叶片安装板也称为缘板,是指叶片上与叶身圆滑转接形成通道的部分,对导向器叶片来说,指与机匣相连的外安装板和与内环相连的内安装板,在叶片装配中,安装板内侧面分别与发动机气道内外环齐平,保证气道通畅,安装板侧面与相邻叶片安装板侧面或装配部位相配。检测导向器叶片安装板侧面的弦长尺寸,内外安装板盆背侧面均为双斜面,结构尺寸复杂,保证每两个叶片连接处有一定间隙,导向器叶片弦长尺寸直接影响相邻叶片之间的正确安装位置,是发动机叶片检测的重要尺寸。
The blade mounting plate, also referred to as the edge plate, refers to the part of the blade that forms the passage with the blade body smoothly and smoothly. For the guide blades, it refers to the outer mounting plate connected with the casing and the inner mounting plate connected with the inner ring, In the blade assembly, the inner side of the mounting plate is flush with the inner and outer rings of the air passage of the engine, respectively, to ensure the smooth air passage. The side of the mounting plate is matched with the side or assembly site of the adjacent mounting plate of the blade. Detecting the chord length of the side of the guide vane mounting plate, the back side of the inner and the outer mounting plate basins are all double bevels, the structure size is complex, and there is a certain gap between every two vanes. The chord length of the guide vanes directly affects the adjacent vanes Between the correct installation location, is an important engine blade detection size.
