PURPOSE:To directly lubricate to the bottom of teeth and improve the condition of their meshes without causing any problem in strength and weight limitation by forming a lubricating orifice reaching to the bottom of teeth from an oiling pocket which is formed on an end of root side by partially reducing the inside diameter of the teeth forming part of a spacer. CONSTITUTION:Inner teeth are formed on a sleeve 1 fastened on a shaft 3. An oiling pocket 9 is formed on an end face of root side of an outer teeth forming part 2a meshing with the inner teeth, and an oiling orifice 10 reaching from the pocket to the bottom of the outer teeth is formed to supply oil supplied from an oiling pipe 6 to a teeth meshing part 5. Therefore, oil can be directly fed to the bottom of teeth without impairing the stability of the system as a high speed revolving body, and the lubrication can be stabilized without any accumulation of sludge in the teeth meshing part resulting from an oil basin. |
