“…The utility model does not need an electric excitation device, and has the advantages of light weight, high efficiency and good reliability [4] . In direct-driven wind power generation system, the direct coupling between the wind turbine and the generator, because there is no gearbox and its accessories, the transmission mechanism is greatly simplified [5] , reducing the number of parts of the unit, thus reducing the failure rate, the reliability is greatly improved, and the danger of oil leaking into the sea water is reduced, the maintenance work of the generator is reduced, and the noise is reduced, which is friendly to the electric network [6] . In addition, the short board of Direct Drive technology also includes the heat dissipation of the generator, the head load is too big, etc.…”

In order to further improve the reliability of wind turbine operation, reduce manufacturing, installation and maintenance costs, and make the size of the gearbox further reduced, in this paper, the gear box design of 15MW offshore semi-direct-driven wind turbine is studied. First, analyze the development trend and demand, draw up the basic transmission plan, then, carry on the gear structure design, use the software modeling, the motion analysis and carry on the check, the life analysis, finally, the design of sealing mode, design box, end cover structure, determine the fastener, connection, design of dust-proof program and design of lubrication. This reduces the weight and volume of the main engine of the medium-speed transmission mechanism of the wind turbine. The obvious benefits are lower overall load, lower difficulty in manufacturing, transportation and installation, lower cost and controllable technology, the market prospects are broad and competitive.
