade (12) are operatively connected to one another such that a displacement, in the first dimension (L), of the adjusting member (34) results in a change in the pitch of the propeller blade (12). The adjusting member is adapted to be positioned in a first position in the first dimension (L) such that the propeller blade is in a feathering position. Said boss (14) comprises a rotational locking means (14a) adapted to, at least when said adjusting member (34) is in said first position, prevent said adjusting member (34) from being rotated around an axis of rotation (R) extending parallel to said first dimension (L).

Abstract: The invention is aimed to simplify conventional variable pitch propeller mechanism in a way to reduce number of moving parts, incorporate mechanical actuation instead of hydraulic, improve compactness and separate torsional shaftline loads from normal ones. Unlike the conventional system the patented one is based on inverted principle: rotation of propeller blades is not acomplished by linear movement of pins (19) but with movement of propeller hub (17) itself. Hub is provided with flange (30) firmly connected to propeller shaft (4) which is put in linear movement by means of electric motor and gears (8) (9) together with thrust bearing (5)(6) housing (7). Other components of shaftline (1)(27) are not effected due to sliding­only torque transmitting- connection (2). Basically, invention combines pitch actuating and thrust bearing functions embodied in single source produced, easy to install, compact and rigid unit. Favourable load distribution between components, improved watertight integrity, ease of maintenance of electro-mechanical drive and ability to withdraw the propeller shaft while propeller remains in its position are some of the major advantages of the invention. Instead of electro mechanic drive system can accept hydraulic drive in a way that thrust bearing housing (7) simulates piston of the cylinder (13) fed from hydraulic system which is identical to what is usually provided for conventional CPP system. Principle of fixed- non-rotating- propeller carrier (22) can be utilized for fiEed pitch propellers as well.

Abstract translation: 本发明旨在简化传统的可变螺距螺旋桨机构，以减少运动部件的数量，结合机械致动而不是液压，提高紧凑性和分离扭转轴线负载与正常运行部件的负载。 与传统系统不同，专利的是基于倒置的原理：螺旋桨叶片的旋转不是由销（19）的线性运动而是由螺旋桨毂（17）本身的运动所决定的。 轮毂设有牢固连接到传动轴（4）的凸缘（30），该传动轴（4）通过电动机和齿轮（8）（9）与推力轴承（5）（6）壳体（7）一起成直线运动。 轴线（1）（27）的其他部件不会因为滑动扭矩传递连接（2）而受到影响。 基本上，本发明组合了在单源生产，易于安装，紧凑和刚性单元中体现的桨距致动和推力轴承功能。 组件之间有利的负载分配，改善的水密完整性，易于维护机电驱动以及在螺旋桨保持在其位置时抽出传动轴的能力是本发明的一些主要优点。 代替电机驱动系统可以以推力轴承壳体（7）模拟从液压系统供给的气缸（13）的活塞的方式接受液压驱动，其与通常为常规CPP系统提供的活塞相同。 固定非旋转螺旋桨载体（22）的原理也可用于有偏转螺旋桨。

Abstract: A marine propulsion system comprising a push rod activated pins (170) which engage eccentric shaft (174) for unlocking a propeller base (190) so the base (190) can rotate around a transverse axis. The base (190) has an inclined suface (192) which engages with an inclined surface (159) defining an opening in the propeller’s hub therefore locking the propeller blade (34) in position. The inclined surfaces (159, 192) are disengaged by rotation of the eccentric shaft (174) thus the propeller blades (34) can be rotated to adjust the pitch and then the inclined surfaces (159, 192) re-engage to locking the propeller blade (34) in the pitch adjusted position.
