Abstract

本实用新型提供了一种25000机组末级动叶,包括叶身和叶根,所述叶身与叶根整体成型,所述叶根为纵齿形叶根;所述叶根两侧设有对称的卡齿。本实用新型的叶根采用了纵齿形叶根,增大了叶根与叶轮的接触面积,从而提高了叶根与叶轮连接的稳定性,使叶根与叶轮不易脱离,整体上提高了稳定性。

Description

一种25000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25000机组末级动叶。
背景技术
目前,市场上所生产使用的25000机组末级动叶所采用的叶根为T型叶根,该种叶根由于T型小角刚度低,易发生折断或变形,影响了叶片与叶轮安装连接的稳定性。
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25000机组末级动叶。
为解决上述技术问题,本实用新型的一种25000机组末级动叶,包括叶身和叶根,所述叶身与叶根整体成型,其特征在于:所述叶根为纵齿形叶根。
所述叶根两侧设有对称的卡齿。
以上结构的优点在于:所述25000机组末级动叶叶根采用了纵齿形叶根,增大了叶根与叶轮的接触面积,从而提高了叶根与叶轮连接的稳定性,使叶根与叶轮不易脱离,整体上提高了稳定性。
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,25000机组末级动叶包括叶身1和叶根2,所述叶根2呈纵齿形,两侧还均匀分布有卡齿3,所述叶身1,叶根2和卡齿3均整体成型。

Claims (2)
