Description

用于通过感应来分离粘附到一机械零件上的磁机械零件
技术领域
本发明涉及机械组件的维修领域，更具体说，是涉及飞机涡轮轴引擎的损坏的磁机械零件的替换。
背景技术
飞机涡轮轴引擎包括具有由复合材料制成的主体的叶片，其前边缘被金属罩所覆盖。该由复合材料制成的叶片主体通常包括碳纤维增强热固性树脂。按通常的做法，该金属罩利用一覆盖其内部分的粘性薄膜而被牢固地连接到该叶片的前边缘。随着时间的推移，该罩劣化，需要在维修操作过程中更换它，在该维修操作过程中，该叶片经历不同的加工步骤（分裂、剥离、牵引等），以去除磨损的罩。在适当的检查和表面准备之后，一个新的金属罩通过使用粘性薄膜被粘接到该叶片的边缘。
这样的维修过程具有几个缺点。首先，连续的加工步骤可能损坏叶片并造成纤维从叶片主体撕下，这限制叶片的寿命或导致其废弃。
另一方面，常规的对流、传导或辐射热的使用以削弱粘性薄膜的粘性特征并有利于其去除被证明存在损坏叶片主体的树脂，并降低由复合材料制成的叶片的几何性质的风险。
上述维修过程因此不适合满足现有需求。
发明内容
尽管本发明起于涡轮轴引擎叶片的维修问题，但本发明通常涉及利用粘性薄膜牢固地连接到另一机械零件上的任何磁机械零件的更换。
为此，本发明涉及一种用于将第一机械零件与磁性第二机械零件分离的方法，该第一机械零件利用一粘性薄膜沿一连接区域粘接到该磁性第二机械零件上，一方法其中磁场至少在该连接区域产生，以通过感应，在该磁性第二机械零件中产生涡电流，以软化该粘性薄膜，并使所述机械零件可分离。
磁场的产生使得可在不进行可改变一个或另一个机械零件的机加工的情况下分离该磁性第二机械零件。该磁场在该第二机械零件中感应涡电流，并由于其磁特性而使其加热。该磁性第二机械零件的连接表面的温度升高造成，在一方面，所述粘性薄膜的加热，这软化并损失部分其粘性，在另一方面，造成该磁性第二机械零件的热膨胀。两机械零件之间的热膨胀导致该粘性薄膜与该磁性第二机械零件之间的机械切削。该磁性第二机械零件的分离因此不需要机械加工。
优选地，仅连接区域放入磁场中，这使得可局部加热该磁性第二机械零件而不改变其寿命。
此外，本发明还涉及一种用于将第一机械零件牢固地连接到磁性第二机械零件的方法，方法其中沿一连接区域在第一机械零件与磁性第二机械零件之间应用一粘性薄膜，磁场至少在该连接区域产生，以通过感应，在该磁性第二机械零件中产生涡电流，以使该粘性薄膜聚合，并牢固地连接该两个机械零件。
磁场的应用使得可通过创造仅局部加热而迅速地牢固连接两机械零件。
优选地，仅所述连接区域设置在该磁场中，这使得可局部加热该磁性第二机械零件，而不改变其寿命。
优选地，该第一机械零件为由复合材料制成的零件，优选为非磁性的。由复合材料制成的机械零件无法通过感应而被加热，这使得可避免其损坏。
优选地，该第一机械零件为涡轮轴引擎叶片。涡轮轴引擎叶片的表面必须无任何刻痕。涡轮轴引擎叶片的此过程的实现使得可确保叶片的完整性。
仍然优选地，该涡轮轴引擎叶片由复合材料制成，优选具有有机基体。这样的复合材料通常是非磁性的，不传导涡电流，仅所述粘性薄膜在实现用于牢固连接或分离的本方法过程中由该磁性第二机械零件加热，所述涡轮轴引擎叶片不被同样地加热。此外，感应热非常短暂，这限制了由通过热固性树脂形成的复合材料制成的，由碳纤维加强的叶片受到热损害的风险。而且，该复合材料不通过在分离过程中进行的机械加工步骤而改变。复合零件的接触区域不再经受纤维的撕下。
根据本发明的一优选特征，该磁性第二机械零件为涡轮轴引擎叶片的罩。此罩优选由金属制成，本身具有磁性，使涡电流能够循环。在一有利方式中，损坏的罩从涡轮轴引擎叶片的去除和/或放置一新罩是简单和迅速的，粘性薄膜由必须被移除或放置的罩进行局部加热。当产生磁场时，仅对磁场敏感的金属罩受热升温，使得可完全保持由复合材料制成的该叶片的特性，特别是该复合材料的树脂的特性。
优选地，由于涡轮轴引擎叶片包括前边缘，因此该罩设置为粘接到叶片的该前边缘。
根据本发明的另一特征，该第一机械零件为涡轮轴引擎壳体，该第二机械零件为一磁性插件，该磁性插件设置为使设备能够安装在该涡轮轴引擎壳体上。
附图说明
通过参照附图来阅读以下仅作为一例子的说明，将能更好地理解本发明，其中根据一截面图，该仅有的附图示意性地显示一涡轮轴引擎叶片，其前边缘覆盖以一罩，该叶片的前边缘被放入由一感应器产生的磁场中。
具体实施方式
根据该仅有附图，本发明陈述一种涡轮轴引擎叶片1，该叶片具有前边缘2，该前边缘被一罩4覆盖，该罩4通过沿连接区域的粘性薄膜3而粘接到前边缘2上。换句话说，所述粘性薄膜3位于叶片1的前边缘2与罩4之间，如仅有的附图所示。
在此，该罩4由金属制成，但显然其他磁性材料也是适合的。
为从叶片1的前边缘2分离罩4，该前边缘2被放入由仅有的附图中示意性所示的感应器5所产生的磁场中。优选地，仅前边缘2的覆盖以粘性薄膜3的连接区域被放入该磁场中。
在该磁场的影响下，金属罩4由于由感应所产生的涡电流而受热升温，并将热卡传送给粘性薄膜3。该粘性薄膜受热升温，软化，其机械特性降低。此外，该罩4相对于叶片1热膨胀，其造成剪应力活跃，这导致罩4从叶片1的前边缘2脱离。该罩4随后可从前边缘2移除。在一有利方式中，不进行机械加工步骤，因此可限制叶片1损坏的风险。这对于由易受机械加工操作损坏的复合材料1制成的叶片是尤其有利的。
假设复合叶片，特别是具有有机基体的复合叶片不是磁性的，不能使产生涡电流的电子循环，则所述感应加热对于复合叶片1来说不具有风险。其结果是，仅与磁性罩4接触的粘性薄膜3受热升温，复合叶片1受到热损坏的风险大大降低。
感应加热使得可将一新罩牢固地连接到叶片1的前边缘2上，特别是在损坏的罩去除之后。
为了将罩4牢固地连接到由复合材料1制成的叶片的前边缘2上，在该前边缘2与刚通过利用感应器5的感应而被加热的罩4之间应用一粘性薄膜3。该粘性薄膜3在由罩4中的涡电流的循环所产生的热的影响下聚合。该罩4在前边缘2上固定就位，停止对粘性薄膜3的加热。粘性薄膜3固化，同时将罩4牢固地连接到前边缘2上。所获得的叶片1于是可安装在涡轮轴引擎上。
作为例子，由钛制成的罩4牢固地连接到由复合材料1，优选由包括碳纤维的有机材料制成的叶片的前边缘2上。根据一优选实施例，使用一种环氧型的胶质物，其厚度设置为一毫米级别。显然，由该感应器所产生的磁场的值必须根据所使用的胶质物和将牢固连接/分离的零件的组成材料而进行调节。
本发明对于将罩牢固地连接到涡轮轴引擎叶片/从涡轮轴引擎叶片脱离进行了说明，但是，当然，它可应用于任何将第一机械零件与磁性第二机械零件连接/分离的情况。本发明的目的尤其是替换优选由具有有机基体的复合材料制成的涡轮轴引擎壳体上的磁性金属插件。这样的金属插件特别能够将设备安装到涡轮轴引擎壳体上。
