Abstract

本实用新型涉及一种适用于大型抽水蓄能机组带中间环的顶轴，由顶轴本体、卡环、中间环、滑转子组成，该顶轴在顶轴本体和滑转子之间设计了中间环，这样使挡油管不需要设计成分瓣结构，直接由上端套入。可以避免分瓣挡油管合缝位置渗漏油的风险。

Description

适用于大型抽水蓄能机组带中间环的顶轴
技术领域：本实用新型涉及本实用新型涉及了一种适用于大型抽水蓄能机组带中间环的顶轴。
背景技术：常规水轮发电机顶轴的设计是在顶轴本体上设计出一圈凸台。然后将滑转子热套在顶轴本体外圆的凸台上。这样的话，由于布置在滑转子下方的挡油管的内圆小于顶轴本体的外圆，所以必须将挡油管设计成分瓣结构，存在一个合缝面，就增加了可能渗漏油的风险。
发明内容：本实用新型的目的是公开一种结构简单的一种适用于大型抽水蓄能机组带中间环的顶轴。本实用新型的技术方案为：由顶轴本体(1)、卡环(2)、中间环(3)、滑转子(4)组成，中间环(3)套在顶轴本体(1)上，用卡环(2)固定在顶轴本体(1)上，滑转子(4)热套在中间环(3)外圆，挡油管(5)不需要设计成分瓣结构，直接由上端套入。
