The Research Of Accelerating Device Of Wind-Power-Generating

The wind-driven generating, which is developed to instead the limited fossil fuel and avoid the pollution it causes to the environment, is one of the new energy proposals searched for realizing continuous development. As the core gearing in the wind-driven generating system, speeding device is essential to breeze electric field. Regarding of the complexity and reliability of the wind-driven generating system, most parts of the powerful wind-driven generators in home can just depend on import, which justifiably makes the cost of the wind-driven generating pretty high. So it's urgently to carry out the research of the speeding device in the wind-driven generating system to make this way of generating electric more economic. This dissertation mainly did following work:Firstly, design the mechanism of the speeding gear box. Using the transmission of one class planet gear and two class cylindrical gear, considering the small scaled of the planet gear's transmission and high gearing ratio of the cylindrical gears, each gearing ratio is: i1 = 5, i2 = 3, i3= 3.5.Based on the given variables in the special work circumstances, parameters of the gear and the structure of the gearing parts was proposed. Through static analysis of the high-speed shaft G, the best structure of the shaft was chosen. And with the software PRO/E, the research carried out the molding and assembling of the gearing parts.Secondly, according to the Rotary Error theory, this paper discusses the influence that the side-crack have on the rotary errors and reveal three kinds of rotary errors(intrinsic errors, assembling errors, other errors)that may come out in the gear drive. What's more, it also figures out the rotary errors of the structure. Based on the results obtained, we know whether its precision distribution meet request, and the way to decrease rotary error was discussed.
