Abstract
风力发电机用分块式主轴承结构，属于轴承技术领域。为了解决风力发电机塔上维护困难的问题，大幅降低检修经济成本。该分块式主轴承结构主要由径向主轴，锥形块，瓦块，弹性阻尼器，弹性密封圈，上端盖，径向连接轴，下底座等等组成。目前，传统的风电机组主轴通常采用滚动轴承作为支撑件，但滚动轴承通常不能达到计算寿命，且高故障率提升了拆卸更换的成本。本发明采用了“以滑代滚”的优化思路，并将滑动轴承和多层式弹性阻尼器相结合。其中滑动轴承的承载力大，使用寿命长；多弹性阻尼结构器中有挤压板，柱塞，密封圈等，起到减振吸能的作用。相对于传统的风力发电机主轴承结构，本发明所述的分块式主轴承结构更容易实现工程推广。
