Slide-rod cycloidal paddle propeller with adjustable maximum attack angle

Abstract

The invention relates to a slide-rod cycloidal paddle propeller with an adjustable maximum attack angle. The slide-rod cycloidal paddle propeller with the adjustable maximum attack angle is composed of a drive mechanism and an attack angle control mechanism. A gear of a drive motor of the drive mechanism is engaged with a gear of a paddle drive disc, the paddle drive disc is enabled to drive paddles to rotate, and power is provided for the cycloidal paddle propeller. Each paddle shaft is capable of freely rotating in a hole position, connected together with an attack angle control hinge through a slide rod, and used for controlling the attack angles of the paddles at different positions. A control shaft in the attack angle control mechanism changes a phase angle of an attack angle change period of each paddle by controlling a rotation angle of a control disc, and then changes a thrust direction of the paddle. A distance between the axis of the control disc and the control shaft is adjusted by an axial stepper motor, and the maximum attack angle adjustment is realized. The slide-rod cycloidal paddle propeller with the adjustable maximum attack angle has the following beneficial effects: the slide-rod cycloidal paddle propeller with the adjustable maximum attack angle is provided with few specially-shaped members and reasonable in layout, and has the characteristics of being simple and reliable in structure, and convenient to maintain; and the slide-rod cycloidal paddle propeller with the adjustable maximum attack angle is not provided with a friction pair in a working process, has few transmission links, and has the characteristic of being low in 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 with adjustable maximum angle of attack. 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 an...
