Correct and timely maintenance of bearings is an important aspect of ensuring the normal operation of highway machinery. If the external spherical bearing is well maintained, it can work for thousands of hours or even longer; On the contrary, it will significantly reduce the service life of the outer spherical bearing, and even lead to serious accidents such as burning of the bearing pads and holding the shaft. Generally, the operating temperature of the lubricating oil for bearings should not be higher than 50 ℃. In order to ensure sufficient and reliable lubricating oil, it is necessary to timely or regularly inspect the oil level to keep it within the specified range. To maintain some cleanliness, timely replace according to the oil quality requirements. The failure of external spherical bearings should be analyzed on a case by case basis and eliminated in a timely manner. Common faults and handling methods of outer spherical bearings are as follows

In order to give full play to the bearing and maintain its proper performance for a long time, it is necessary to effectively carry out regular maintenance (regular inspection)

Through appropriate periodic inspections, it is important to detect faults early and prevent accidents before they occur, improving productivity and economy

When disassembling the bearing for inspection, first use photography and other methods to make appearance records. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing

The cleaning of bearings can be divided into rough cleaning and fine cleaning, and a metal mesh frame can be placed at the bottom of the container used

During rough cleaning, use a brush or the like to remove lubricating grease or adhesion in the oil. At this time, if the outer spherical bearing is rotated in oil, it may damage the rolling surface due to foreign matters

During fine cleaning, slowly rotate the bearing in oil and carefully perform it

The commonly used cleaning agent is neutral non aqueous diesel or kerosene, and sometimes warm lye is used as needed. Regardless of the cleaning agent used, it is necessary to filter frequently to keep it clean
