实施例3
一种空调器，其包括具有叶轮轴的叶轮和具有电机输出轴的电机，在所述叶轮轴和所述电机输出轴之间设置有一连接装置，所述连接装置包括分别与叶轮和电机连接的两个连接件，分别为与叶轮固定连接的第一连接件和与电机输出轴固定连接的第二连接件，两个所述连接件之间具有非圆配合的传动连接结构；以及设置在两个所述连接件之间，引导所述传动连接结构相对旋转至配合状态的对准矫正机构。所述传动连接结构由沿电机输出轴线方向延伸的柱形部件11，适于所述柱形部件11插入的套筒12，以及固定在柱形部件11和套筒12两者之一上的所述凸舌与固定在两者另一个上的所述导型结构配合构成。本实施例中套筒12为六角套筒，柱形部件11为与所述六角套筒相适配的六角柱配合，凸舌21设置在六角柱上。
上述实施例中所述非圆配合为除了仅圆和圆的配合形式的所有其他传动配合，包括但不限于多边形传动配合、异形孔与异形柱配合、圆筒和圆筒套合后打孔破坏其圆的完整性后用柱销连接的传动配合方式等。
显然，上述实施例仅仅是为清楚地说明所作的举例，而并非对实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷 举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
