Sliding lever type cycloidal propeller

Abstract

The invention relates to a sliding lever type cycloidal propeller. The sliding lever type cycloidal propeller consists of a driving mechanism and an attack angle control mechanism. A gear of a drivingmotor of the driving mechanism is engaged with a gear of a propeller blade driving disc so that the propeller blade driving disc drives propeller blades to rotate to provide power for the cycloidal propeller. Each propeller blade shaft can freely rotate within a hole position and is connected with an attack angle control hub through a sliding rod to control the attack angles of each propeller blade in different positions. A control shaft in the attack angle control mechanism changes a phase angle of a propeller blade attack angle changing period according to a rotating angle of a control discso as to change thrust directions of the propeller blades. The sliding lever type cycloidal propeller has the beneficial effects that separate control of a rotation speed and a phase angle of the cycloidal propeller is realized, the moving rules of different propeller blades of the cycloidal propeller are completely as same as each other, and the integral thrust is stable; the sliding lever typecycloidal propeller has the characteristics of less special members, reasonable layout, simple and reliable structure and convenient maintenance; and the sliding lever type cycloidal propeller has thecharacteristics of no friction pair and less transmission links in the working process and small mechanical loss.

Description

technical field [0001] The invention belongs to the field of power devices for surface ships and underwater vehicles, and relates to a slider-type cycloid propeller. Background technique [0002] Cycloidal propellers are also called straight-wing propellers and flat-rotating propellers. It is a disc propeller with vertical blades parallel to each other and to the axis of rotation of the disc. During the revolution around the disk axis, the blades will also periodically swing around their own axis, that is, different angles of attack will be at different positions, so that the blades can generate thrust in the same direction at different positions. By adjusting the size of the maximum angle of attack, the magnitude of the thrust can be changed; by adjusting the phase angle of the periodic change of the angle of attack, the direction of the thrust can be changed. Therefore, the cycloidal propeller has the characteristics of flexible and adjustable thrust vector, which can gi...
