洛轴 / 风力发电专用轴承

风力发电专用轴承

主轴轴承

位于叶轮主轴,工作负荷高,并要求能够补偿主轴的变形。因此,该轴承应具有良好的调心性能、较高的负荷容量,以及较长的使用寿命。一般采用通过优化设计的调心滚子轴承。

偏航轴承

安装于风力发电机组机舱底座总成的偏航 机构,用于准确适时地调整风机的迎风角度,并将雷电传导至地面,承受负荷为:径向负荷、轴向负荷和倾覆力矩。要求密封性能好、可靠性高、运转灵活及平稳性好、表面防腐、寿命超过20年等。该类轴承一般采用特大型四点接触球或交叉圆柱滚子转盘轴承。

变桨轴承

位于叶片的变桨系统总成,用于调整叶片的迎风方向,主要承受径向负荷、轴向负荷和倾覆力矩。要求该轴承具有良好的密封性能、高可靠性、表面防腐,并且运转灵活、寿命超过20年等。该类轴承一般采用特大型四点接触球或双排球转盘轴承。

此试验机为洛阳LYC轴承有限公司独立研发,拥有自主知识产权,可完全模拟变桨轴承在风机上的安装及运行状态,可对变桨轴承的启动力矩、密封性能、平衡性及耐久性等性能进行测试,满足了用户对风电轴承高可靠性的个性化需求。
