Description

带凸缘的轴承外环单元
技术领域
本发明涉及一种根据权利要求1的带凸缘的轴承外环单元。本发明还涉及一种根据权利要求7的用于制造这种带凸缘的轴承外环单元的模制件。此外，本发明涉及一种根据权利要求8的包括这种带凸缘的轴承外环单元的轴承组件。此外，本发明涉及一种根据权利要求9的用于制造带凸缘的轴承外环单元的方法以及一种根据权利要求10的用于制造轴承组件的方法。
背景技术
带凸缘的轴承可以用于通过凸缘在其端部位置自动对准轴承，这意味着凸缘连接到轴承以允许轴承的自对准。因此，滚动轴承和凸缘之间存在滑动界面。例如，在航空航天工业中，尤其是在诸如飞行指令、动力传动装置、致动器等的应用中，这种带凸缘的轴承可以实施为轻质轴承。这些轻质带凸缘的轴承通常具有薄的凸缘，该凸缘是轴承外环的延伸部或者是包含滚动轴承本身的球面滑动轴承的外环的延伸部。
凸缘通常由加工钢制成，厚度仅为几毫米。在铣削或车削加工钢之后，可以研磨凸缘以在滑动界面处获得正确的表面粗糙度和几何形状。因此，当加工这些凸缘时，通常浪费许多材料以实现所需的薄几何形状。此外，当使用钢凸缘，即不是由不锈钢制成时，可能必须保护表面免受腐蚀，这需要特定的涂层。
发明内容
因此，本发明的目的是提供一种用于轴承的外环，其具有带有用于自对准的凸缘的滑动界面，其中凸缘的制造被简化并且提供较少的材料浪费。
该目的通过根据权利要求1的带凸缘的轴承外环单元解决。
带凸缘的轴承外环单元包括由金属制成的外环和附接到外环的滑动界面的凸缘。为了减少材料浪费，凸缘由聚合物材料制成并通过注射模制附接到滑动界面。由于凸缘可以通过直接围绕外环和在外环处注塑模制而形成，所以凸缘可以以预期的最终形式模制，而不需要例如通过研磨来移除材料。此外，研磨将会是更具成本和时间昂贵的方法。此外，由于凸缘由聚合物材料构成，因此与钢凸缘相比，不需要另外的特定涂层来保护凸缘免受腐蚀。
聚合物材料可以是热塑性材料，例如聚醚醚酮(PEEK)。众所周知，热塑性材料在注入时不一定与金属结合。当围绕由金属制成的外环形成凸缘时，将热塑性材料注入模制件中。在模制件中，热塑性材料围绕外环。在热塑性塑料和金属球形式的外环之间，当金属球在模制之后由热塑性塑料形成的腔内滑动时，形成球形接头。不需要进一步研磨凸缘的热塑性材料以获得正确的调整。已经完成组装而没有任何进一步的制造步骤，而当加工钢凸缘时，将会需要进一步完成或完工步骤。
通过使用热塑性聚合物作为凸缘的聚合物材料，可以形成轻质凸缘，从而形成轴承。为了增强凸缘的稳定性，聚合物材料可以通过纤维增强，例如玻璃纤维或碳纤维。
在一实施例中，聚合物材料可以通过使用嵌入的金属片或有机片来增强，所述金属片或有机片可以是用纤维层增强的预固结热塑性材料片。纤维可以是玻璃纤维或碳纤维。
可以将有机片切割、加热并立即放入模制件中，其中有机片填充将形成凸缘的腔的一部分。随后，在腔中填充聚合物材料，该聚合物材料围绕有机片模制。由于有机片在强度和刚度方面比聚合物例如热塑性材料具有更高的性能。因此，可以改善凸缘的强度和刚度方面的性能水平。
通过使用注射模制形成带凸缘的轴承外环单元，可以在使用较轻材料时减小整个轴承的重量。此外，与制造金属凸缘相比，由于聚合物凸缘的制造更容易且更快，因此可以降低制造轴承的成本。此外，注射模制可以允许制造通过车削不能获得的形状。
在另一方面，提供了一种用于制成如上所述的带凸缘的轴承外环单元的模制件。模制件包括第一模制部分和第二模制部分。第一模制部分、第二模制部分和外环形成可填充有聚合物材料的腔，用于将凸缘包覆模制到外环的滑动界面上，如上所述。
第一模制部分和第二模制部分可以设置在彼此之上，在其间形成腔。其中一个部分可包括用于接收包含聚合物材料并适于注入聚合物材料的注射装置的开口。外环可以封闭腔的一侧，使得注入的聚合物材料可以包覆模制到外环的滑动界面上。此外，在注入聚合物材料之前，可以用有机片填充模制件，以提供加强的凸缘。
根据另一方面，提供了一种轴承组件，其包括内环和如上所述的带凸缘的轴承外环单元。滚动元件布置在内环和带凸缘的轴承外环单元之间，其中滑动界面设置在带凸缘的轴承外环单元的凸缘和外环之间。如上所述，这种轴承组件可以是轻质组件，因为凸缘由聚合物材料而不是钢制成。此外，与具有钢凸缘的轴承组件相比，整个轴承组件的制造成本可以降低，因为可以简化制造。不再需要从外环移除材料以形成凸缘，因此可省略加工和研磨步骤。
根据另一方面，提供了一种用于制造如上所述的带凸缘的轴承外环单元的方法。首先，提供外环，其可以使用机械加工、热处理、研磨以及必要时的表面处理来制造，以提供具有截头球形外表面的轴承外环。
然后将外环置于如上所述的模制件中，其中模制件由外环、第一模制部分和第二模制部分封闭。注射装置可以与模制件联接，用于用聚合物材料填充模制件的腔。一旦聚合物例如热塑性材料冷却至冷冻温度，可以通过移除第一模制部分和第二模制部分来使带凸缘的轴承外环单元脱模。在此步骤之后，带凸缘的轴承外环单元由嵌入聚合物凸缘中的轴承外环构成。
根据另一方面，提供了一种用于制造轴承组件的方法。除了如上所述的制造带凸缘的轴承外环单元的步骤之外，用于制造轴承组件的方法还包括将滚动元件和内环组装到带凸缘的轴承外环单元的外环中的步骤。
在权利要求、说明书和附图中公开了其他优点和优选实施例。应进一步指出，本领域技术人员可以单独地考虑或使用所呈现的特征，或者在不扩展本发明的范围的情况下除了指示之外组合所呈现的特征。
在下文中，将通过附图中所示的实施例来描述本发明。所示实施例仅是示例性的，并不旨在限制保护范围。保护范围仅由所附权利要求限定。

具体实施方式
图1示出了用于制造带凸缘的轴承外环单元的模制件1。带凸缘的轴承外环单元包括外环2和凸缘4，凸缘4附接到外环2的滑动界面6。
模制件1包括第一模制部分8和第二模制部分10。第一模制部分8和第二模制部分10设置在彼此之上。模制件1的一侧由外环2封闭，如图1所示。
在将模制件1放在一起之后，将聚合物材料填充到在第一模制部分8、第二模制部分10和外环2之间形成的腔中。聚合物材料例如热塑性材料通过形成在第一模制部分8中的开口12注入。为了注入聚合物材料，可以使用注射装置14，其可以联接到开口12。
在将聚合物材料填充到腔中之后，冷却聚合物材料。当滑动界面6形成腔的一侧时，聚合物材料直接模制到滑动界面6上。在聚合物材料完全冷却，特别是冷却到冷冻温度之后，通过移除第一模制部分8和第二模制部分10使带凸缘的轴承外环单元16脱模。
作为最后一步，滚动元件和内环可以安装到带凸缘的轴承外环单元16的外环2上，以制造完整的轴承组件。
因此，凸缘4可以容易地附接到外环2的滑动界面6上，以允许外环2的自对准。由于凸缘4由聚合物材料制成，所以整个轴承组件可以制成比使用钢凸缘的轴承组件更轻。此外，这种聚合物凸缘的制造比钢凸缘的制造更容易，因为不需要进一步研磨外环材料以获得凸缘的正确尺寸。
为了加强聚合物凸缘4，有机片18可以嵌入聚合物材料中，如图2所示。有机片18是由纤维(例如碳纤维或玻璃纤维)层增强的预固结热塑性材料片。
在用聚合物材料填充模制件1之前，可以将有机片18放入模制件1中。当模制件1的腔填充有聚合物材料时，聚合物材料围绕有机片模制。通过使用这种有机片，可以向聚合物材料中添加更高程度的强度和刚度，从而提高凸缘4的强度和刚度。
总之，当如上所述制造聚合物凸缘和用于轴承的具有带有用于自对准的聚合物凸缘的滑动界面的外环时，可以简化制造并且可以减少材料浪费，因为不需要在凸缘上进行研磨等。
