The invention relates to a watertight box body of a shaft type oil distributor. An upper box body and a lower box body are fixedly connected into a whole through screws, and the two ends of the upper box body and the two ends of the lower box body are installed on an oil distribution shaft through deep groove ball bearings respectively. Two ends of the upper box body and the lower box body are fixedly connected with sealing end cover assemblies; the oil distribution shaft corresponding to the sealing end cover assemblies is fixedly connected with an oil seal shaft sleeve; oil through holes are formed in the two ends of the upper box body respectively, and outlets of the oil through holes are formed between the deep groove ball bearing and the sealing end cover assembly; the upper surface of the upper box body is connected with two cooling oil pipes arranged in the upper box body through cooling oil connectors, the two cooling oil pipes are connected with oil through holes in the two ends of the upper box body respectively, and cooling oil is sprayed through the oil through holes between the deep groove ball bearings and the rotary oil seals at the two ends of the two cooling oil pipes respectively. Meanwhile, the deep groove ball bearing and the rotary oil seal are cooled and lubricated; an oil through hole is formed in the contact surface of the lower box body and the deep groove ball bearing. The shaft type oil distributor can collect oil liquid under the normal working condition, and the working requirements of a controllable-pitch propeller device under the normal working condition and the soaking working condition are met.

    本发明涉及一种轴式配油器水密型箱体,上、下箱体通过螺钉固定连接成一体,两端分别通过深沟球轴承安装于配油轴上;上、下箱体的两端固定连接密封端盖组件,密封端盖组件对应的配油轴上固定连接油封轴套;上箱体的两端分别设置通油孔,通油孔的出口设置于深沟球轴承和密封端盖组件之间;上箱体上面通过冷却油接头连接设置在上箱体内的两根冷却油管,两根冷却油管分别与上箱体的两端的通油孔相连接,冷却油通过两根冷却油管分别两端的深沟球轴承和旋转油封之间的通油孔喷淋,同时给深沟球轴承和旋转油封冷却、润滑;下箱体与深沟球轴承接触面设置通油孔。本发明能够实现轴式配油器在正常工况下收集油液,满足调距桨装置正常及浸水工况工作要求。
