起重機機構的潤滑 Lubrication of mechanisms

起重設備潤滑情況的好壞，直接影響起重機各機構的正常運行和生產工藝流程的正常進行，對延長機構壽命和促進安全生產有密切關系。因此，使用和維護保養必須經常檢查各潤滑點的潤滑情況，按時補充和更換潤滑油脂。

The lubrication condition of lifting equipment directly influences the normal operation of mechanisms of the crane and production technology process and has a close relationship with prolonging the lifespan of mechanisms and promoting safety production. Therefore, it is essential to regularly inspect the lubrication condition at all lubricating points and supplement and replace the lubricating grease on time.

(一)起重設備各潤滑點的分布 Distribution of all lubricating points of the lifting equipment

1.  吊鉤軸 hook shaft

2.  減速器 reducer

3.  軸承箱 bearing box

4.  電動機軸承 motor bearing

5.  夾軌器、齒輪絲桿和各節點 rail clamping device, screw rod of the gear and joints

(二)起重機必須采用合適的潤滑油脂，定期潤滑和及時更換。潤滑裝置和各潤滑點必須保持清潔。下表是各機構主要零部件潤滑時間的一般規定和推薦用的潤滑材料。

The crane must adopt suitable lubricating grease to regulary lubricate the machine and it should be replaced timely. The lubricating device and lubricating points should be kept clean. The following table is the general provisions of the main components of mechanisms and recommended lubricating materials.

注:   1.  表中所例SY系石油部部頒標準代號；

         SY listed in the table is standard code issued by Oil Ministry.

      2.  根據起重機工作的類型(分輕、中級等)的不同及工作地區以及場合的條件，可酌

情增加或減少規定的潤滑時間，表中系按中級工作類型給出的；

According to different types of work (light or intermediate rank) of the crane and conditions of operational area and occasions, it is allowed to increase or decrease the stipulated lubrication time. In the table, it bases on intermediate type of work.

       3. 潮濕地區因其親水性強不宜用納基潤滑脂；

         Sodium soap grease is not suitable to use in humid area because of its strong hydrophilic property.
