Description

风力发电主轴承
一、技术领域
本发明涉及一种风力发电主轴承，属于风力发电机领域。
二、背景技术
目前，公知的有齿轮箱的风力发电机结构是主轴承置于主轴承座内，主轴承座与机舱底板固定连接，主轴一端与轮毂连接，另一端通过主轴承座与齿轮箱连接，齿轮箱与发电机相连。这种结构上刚性连接，主轴对齿轮箱及发电机的冲击很大，易造成齿轮箱提早损坏，而且维修拆卸起来极不方便。
三、发明内容
本发明的目的有于提供一种可减少对齿轮箱及发电机的冲击，齿轮箱不易提早损坏，维修、拆卸方便的风力发电主轴承。
技术解决方案：本发明包括：主轴承上外圈、主轴承下外圈、止推圆柱滚子、保持架，主轴承内圈，主轴承下外圈内侧设有两列止推圆柱滚子，主轴承内圈的外侧设有单列向心圆柱滚子，圆柱滚子置于保持架上。
主轴承上外圈及主轴承下外圈的侧壁上均设有注油孔。
主轴承上外圈的顶部及主轴承下外圈的底部上设有油封。
主轴承上外圈与主轴承下外圈由内六角螺钉紧固在一起。
主轴承上外圈及主轴承下外圈上设有通孔。
主轴承内圈上设有通孔。
本发明的优点：
1、主轴承的外圈与机舱相连，内圈与轮毂固定，轮毂穿过主轴承与软连接联轴器连接，软连接联轴器齿轮箱连接，这种结构的好处：一是减掉了主轴，二是能大大减小原刚性轴对齿轮箱及发电机的冲击，延长了齿轮箱和发电机的使用寿命，而且很好地实现力的传递，易于维修拆卸。
2、从主轴承的性能看，它是止推主轴承和向心主轴承的组合，外圈内侧两列为止推圆柱滚子，能承受大负荷轴向力。内圈外侧是单列向心圆柱滚子，也能承受较大的径向负荷。两者结合，能很好地适应此种无主轴风力发电机的工况，满足其受力要求。
四、附图说明
图1为本发明结构示意图。
五、具体实施方式
本发明主轴承下外圈11内侧设有上、下两列止推圆柱滚子5和止推圆柱滚子9，主轴承内圈12的外侧设有单列向心圆柱滚子2，圆柱滚子2置于保持架8上，保持架10放置在主轴承下外圈11的内台阶上，止推圆柱滚子9放置在保持架10的滚子位里，主轴承内圈12放在主轴承外圈11的内环里，在主轴承内圈12的外侧放有保持架8，将单列向心圆柱滚子2置于保持架8上，位于保持架8下方的主轴承外圈11的内台阶上放置保持架6，止推圆柱滚子5放置在保持架6的滚子位里，主轴承上外圈1与主轴承下外圈11由内六角螺钉7紧固在一起。
主轴承上外圈1及主轴承下外圈11的侧壁上均设有注油孔3。
主轴承上外圈1的顶部及主轴承下外圈11的底部上设有油封4。
主轴承上外圈1及主轴承下外圈11上设有通孔13。
主轴承内圈12上设有通孔14。
使用本发明时，只需将主轴承外圈通过通孔13与机舱连接，主轴承内圈12通过通孔14与轮毂连接即可。
