Description

与复合工作构件一起使用的具有光滑轮廓的金属嵌件
交叉引用的相关申请
本申请要求在2015年2月6日提交的，临时申请号为US62/112681的权益。上述申请的全部内容通过引用并入本文。
技术领域
本发明涉及与泵、压缩机、鼓风机等的旋转工作部件一起使用的金属嵌件。
背景技术
本部分提供不必是现有技术的与本公开相关的背景技术信息。
许多工业和汽车零部件由复合材料制成，相比金属部件来说以减少重量并降低材料成本。另外，复合材料的使用可以导致成型几何形状的改善，进而导致性能的改善，例如，更高的效率和更安静的操作。当采用复合材料作为在流体移动装置或电机中的旋转工作部件时存在问题。特别是，复合旋转工作部件如泵压缩机、风机、风扇和电机的叶轮、转子、风扇叶片、齿轮转子和的其他旋转部件可以包括用于固定目的的金属嵌件。在具体的实例中，复合叶轮包覆模制在金属嵌件上，其固定叶轮到驱动轴上。由于在复合材料中的裂纹，导致的故障已经发生。
本申请公开的内容提供了具有光滑轮廓的金属嵌件，以提供径向和轴向方向的机械锁，使得旋转工作部件的复合材料保持在适当的位置，并且金属嵌件传输驱动到旋转工作部件的复合部分。当复合部分受到机械地和热地负载时，金属嵌件的光滑轮廓减少在复合部分中的应力集中。复合部分和金属嵌件具有不同的热膨胀系数，其可以在加热/冷却时产生热应力。
适用性的进一步区域从本文中提供的描述将变得明显的。在本发明内容中的描述和具体示例仅旨在说明的目的并且不旨在限制本公开的范围。
附图说明
此处所描述的附图仅用于说明选择的实施方式的目的而不是所有可能的实现，并且不旨在限制本公开的范围。
图1是根据本公开原理的具有限定一系列叶片和金属嵌件的复合部分的示例性叶轮的透视图。
图2是本公开原理的金属嵌件的透视图。
图3是为说明的目的除去金属嵌件的示例性叶轮的复合部分的透视图，以及
图4是一种替代的金属嵌件的透视图，其具有截顶的槽纹球体的形状的外表面。
相应的附图标记表示整个附图的全部几个视图中的相应的部件。
具体实施方式
现在通过参考附图更充分描述示例实施例。
提供示例实施例使得本公开将是彻底的，并且将把范围充分传达到本领域技术人员。提出多个具体细节例如具体部件、设备和方法的示例，以提供本公开的实施例的彻底理解。对本领域技术人员将是明显的是，不是必须使用具体细节、可以以很多不同形式来具体实施示例实施例以及也不应该解释为限制本公开的范围。在一些示例实施例中，没有详细描述公知的工艺、公知的设备结构以及公知的技术。
在本文中所使用的术语仅用于描述特定示例实施例的目的，并且不旨在限制本发明。如在此所使用的，单数形式“一”、“一个”和“该”可旨在包括复数形式，除非上下文另有清楚指示。术语“包括”、“包含”、“含有”以及“具有”是包括性的并且因此具体说明所述特征、整体、步骤、操作、元件和/或部件的存在，但不排除一个或多个其它特征、整体、步骤、操作、元件、部件和/或其的组的存在或加入。在本文中描述的方法步骤、工艺以及操作不被解释为以所讨论的或示出的特定顺序必须地需要它们的性能，除非具体确定为性能的顺序。还理解可使用额外的或替代的步骤。
当元件或层被称为在另一元件或层“上”、“接合到”、“连接到”或“联接到”另一元件或层时，其可直接地在另一个元件或层上、接合、连接或联接到另一元件或层，可存在介于中间的元件或层。相比之下，当元件被称为直接在另一元件或层“上”、“直接接合到”、“直接连接到”或“直接联接到”另一元件或层时，不可存在介于中间的元件或层。用于描述元件之间的关系的其它词应该以相似形式来解释(例如，“在…之间”相对于“直接在…之间”、“邻近”相对于“直接邻近”等)。如在本文中所使用的，术语“和/或”包括一个或多个相关联的所列举项的任何和所有组合。
参考图1，示例性旋转工作部件10，以叶轮的形式示出，其包括限定了轮毂14和一系列叶片16的复合部分12，其被包覆模制在根据本公开的原理的金属嵌件18上。复合部分12可以由通常使用的工程塑料或者具有各种已知组合物的其他材料形成。
金属嵌件18可包括槽纹，通常为链状的外表面20和限定内表面24的孔22。内表面24可以是压配合在驱动轴上(未示出)或可任选地包括花键或销用于旋转固定旋转工作部件10在驱动轴上。该槽纹链状的外表面20通常包括较大的外径D1在金属嵌件18的相对端，并且平滑过渡到相对较小的在相对端之间的中间部分的外径D2。链状外表面20包括具有槽纹或凹陷区域26，其具有在槽纹区域26之间变换的光滑轮廓28。槽纹区域26的数量和深度可以基于一个特定的应用而选择。金属嵌件的该链状外表面20提供在轴向方向的机械锁，而槽纹区域26提供在径向方向上的机械锁，使得金属嵌件18输送驱动到复合旋转工作元件。当复合部10受到机械地和热的负载时，金属嵌件18的槽纹链状外表面20的光滑轮廓减少在复合部中的应力集中。
作为替代，如图4所示，金属嵌件118可以设置有截顶球形或大致球体表面120，其具有凹陷槽纹区域126。该截顶球形或球体的外表面120通常包括在金属嵌件118的相对端的更小的外径d1，并且平滑过渡到在相对端之间的中间部分的相对较大的外径d2。金属嵌件118的球形的或球体的外表面120提供在轴向方向上的机械锁，而槽纹区域126提供在径向方向上的机械锁，以便金属嵌件118传输驱动到复合旋转工作元件。槽纹区域126的数量和深度可以依据所需的应用来改变。当复合部10受到机械地和热的负载时，金属嵌件118的球形或球体外表面120的平滑的轮廓减少复合部的应力集中。“截顶”是指球形或球体表面120上设有扁平的或通常扁平端表面128。
已经为了说明和描述的目的提供实施例的上面描述。其不旨在是详尽的或限制本公开。特定实施例的单个元件或特征一般不限于该特定实施例，但是，在适用的情况下，是可互换的并且可在即使没有具体示出或描述的选择的实施例中使用。所述元件或特征还可以以很多方式来变化。这样的变型不视为偏离本公开，并且所有这样的修改旨在被包括在本公开的范围内。
