行星传动机构作为风电齿轮箱关键部件,因承受无规律的风力作用及强阵风冲击变载荷作用,其工作时的可靠性决定着整台风电齿轮箱传动的可靠性。作为齿轮传动4项要求之一——适当的齿侧间隙是齿轮副正常工作的必要条件,是降低行星轮系传动时冲击、噪声、空程误差,以及提高风电齿轮箱使用寿命的关键。针对一级行星传动结构形式的风电齿轮箱行星齿轮副侧隙偏大问题,从零件制造、装配、测量3个方面对行星轮副侧隙的影响进行了深入分析,确认了装配工艺对行星齿轮副侧隙的影响,通过选配中箱体与主轴承,解决了行星轮齿轮副侧隙偏差问题。 相似文献

The single-rotor wind turbine remains the dominant design for energy production. However, this design requires improvements to overcome some of its limitations. The introduction of the dual rotor system regarded as improvement over the single-rotor system in Korea due to its high efficiency, despite Korea’s low wind quality. Many researchers have attempted to devise different dual rotor machines and assess their power production capabilities under similar wind conditions to those in Korea. Existing power transmissions for dual-rotor wind turbines have issues with the complexity of design, difficulty in manufacturing, high costs and low efficiencies. Therefore, the aim of this study was to design a new power transmission for the dual-rotor wind turbine with an alternative to the bevel-planetary system by using a planetary system. This new method is dependent on the torque ratio and not the gear ratio as in common gear systems. The design and analysis of each part, such as the gears, shafts, bearings and control mechanisms are included in this study. The design is based on the power transmission of a motor vehicle. A prototype of the design is manufactured to verify the proposed method. The experimental results show that the new planetary-type gear box incurs fewer energy losses, has a high efficiency and low manufacturing costs. It is anticipated that the proposed design might be suitable for use with commercial wind turbines. 相似文献

As fears about the effects of global warming increase, the generation of electricity by wind and water power is becoming more popular. As the UK has recently announced a major tranche of funding to aid the establishment of off-shore wind farms, Warrington-based Brevini UK believes that it is well placed to provide rapid and effective customer support throughout Great Britain as its epicyclic planetary gear units are now powering many wind-driven turbines. 相似文献
