Description

一种高抗磨损、耐腐蚀的导叶轴
技术领域
本实用新型涉及一种高抗磨损、耐腐蚀的导叶轴。 
背景技术
目前，在水轮发电机组安装完毕并投入使用后，经过一段时间运行后发现导叶的轴部出现严重的磨损和腐蚀，经过分析得出的结论是由于水轮发电机组的导水机构要根据水的流量经常改变导叶打开或闭合的角度，这样会造成导叶的轴部与一种由不锈钢和铜等材料制成的高强度耐磨复合套进行不断的摩擦，而导叶的材质是铸钢件的，质地相对较软，经常造成导叶轴磨损。 
发明内容
本实用新型的目的是提供了一种解决了导叶轴易磨损、易腐蚀的问题，提高了产品质量，延长了使用寿命和检修周期，同时降低了维护成本的高抗磨损、耐腐蚀的导叶轴导叶轴。 
本实用新型的技术方案是：一种高抗磨损、耐腐蚀的导叶轴，其特征在于：导叶轴上套装有不锈钢套，在不锈钢套两端面的导叶轴上设有堆焊焊道，导叶轴与不锈钢套通过在堆焊焊道处的焊接固定。 
本实用新型具有的优点和积极效果是：采用了本实用新型的技术方案，完全解决了导叶轴易磨损、易腐蚀的问题，提高了产品质量，延长了使用寿命和检修周期，同时降低了维护成本。 
附图说明
图1是本实用新型的结构示意图； 
图2是图1中I所指部分的局部放大示意图。 
图中： 
1、导叶轴    2、不锈钢套    11、堆焊焊道 
具体实施方式
为进一步了解本实用新型内容、特点及功效，兹例举以下实例并结合附图详细说明如下： 
如图1、图2所示，一种高抗磨损、耐腐蚀的导叶轴，其特征在于：导叶轴1上套装 有不锈钢套2，在不锈钢套2两端面的导叶轴1上设有堆焊焊道11，导叶轴1与不锈钢套2通过在堆焊焊道11处的焊接固定。 
采用了本实用新型的技术方案，完全解决了导叶轴1易磨损、易腐蚀的问题，提高了产品质量，延长了使用寿命和检修周期，同时降低了维护成本。 
以上对本实用新型的一个实施例进行了详细说明，但所述内容仅为本实用新型的较佳实施例，不能被认为用于限定本实用新型的实施范围。凡依本实用新型申请范围所作的均等变化与改进等，均应仍归属于本实用新型的专利涵盖范围之内。
