Disclosed are a bearing lubricating system and a micro gas turbine power generator set. The bearing lubricating system comprises a first oilway (17), a second oilway (18), a first bearing (20) coaxially arranged with a second rotation shaft (7), a second bearing (21), a bearing sleeve (14), an oil injection ring (15) and an abutting device (16), wherein the first oilway (17) runs through the bearing sleeve (14) to provide a lubricating oil supply passage for the first bearing (20); the second oilway (18) runs through the bearing sleeve (14) and the oil injection ring (15), so as to provide a lubricating oil supply passage for the second bearing (21); and the abutting device (16) respectively abuts against a positioning rabbet (142) of the bearing sleeve (14) and the oil injection ring (15). An axial force is applied to the oil injection ring (15) under the action of a pre-tightening force of the abutting device (16), so that the bearing sleeve (14) and the oil injection ring (15) always stay attached to the b
