Abstract:
To provide a lubricating structure for a planetary reduction gear, capable of circulating grease to a power transmission part to be lubricated without splashing therearound in company with the turn of the power transmission part.
Grease is filled in abutting portions P1, P2, P3 among a sun gear 3, a planetary gear 4, and inner rings 5a, 5b for reducing mutual wear to actualize smooth frictional transmission. A pair of shielding plates 6a, 23 are provided on both axial sides via the abutting portions P1, P2, P3 for covering the abutting portions P1, P2, P3 via gaps. To the other shielding plate 23, a blade portion is attached so that the grease flows toward one shielding plate 6a with the turn.
