    • The invention relates to a method for mounting vanes (10) in the periphery of a turbine engine disc (12), the disc (12) comprising cavities extending alternately with teeth, the vanes (10) respectively comprising: roots to be inserted into the cavities, shrouds (26), and blades (24) connecting the roots to the shrouds. According to the invention, the method comprises the following steps: (a) positioning the vanes (10) such that the root of each blade is axially facing one of the cavities of the disc; (b) providing a mounting tool (50) comprising a tip (40) with a shape partially matching the shroud (26) of one of the vanes; (c) engaging the tip (40) of the mounting tool (50) with the shroud (26) of the vane; (d) pivoting the shroud (26) of the vane by rotating (54) the mounting tool (50); and (e) axially inserting the root of the vane into the cavity of the disc.
    • 本发明涉及一种用于将叶片(10)安装在涡轮发动机盘(12)周围的方法,所述盘(12)包括与齿交替延伸的空腔,所述叶片(10)分别包括:根部,所述根部插入 空腔,护罩(26)以及将根部连接到护罩的叶片(24)。 根据本发明,该方法包括以下步骤:(a)定位叶片(10),使得每个叶片的根部轴向地面向盘的一个空腔; (b)提供包括尖端(40)的安装工具(50),所述尖端(40)具有与所述叶片之一的所述护罩(26)部分地匹配的形状; (c)将安装工具(50)的末端(40)与叶片的护罩(26)接合; (d)通过旋转(54)安装工具(50)来枢转叶片的护罩(26); 和(e)将叶片的根部轴向插入盘的空腔中。
