我公司现有轮胎式起重机65台、门式、桥式起重机46台。起重机械由于使用在重载、工作频繁、承受冲击载荷工况下,因此,减速器齿轮副属于低速、重载传动、工作条件恶劣、温差变化大、工作中启、制动频繁、振动大等工况下工作。所以,减速器极易产生润滑油泄漏现象,特别是立式减速器,泄漏现象更为严重。据检查我公司上述设备中绝大部分都存有润滑油泄漏问题。因此,如何保证这些设备中减速器润滑良好,又不泄漏是我们要加以解决的问题。目前国内已开发出多种新型润滑、密封材料,其中半流体润滑脂在各类起重机减速器中
My company currently has 65 wheeled cranes, portals and 46 bridge cranes. Due to the use of heavy-duty cranes, heavy work, and under impact load conditions, the gears of the reducer are low-speed, heavy-duty transmissions, poor working conditions, large temperature differences, frequent starts and brakes during operation, and high vibrations. Work under other conditions. Therefore, the reducer can easily produce leakage of oil, especially the vertical reducer, the leakage phenomenon is more serious. According to our inspection, most of the above-mentioned equipments of our company have oil leakage problems. Therefore, how to ensure that the speed reducer in these devices is well lubricated without leakage is a problem that we need to solve. At present, a variety of new types of lubricants and sealing materials have been developed in China, of which semi-fluid greases are used in various types of crane decelerators.
