一、吸油盘滤网安装不平，吸油盘吸入空气，造成润滑油中断而烧瓦。二、滤清器过脏，堵塞油路，使轴瓦得不到润滑而烧瓦。三、主轴瓦安装不正，瓦片堵塞机体油孔，切断或大大减少润滑油供应量而引起烧瓦。四、轴瓦间隙过大过小。过大，润滑油容易流失，形不成油膜；过小，润滑 First, the uneven installation of the suction plate filter, suction disk suction air, resulting in broken oil and burning tile. Second, the filter is too dirty, clogging the oil, so that the bearing is not lubricated and burning tile. Third, the main bearing installation is not correct, the blockage of the body oil hole, cut off or greatly reduce the supply of lubricating oil caused by burning. Fourth, the bearing clearance is too small. Too large, lubricating oil easily lost, can not form oil film; too small, lubrication
