水翼船翼柱自位球轴承与衬套配合的研究

Research on the fit between self-aligning ball bearing and bush on the kingpost of hydrofoil

将水翼船翼柱衬套外圆面设计成圆锥面，有利于工作状态时，翼柱自位球轴承球体内孔与衬套之间保持均匀的间隙，使润滑充分，磨损减少。

It is favorable to keeping the even fit clearance between the bush and the hole of the ball body of a self-aligning ball bearing on the kingpost,ensuring full lubrication,and reducing the wear of the originally cylindrical bush for the outside shape of a bush to be designed into the cone one.
