Preparation work: including wearing appropriate labor protection equipment such as work clothes, safety helmets, gloves, etc. At the same time, it is necessary to identify and evaluate the hazards in the work, and take corresponding safety measures, such as applying for power outages and locking control switches, to ensure work safety.
Dismantling old bearings: Firstly, it is necessary to dismantle the protective cover, coupling connectors, etc., in order to access the roller bearings. Use appropriate tools such as wrenches, hammers, and possible lifting equipment to gradually dismantle old bearings. This step may require consideration of the type of fit between the bearing and the drum seat (such as interference fit), and may require the use of specialized tools or techniques, such as hydraulic jacks or special dismantling fixtures.
Cleaning and Inspection: The disassembled drum and bearings need to be cleaned and inspected to determine if they can be reused or need to be replaced. This includes cleaning the dirt on the drum and bearings, as well as measuring the size and condition of the bearings.
Install new bearings: Clean and inspect the new bearings to ensure they meet specifications and requirements. Use appropriate lubricant to install the new bearing onto the drum and ensure that the bearing is correctly aligned and secured. This step may require the use of a press or specialized tools to assist with installation. 46
Complete installation and testing: After installation, conduct necessary tests to ensure that the bearings are functioning properly without any abnormal noise or vibration. After passing the test, clean up the work site and complete the replacement work.
The entire process needs to be strictly carried out in accordance with safety operating procedures to ensure personnel safety, while ensuring the quality and efficiency of the replacement work.
