A Modular Cycloidal Propeller Using a Gear Synchronous Kite Mechanism

Abstract

The invention discloses a modular cycloidal propeller adopting a gear synchronous kite mechanism, which comprises a gear synchronous kite mechanism, an adjusting mechanism and a driving mechanism. One end of each kite-shaped mechanism is hinged on the control shaft, and the other end is connected to the rotation shaft of the blade through a pair of gears. The synchronous movement of the gear meshing makes the blade revolve around the base while always rotating perpendicular to the blade's rotation in the direction of the blade chord. The regular rotation of the line connecting the shaft and the control shaft; the revolution motion of all blades realized by the driving mechanism, and the rotation motion of each blade realized by the kite-shaped mechanism, the two work together to generate a cycloidal propulsion; further change through the adjustment mechanism Control the radial and circumferential plane positions of the shaft, and change the thrust magnitude and direction of the propeller. The invention can make the blades move precisely according to the cycloid law, improve the propulsion performance and has the feature of modularization, and can be conveniently installed on the underwater carrier.

AI Technical Summary

Problems solved by technology

However, the structural design of the cycloidal propeller is not mature at present. The common ones are cam type, gear type, six-link type, crank slider type, steering gear type, stepping motor type, etc., among which the cam type and gear type cannot be adjusted. The position of the control point seriously affects the maneuverability of the cycloidal propeller. The six-link structure has strict requirements on the length of each link. It is necessary to accurately calculate the length of each link. The crank-slider structure cannot be adjusted. The size of the eccentricity, the steering gear structure is difficult to achieve precise control of each blade in terms of control, the stepper motor type needs to write a special blade control algorithm according to the swing law of the blade, and when the number of blades increases, the stepping of the control needs to be controlled. The number of motors will also increase

These schemes are difficult to give full play to the superior performance of the cycloid propeller
