The invention relates to the technical field of hydraulic variable pitch propellers, in particular to a propeller hydraulic speed regulator. Which comprises a shell, one end of the shell is connected with an end cover, a speed regulator oil inlet, a speed regulator oil outlet and a propeller oil inlet are formed in the end cover, a lubricating oil supercharging device is arranged in the shell and divides the interior of the shell into a low-pressure oil cavity and a high-pressure oil cavity, the lubricating oil supercharging device comprises a hollow transmission shaft, and oil holes connected with different oil ways are formed in the transmission shaft. The end, away from the end cover, of the oil distribution rod is connected with an electric cylinder telescopic rod, and different oil ways are communicated by adjusting the position, in the transmission shaft, of the oil distribution rod. Lubricating oil is pressurized through the lubricating oil pressurizing device, and the lubricating oil can flow into different oil ways through mutual cooperation between the oil distributing rod and the transmission shaft, so that the pitch of the propeller is changed; the electric cylinder can accurately control the position of the oil distributing rod, the variable pitch of the propeller can be accurately and sensitively adjusted, and the structure is stable and reliable.

    本发明涉及液压变距螺旋桨技术领域,尤其是涉及一种螺旋桨液压调速器。包括壳体,壳体一端连接端盖,端盖上设有调速器进油口、调速器出油口和螺旋桨进油口,壳体内部设有滑油增压装置,将壳体内部分为低压油腔及高压油腔,滑油增压装置包括内部中空的传动轴,传动轴上设有连接不同油路的油孔,传动轴内部设有分油杆,分油杆远离端盖一端连接电动缸伸缩杆,通过调节分油杆在传动轴内部的位置连通不同油路。本发明通过滑油增压装置对滑油进行了增压,而分油杆与传动轴之间的相互配合能够使滑油流入不同油路,进而对螺旋桨进行变距;电动缸能够精确控制分油杆的位置,能够精准、灵敏的调节螺旋桨变距,结构稳定可靠。
