破碎机(PYZ—2200中碎)属部控设备之一,其运行的正常与否,将直接影响到我矿的正常生产。 近年来,发现中碎机底座150孔与碗形轴承架1 500轴座配合间隙增大,严重超差(主要表现在传动轴方向和与传动轴90°方向4个点),碗形轴承架轴座与底座孔在设备运行过程中发生摇摆运动,互相摩擦,加速了底座孔与碗形轴承架轴座的磨损,使得配合间隙增大(最大间隙达5mm,具体间隙及磨损情况待年底检修系统停车后落实),整机响声、振动加大,是中碎机的一大隐患。
Crusher (PYZ-2200 in the broken) is one of the Ministry of control equipment, the normal operation or not, will directly affect the normal production of mine. In recent years, it was found that the gap between the 150 holes of the crusher base and the shaft seat of the bowl-shaped bearing bracket 500 increased greatly and exceeded the tolerance (mainly in the direction of the transmission shaft and 4 points in the direction of 90 ° with the transmission shaft) Pedestal and base hole in the equipment during the operation of rocking movement, friction with each other, accelerating the base hole and bowl-shaped bearing rack shaft wear, making with the gap increases (the maximum gap of 5mm, the specific gap and wear to be overhaul the end of the year System stop after implementation), the whole machine sound, vibration increased, is a major risk in the broken machine.
