The invention relates to the technical field of variable-pitch propellers, in particular to a split type large-load bearing special for a variable-pitch propeller and the variable-pitch propeller. The split type heavy-load bearing special for the variable-pitch propeller comprises a bearing outer ring, a bearing inner ring and a ball assembly, the outer surface of the bearing outer ring is in interference fit with a propeller hub oversleeve of the variable-pitch propeller, and a ball sliding way is arranged on the inner side of the bearing outer ring; the ball assembly is installed in the ball slide way. The bearing inner ring comprises a first bearing inner ring and a second bearing inner ring, and the first bearing inner ring and the second bearing inner ring are both installed on the inner side of the ball assembly. The ball assembly is clamped by the bearing inner ring and the bearing outer ring, so that the ball assembly only performs axial rotation motion, and the combined bearing can realize the function of an angular contact ball bearing. The variable-pitch propeller is high in assembly efficiency, and meanwhile the light weight of the variable-pitch propeller is achieved.

    本发明涉及变距螺旋桨技术领域,尤其是涉及一种变距螺旋桨专用的分体式大载重轴承及变距螺旋桨。该变距螺旋桨专用的分体式大载重轴承,包括:轴承外圈、轴承内圈和滚珠组件,所述轴承外圈的外表面与变距螺旋桨的桨毂袖套过盈配合,所述轴承外圈的内侧设有滚珠滑道;所述滚珠组件安装在所述滚珠滑道内;所述轴承内圈包括第一轴承内圈和第二轴承内圈,所述第一轴承内圈和所述第二轴承内圈均安装在所述滚珠组件内侧。通过轴承内圈与轴承外圈将滚珠组件包夹,使滚珠组件只进行轴向旋转运动,组合后的轴承,能够实现角接触球轴承的功能。该变距螺旋桨装配效率高,同时实现了变距螺旋桨的轻量化。
