Abstract

本发明涉及一种具有传动装置、穿通管(103)和固定机构(101)的设施；其中，穿通管(103)借助固定机构(101)固定在传动装置中。固定机构(101)由非电导体构成。

Description

绝缘的穿通管
技术领域
本发明涉及根据权利要求1的前序部分的设施。
背景技术
在风力发电机组中表现出整合式驱动系的趋势。对于整合式驱动系，传动装置和发电机形成一个结构单元。这会导致杂散电流的问题。杂散电流可能呈高频交流电流或者低频直流电流或低频交流电流的形式出现。存在由于电压浪涌而发生损坏齿部和滚动轴承的风险。
必须采取适当的绝缘措施，以便避免杂散电流引起的间接损坏。然而，在中速运转的驱动系中，要在传动装置与发电机之间传递的转矩相对较高。同时，由于在传动装置与发电机之间的驱动系的整合式结构形式而缺少可用的结构空间。这使得难以足够大地设定传递转矩的构件的尺寸。这尤其涉及传递转矩的构件的电绝缘。
发明内容
本发明的任务在于，提供一种相对于由现有技术已知的传动装置改善了的解决方案。特别是，应避免由于杂散电流而在整合式驱动系中可能发生的损坏。
该任务通过根据权利要求1的设施来解决。优选的改进方案包括在从属权利要求中。
特别是，传动装置可以是用于风力发电机组的传动装置。穿通管，也称为桨距管(Pitch Tube)，是一种用于使例如电或液压的供应线路穿过传动装置的管。穿通管的特征在于，它穿过传动装置或传动装置壳体并且其通口布置在传动装置或传动装置的壳体之外。优选地，穿通管相对于传动装置的壳体密闭从而润滑剂不能通过。
穿通管借助固定机构固定在传动装置中，即传动装置的至少一个部件中。穿通管通常设计为旋转对称的。优选地，固定机构相应地也是旋转对称的。
本发明基于如下认识，即由于穿通管完全穿过传动装置，则穿通管是杂散电流的主要传递者。因此，根据本发明，固定机构由非电导体构成，例如由聚酰胺构成。因此，该固定机构使穿通管与传动装置的如下部件彼此绝缘，穿通管借助固定机构固定在该部件中。由此消除了泄漏电流的主要产生原因。本发明有效地防止了来自发电机的泄漏电流经由穿通管被导入传动装置中。根据本发明的绝缘特别适合于整合式驱动系，因为它需要很少的结构空间。
优选地，穿通管被改进成不能相对于固定机构轴向运动，即不能在转动轴线的方向上运动，例如不能在其中借助固定机构固定穿通管的那个部件的转动轴线的方向上运动。优选地，固定机构相应地以不能轴向运动的方式固定在传动装置中或上述部件中。
在优选的改进方案中，传动装置的在其中借助固定机构固定穿通管的那个部件是轴，尤其是空心轴，或者是以能转动的方式受支承的行星架。根据改进方案，固定机构使穿通管相对于轴或行星架电绝缘。
在更优选的改进方案中，固定机构具有贯穿的孔。孔在中心取向，即，其中轴线与穿通管的中轴线一致。特别是，穿通管和孔可以是旋转对称的。在这种情况下，穿通管的对称轴线和孔的对称轴线一致。穿通管延伸穿过孔并且在那里设有固定机构。
在一个优选的改进方案中，固定机构沿着其径向外边缘与传动装置的在其中固定有穿通管的那个部件或者与轴或行星架相接。
优选地，固定机构被改进成使得其具有径向取向的盘的基础形状。主体的基础形状是原始主体的形状，通过消除各个区域(例如通过加入留空部)和/或通过添加各个区域而从该原始主体形成主体。
在一个优选的改进方案中，为了使穿通管相对于传动装置的壳体流体密封地密闭，设置有密封件。密封件与固定机构轴向间隔开。特别是，密封件和固定机构可以布置在传动装置壳体的相对置的壁上。穿通管能在密封件中或相对于密封件轴向移动。由此，确保了补偿由温度波动所引起的穿通管长度变化。
附图说明
本发明的实施例在附图中示出。相同的附图标记在此表示相同或功能相同的特性。其中：
图1示出由聚酰胺构成的固定机构；和
图2示出由聚酰胺构成的密封件；
具体实施方式
图1中所示的固定机构101用于在驱动侧将穿通管103固定在行星架105中。通过固定机构101确定了穿通管103的径向定位。
固定机构101具有凸起107，这些凸起径向向内延伸并且嵌入到穿通管103的相应的留空部109中。由此，实现了在固定机构101与穿通管103之间的抗相对转动的连接。此外，固定机构具有槽111，该槽在周向方向上围绕穿通管103地延伸并且向内敞开。穿通管103具有相应的槽111。两个槽111和113以它们的开口指向彼此，从而它们可以共同地容纳定固圈115。通过定固圈115实现在固定机构101与穿通管103之间的轴向固定。
固定机构101刚性地固定在行星架105中，即固定机构101与行星架105之间的固定不允许固定机构101与行星架105之间的任何相对运动。
固定机构101由电绝缘体构成。在这里描述的实施例中，聚酰胺被用作电绝缘体。
如在图2中所示，在发电机侧设置有迷宫式密封件201，其也由绝缘体构成，此处是由聚酰胺构成。迷宫式密封件201一方面密闭穿通管103以防传动装置油流出并且另一方面确保电绝缘。
