The invention provides a controllable-pitch propeller oil distribution sealing device with a cooling function. The controllable-pitch propeller oil distribution sealing device comprises an oil distribution shaft and an oil distribution sealing sleeve arranged outside the oil distribution shaft in a sleeving mode. A central annular oil groove and an axial oil hole are formed in the middle of the inner wall of the oil distribution sealing sleeve, and an ahead oil port, a back-up oil port, a cooling oil inlet and a cooling oil outlet are formed in the outer wall of the oil distribution sealing sleeve; the cooling oil inlet and the cooling oil outlet are arranged along the circumferential direction of the central annular oil groove and are communicated with a central annular oil groove; the ahead oil port and the back-up oil port are formed in the two axial sides of the oil distribution sealing sleeve and communicate with the inner wall of the oil distribution sealing sleeve and an oil way in the oil distribution shaft. According to the invention, the oil distribution sealing function of the controllable-pitch propeller is achieved, meanwhile, heat generated by friction of the oil distribution sealing pair is forcibly cooled, the temperature of the oil distribution sealing pair is effectively reduced, abnormal abrasion and ablation caused by heat accumulation and temperature rising of the oil distribution sealing pair are eliminated, and the working performance reliability of the oil distributor of the controllable-pitch propeller is improved.

    本发明提供了一种具有冷却功能的调距桨配油密封装置,包括配油轴和套置在配油轴外的配油密封套;配油密封套内壁中部设有中心环形油槽和轴向油孔,配油密封套外壁开设有正车油口、倒车油口、冷却进油口和冷却出油口;冷却进油口和冷却出油口沿中心环形油槽周向设置,并与所述中心环形油槽连通;正车油口和倒车油口设置在配油密封套轴向两侧,正车油口和倒车油口均与所述配油密封套内壁和配油轴内部油路连通。本发明实现调距桨配油密封功能的同时,对配油密封副摩擦产生的热量进行了强制冷却,有效降低了配油密封副的温度,克服了配油密封副因热量聚集和温度升高而导致的异常磨损和烧蚀,提高了调距桨配油器的工作性能可靠性。
