Description

两用螺纹插入件/压缩限制器
技术领域
本公开涉及一种用于复合盖板的压缩限制器，该压缩限制器包括用于容纳千斤顶螺钉以便于移除盖板的内螺纹。
背景技术
本部分提供与本公开相关的但不一定是现有技术的背景信息。
如图4所示，目前的复合底壳/盖板组件110在每个螺栓孔114处具有金属压缩限制器112，以便容纳安装螺栓116。如图5所示，底壳/盖板组件110还包括金属螺纹插入件116，该金属螺纹插入件116与千斤顶螺钉118配合使用，帮助破坏密封剂结合并分离底壳/盖板组件110。
发明内容
本部分提供了本公开的总体概述，并且不是其全部范围或其所有特征的全面性公开。
一种盖板构件包括由复合材料制成并且包括安装凸缘的主体构件。多个压缩限制器设置在安装凸缘中，该压缩限制器具有预定厚度并在其内具有内螺纹孔。双重功能压缩限制器无需采用单独的螺纹插入件。借助于本公开内容，每个螺栓位置为千斤顶螺钉提供了可能的位置。
根据在此提供的描述，其他应用领域将变得显而易见。此发明内容中的描述和具体示例仅用于说明的目的，并不旨在限制本公开的范围。
附图说明
在此描述的附图仅用于说明选定实施例，而不是所有可能的实施方式，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复合盖板和压缩限制器/千斤顶螺钉插入件的发动机的剖视图，其中该压缩限制器/千斤顶螺钉插入件容纳安装螺钉；
图2是根据本公开原理的具有复合盖板和压缩限制器/千斤顶螺钉插入件的发动机的剖视图，其中该压缩限制器/千斤顶螺钉插入件容纳千斤顶螺钉；
图3是根据本公开原理的压缩限制器/千斤顶螺钉插入件的立体图；
图4是具有传统复合盖板以及压缩限制器和单独千斤顶螺钉插入件的剖视图，其中安装螺钉通过压缩限制器插入；以及
图5是发动机的剖视图，其中该发动机具有传统复合盖板以及容纳千斤顶螺钉以移除复合盖板的压缩限制器和单独千斤顶螺钉插入件。
在附图的多个视图中，相应的附图标记表示相应的部分。
具体实施方式
现在将参照附图更全面地描述示例性实施例。
之所以提供这些示例性实施例是为了使本公开内容变得详尽，并且将范围充分地传达给本领域的技术人员。为了提供对本公开的实施例的透彻理解，阐述了许多具体细节，诸如具体部件、装置和方法的示例。对于本领域技术人员来说将是显而易见的是，不需要采用具体细节，示例性实施例可以以许多不同的形式来体现，并且都不应该被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过程、公知的装置结构以及公知的技术。
在此使用的术语仅用于描述特定示例性实施例的目的，并不旨在具备限制性。如本文所用，除非上下文另外明确指出，否则单数形式“一个(a)”、“一个(an)”和“该”也旨在包括其复数形式。术语“包括(comprises)”、“包括(comprising)”、“包括(including)”和“具有”是包含的，因此指明了所陈述的特征、整体、步骤、操作、元件和/或组件的存在，但不排除存在有或添加了一个或多个其他特征、整体、步骤、操作、元件、组件和/或其组合。在此描述的方法步骤、过程和操作不应被解释为必须要求它们以所讨论或示出的特定顺序执行，除非具体明确了执行顺序。还应该理解的是，可以采用附加的或替代的步骤。
当元件或层被称为“位于”、“接合到”、“连接到”或“联接到”另一元件或层上时，它可以直接位于、接合到、连接到或联接到另一元件或层上，或者可以存在有中间元件或层。相反，当元件被称为“直接位于”、“直接接合到”、“直接连接到”或“直接联接到”另一元件或层时，可能不存在有中间元件或层。对于用于描述元件之间关系的其他词语，应该以类似方式加以解释(例如，“在...之间”与“直接在...之间”、“相邻”与“直接相邻”等)。如本文所用，术语“和/或”包括一种或多种关联的所列项目的任何和所有的组合。
参考图1和图2，示出了包括发动机结构12和底壳/盖板组件14的发动机组件10。底壳/盖板组件包括具有安装凸缘18的复合主体16。多个压缩限制器20安装在安装凸缘18内，并且与发动机结构12中的螺纹安装孔22对齐。如图1所示，安装螺钉24穿过压缩限制器20插入并插入到螺纹安装孔22中，以将底壳/盖板组件14固定到发动机结构12。如本领域所公知的，螺钉保持器26可以可选地设置在压缩限制器20内，并且能够在将底壳/盖板组件10组装到发动机结构12上之前将安装螺栓24固定在压缩限制器20内。
如图3所示的压缩限制器20包括主体30，主体30可以由金属材料制成并且具有带内螺纹孔32的预定厚度。主体30可以包括具有多个平坦表面的多边形外表面34以及径向向外延伸的凸缘部分36。压缩限制器20可以压入配合、结合、包覆成型或以其他方式保持在安装凸缘18中的对应孔内。安装螺栓24的螺栓直径小于压缩限制器20的内螺纹孔32的内径。
如图2所示，安装螺栓24和可选的螺钉保持器26可以从螺纹安装孔22和压缩限制器20上移除。然后，可以将较大直径的千斤顶螺钉40螺纹地插入到压缩限制器20的内螺纹孔32中，由此使得千斤顶螺钉40的一端接合发动机结构12围绕螺纹安装孔22的表面，并且使得压缩限制器20和底壳/盖板组件14远离发动机机构12提升，从而破坏底壳/盖板组件14与发动机结构12之间的密封剂结合。
两用螺纹压缩限制器20将多个功能集成在一个在复合油底壳及盖板组件中使用的部件内。压缩限制器20通过提供多个撬动点来提高部件的可用性，并且通过消除单独的螺纹插入件来降低成本。压缩限制器20改善了密封周边周围的部件包装以及发动机结构周围的凸台的部件包装。尽管已经结合了发动机组件10来公开本发明的两用压缩限制器20，但应当理解的是，压缩限制器20可以用于发动机、变速器和其他采用了复合材料的工业机械。
出于说明和描述的目的，已经提供了对实施例的上述描述。此描述的目的并不是穷举性的或者对公开内容造成限制。即使没有具体地示出或描述，特定实施例的各个元件或特征通常并不限于该特定实施例，而是在适用的情况下具有可互换性并且可用于选定实施例中。它们也可以以许多方式发生变化。这样的变型并不被认为是背离本公开，并且所有这样的修改旨在被包括在本公开的范围内。
