Scraper speed reducer is mainly composed of upper box, lower box, one axis assembly, two axis assembly, three axis assembly, four axis assembly, bearing, gear, seals and so on. At present, the different parts of the scraper reducer are mainly lubricate by grease, oil immersion and splash. The main lubricants of plate scraper reducer are no. 150 extreme pressure gear oil or No. 22 hyperbolic gear oil and No. 2 sodium base grease. The bearings and gears on the second, third and fourth shafts of the scraper reducer are lubricated by splashing oil. Scraper reducer in the oil, follow the strict and accurate principle, can not be mixed with different grades of lubricating oil. Lubricating oil shall be loaded from the top viewing hole when the scraper reducer is being lubricated, and the amount of lubricating oil shall be kept at one third of the circle arc bevel gear. After the new reducer is put into use for 200 hours, the oil inside the reducer should be released, cleaned and changed. After the initial cleaning and oil change, wash and oil change every 1000 hours. When the reducer is working, it should be cleaned and changed for oil when the following conditions occur visually. Oil appears to deposit dirt, particulate sediments. The oil darkens, turns black, and even gives off an unpleasant smell. Brown gelatinous material appears on parts of reducer, corrosion marks appear on the surface of parts. Oil body flow difficulty. There are some situations need to be tested, in the reducer lubricating oil sundry content more than 2%, metal abrasive more than 0.5%, water content more than 2%, the need to clean oil change. In strict accordance with the requirements of the timely scraper reducer lubrication, cleaning and oil change can prolong the cycle of the reducer. Henan Shuangzhi Machinery Equipment Co., LTD.
