The invention discloses a convenient-to-maintain bearing for a single-point mooring rotary joint. The convenient-to-maintain bearing comprises an outer rotating assembly and an inner rotating assemblywhich are of a split structure, wherein the inner rotating assembly can rotate relative to the outer rotating assembly. The outer rotating assembly comprises a first outer ring, an outer ring assembly and a second outer ring which are sequentially arranged from bottom to top. An annular protrusion connected with the outer rotating assembly in a clamped mode is arranged in the center area of the outer circumference of the inner rotating assembly, and a rolling transmission component is arranged between the outer rotating assembly and the inner rotating assembly. The rolling transmission component comprises first rolling pieces arranged between the first outer ring and the inner rotating assembly and between the second outer ring and the inner rotating assembly, and second rolling pieces arranged between the outer ring assembly and the annular protrusion. According to the bearing for the single-point mooring rotary joint, the problem that all rotary joints need to be dismounted when thebearing is maintained is solved, maintenance is convenient, the service cycle of the bearing is effectively prolonged, and the economic practicability of offshore operation is effectively improved.

    本发明公开了一种方便维修的用于单点系泊旋转接头的轴承,包括分体式结构的外转动组件和内转动组件,内转动组件相对与外转动组件可相对转动,外转动组件包括自下而上依次设置的外环一、外环组件和外环二,内转动组件的外圆周中心区域设有与外转动组件卡接的环状凸起,外转动组件和内转动组件之间设有滚动传动部件,滚动传动部件包括设在外环一与内转动组件和外环二与内转动组件之间的第一滚动件、以及设在外环组件和环状凸起之间的第二滚动件。本发明的用于单点系泊旋转接头的轴承克服了维修该类轴承时必须拆除所有旋转接头的问题,便于维修,有效提高了轴承的使用周期和海上作业的经济实用性。
