Abstract

本实用新型提供了一种13500机组末级动叶,包括叶冠、叶身和叶根,所述叶冠、叶身和叶根三者整体成型,且叶根为锥形叶根;所述锥形叶根内腔等距离分布有卡齿。本装置的叶根采用前后插置,由于叶根为锥形,同时叶根内腔均匀分布有卡齿,增大了叶根和汽轮的叶轮的接触面积,受力均匀,提高了叶片的整体稳定性。

Description

一种13500机组末级动叶
技术领域
本实用新型涉及一种机组末级动叶,特别是一种13500机组末级动叶。
背景技术
目前,该种机组末级动叶采用Y型叉形叶根,从上往下进行插置,再通过叶根底段两小槽使用插销紧固,若插销发生松动或断裂则叶片由于高速旋转会飞出,发生意外。
实用新型内容
本实用新型提供了一种机组末级动叶,特别是一种13500机组末级动叶。
为解决上述技术问题,本实用新型的一种13500机组末级动叶,包括叶冠、叶身和叶根,所述叶冠、叶身和叶根三者整体成型,其特征在于:所述叶根为锥形叶根。
所述锥形叶根内腔等距离分布有卡齿。
以上结构的优点在于:所述13500机组末级动叶的叶根采用前后插置,由于叶根为锥形,同时叶根内腔均匀分布有卡齿,增大了叶根和汽轮的叶轮的接触面积,受力均匀,提高了叶片的整体稳定性。
附图说明
图示为本实用新型的结构示意图。
具体实施方式
下面结合附图对本实用新型的具体实施方式作进一步说明
如图所示,13500机组末级动叶由叶冠1,叶身2和叶根3组成,所述叶根3为锥形,叶根3内腔均匀分布有卡齿4,叶身2为不规则的扇形面,所述叶冠1,叶身2和叶根3整体成型。

Claims (2)

1、一种13500机组末级动叶,包括叶冠、叶身和叶根,所述叶冠、叶身和叶根三者整体成型,其特征在于:所述叶根为锥形叶根。
2、根据权利要求1所述的一种13500机组末级动叶,其特征在于:所述锥形叶根内腔等距离分布有卡齿。
