大冶铁矿有KY-310和45-R两种型号的牙轮钻机,其回转减速器中的齿轮和轴承原采用30号机械油油池润滑。由于回转减速器主轴与钻杆直接连接进行穿孔作业,又因油池润滑并不是完全闭式的,所以,在穿孔作业中网转减速器在轴下端密封盖中的密封圈与钻杆连接器之间常常发生漏油,造成钻架,机棚顶及钻架平台油污染严重,且要频繁加油,油量消耗很 Daye Iron Mine has KY-310 and 45-R two types of cone-type drilling rig, the slewing reducer gear and bearing the original No. 30 mechanical oil tank lubrication. Because the slewing reducer spindle and the drill pipe directly connected to the perforation operation, and because the sump lubrication is not completely closed, so in the punching operation in the shaft at the lower end of the sealing cap sealing ring and drill pipe connector Between the oil spills often occur, resulting in drill rig, roof and drill rig platform oil pollution is serious, and to frequent refueling, fuel consumption is very
