Bearings play an important role in industrial equipment. Often the quality of the bearing also determines the operating efficiency of the entire equipment. In order for the bearing to fully perform its proper performance, it should be regularly maintained and maintained. Appropriate inspection can find faults in time, prevent problems before they occur, and improve the efficiency of the entire equipment.
1. Cleaning. When removing the bearing for inspection, make a record of its appearance by photography. In addition, confirm the amount of remaining lubricant and sample the lubricant before cleaning the bearing. There are two types of bearing cleaning: rough cleaning and fine cleaning. You can put a metal grid on the bottom of the container. When performing rough cleaning, use a brush or the like to remove grease or stickies in the oil. Be careful of the rolling surface due to foreign matter. During fine washing, slowly rotate the bearing in oil, and it must be done carefully.
2. Check for bearing failure. It is very important to improve the productivity and economy by identifying or predicting the failure of the bearing during operation without disassembly inspection. There are three main recognition methods: First, voice recognition, which requires extensive experience, must be adequately trained to recognize bearing and non-bearing sounds. To this end, this work should be carried out by a person as far as possible. The sound of the bearing can be clearly heard by using a listener or a listening stick on the housing. Second, the identification of operating temperature, this method is limited to the occasion where the operating state does not change much. For this reason, continuous recording of temperature is necessary. When a fault occurs, not only the temperature rises, but also irregular changes. Third, lubricant identification. Sampling and analysis of lubricants is performed based on whether the degree of contamination is mixed with foreign matter or metal powder. This method is particularly effective for bearings or large bearings that cannot be observed close to.
