C9 Generator Set Caterpillar


Generator Bearing - Inspect

Usage:

C9 LN9

LC

LC5、 LC6 和 SR5 發電機採用的滾珠軸承包含潤滑脂。 此潤滑脂會受到老化作用影響。 如果發電機儲放超過 1 年且未轉動轉子,便可能需要更換新的滾珠軸承。 這些軸承出廠時都已經塗上潤滑脂。 因此,您在現場使用時,無須加上任何其他潤滑。 取下所有必要的外蓋,以便檢查發電機的後方軸承。 前方軸承可透過風扇篩網檢視。 目視檢查是否有顯著的損壞、腐蝕,或者軸承套管四周有過量的淨化潤滑脂。 出現少量的淨化潤滑脂是合乎標準的。 潤滑脂如果覆蓋在支架或線圈上,則為過量。

軸承檢查應包含振動資料的集合。 請參閱此操作及維護手冊發電機組振動, " - 測試/記錄",以取得更多有關檢查振動等級的資訊。

執行這項檢查作業時,也應測量並記錄軸承溫度。 請參閱此操作及維護手冊發電機軸承溫度, " - 測試/記錄",以取得更多有關檢查振動等級的資訊。

如果檢查結果顯示軸承無生鏽或腐蝕,起動時也沒有出現噪音或過度振動,則無須更換軸承。

A 形機架與 R 形機架

用於 A 形機架、 R 形機架發電機的軸承為密封軸承,且不需要添加潤滑脂。
