Abstract
一种用于在相对的表面之间产生密封的垫圈，其具有用于支撑彼此为间隔开关系的独立囊珠的主体。该囊珠填充有液体密封剂，并且在该相对的表面之间施加压力下，可彼此破裂。破裂后，该液体密封剂被释放，以均一地在该表面之间流动，以产生二者之间可靠的密封。
Description
技术领域
本发明大致涉及垫圈。
背景技术
通常使用垫圈以在相对的表面之间产生密封，并在内燃机和许多车辆部件(例如泵)中尤其有用。为确保相对的表面之间的良好密封，通常地，液体密封剂和单独的垫圈彼此相结合，夹制于该表面之间。典型地，直接将密封剂应用到该相对的表面中的至少一个，和/或应用到该垫圈的至少一个侧面。尽管这可产生良好密封，但其通常会给组装过程增加时间和费用。发明内容一种用于在相对的表面之间产生密封的垫圈，其具有用于支撑彼此为间隔开关系的独立囊珠的主体。该囊珠填充有液体密封剂，并且在该相对的表面之间施加压力下，可彼此破裂。在该相对的表面之间破裂后，该液体密封剂被释放，以在该表面之间流动，以产生二者之间可靠的密封。本发明的另一个方面提供了一种制造用于在相对的表面之间产生均一、可靠密封的垫圈的方法。该方法包括由可破裂的隔膜形成多个独立的可破裂的囊珠，并包裹一液体密封剂在该囊珠内。另外，将这些囊珠彼此结合，以形成该囊珠的柔性串。
附图说明
结合以下具体描述和附图，本发明的这些和其它特征及优点将会被更加容易地理解，其中：
图1是根据本发明的一个当前优选实施方式，显示出液体密封剂囊状垫圈的分解示意图，其设置装配于内燃机的发动机本体和承油盘之间；
图2是从图1中垫圈截取的开环的串部分的俯视图；
图3是根据本发明另一个实施方式构成的垫圈的俯视图；
图4是图3中沿线4-4的横截面视图；以及
图5是图3中沿线5-5的横截面视图。
具体实施方式
更具体地参照附图，图1显示了根据本发明一个当前优选实施方式的液体密封剂囊状垫圈10，其设置为用于相对的表面之间的组装，例如，在内燃机16的承油盘12和发动机本体14之间。垫圈10具有主体18，其支撑多个独立的载液囊珠20，此处通过示例而非局限的方式，囊珠20分布为绕闭环的周缘彼此大致上等距隔开。在组装中，当承油盘12通过例如螺纹固定方式连接到发动机本体14时，垫圈10的囊珠20在相对的表面或者凸缘22、24之间受压。在凸缘22、24之间所施加的压力下，单个囊珠20彼此独立地破裂。当囊珠20破裂时，液体密封剂从囊珠20释放，并均一地涂覆在相互配合的凸缘22、24之间的表面区域，从而在凸缘22、24之间建立均一、可靠的密封。
尽管图1中所示的垫圈10为通过连接部分26彼此连接的囊珠20形成的连续柔性串环，但该垫圈10也可形成为囊珠20的开环串，如图2所示，其中图1中所示垫圈10的一部分已被切除。如果形成为闭环，该环构成为具有预定周缘，从而可被控制为符合于将要被密封的相配合的表面的周缘形状。否则，如果构成为开环串，可根据其长度，使用一个或多个囊珠串20，以延伸将要被密封的表面。
如图2所示，为便于在组装中使垫圈10在凸缘22、24之间保持置位，可在囊珠20的外表面涂覆粘结剂27。可在制造垫圈10的过程中或者其后的任何时间，直接将粘结剂27涂覆在该外表面。如果在制造过程中涂覆，可在粘合剂上应用离型纸(release paper)等，以容许容易地处理和/或储存垫圈10，以供将来使用。因此，可在组装过程中，通过移除离型纸，有选择地暴露粘结剂27，从而有助于将垫圈保持在期望的位置，直到凸缘22、24彼此连接。
囊珠20显示为通过柔性连接部分26彼此连接，并且囊珠20的外表面由该部分26横向地向外延伸。柔性连接部分26容许弯曲和控制垫圈，以符合于任何期望的形状。因此，垫圈10可广泛地用于多种具有不同形状周缘表面的并将彼此密封的场合。如上所述，当一种应用场合具有不同于闭环垫圈的将被密封的环状周缘或其它尺寸时，可通过切除一个或多个连接部分26而同时不破裂任何囊珠20，而将闭环转化为开环串。因此，所得的开环串或串段可用于密封与原始闭环不同长度或周长的表面。
图1和2显示了垫圈10的囊珠20和连接部分26，通过示例而非局限的方式，该垫圈10由任何合适的垫圈材料整片构成，例如硅树脂、聚四氟乙烯(PTFE)、聚酯纤维、或天然橡胶。因此，用于形成囊珠20和连接26的材料可涂覆以由囊珠20释放的液体密封剂，以利用产生该相对的表面之间的密封。
囊珠20可横向地彼此间隔开，并大小设计为符合特定应用的密封要求。由此，在囊珠20内包裹的液体密封剂的量和位置以及使用中的扩散可被控制，以最大化形成的密封的完整性，同时最小化对液体密封剂的浪费。应当认识到，一个串或环内的单个囊珠的形状和大小，以及它们的位置，可以变化，以符合应用中具体的密封要求。
除了能够改变囊珠20的大小和形状之外，在各囊珠内包裹的液体密封剂的类型也可以变化。由此，垫圈10的一个部分可由囊珠20构造而成，囊珠20具有最适合于被其密封的区域的一种类型的液体密封剂，而垫圈10的另一个部分可具有另一囊珠20，其填充有最适合于被其密封的区域的另一种类型的液体密封剂。另外，应当认识到，具有活性成分(例如，环氧树脂)的液体密封剂，可以使其活性成分包括在相邻的囊珠20内并为非活性状态的活性成分。例如，例如，一个囊珠20内可包括硬化剂，而相邻的囊珠可包括可与硬化剂相反应的树脂。由此，当相邻囊珠20破裂时，树脂和硬化剂可混合并反应，从而产生在该相对表面之间的密封结合。
根据本发明一个实施方式构成的垫圈30如图3所示。垫圈30具有大致上平坦的主体32，其由任何合适的垫圈材料形成，例如，纸基材料、橡胶、软木、硅树脂和金属，或者该主体32依需要可由前述材料的一种或多种而制成。例如，垫圈主体32的一个部分34可由橡胶制成，而另一个部分36可由金属制成。另外，主体32的至少一部分(图未示)可具有凸纹(raisedrib)等，其可通过例如冲压或压纹工艺形成。
垫圈30具有多个由主体32支撑的载液囊珠38。如上所述，囊珠38间隔开，且尺寸设计为提供期望的密封剂分配。如图4所示，可通过使用比如粘结层43，将囊珠38连接到主体32的相对表面40、42，从而囊珠可从表面40、42横向向外延伸。以示例而非局限的方式，此处的囊珠38显示为彼此相对，但它们也可设置为彼此交错的关系。如上所述，囊珠38可包裹不同类型的液体密封剂，以最好地达到良好、可靠的密封。例如，在垫圈30金属部分36内的囊珠38可具有一种类型的液体密封剂，而在垫圈30橡胶部分34内的囊珠38可具有不同类型的液体密封剂。另外，应当理解，连接到一个表面40的囊珠38可具有与连接到相对表面42的囊珠38不同的液体密封剂。
如图5所示，主体32可具有贯通开口44，用于接收囊珠38，而不是将囊珠38连接到表面40、42。该贯通开口44尺寸可设计为贴合地接收囊珠38，从而它们可保持在其内，并优选地由其向外延伸，或者可使用粘结剂以利于它们的固定。因此，当破裂时，一个囊珠可用于在相对的表面40、42上同时释放液体密封剂。
当囊珠38从表面40、42横向向外延伸时，囊珠可先于主体32受压，从而在对主体32的任何显著压迫之前，并优选地在该相对的表面密封地结合主体32之前，使囊珠38破裂。因此，从囊珠38释放出来的液体密封剂在由将被密封的相对表面结合之前，大致上自由地在表面40、42上均一流动，从而有利于产生可靠和均一的密封。
明显地，根据以上教导，本发明的其他修正和变形是可能的。因此，应当理解，在后附权力要求的范围内，本发明可以不同于以上具体描述的其他方式实施。
