檢查

檢查交流發電機皮帶與任何配件皮帶是否有磨損或龜裂。 若皮帶狀況不佳,請更換皮帶。

依據維修手冊, "技術規格"內的資訊檢查皮帶張力。

皮帶鬆動所導致的打滑會降低傳動組件的效率。 皮帶鬆動所導致的震動會使下列機件產生不必要的磨損:

  • 皮帶

  • 皮帶盤

  • 軸承

若皮帶太緊,則會在組件上施加不必要的應力。 不必要的應力會降低組件的使用壽命。

更換

對於需要使用多重傳動皮帶的設備,請使用匹配組內的傳動皮帶進行更換。 更換一條匹配組內的傳動皮帶會使新的傳動皮帶承受較多的負載,因為較舊的傳動皮帶已拉伸變長。 新傳動皮帶上的額外負載會使新皮帶損壞。

交流發電機皮帶調整

(3) 安裝螺栓
(4) 安裝螺栓

  1. 鬆開安裝螺栓 (2)、 (3) 和 (4)。 鬆開調整螺帽 (1)。

  2. 旋轉調整螺帽 (1) 可增加或減少驅動帶的張力。

  3. 擰緊調整螺帽 (1)。 擰緊安裝螺栓 (2)、 (3) 和 (4)。

若已安裝新的驅動帶,在引擎以額定轉速運轉 30 分鐘之後,再次檢查驅動帶張力。 關閉引擎。 使用頻率工具檢查所安裝之交流發電機護板的張力。 目前的護板設計可讓您在不拆除驅動帶護板的情況下進行檢查。
