The invention provides a split type propeller hub mounting and sealing structure of an underwater vehicle propeller. The split type propeller hub mounting and sealing structure comprises a front section propeller hub, a rear section propeller hub and a propeller shaft. The rear end surface of the front section propeller hub is matched with the front end surface of the rear section propeller hub, the outer portion of the front section propeller hub is connected with the propeller blades, and the inner portion of the front section propeller hub is connected with the propeller shaft. The rear section propeller hub is the remaining part of the whole propeller hub except the front section propeller hub, and the interior is connected with the propeller shaft. In the split type propeller hub mounting and sealing structure provided by the invention, the propeller hub is decomposed into the front section propeller hub and the rear section propeller hub, and the front section propeller hub and the rear section propeller hub are connected through the propeller shaft so that the front section propeller hub and the rear section propeller hub can rotate at the same rotating speed under the driving of the propeller shaft to form a fairing fluid line type; and the split type propeller hub mounting and sealing structure is easy to machine, convenient to mount and accurate in positioning on theshaft, and solves the problem that the tail end of the propeller hub is too thin and too long and is not beneficial to integrated machining and mounting.

    本发明提供了一种潜航器螺旋桨的分体式桨毂安装与密封结构,该分体式桨毂安装与密封结构包括前段桨毂、后段桨毂和螺旋桨轴;所述前段桨毂的后端面与后段桨毂的前端面吻合,前段桨毂的外部与桨叶连接,内部与螺旋桨轴连接;所述后段桨毂为整体桨毂除去前段桨毂后的剩余部分,内部与螺旋桨轴连接。本发明提供的分体式桨毂安装与密封结构中,桨毂分解为前段桨毂和后段桨毂,通过螺旋桨轴连接前段桨毂和后段桨毂,使前段桨毂和后段桨毂均能够在螺旋桨轴的带动下以相同的转速旋转,形成一光顺流体线型,该分体式桨毂安装与密封结构加工简单、安装便捷、在轴上的定位准确,解决了桨毂末端过细过长不利于一体化加工与安装的问题。
