Description

齿轮结构、齿轮箱及风力涡轮机
技术领域
本实用新型涉及齿轮结构、齿轮箱及风力涡轮机。 
背景技术
在行星齿轮结构的组装过程中，重要的是确保对行星齿轮轴承的适当调整。如果轴承设有过多的预载荷，这些轴承可能会过早地失效。另一方面，轴承中过大的端隙使轴承具有过大的内部间隙，并且齿轮的轴线会倾斜而且与太阳轮和环齿轮错位。这样在齿轮中产生较大的噪音和摩擦。螺纹元件、垫片和隔离件是典型的方法用来通过轴向调整来提供刚性预载荷。这种技术需要极大的专注度和精度，以避免过度占用内部间隙，这样的情况可能在安装过程中通过轴承过载造成，或在操作过程中由于热膨胀造成。在这里，精密研磨的垫片通常是优选于螺纹元件的，因为螺旋线会导致错位。因为垫片必须能够以1-2微米或更高精度来间隔轴承，所以垫片应该制造成其平行度公差与轴承的平行度公差相等。 
实用新型内容
根据本实用新型的第一实施方式，一种用于行星齿轮箱的齿轮结构包括行星齿轮架、行星齿轮销、行星齿轮、位于行星齿轮销和行星齿轮之间的轴承装置、通过一个或多个螺栓固定到行星齿轮架的限位器以及位于限位器和行星齿轮销之间的一个或多个垫片，所述轴承装置包括轴承环。行星齿轮销是空心的，并且和轴承环的内侧表面以及入口流体连通。这意味着被驱使经过入口和空心行星齿轮销的流体给轴承环施加径向力，减少了轴承环和行星齿轮销之间的接触摩擦，并且允许行星齿轮销的轴向位置被调整从而给轴承装 置提供正确的预加载。这意味着所述轴承能被预设置，在原位置使用液压致动器和油喷。 
优选地，当轴承装置经过使用被磨损时，行星齿轮销的轴向位置可以被重新调整，从而给轴承装置提供正确的预加载。 
优选地，选择一个或多个隔离件的数量和厚度，用于锁定具有正确预加载的轴承装置的轴向位置。 
根据另一个方面，本实用新型包括一种风力涡轮机，该风力涡轮机包括在前面段落中描述的齿轮结构。 
根据另一个方面，本实用新型包括一种具有在前面段落中描述的齿轮结构的齿轮箱，该齿轮箱还包括具有检查盖的前壳体。检查盖的位置被构造为能移开，从而允许接近限位器。这意味着被驱使经过入口和空心行星齿轮销的流体给轴承环施加径向力，减少了轴承环和行星齿轮销之间的接触摩擦，并且允许行星齿轮销的轴向位置被重新调整从而给轴承装置提供正确的预加载。 
优选地，选择一个或多个隔离件的数量和厚度，用于锁定具有正确预加载的轴承装置的轴向位置。 
根据另一个方面，本实用新型还包括一种风力涡轮机，该风力涡轮机包括在前面段落中描述的齿轮箱。 
根据另一个方面，本实用新型包括一种调整行星齿轮箱的齿轮结构的轴承布置的预加载的方法，所述齿轮结构包括行星齿轮架、行星齿轮销、行星齿轮、位于行星齿轮销和行星齿轮之间的轴承装置、通过一个或多个螺栓固定到行星齿轮架的限位器以及位于限位器和行星齿轮销之间的一个或多个垫片，所述轴承装置包括轴承环；其中所述行星齿轮销是空心的，并且和轴承环的内侧表面以及入口流体连通；所述方法包括以下步骤：移走所述螺栓和一个或多个垫片；将液压致动器连接到入口；驱使流体通过入口和空心行星齿轮销，给轴承环施加径向力，减少轴承环和行星齿轮销之间的接触摩擦；调整行星齿轮销的轴向位置从而给轴承装置提供正确的预加载；以及固定所述螺栓和所述一个或多个垫片。 
优选地，当轴承装置经过使用被磨损时，调整行星齿轮销的轴向位置的步骤包括重新调整轴向位置，从而给轴承装置提供正确的预加载。 
优选地，该方法包括以下步骤：选择一个或多个隔离件的数量和厚度，用于锁定具有正确预加载的轴承装置的轴向位置。 
附图说明
现在将参考附图1-4描述本实用新型。 
图1示出了齿轮结构的示意图； 
图2示出了齿轮结构的横截面视图； 
图3示出了齿轮箱的示意图； 
图4示出了离岸风力涡轮机的外视图。 
具体实施方式
图1示出了行星齿轮结构100，其具有行星齿轮架102、行星齿轮销104、轴承装置106和行星齿轮108。行星齿轮结构100是常规设计；行星齿轮销104被安装在行星齿轮架102上并具有轴承装置106，该轴承装置支撑行星齿轮108。 
行星齿轮销104通过限位器装置110被固定就位，该限位器装置与行星齿轮销104相关并附接到行星齿轮架102。例如，限位器装置110可以通过限位器装置110和行星齿轮销104上的螺纹布置与行星齿轮销104相关；限位销可以通过螺栓114固定在行星齿轮架102上。行星齿轮销104相对于行星齿轮架102和轴承装置106的轴向位置由位于限位器装置110和行星齿轮架102之间的隔离件装置112确定。 
行星齿轮销104的轴向位置对轴承装置106预加载，正确的预加载由隔离件装置112的轴向厚度确定。隔离件装置112通常是一个或多个垫片，其被定位在限位器装置110和行星齿轮架之间，用于保证轴承装置106的正确预加载。 
隔离件装置112预先选择成具有能够对轴承装置106正确地预加载的轴向长度。 
在行星齿轮销的初始安装期间，利用常规的低温装配。 
现在参见图2，行星齿轮销104是空心的并且通过管道302与轴承环306的内侧表面流体连通。一个或多个垫片112设置在限位帽110和行星齿轮销104之间，并通过螺栓114夹在限位帽110和行星齿轮销104之间。垫片112的数量可以增加或减少以通过机械手段调整轴承环的位置。通过该方式，存在的垫片112的数量能够用于通过调整限位帽110和行星齿轮销104之间的间隙来调整预加载。 
为了最终装配，液压致动器，带有油喷配件和油喷的空心螺栓304被用于调整行星齿轮销104的位置，从而调整轴承106的位置。当流体被泵送到入口304中时，流体沿着轴承环306和行星齿轮销104之间的环形沟槽被驱动，并对轴承环306施加径向力，因此减少了轴承环306和行星齿轮销104之间的接触摩擦。这能用于调整轴承环306的位置，所以只需要少量力来轴向运动轴承环306。 
行星齿轮108能够在这种操作期间转动，以保证正确的预加载，在该阶段预加载由液压压力确定。一旦行星齿轮销104和轴承装置106就位，则油喷被移走，液压压力被释放，紧固垫圈110和螺栓114被装配。垫片112这里用在行星齿轮销104的端部和紧固垫圈110之间。 
现在参见图3，示出了具有行星齿轮结构100和壳体202的部分齿轮箱200。壳体202具有前表面204，在大致圆形的前表面204的一段中径向地布置有孔206。孔206被布置为与限位器装置110对准。当轴承装置106磨损时，由行星齿轮销104施加的预加载变得不正确。限位器装置110与行星齿轮架102断开连接，并从行星齿轮销104上移走，使得隔离件装置112也同样移走。行星齿轮销104的轴向位置可以被重新调整，从而给轴承装置106提供正确的预加载，可以安装具有合适轴向尺寸的替换隔离件装置112，并且限位器装置可以重新附接到行星齿轮架102。然后可以将检查盖(未示出)放置 在孔206上。 
为了在工作期间维护轴承106的重新定位和调整，在前壳体202中的检查盖被移走，使行星齿轮架102转动直到对准该行星齿轮架。装配液压致动器，带有油喷配件和油喷的空心螺栓被用于调整行星齿轮销104的位置，从而调整轴承106的位置。再次由液压压力确定预加载。该设备可以暂时移走，从而转动行星齿轮架103以及因此转动轴承106。一旦行星齿轮销104和轴承106就位，则油喷被移走，液压压力被释放，紧固垫圈110和螺栓114被装配。垫片112这里用在行星齿轮销104的端部和紧固垫圈110之间。 
本实用新型的优点包括： 
可以利用钻孔的行星齿轮销等为轴承提供润滑； 
最小的零件数量； 
任何零件都不用特定的加工； 
轴承能被预设置，在原位置使用液压致动器和油喷； 
提供正确设计的前盖接近孔，液压致动器和油喷能够装配在涡轮机内，并且轴承在其寿命内可以重新定位； 
既能够在首次组装时设置间隙，又能够在运行期间进行调整。 
图4是风力涡轮机的一个示例的透视图。虽然所示的是离岸风力涡轮机，但应当明白以下描述可以适用于其他类型的风力涡轮机。风力涡轮机402包括安装到毂406的转子叶片404，该毂由塔架410上的机舱408支撑。风引起转子叶片404和毂106绕主轴线转动。这个转动能量被传递到容置在机舱408内的齿轮箱。
