Description

风力发电偏航轴承
技术领域
本实用新型涉及一种滚动轴承，特别是涉及一种风力发电机中用于偏航的轴承。
背景技术
在风力发电过程中，风力发电机组的风轮应该始终处于迎风状态。即当风向发生变化时，风力发电机组的风轮也同时发生变化。因此，发电机组需要通过由驱动装置及偏航轴承组成的***来实现机舱和塔架的相对转动，偏航轴承的轴承内外圈分别与风力发电机组的机舱和塔架连接。这样使得发电机组的风轮能够准确定位，始终处于迎风状态，充分利用风能进行发电。
现有的轴承不是很紧凑，在风力发电机中安装偏航轴承不方便。有些风力发电偏航轴承的外部处理不够，不那么的经久耐用。
发明内容
本实用新型需要解决的技术问题是提供一种操作方便，结构简单、紧凑，定位准确的风力发电偏航轴承。
为解决上述技术问题，本实用新型的风力发电偏航轴承由外圈、内圈、滚动体和保持架组成，外圈通过钢球与内圈连接，所述的钢球与内圈的连接处横向设置有堵塞，堵塞的另一端固定在内圈的内壁上，堵塞的轴向开有通孔，通孔中***销；至少一组钢球与内圈的连接处横向设置有油嘴；外圈上有轮齿。
采用这样的结构后，整个轴承的结构紧凑，安装便捷，操作方便，在发电机偏航结构中能起到很好的效果。轴承面上热喷涂纯锌，然后再涂上环氧树脂漆。在经过这些外部处理之后，轴承就更加的经久耐用。
附图说明
下面结合附图和具体实施方式对本实用新型作进一步详细的说明。
图1是本实用新型风力发电偏航轴承的剖视图。
具体实施方式
图1所示的风力发电偏航装置由外圈、内圈、滚动体和保持架组成，外圈通过钢球与内圈连接，所述的钢球与内圈6的连接处横向设置有堵塞8，堵塞8的另一端固定在内圈6的内壁上，堵塞8的轴向开有通孔，通孔中***销7，销7主要起到固定的作用。至少一组钢球3与内圈6的连接处横向设置有油嘴5，可以通过油嘴5对钢球组添加润滑油，外圈1上有轮齿4。每组钢球3有两个，成轴向分布，两者之间是连通的，这样可以提高轴承的抗冲击性能。外圈1与内圈6的连接处安有密封条2，主要是防止润滑油外泄。外圈1上开有螺栓孔，方便整个轴承固定在风力发电机的塔架上。
轴承面上热喷涂纯锌，然后再涂上环氧树脂漆，这样的处理可以使得整个轴承更加的耐用。
