Novel water lubrication on-shaft oil distributor for adjustable propeller

The novel water lubrication on-shaft oil distributor comprises an inner oil pipe, a feedback rod, a rotor, an oil distribution shaft and a stator, one end of the inner oil pipe is fixedly connected with the feedback rod, the inner oil pipe is communicated with the feedback rod, the feedback rod penetrates through the inner side of the rotor and is in sliding fit with the rotor, the rotor is installed in a middle hole of the oil distribution shaft, and the stator is installed in the middle hole of the oil distribution shaft. The rotor and the oil distribution shaft are axially fixed; the stator is hollowly sleeved on the oil distribution shaft; an outer oil pipe is further included, the inner oil pipe is sleeved with the outer oil pipe, and one end of the outer oil pipe extends into the middle hole of the oil distribution shaft and is fixedly connected with the rotor. According to the oil distributor, the double-pipe structure is adopted to form the three oil cavities, oil leaked from the first oil port and th
