摘要： A propeller assembly is disclosed, comprising propeller blades pivotably mounted on a propeller hub. A cam follower is disposed on each propeller blade. A cam is movable between a first position, a second position and a third position. Recesses formed in the cam have a first segment, a second segment and a third segment, oriented at first, second and third angles. The first segment is oriented at a first angle relative to the central axis. The cam followers engage the first segment of the recesses when the cam moves between first and second positions to vary the pitch of the propeller blades between a first pitch and a second pitch. The cam followers engage the second segment of the recesses when the cam moves between second and third positions to vary the pitch of the propeller blades between the second pitch and a third pitch.

The first and second propeller blades are pivotable with respect to the propeller hub about corresponding first and second pivot axes to vary a pitch of the first and second propeller blades. A support member has a first end at least partially disposed within the first propeller blade and a second end at least partially disposed within the second propeller blade. The first end has a first central longitudinal axis generally coaxial with the first pivot axis. The second end has a second central longitudinal axis generally coaxial with the second pivot axis. A gear case having a propeller and a marine outboard engine having a propeller are also disclosed.

摘要： A translational thrust system for a high speed rotary-wing aircraft includes a propeller system driven by a propeller gearbox, a hydraulic system, and a mechanical-hydraulic control system. The mechanical-hydraulic control system utilizes a hydraulic fluid which travels to and from a propeller dome via an oil transfer/position feedback tube which translates with a propeller pitch change piston. Translation of the oil transfer/position feedback tube and the propeller pitch change piston pitches the blades between high (coarse) and low (fine) pitch positions.

摘要： There is provided a self-actuating variable pitch marine propeller which incorporates two or more blades, each independently rotatable, relative to the propeller hub, between a first lower and a second higher pitch. The blades are preferably mechanically linked by coordinating means and are caused to move preferably by a combination of centrifugal force effect resulting from inertial mass means and the hydrodynamic forces acting upon the blade hydrodynamic surface. The rotation of the blades relative to the propeller hub is limited primarily as to speed of rotation by restricted viscous fluid flow damping means operably connected to the blades. In one preferred embodiment, the viscous flow means further acts as an initial restraint against all motion by closing off the viscous flow orifice until a certain minimum propeller rotational speed is achieved.
摘要翻译：提供了一种自致动的变桨距船用螺旋桨，其包括两个或更多个叶片，每个叶片可相对于螺旋桨轮毂独立地在第一下部和第二较高间距之间旋转。叶片优选地通过协调装置机械连接，并且优选地通过由惯性质量装置产生的离心力作用和作用在叶片流体动力表面上的流体动力的组合移动。叶片相对于螺旋桨轮毂的旋转主要受限于可操作地连接到叶片的粘性流体阻流装置的旋转速度的限制。在一个优选实施例中，粘性流动装置还通过关闭粘性流动孔口作为抵抗所有运动的初始约束，直到达到某一最小推进器转速为止。

摘要： A controllable pitch propeller assembly has an inner housing attached to a main drive shaft, the housing having rails on the outer surface thereof. Modules carrying the propeller blades are positively mounted on the rails, each module having a housing receiving a hub cylinder and bushings axially aligned at opposite sides thereof. Each pair of bushings receives an adjusting piston having an adjusting pin which engages a groove forming a control path in a propeller hub. Each blade is adjusted by a control lever which adjusts each adjusting piston through a mechanical linkage including an adjusting sleeve and a thrust bearing and flange. The hub is provided with open spaces formed between the inner and outer housings to create hub through exhaust ducts.

摘要： A combination motor boat propulsion and steering control system is shown which is particularly adapted to planing hull, high speed boats. The invented combination will eliminate the need for a rudder in such craft by providing dual variable pitch propellers, differentially pitch controlled for steering, and provides for water contact only up to the hubs of counterrotating propellers, thereby minimizing drag. Forward-reverse control and optimized speed control (while maintaining high power transfer efficiency) are effected by superimposed separate control of propeller pitches together in the same sense.
