[0002] Planetary gear bearings are intermediate bearings used to connect planetary gears and gear shafts, which allow the planetary gears to be stably mounted on the shaft and to rotate smoothly. Gear bearings are generally composed of an outer ring, an inner ring, a retaining cage, and rolling elements. In order to reduce the wear between the rolling elements, lubricating oil needs to be added to the bearings to lubricate them. At present, when lubricating the bearings, lubricating oil is generally injected into the bearings through a syringe.
