The invention discloses a marine fabricated stern shaft and stern shaft sleeve connecting structure. The marine fabricated stern shaft and stern shaft sleeve connecting structure comprises a stern shaft body, a stern shaft sleeve, a fabricated contact roller and an assembling assembly. An assembly type contact roller is installed in an assembly groove, a rotating groove in one end of the assembly type contact roller is connected to a positioning protruding block in a sleeving mode, then an opening and closing rod is rotated, the opening and closing rod drives a built-in rotating column to rotate, the built-in rotating column rotates and drives two moving blocks to horizontally move, and therefore the two moving columns are driven by a driving block to relatively horizontally move; and the end of the movable column is inserted into a rotating groove in the other end of the assembly type contact roller, so that the assembly type contact roller is positioned, meanwhile, the assembly type contact roller rotates between a positioning convex block and the movable column, and the outer side of the periphery of the stern shaft body can be subjected to abutting positioning through the multiple assembly type contact rollers. And a rotary contact positioning structure is formed, abrasion and friction high temperature are reduced, and meanwhile mounting and dismounting are very convenient.

    本发明公开了一种船用装配式艉轴和艉轴套连接结构,包括艉轴本体、艉轴套、装配式接触辊、装配组件;本发明将装配式接触辊安装于装配槽内,使得装配式接触辊一端的转动槽套接于定位凸块上,然后通过启闭杆转动,启闭杆带动内置旋转柱转动,内置旋转柱转动并驱动两个移动块平移,如此通过驱动块带动两个移动柱相对平移移动,并使得移动柱的端部插接于装配式接触辊另一端的转动槽上,如此使得装配式接触辊形成定位,同时装配式接触辊在定位凸块和移动柱之间转动,如此艉轴本体的四周外侧可以通过多个装配式接触辊进行抵接定位,当艉轴本体转动时,形成了转动接触的定位结构,降低了磨损和摩擦高温的产生,同时本发明安装和拆卸十分的便利。
