Planetary mechanism lubrication flow distribution structure connected through spline

The invention belongs to the field of mechanical design, and particularly relates to a planetary mechanism lubrication flow distribution structure connected through a spline, which comprises a transmission shaft 1, a planet carrier 2, a planet wheel 5, a planet wheel shaft 4, a planet wheel bearing 6, a flow distribution sleeve 3 and a positioning plug screw 7. An axial positioning step is additionally arranged for the planet carrier 2 through the flow distribution sleeve structure, a lubricating oil way is prevented from directly penetrating through a spline connecting part, a spline gap of the lubricating oil way between the transmission shaft 1 and the planet carrier 2 is eliminated, leakage of lubricating oil in the oil way is reduced, and the lubricating effect is improved. 本发明属于机械设计领域，具体涉及一种通过花键连接的行星机构润滑配流结构，包括传动轴1、行星架2、行星轮5、行星轮轴4、行星轮轴承6、配流套3、定位螺塞7。本发明利用配流套结构为行星架2增加了一个轴向定位台阶，避免了润滑油道直接穿过花键连接部位，消除了润滑油路在传动轴1与行星架2之间的花键间隙，降低润滑油在油路中的泄露，改善润滑效果。
