Description

用于唇缘的涂层的改进的工具装置
技术领域
本发明涉及涡轮喷气发动机领域，并且更具体地旨在产生用于涡轮喷气发动机的耐磨材料的轨道。
背景技术
涡轮喷气发动机以已知方式包括通常称为迷宫式密封的密封部分，这种密封特别有利于实现旋转部件之间的密封。迷宫式密封一方面包括在一个部件上产生的耐磨材料的轨迹，另一方面包括在另一部件上形成，并适于与耐磨材料的轨迹接触的一组唇缘，该接触实现了密封功能。
在操作期间，由于唇缘抵靠所述轨道的摩擦，唇缘和轨道之间的接触导致轨道的磨损。反复出现的问题是耐磨材料从轨道到唇缘的转移，以及唇缘涂层，通常是陶瓷材料涂层的磨损。
耐磨性尤其取决于用于在唇缘上沉积涂层的方法。通常将陶瓷材料喷涂到唇缘上。涂层耐磨性的决定性参数是喷涂角度。实际上，喷雾角度越闭合，陶瓷材料的附着力越弱。通常，由于严重影响涂层内聚力的烟囱中孔隙的形成，因此以小于30°的喷涂角度进行喷涂会导致非常低的附着力(更通常称为阴影现象)。然而，转子段的几何形状，尤其是设置有叶片的转子的几何形状对于涂层的喷涂是有问题的，并且仅允许使用在10°数量级的非常小的喷涂角度。
图1表示涡轮发动机的转子扇区1的实施例，该扇区包括多个叶片根部11，在这些叶片根部之间定位有唇缘2。转子扇区1是叶片扇区。叶片根部11分别与相对于转子扇区1的中心轴线(未示出)径向地延伸的叶片12相关联。图2是唇缘2的实施例的详细视图，示意了唇缘2上的唇缘主体21和涂层22，该涂层22通常由陶瓷材料制成。
从图1容易理解，叶片根部11和叶片12的存在限制了在唇缘2上喷涂涂层的可能性。
发明内容
为了至少部分地应对这些问题，本公开涉及一种用于涡轮发动机转子扇区的唇缘的涂层的工具装置，其包括用于转子扇区的支撑件，适于插入到转子扇区中的定心板，所述定心板具有中心套，包括定心臂的工具，所述定心臂适于被插入到定心板的中心套中，适于喷涂陶瓷材料的喷炬，以及机加工工具，所述工具装置配置为通过定心板，相对于转子扇区定位工具，并同时地在转子扇区上进行唇缘的两个不同扇区上的陶瓷材料的喷涂和机加工。
根据一个实施例，将喷炬和机加工工具定位在定心臂的两侧。
可选地，定心臂和定心板包括旋转装置，该旋转装置允许定心臂相对于定心板的相对旋转。
然后，支撑件通常可相对于工具旋转运动。
根据一个实施例，机加工工具和喷炬各自相对于定心臂可滑动地安装。
机加工工具包括例如，切割部分，该切割部分的形状对应于待加工的唇缘的负片。
本发明还涉及一种用于形成涡轮发动机转子扇区的唇缘的耐磨涂层的方法，其中：提供包括多个唇缘的涡轮发动机转子扇区，转子扇区定位在支撑件上，定心板固定在转子扇区的开放端，转子扇区的相对端放置在支撑件上，所述定心板具有中心套，通过将定心臂插入到定心板的中心套，将工具相对于转子扇区定位，所述工具设有喷炬和机加工工具，驱动转子扇区相对于该工具旋转，喷炬被致动以将陶瓷材料喷涂到转子扇区的唇缘上，机加工工具被定位成机加工所述唇缘，同时通过喷炬进行陶瓷材料的喷涂。
可选地，所述方法还包括：移除机加工工具的步骤，并且进行将陶瓷材料喷涂到唇缘上的步骤。
附图说明
通过阅读以下通过非限制性实施例给出的本发明不同实施方式的详细描述，将更好地理解本发明及其优点。本说明书参考了附图页面，在这些附图页面上：
图1：上述图1是转子扇区的视图。
图2：上述图2是图1的转子扇区的详细视图。
图3：图3示意性地表示根据本发明一方面的工具装置和方法。
图4：图4示意性地表示根据本发明一个方面的工具装置和方法。
图5：图5示意性地表示根据本发明的一方面的工具装置和方法。
在所有附图中，共同的元件由相同的附图标记标识。
具体实施方式
图3，图4和图5示意性地表示根据本发明一个方面的工具装置和方法，不同的图表示根据本发明的方法的连续步骤。
图3表示涡轮发动机的转子扇区1，其包括多个叶片根部11，多个叶片12以及设置在连续的叶片根部11之间的多个唇缘2。在第一步骤期间，转子扇区1定位于支撑件3上；转子扇区1的一端(相对于转子扇区1的中心轴线Z-Z)因此被放置在支撑件3上，然后其相对端是自由的。唇缘2通常类似于已经参考图2呈现的唇缘。
图4表示下一步骤，其中定心板4已定位在转子扇区1的自由端上。
定心板4通常通过螺栓固定在转子扇区1的凸缘上。转子扇区1的凸缘和用于使定心板4定心的装置(例如孔)确保了定心板4相对于转子扇区1的定位，特别是定心。定心板4具有适于接收定心臂的中心套41，稍后将对此进行描述。中心套通常相对于转子扇区1的中心轴线Z-Z对准并同轴。
在图5中示意的下一步骤中，相对于转子扇区1定位工具5。
工具5包括定心臂6，喷炬7和机加工工具8。工具5固定到固定的支撑件。
定心臂6的自由端61适于插入到定心板4的中心套41中。
在所示的实施例中，中心套41是截头圆锥形通孔。定心臂6的自由端61也具有截头圆锥形的形状，其允许与形成中心套41的截头圆锥形孔接合和定心。应当理解，该实施方式不是限制性的，并且该定心臂6的自由端61和定心板4的中心套41可以采用任何合适的形状，只要它们允许工具5相对于定心板4接合即可。
定心板4或定心臂6通常具有允许这两个元件沿着与转子扇区1的中心轴线Z-Z相对应的轴线相对旋转的元件。例如，定心板4或定心臂6可以具有轴承，诸如滚柱轴承，其确保定心板4相对于定心臂6的这种相对旋转。定心臂6的自由端61可以，例如由圆锥形或截头圆锥形的轴承形成。这样既确保了定心，又确保了沿着轴承的旋转轴线旋转的可能性，然后，该旋转轴线有利地与转子扇区1的中心轴线Z-Z同轴。可替代地，定心板4在其中心套处可以具有轴承(例如，圆锥形或截头圆锥形轴承)，定心臂6接合在其中。
如上所述，工具5包括喷炬7和机加工工具8，它们分别定位在从定心臂6延伸的臂上，所述臂是可调节高度的(沿中心轴线Z-Z)和可调节长度的(相对于中心轴线Z-Z径向地)，以确保相对于转子扇区1的良好定位。
喷炬7进行陶瓷材料的喷涂，以便在转子扇区1的唇缘2上形成涂层。它通常定位在形成工具5的可移动部分的第一臂上，以便能够被定位在唇缘2的前面，以便进行陶瓷材料的喷涂。因此，喷炬7通常可相对于转子扇区1的中心轴线Z-Z，沿径向方向平移运动。
机加工工具8定位在形成工具5的可移动部分的第二臂上，使得其可以面对唇缘2被定位并进行唇缘2的机加工。因此，机加工工具8通常可相对于转子扇区1的中心轴线Z-Z，沿径向方向平移运动。机加工工具8通常与阻尼系统相关联，该阻尼系统允许将其施加在待加工的部件上，同时避免机加工工具8在待机加工的转子扇区1上在其旋转期间可能的回弹。阻尼系统通常包括经过校准的复位装置，例如弹簧，以便向唇缘2施加预定的机加工压力。
机加工工具8通常具有与待加工的唇缘2的形状互补的形状，因此机加工工具8的精度调节所进行的机加工的精度。
定位机加工工具8和喷炬7使其面向转子扇区1的不同部分。更准确地说，如果考虑转子扇区1具有几组不同的唇缘，每个唇缘在转子扇区1整个周边上延伸。然后，通常定位机加工工具8和喷炬7，使得它们同时地面对相同组的唇缘，但是沿着转子扇区1的两个不同的角度扇区。因此，喷炬7可以在一个或几个唇缘的角度扇形上进行陶瓷材料的喷涂，而机加工工具8将机加工该或这些相同唇缘的另一角度扇形。因此，在转子扇区1的两个不同的区域上同时地进行由机加工工具8进行的机加工和由喷炬7进行的喷涂的操作。
典型地，工具5构造成使得机加工工具8和喷炬7被定位在转子扇区1的中心轴线Z-Z的两侧，即定位在定心臂的中心轴线的两侧。或者当定心臂6插入到定心板4的中心套41中时，甚至相对于中心轴线Z-Z形成180°角。
因此，一旦工具5相对于转子扇区1被定位，就进行喷涂步骤，其中同时地进行涂层的喷涂和唇缘2的机加工的操作。然后，通常由支撑件3驱动转子扇区1相对于工具5旋转，例如以每分钟200转的速度旋转。然后可以控制机加工工具8相对于中心轴线Z-Z的径向位移，以便监控机加工。
可选地，然后单独地进行陶瓷材料喷涂的附加操作，而不进行机加工操作，以使唇缘2的粗糙度等于通过常规方法获得的粗糙度，这允许确保唇缘2良好地穿入到通常具有蜂窝结构的耐磨材料的轨道中。例如，可以通过使机加工工具8缩回来进行该步骤。
因此，相对于常规工具装置和方法，所呈现的工具装置和方法具有几个优点。
首先，要理解，工具5在此直接相对于该部件，即相对于转子扇区1被定位。更具体地，使用固定到转子扇区1的定心板4允许工具5相对于转子扇区1定位，不同于常规的工具装置中工具是固定的，并且部件相对于工具被定位。相对于部件1定位工具5的事实使得可以省去部件的定心调节，这里由于定心板4和定心臂6之间的配合而进行定心。
此外，同时地进行喷涂和机加工操作的事实允许防止或至少限制烟囱中孔隙的形成。实际上，机加工工具8磨耗在两次沉积操作之间的涂层，从而防止了烟囱中的孔隙的形成，因为随后涂层的堆积被机加工工具8磨耗了。因此，机加工工具允许整平由喷炬7进行的每次材料沉积操作之间的涂层。
另外，同时地进行喷涂和机加工操作的事实使得可以省去随后的机加工操作；在此，唇缘2直接地形成有期望尺寸的涂层。
尽管已经参考特定的示例性实施方式描述了本发明，但是显而易见的是，可以对这些实施例进行修改和改变，而不脱离由权利要求书限定的本发明的总体范围。特别地，可以在另外的实施方式中组合各种示例/提到的实施方式的各个特征。因此，应当以说明性而非限制性的意义来考虑说明书和附图。
