Abstract

The invention provides a blade swing mechanism. The blade swing mechanism comprises at least one steering machine, an adjusting rod connected with the steering machine through a driving rod and a driven rod, and connection rod mechanisms used for connecting the adjusting rod and a corresponding blade. One end of the driving rod and one end of the driven rod are arranged together in a rotating mode, the other end of the driving end is fixedly connected to a power output shaft of the steering machine, and the other end of the driven rod and the upper end of the adjusting rod are fixedly arranged together; the middle of the adjusting rod is sleeved with a first knuckle bearing fixed in the axial direction, and the connection rod mechanisms and the lower end of the adjusting rod are connected together. The invention further provides a marine cycloidal propeller. The marine cycloidal propeller comprises a fixed base provided with at least one blade, a motor installed on the fixed base, a transmission mechanism used for transmitting motor power and driving the blades to revolve, and the blade swing mechanism. Each blade corresponds to one connection rod mechanism, and the axis line of the first knuckle bearing and the central line of revolution motion of the blades are coincident. The blade swing mechanism is controlled by the steering machine, so real-time performance is good; the cycloidal propeller utilizing the blade swing mechanism is high in control accuracy, good in real-time performance and high in flexibility.

Description

technical field [0001] The invention relates to power equipment installed on ships, in particular to a blade swing mechanism used on the ship power equipment, and also to a cycloidal propeller for ships including the blade swing mechanism. Background technique [0002] The cycloid thruster is a propulsion device with a vertically installed rotary shaft, which can quickly change the size and direction of thrust at all angles, and realize the lateral movement, slewing and other movements of the ship. Compared with the propeller propeller, the cycloid propeller has the advantages of large hydraulic cross-sectional area, small water rotation loss, convenient operation, and fast response, which can greatly improve the flexibility of the ship. [0003] At present, the control device of the cycloid propeller at home and abroad generally adopts a hydraulic system, through which the direction of the blades on the propeller is controlled to complete the self-rotation motion of the...
