A non-contact type online continuously-adjustable propeller pitch propeller comprises a propeller hub and a plurality of propeller blades, each propeller blade comprises a blade and a propeller root, a motor is arranged on the propeller hub, the end of each propeller root extends into the propeller hub, a transmission mechanism is arranged between the end of each propeller root and the corresponding motor, and a bearing is arranged between each propeller root and the corresponding propeller hub; the propeller further comprises a wireless signal receiving unit, the wireless signal receiving unit is connected with the motor controller, the motor controller controls the motor to act according to received wireless signals, and the motor drives the propeller root to rotate through the transmission mechanism to achieve adjustment of the propeller pitch angle. According to the propeller, electric energy is supplied in a brushless transformer mode, non-contact power supply is achieved, the power supply unit of the propeller pitch adjusting device on the propeller hub is greatly simplified, and the power supply reliability is improved. A harmonic reducer with a power-off brake and a reduction ratio of 80: 1 and a small base number motor driver all-in-one machine are adopted, three-angle torques are uniformly output through a taper gear to adjust the propeller pitch, and blades are automatically locked after the propeller pitch is adjusted.
一种无接触式在线连续可调桨距的螺旋桨,括桨毂和若干桨叶,桨叶包括叶片和桨根,桨毂上具有有电机,桨根的端部伸入桨毂内,桨根端部与电机之间具有传动机构,桨根与桨毂之间具有轴承;还包括无线信号接收单元,无线信号接收单元与电机控制器相连,电机控制器根据接收到的无线信号控制电机动作,电机通过动传动机构带动桨根转动实现桨距角的调节。本发明的螺旋桨,采用无刷变压器方式供给电能,实现无接触式供电,大大简化了桨毂上桨距调节装置的供电单元,并提高了供电可靠性。采用带失电制动器的80:1减速比的谐波减速器加小机座号电机驱动器一体机,通过锥度齿轮均匀输出三个角度的转矩调节桨距,并在调节桨距后自动锁紧桨叶。
