The invention provides a stepless joint modulation variable pitch propeller which comprises a support assembly, a propeller hub, a variable pitch shaft and a plurality of blades, the propeller hub is arranged on the support assembly, a plurality of mounting holes are evenly formed in the periphery of the propeller hub, and a guide rail shaft is arranged in the center of the propeller hub; the variable-pitch shaft is arranged on the guide rail shaft in a sleeving manner, and a ring groove is formed in the outer wall of the variable-pitch shaft; a plurality of paddles are arranged in the mounting holes, eccentric pins are arranged at the roots of the paddles, and the eccentric pins are inserted into the annular grooves; when the eccentric pin moves in the annular groove, the paddle rotates in the axial direction, and the installation angle of the paddle is adjusted. Under the action of external force, the variable pitch shaft axially moves on the guide rail shaft, the eccentric pin is driven to rotate through the annular groove, and the paddles are driven to rotate in the axial direction. According to the invention, through the arrangement of the structure, all the blades can be driven to rotate synchronously, the adjustment consistency of the blade mounting angle is ensured, and meanwhile, the adjustment operation of the blade mounting angle is simpler and more convenient.

    本发明提供了一种无级联调变距螺旋桨,包括支架组件、桨毂、变距轴以及若干个桨叶,桨毂设置在所述支架组件,桨毂四周均匀设置有多个安装孔,桨毂中心设置有导轨轴;变距轴套设在所述导轨轴上,变距轴外壁上设置有环槽;若干个桨叶设置在安装孔中,桨叶的根部设置有偏心销,偏心销插入所述环槽中;偏心销在所述环槽中运动时,桨叶沿轴向转动,对桨叶的安装角进行调整;在外力作用下,所述变距轴在所述导轨轴上轴向移动,通过所述环槽驱动所述偏心销转动,带动所述桨叶沿轴向转动。在本发明中,通过设置上述结构,能够带动所有桨叶同步转动,保证了桨叶安装角调节的一致性,同时使桨叶安装角的调节操作更加简便。
