Abstract

The invention discloses a straight-wing cycloidal propeller with a stepping motor as a control mechanism. A main motor mounting bracket is arranged on a mounting base; a main drive motor is arranged on the main motor mounting bracket; the main drive motor is connected with a main shaft through a connecting shaft; the connecting shaft is sleeved with a conducting ring; the main shaft is connected with a revolving box below the mounting base; a first blade control motor and a second blade control motor are arranged inside the revolving box; the first blade control motor is connected with a first blade; and the second blade control motor is connected with a second blade. The invention solves the problems that common straight-wing cycloidal propellers are complicated in control mechanism, short in service life, slow in dynamic response, etc., greatly improves the propelling efficiency of the straight-wing cycloidal propeller, and is favorable for popularizing and applying the straight-wing cycloidal propeller with excellent control performance.

Description

technical field [0001] The invention relates to ship power equipment, in particular to a straight-wing cycloid propeller with a stepping motor as a control mechanism. Background technique [0002] At present, the generally used straight-wing cycloid propellers all use connecting rods and cam mechanisms to control the rotation of the blades. At the same time, the external control mechanism, such as two hydraulic cylinders perpendicular to each other, changes the rotation law of the blade through the lever, and can quickly change the direction and magnitude of the thrust within the range of 360°. The control mechanism using a mechanical structure as the propeller has shortcomings such as complex structure and severe wear, and is limited by the movement of the mechanism itself. its propulsion performance. [0003] Stepper motor is an actuator that converts electrical pulses into angular displacement, which can realize precise control of the rotation angle, fast dynamic respon...
