电动葫芦门式起重机机构的润滑
起重机机构的润滑 Lubrication of mechanisms
起重设备润滑情况的好坏，直接影响起重机各机构的正常运行和生产工艺流程的正常进行，对延长机构寿命和促进安全生产有密切关系。因此，使用和维护保养必须经常检查各润滑点的润滑情况，按时补充和更换润滑油脂。
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)起重设备各润滑点的分布 Distribution of all lubricating points of the lifting equipment
1. 吊钩轴 hook shaft
2. 减速器 reducer
3. 轴承箱 bearing box
4. 电动机轴承 motor bearing
5. 夹轨器、齿轮丝杆和各节点 rail clamping device, screw rod of the gear and joints
(二)起重机必须采用合适的润滑油脂，定期润滑和及时更换。润滑装置和各润滑点必须保持清洁。下表是各机构主要零部件润滑时间的一般规定和推荐用的润滑材料。
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.
润滑 部位 Lubrication part | 补油周期 Cycle of supplementing lubricating oil | 换油周期 Cycle of replacing lubricating oil | 润滑油（脂）牌号 Mark of lubricating oil (grease) | 标准号 Standard number | 加油量 Quantity of supplementing | ||||||
一 周 One week | 半 月 Half a month | 一 月 One month | 一 季 Three months | 半 年 Half a year | 一 年 One year | ||||||
QSC减速器 QSC reducer | √ | √ | ≥10℃，220号工业齿轮油 ≥10℃，No. 220 industrial gear oil | SY1172－88 | |||||||
＜10℃，150号工业齿轮油 ＜10℃，No. 150 industrial gear oil | |||||||||||
车轮、承座、滑轮及其它部位的滚动轴承 Rolling bearing of wheel, bearing, pulley and other parts | √ | √ | 3号钙基润滑脂 No. 3 albany grease | 轴承座空间1/2～2/3 | |||||||
电动机轴承 Motor bearing | √ | ZL－2锂基润滑脂 ZL－2 lithium base grease | SY1412－75 | 轴承座空间1/2～2/3 Space of bearing block 1/2 to 2/3 | |||||||
注: 1. 表中所例SY系石油部部颁标准代号；
SY listed in the table is standard code issued by Oil Ministry.
2. 根据起重机工作的类型(分轻、中级等)的不同及工作地区以及场合的条件，可酌
情增加或减少规定的润滑时间，表中系按中级工作类型给出的；
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. 潮湿地区因其亲水性强不宜用纳基润滑脂；
Sodium soap grease is not suitable to use in humid area because of its strong hydrophilic property.
