SWIVELING DEVICE FOR CONSTRUCTION MACHINERY

摘要

PROBLEM TO BE SOLVED: To efficiently lubricate a bearing for planetary gears which rotatably supports each planetary gear of a planetary gear reduction mechanism.

SOLUTION: A doughnut-shaped guide member 38 that covers the meshing section between the sun gear 17 and the planetary gears 18 and that receives lubricating oil that spatters from the meshing section and leads the lubricating oil to a planetary gear bearing 20 is provided at a position above the planetary gear reduction mechanism 16. As a result, the lubricating oil that spatters from the meshing section of the sun gear 17 and the planetary gears 18 is efficiently led to the planetary gear bearing 20 via the doughnut-shaped guide member 38.
