Air hammer bearing lubrication road improvement

The C41-159 air hammer main shaft bearing (Fig. 1) is lubricated, and the oil transmitted from the oil pool 9 is transmitted to the pinion gear 1 by the large gear 8, so that the bearing 6 is used for lubrication. However, since the oil flowing to the bearing has no loop or place, the oil pressure is getting higher and higher, and the accumulated oil eventually exceeds the oil damper 1 or oozes out along the gap between the oil dam 1 and the retaining ring 2 (Fig. 2).
