The invention discloses an automatic propeller speed regulation control device which comprises an oil way control assembly, a centrifugal speed regulation assembly and a spring regulation assembly. The oil way control assembly comprises an oil distribution valve, an oil distribution bushing arranged outside the oil distribution valve in a sleeving mode, an oil distribution bushing arranged outsidethe oil distribution bushing in a sleeving mode and provided with a U-shaped section, an upper bearing, a lower bearing, and a shell which sleeve the oil distribution bushing. The upper end of the oil distribution valve is connected to a speed regulation spring, and the lower end abuts against a speed regulator balance weight. When the oil distribution valve is static, a bulge I seals a lower high-pressure oil hole, and a bulge II seals a middle ring oil hole; when the oil distribution valve moves downwards, the lower high-pressure oil hole is communicated with an oil outlet ring cavity, anda first oil cavity is further communicated with a large-distance oil way; and when the oil distribution valve moves upwards, the lower high-pressure oil hole is communicated with a high-pressure oil ring cavity, and a second oil cavity is further communicated with the large-distance oil way. The oil distribution valve is small in size, low in weight, high in response speed, small in inertia, capable of adjusting the speed in place at a time and high in adjusting precision, the stability of a system is guaranteed, and the service life is prolonged.

    本发明公开了一种螺旋桨自动调速控制装置,包括油路控制组件、离心调速组件和弹簧调节组件;油路控制组件包括分油活门、套在分油活门外的分油衬筒、套在分油衬筒外的截面为U型的分油衬套、上、下轴承和套在分油衬套外壳体;分油活门的上端连接在调速弹簧上,下端抵在调速器配重上;分油活门静止时,凸起Ⅰ封闭下高压油孔,凸起Ⅱ封闭中环油孔;分油活门下移时,下高压油孔与出油环腔连通,第一油腔还与大距油路连通;分油活门上移时,下高压油孔与高压油环腔连通,第二油腔还与大距油路连通。本发明的分油活门体积小、重量轻,响应速度快,惯性小,调节速度一次到位,调节精度高,保证了系统的稳定性,增加了使用寿命。
