Description

Technical Field

[0001] The utility model relates to the technical field of equipment support, in particular to an automated disassembly and assembly system for a planetary gearbox rotating assembly. Background Art

[0002] Currently, the planetary gearbox rotating components produced by Santasalo for nuclear power plant circulating water pumps are large, heavy, and difficult to disassemble and assemble. The entire gearbox rotating component weighs approximately 7,000 kg. During maintenance, the planetary gears are disassembled and assembled using a forklift, U-shaped clamps, and pallets, with the assistance of at least six personnel. The forklift's low control precision and large installation errors during disassembly and assembly can easily damage and scratch the thrust discs at the bottom of the planetary gears in the gearbox. Furthermore, personnel must monitor the travel height between the forklift and the planetary gears, posing a high industrial safety risk and a heavy labor burden. The long hours also pose a significant threat to workers' health. Utility Model Content
