具体实施方式
图1中所示为具有纵向轴线11的燃气涡轮发动机10的示范实施例。发动机10包括由通过高压压缩器14表示的核心发动机跟随的风扇区段12。高压压缩机14经由第一轴32由高压涡轮(未示出)驱动。风扇区段12经由第二轴31由核心发动机下游的低压涡轮(未示出)驱动。
无刷式起动器/发电器110(BSG)安装到发动机辅助齿轮箱90并且包括转子轴80,其可操作地连接到示范的功率输出轴100或者可选地连接到可操作地连接到在发动机辅助齿轮箱90内的功率输出轴100的齿轮系101(在图2中示意地示出)。固定地安装在转子轴80上的驱动轴锥齿轮70接合安装到功率输出轴100的功率输出轴锥齿轮72。当无刷式起动器/发电器110以它的起动器模式操作时,它旋转并且通过功率输出轴100驱动发动机,用于起动目的。当无刷式起动器/发电器110以它的发电器模式操作时,它通过功率输出轴100由发动机旋转、驱动并且提供功率,用于产生用于飞行器的电力的目的。
如在图2中示意所示,无刷式起动器/发电器110与辅助齿轮箱90高度集成以便提供低重量和高可靠性的系统。无刷式起动器/发电器110包括放置在壳体116中的环形高速转子112和环形固定定子114。在本文中示出的无刷式起动器/发电器110的示范实施例包括以悬垂设计安装在转子轴80上的转子112,其中转子轴80由布置在辅助齿轮箱90的齿轮箱体122中的轴承120能够旋转地支撑。因而在无刷式起动器/发电器110中不要求轴承,虽然可以结合它们。本文中示出的BSG的示范实施例结合安装在转子轴80上的鼠笼型转子112。
参考图3,BSG具有油冷却系统34,其利用来自辅助齿轮箱90的油30以冷却转子112和定子114,因而允许进一步简化和消除一些维护。利用来自辅助齿轮箱90的油以冷却BSG还允许要求用于气冷有刷式起动器/发电器的起动器/发电器冷却风扇和关联管道/寄生流的消除。BSG油冷却系统34结合干腔冷却,利用干腔冷却在BSG中产生的热由发动机润滑油系统通过对流和通过传导移除到发动机齿轮箱。干腔油冷却系统34的设计包括转子热交换器36和定子热交换器38,其不容许冷却油接触用于BSG的绝缘体40。
不容许冷却油在转子112与定子114之间的空气缝隙42中。干腔设计相对于典型的湿腔设计改进可靠性,在湿腔设计中油被容许接触非金属材料,诸如绝缘体。绝缘体没有退化,因为不存在绕组上的热油的直接冲击。不存在悬浮在油中的腐蚀的绝缘材料,因而防止了油污染(在共用油系统中尤其重要)。油既不喷雾也不与空气混合,因此不存在泡沫,并且不要求空气/油分离器。接触转子的自由油的缺乏还减少了转子的风阻损失。
转子112利用流过BSG转子轴80的中央区域的油通过对流进行冷却。在本文中示出的转子热交换器36的示范实施例包括布置在转子轴80中的柱形内部管道142和围绕内部管道142的环形外部管道144。内部和外部管道142、144通过可为在外部管道144上的帽的柱形交叉件145连接在一起。内部和外部管道142、144作为用于转子热交换器36的轴向流入和流出通道。从辅助齿轮箱90供应的冷却油在布置在转子轴80中的内部管道142的内部流入轴并且通过围绕内部管道142布置的环形外部管道144返回辅助齿轮箱90齿轮箱。
在图3到6中示出的定子热交换器38的示范实施例包括油套150。油套150利用围绕壳体116的有槽管道151形成并且包括轴向延伸的轴向通道152或者提供单程平行油流的沟槽。有槽管道151可由挤制铝材制成。环形进口和出口歧管154、156提供油进口和出口分配并且设计成在油套150的整个周边上供应均匀流。轴向延伸的轴向通道152可以是如图5进一步所示从有槽管道151的内表面153延伸进有槽管道151的轴向延伸沟槽。环形进口和出口歧管154、156可以是如图6和7分别进一步所示,分别从有槽管道151的内表面153延伸进有槽管道151的环形沟槽。在有槽管道151和壳体116之间的O形环密封件136在歧管环形进口和出口歧管154、156的外侧提供以防止油泄漏。
油通过油进口159通过安装在BSG凸缘160上的进口油配件158供应到进口歧管154。油然后通过平行轴向通道152轴向流入出口歧管156并且从出口歧管156通过油出口161偏离油进口159180度地离开。通过提供180度分开的油进口159和油出口161,全部油路径为基本相同的长度,并且油平均分配。油通过安装在BSG凸缘160中的出口油配件162回到辅助齿轮箱90。定子芯还通过到发动机齿轮箱壳体的导热进行冷却。
在图8中示出的定子热交换器38的可选实施例包括带有轴向延伸的轴向通道或者提供单程平行油流的轴向管道172的鼠笼型热交换器170。环形进口和出口管道歧管174、176提供油进口和出口分配并且设计成供应贯穿鼠笼型热交换器170并且特别地通过轴向延伸的轴向管道172的均匀流。
本发明已经以示意方式描述。应当理解所用术语意图为具有描述而不是限制的词语的性质。虽然在本文中已描述被认为是本发明的优选的和示范的实施例,但是本发明的其它修改从本文的示教对本领域技术人员应该显而易见,并且,因此期望属于本发明的真正精神和范围内的所有这些修改在所附权利要求中得到保护。
相应地,期望通过专利得到保护的是在权利要求中限定和区别的发明。
