The invention discloses an adjustable pitch ratio propeller, and relates to the field of propellers, the adjustable pitch ratio propeller comprises three blades, a plurality of bolts and a variable pitch assembly, the variable pitch assembly is mounted on one side of the three blades, and the three blades are mounted on the outer side of the variable pitch assembly in a circumferential array shape; the transmission unit is mounted on one side of the variable pitch assembly; the gear unit is mounted on the other side of the transmission unit; the driving assembly is mounted on the other side of the gear unit; according to the propeller with the adjustable pitch ratio, a first locking shaft sleeve unit drives a first locking unit to move on one side of a transmission gear, a middle shaft is locked with a transmission main shaft, a second locking shaft sleeve unit drives a second locking unit to move towards the end close to the middle shaft, an inner shaft is locked with the middle shaft, and a first driving gear and a second driving gear are meshed with three variable pitch teeth at the same time; the three variable-pitch teeth are locked, the inner cavity gear of the variable-pitch assembly is kept relatively static during constant-speed sailing, and the angle stability of the blades is improved when the propeller rotates at a high speed.

    本发明公开了一种可调螺距比螺旋桨,涉及螺旋桨领域,包括三个叶片和若干螺栓,变桨组件,其安装于三个叶片一侧,且三个叶片呈圆周阵列状安装于变桨组件外侧;传动单元,其安装于变桨组件一侧;齿轮单元,其安装于传动单元另一侧;驱动组件,其安装于齿轮单元另一侧;该可调螺距比螺旋桨,通过锁止轴套单元一驱动锁止单元一向传动齿一侧移动,中间轴与传动主轴锁止,锁止轴套单元二驱动锁止单元二向靠近中间轴一端移动,内部轴与中间轴锁止,驱动齿一和驱动齿二同时与三个变桨齿啮合,三个变桨齿被锁止,在匀速航行时,变桨组件内腔齿轮保持相对静止,在螺旋桨高速旋转时,提高叶片的角度稳定。
