Generator Bearing - Inspect
拆卸轴承架。 检查以下项目:轴承架孔, 轴承外滚道 和 滚动元件。 在备用电源装置上,每 3 年周期必须检查一次轴承并更换润滑脂。 应检查轴承架衬套的失圆度、有无过量磨损,且轴承架的磨损台阶是否小于0.0762 mm ( 0.0030 in)。 如果没有轴承架衬套,则检查轴承架孔。 检查外滚道有无损坏、严重的腐蚀,是否运转平滑。 如有可能,应检查轴承元件。 有些双防尘罩滚珠轴承妨碍对轴承元件进行目视检查。 另一些双防尘罩滚珠轴承有一个卡环。 可将该卡环拆去,以便对滚珠轴承元件进行目视检查。
在双轴承发电机上,前轴承只有在拆卸驱动连接器后才能拆卸。 请参阅系统操作测试和调整拆解和组装, "连接器 - 拆卸",以了解用于发电机的拆卸驱动连接器的说明。
