我厂使用的LVG/S60框式平移砂锯是前西德卡尔迈尔公司生产的。96年在该机运行中监听到一种异常声音,进一步探查是一个框架行走轮发出的响动,于是马上停机拆开轮盖检查,发现轴承已坏。我们拆下两个液压弓形架,卸开轮轴总成把它吊到空地上放平,然后拆卸行走轮。两套92214轴承已经破裂,轴承隔套也裂成数块,轴端部用于锁轴承的M70×2螺纹已被碾磨出4mm深的沟痕,无法继续使用。 该轴直径φ90mm总长3720mm,重新加工一根是
The LVG/S60 translating sand saw used by our factory is produced by the former West Carlmeier company. In 1996, during the operation of the aircraft, an abnormal sound was detected. Further exploration was the ringing motion of a walking wheel of the frame. So immediately stopped the wheel cover and checked that the bearings had been damaged. We removed the two hydraulic bows, dismantled the axle assembly and lifted it to the empty floor, and then disassembled the wheels. Two sets of 92214 bearings have been broken and the bearing spacers have also been split into several pieces. The M70×2 thread used to lock the bearings at the end of the shaft has been grinded to a groove mark of 4 mm deep and cannot be used. The shaft diameter φ90mm total length 3720mm, reprocess one is
