高炉无料钟炉顶传动齿轮箱工况恶劣,在重载、高温、灰尘和高炉煤气的复合作用下长年运行,为防止 其突发故障,在设备运行期间对其进行了振动和油脂检测,并采用频谱和光谱手段对数据进行分析处理;在设备 解体后对故障部件进行了材质化验,研究表明:大多数炉顶传动齿轮箱停止运行是由于回转支承卡死造成的,回 转支承卡死的原因之一是保持架破损,之后轴承滚柱在运动过程中发生错位,个别滚柱的运动状态由滚动变为 滑动.最后造成滚柱因相互之间挤压而产生破损,导致齿圈的转动严重受阻甚至卡死.
Blast furnace without bell Top transmission gearbox bad condition, in the heavy load, high temperature, dust and blast furnace gas under the combined effect of long years of operation, in order to prevent its sudden failure, during equipment operation of its vibration and grease testing , And the data were analyzed by spectrum and spectroscopy. After the equipment was disassembled, the materials of the failed parts were tested. The results showed that most of the roof transmission gearboxes were stopped due to the jamming of the slewing bearing and the slewing bearing stuck Is one of the reasons for the cage damage, after the bearing roller in the movement occurred during the dislocation, the individual roller movement from sliding to sliding. The final result of the roller due to the mutual squeeze and damage, resulting in ring gear Rotation severely blocked or even stuck.
