Abstract

本发明公开一种行星齿轮架组件。一种齿轮箱组件，包括至少一个行星齿轮组，所述行星齿轮组包括一个或多个齿圈、一个或多个太阳齿轮和行星齿轮架。行星齿轮架支承两组周向隔开的行星齿轮轴承、销和行星齿轮。轴承、销和行星齿轮能够相对于齿轮架支承盘在角度方向上自调节，由此行星齿轮的转动轴线可以保持垂直于或者斜交于行星齿轮架的平面。

Description

行星齿轮架组件
技术领域
本发明涉及一种行星齿轮架组件。
背景技术
传统的风力涡轮机齿轮箱使用一个或多个行星齿轮组，以将转子提供的动力的转矩降低、转速上升。在高动力应用中使用行星齿轮组的一个缺点是行星齿轮和轴承必须承受相当大的负载。目前对这一问题的解决方案是增加齿轮组中行星轮的数量，但是这样会限制齿轮组能够实现的传动比。
美国专利7090465(图1)提供了一种方法，其通过使用双侧齿轮架(或转向架)以将额外的行星轮加入系统。这样的优点是在允许实现更高的传动比的同时降低了行星齿轮和轴承上的负载。但是，该设计的缺点是，每对相对的行星齿轮47需要共用的销44。因此，齿轮架两侧的行星齿轮不能完全独立，并且一个行星齿轮上的负载会影响使用共用的销的齿轮，在销是柔性的应用情况下这一点是特别重要的。
发明内容
本发明公开一种设计，其中销以及随后的齿轮被偏置，确保了系统中的每个销与其他销上的负载无关。
根据第一方面，本发明提供一种行星齿轮组，其包括一个或多个齿圈、一个或多个太阳齿轮、以及行星齿轮架，所述行星齿轮架支承两组周向隔开的行星齿轮轴承、销和行星齿轮，所述轴承、销和行星齿轮能够相对于齿轮架支承盘在角度方向上自调节，使得所述行星齿轮的转动轴线能够保持垂直于或者斜交于所述行星齿轮架的平面。
优选地，每组行星齿轮定位在安装到或者与行星齿轮架一体的中央盘的相对侧。
优选地，两组行星销、轴承和齿轮在周向上偏置大于0度的角度。
优选地，所述销承载单个行星齿轮。
优选地，所述销包括柔性销。
还描述了包括至少一个如权利要求1所述的行星齿轮组的齿轮箱组件。
还描述了包括如权利要求6所述的齿轮箱组件的风力涡轮机。
附图说明
图1是US7090465所公开的现有技术系统的示意图；
图2是本发明的示意图，其包括六个行星齿轮，齿轮架的每侧具有三个行星齿轮；
图3是本发明的三维示图，示出行星齿轮相对于彼此的一种可能的位置；
图4表示根据本发明的各种实施方式的风力涡轮机的示意图。
具体实施方式
图2示出椭圆或行星齿轮组，其包括齿圈1、太阳齿轮2、行星齿轮架8、第一行星齿轮组4和第二行星齿轮组3。第一行星齿轮组4在轴向上位于第二行星齿轮组3的前面、第一行星齿轮组4定位在中央盘齿轮架8的一侧上(虚线所示的位置)，第二行星齿轮组3定位在中央盘齿轮架8的另一侧上(虚线表示)。两组行星齿轮均与齿圈1和太阳齿轮2啮合。显示了分别支承第一行星齿轮组4和第二行星齿轮组3的行星销9和10的位置。两组行星齿轮以及相关的销和轴承彼此周向偏置。这在图2中由经过第一行星齿轮组4之一的中心和太阳齿轮2的中心的线11和经过第二行星齿轮组3之一的中心和太阳齿轮2的中心的线12之间的角度5表示。该角度可以是大于0度的任何角度。
行星齿轮架支承两组周向隔开的行星齿轮轴承、销和行星齿轮的这种布置使得行星齿轮的转动轴线能够保持垂直于或者斜交于行星齿轮架的平面，继而允许轴承、销和齿轮相对于齿轮架支承盘在角度方向上自调节。
每个销9、10承载单个行星齿轮。销可以是柔性销。
图3更具体地示出本发明的一种简单的实施方式，为了清楚，图3仅集中于行星齿轮架而未显示太阳齿轮和齿圈。动力经齿轮架前方的连接器7输入至行星齿轮架6。两组行星齿轮3和4、销9和10以及相关的轴承(未示出)以偏置的方式经中央盘形齿轮架8安装至齿轮架6。
行星齿轮架支承两组周向间隔的行星齿轮轴承、销和行星齿轮，轴承、销和行星齿轮能够相对于齿轮架支承盘沿角度方向自调节。行星齿轮的转动轴线可以保持垂直于行星齿轮架的平面，或者与该平面斜交。
附图所示的实施方式集中于使用两组每组三个行星齿轮的情况。但是，在系统中可以使用任何数量的行星轮，该设计使得可以根据需要在齿轮架的两侧使用不同数量的行星轮。
上面描述的椭圆或行星齿轮组可用于齿轮箱组件。齿轮箱组件可用于图4所示的风力涡轮机。除了齿轮箱组件18，风力涡轮机包括机舱13(也可称为涡轮机壳体)、支承柱14、转子15、转子轴16和发电机20。风力涡轮机10设置为将风能转换成电能。风力涡轮机10可离岸地安装或者可以安装在内陆。
