M7130磨头结构如图所示,甩油环1经过长期运转后,内孔表面逐渐磨光,当它靠近轴承盖3的端面时,易产生磨头主轴4带不动甩油环1转动,使主轴得不到正常的润滑,以至抱瓦。为此,在修理中将甩油环1内孔表面用手锯锯出1×1×30°间隔5毫米的网纹,16～φ5甩油孔在外圆柱面的圆周方向锯长15～20毫米,深1毫米的小沟,以增大甩油量。同时,在主轴上加一个φ65×φ5的O型油封2,靠
M7130 grinding head structure shown in the figure, the oil thrower 1 after long-term operation, the inner hole surface gradually polished, when it is close to the end face of the bearing cover 3, easy to produce grinding head spindle 4 with fixed oil thrower 1 rotation, So that the spindle can not get the normal lubrication, and even hold the tile. To this end, in the repair will be thrown a hole in the surface of the oil ring 1 hand saw saw 1 × 1 × 30 ° interval 5 mm of the mesh, 16 ~ φ5 rejection oil in the cylindrical surface of the circumferential saw length of 15 to 20 mm , 1 mm deep groove to increase the rejection of oil. At the same time, in the spindle plus a φ65 × φ5 O-ring seal 2, by
