[Abstract]:In this paper, the reliability design of high-power wind power gearbox is studied in the light of the project of transferring AEROgear technology of RENK Company. The main research contents are as follows: 1. The development status and trend of wind power gearbox are analyzed. This paper introduces the market capacity and future development trend of the global and Chinese markets, introduces the common failure modes of wind power gearboxes and the structural design schemes at home and abroad, and expounds the practical significance of the design and research of high-power wind power gearboxes. Especially, the large-scale application of high-power wind power gearbox will provide a new research direction for the development of offshore wind power gearbox, which determines the research direction of this paper. 2. The general structure of fan and gearbox at home and abroad is analyzed. According to the parameter requirement of the whole machine factory and the AEROgear structure scheme of RENK Company, the gear box structure scheme is determined to be the first grade composite star class parallel class, and the gear matching calculation is carried out according to the transmission ratio requirement, and the analysis and calculation model of the gear force is established. The mechanical analysis and calculation of all levels of transmission are carried out. The contact safety factor and bending safety factor of gear at all levels are designed and checked by Kisssoft software. 3. The coordinate system acting on gearbox, the type of fan load and its influence on gearbox are analyzed. The treatment method of fan load is introduced, and the equivalent torque and linear cumulative fatigue damage theory, Miner theory, are expounded. Based on the linear cumulative fatigue damage theory, the calculation model of equivalent torque and use coefficient is established, and the use coefficient of this research object is calculated. 4. This paper analyzes the bearing selection method based on basic rated life and the method of reducing load grid in load processing. The calculation method of centralized adjacent load grid, weighted average life and weighted average life is emphasized. The methods of equivalent bearing load, maximum rolling load, contact pressure calculation and contact stress calculation are discussed. The bearing type selection and life calculation are carried out together with bearing professional company FAG. 5. The principle and calculation method of power loss and efficiency are analyzed. The measures to improve the heat load capacity and the design requirements of lubricating system are expounded. The principle diagram of lubrication system is established, and the lubrication principle and main control signal parameters are discussed. The rationality of the design power loss is verified by experiments.
