The lubrication and maintenance methods of the gear mainly include the following aspects to ensure the normal operation of the gear: lubricant selection: according to the conditions of use and running speed of the gear, choose the appropriate lubricant. Commonly used lubricants include lubricating oils and greases, and their viscosity and additive characteristics need to be determined according to the working environment and requirements. Oil filling and oil change cycle: According to the equipment manufacturer’s recommendations or actual conditions, regular oil filling and oil change operations to maintain the good performance of the lubricant. At the same time pay attention to comply with the corresponding operating temperature and operating speed requirements. Gear cleaning: Regularly clean the gear surface to remove dust and dirt, and avoid impurities entering the lubrication system. Brush, wipe and other tools can be used to clean, and use the appropriate cleaning agent. Check gear wear: Check gear regularly for wear, as well as possible damage and cracks. If obvious wear or failure is found, repair or replacement measures should be taken in time to prevent further damage. Regular maintenance: Regular maintenance and maintenance of the gear, including tightening bolts, checking bearing conditions, coupling clearance, etc. Timely treatment of equipment vibration, temperature rise and other anomalies to avoid resulting in reduced gear life. Monitoring and recording: Use the corresponding monitoring instrument to monitor the operating status of the gear, and record and analyze the data in time. Through monitoring and analysis, the life of the gear can be predicted and the necessary maintenance measures can be taken in advance. In short, regular lubrication and maintenance, cleaning gear, checking wear, regular maintenance, monitoring and recording are important methods to ensure the normal operation of gear. Through scientific maintenance and maintenance measures, the service life of the gear can be extended, the work efficiency can be improved, and the occurrence of failure and downtime can be reduced.
