摘要
风电变桨和偏航驱动器中的齿轮轴采用圆锥滚子轴承,针对该轴承的工程校核计算问题,对比分析和研究了简支梁算法和有限元仿真方法。首先,风电规范文件中对驱动器轴承的强制性要求进行了介绍;然后,分别采用了简支梁算法和Romax有限元仿真两种方法,并通过3个工程案例计算了轴承静载安全系数S_(0)和寿命L_(10h),将校核结果与规范要求进行了对比;最后,基于有限元仿真方法,分析讨论了不同预紧量对轴承安全系数S_(0)、寿命值L_(10h)和齿轮轴最大变形量的影响。研究结果显示:由于不满足强制性要求的规定,简化的简支梁算法不适用于驱动器齿轮轴轴承的校核,采用有限元方法的适用性更好;综合考虑安全系数值、轴承寿命值和齿轮轴变形量3个因素,建议轴承的预紧量在0~0.35范围内选取。
Aiming at the problem of engineering checking calculation of tapered roller bearing used for pitch and yaw driver gear shaft of wind power,the simple beam algorithm and finite element simulation method were compared and analyzed.Firstly,the compulsory requirements of driver bearing in the wind power specification document were briefly introduced.And two methods of bearing checking,namely simple beam algorithm and finite element simulation were adopted.And the static load safety factor S_(0) and life L_(10h) of the bearing are calculated through three engineering cases.The checking results were compared with the compulsory requirements.Finally,based on the finite element simulation method,the influences of preloaded quantity on the bearing safety factor,life and maximum shaft deformation were discussed.The results show that the simplified simply supported beam algorithm is not suitable for the verification of the drive gear shaft bearing,because it does not meet the mandatory requirements.The applicability of the finite element method is better.Considering the three factors of safety factor value,bearing life value and gear shaft deformation,it is recommended that the preload of the bearing is selected in the range of 0~0.35.
