The controllable-pitch propeller pitch automatic deviation rectifying oil distributor comprises an oil distribution ring and an oil distribution shaft, a left oil groove, a middle oil groove and a right oil groove are formed in the oil distribution ring, the left oil groove and the right oil groove are communicated with each other, the middle oil groove is communicated with a pressure oil port P, and the right oil groove is communicated with an oil return port T; the oil distribution shaft is provided with an oil distribution port A and an oil distribution port B, the oil distribution port A is connected with the first oil way, the oil distribution port B is connected with the second oil way, and the oil distribution shaft is connected with a linkage rod; the oil distribution ring is arranged on the oil distribution shaft in a sleeving mode and connected with the oil distribution shaft in a sliding fit mode, the hydraulic pressure difference between the first oil way and the second oil way is changed through the relative position changes of the oil distribution port A and the middle and right oil grooves and the relative position changes of the oil distribution port B and the left and middle oil grooves, and the linkage rod is driven to reciprocate. In application, when offset distance occurs, the first oil way or the second oil way can automatically obtain hydraulic pressure, then the oil distribution shaft is driven to automatically recover a stable state, the purpose of follow-up deviation correction is achieved, and flow limitation is broken through. Therefore, the automatic deviation rectifying device not only can automatically rectify deviation, but also is good in stability.

    一种调距桨螺距自动纠偏配油器及其应用方法,包括配油环与配油轴,配油环内设有左、中间、右油槽,左、右油槽相互连通,中间油槽与压力油P口连通,右油槽与回油T口连通;配油轴上设有配油口A与配油口B,配油口A与第一油路相连,配油口B与第二油路相连,配油轴连接有联动杆;配油环套设于配油轴上,与配油轴滑动配合连接,通过配油口A与中间、右油槽以及配油口B与左、中间油槽的相对位置变化,改变第一、第二油路之间的液压差,带动联动杆进行往复运动;在应用中,出现偏距时,第一或第二油路会自动获得液压,进而带动配油轴自动恢复稳定状态,达到随动纠偏的目的,并且突破了流量限制。因此,本设计不仅可以自动纠偏,而且稳定性较好。
