Description

在风力发电装置的转子和发电机之间的传动系统
技术领域
该发明涉及一种转子和风力发电机之间的传动系统，其中该传动系统中包含一个行星齿轮机构；该齿轮机构具有行星齿轮托架，该托架相对于壳体部件通过至少一个滚动轴承可转动地支承，其中，该滚动轴承含有至少一个内环和至少一个外环，并且滚动体设置在上述内外环之间。
背景技术
风力发电装置需要传动系统，使由轮毂上的转子产生并导入的转矩传递至发电机转动，以实现风能到电能的转化。对此使用行星齿轮机构进行转子转动的转化。上述风力发电装置中的行星轮在DE 10 2012 214 023 B3中给出。
对于所述应用、即风力发电设备中行星齿轮机构的行星齿轮拖架的轴承，大多采用满滚子圆柱滚子轴承(或者满滚子圆锥滚子轴承)。选择满滚子轴承的主要理由即在于这种轴承不需要轴承保持架，并且因此相对具有保持架的轴承更加廉价，这尤其在大型设备方面是有利的。
但是不利的是，在滚动体之间存在积油(Anschmierung)的风险。因此，滚动体、(如果有必要的话)轴承环都要进行发蓝处理。这一点对节约成本又有负面影响。
满滚子轴承的另一个缺点在于不能实现自保持，也就是在轴承安装时，轴承中的单个零件只能被束紧；而在拆卸轴或者内圈时零件会相互散落。
满滚子轴承中所能达到的高承载量在大多数情况中并不非常重要。
发明内容
本发明的所要解决的技术问题在于，提供一种此类型的具有行星齿轮机构的传动系统，其中可以更廉价地实现轴承，而且还提供轴承的充足的稳定性。此外，相较于使用满滚子轴承应该以更简单的方式装配和拆卸所述轴承。
所述技术问题通过本发明这样解决：在两个相邻的滚动体之间各设置一个间隔元件，该间隔元件具有用于两个滚动体的运行面，其中，在轴承环之间的区域除了间隔元件没有其他的保持架元件。
该间隔元件应优先选择塑料制品。该塑料材料优选是聚醚醚酮(PEEK)。间隔元件优选借助注塑成型进行制造。
该滚动体最好具备硬化且磨光的表面，但是该表面不经历发蓝处理。
该间隔元件可以布置在轴承环之间，使间隔元件径向内端沿径向位于分度圆下方，其径向外端沿径向位于分度圆上方。这有利于轴承产生一个自保持效果。
该间隔元件可以通过连接元件、尤其是绳索或者缆线相互连接。因此，在轴承部件部分拆卸时，轴承部件的连接可以得到改善。
该滚动轴承优选设计为圆柱滚子轴承。
此处同样也可以选择圆锥滚子轴承。在这种情况下，可以通过两个轴向间隔开的圆锥滚子轴承相互轴向预紧，以实现行星齿轮托架的轴承。
根据发明的方案放弃使用昂贵的发蓝处理的滚动体(滚子)。取而代之，使用一种由合适材料制成的保护架间隔件(间隔垫片)用于保持和引导滚动体，其中聚醚醚酮(PEEK)材料已被证实极其适用。因此，不存在积油的风险是本发明的优势所在。
进一步的成本节约可以采取以下方法实现，即部分放弃昂贵滚子子，取而代之使用经济性更好的间隔件(塑料间隙垫片)。
本发明的另一个优点在于：在根据发明的行星齿轮拖架的轴承的结构中，可以通过间隔件(即间隙垫片)的合理设计，实现轴承的自保持。由此，操作方法以及必要时轴承控制和装配变得有利并且简单。
附图说明
附图展示了本发明的实施案例。在附图中：
图1示出作为风力发电装置的传动系统的组件的行星齿轮机构的部分的径向截面示意图，以及
图2示出滚动轴承的两个相邻的滚动体(通过此滚动轴承实现行星齿轮机构的行星齿轮托架的轴承)
具体实施方式
在图1中示意性地描述了行星齿轮机构1的一部分，该行星齿轮机构1实现了传动系统中风力发电装置转子(未显示)到发电机(未显示)之间的转矩转化。行星齿轮机构1中含有一个行星齿轮托架2，该托架2通过一个滚动轴承4与壳体部件3连接。以此实现行星齿轮托架2围绕轴线a的旋转。
行星齿轮机构的结构众所周知，在此不作细致描述。有关这部分的详细分析可以参考文献DE 10 2012 214 023 B3。
滚动轴承4的结构在图2中显现，其中包含两个相邻的滚动体5和一个间隔元件6。该结构中每两个滚动体之间含有一个间隔元件6。
该间隔元件6由塑料制成，类似于滚动轴承中的间隙垫片。此处引用了申请人的申请材料DE 10 2011 087 864 A1作为详细参考，其显示了相似类型的保持架部段。
每个间隔元件6具有侧向的运行面7、8，该运行面的形状与滚动体5形状相适应。如同图2中展示的那样：间隔元件6的径向外端沿径向往外伸展到分度圆直径DT上方；与此同时，间隔元件6的径向内端沿径向往下延伸至分度圆下方。因此，在拆卸轴承外环或者内环时，可以得到一个自保持的单元。
