Description

一种利用空气压缩机轴向传感器调整间隙结构 技术领域
本实用新型涉及空气压缩机技术领域，尤其涉及一种空气压缩机轴向传感器检测与检测板之间的距离来调整转子轴向位置的结构。
背景技术
空气压缩机轴向传感器检测与检测板之间的距离来调整轴向位置的结构。包括转子、轴向传感器、检测板、叶轮和叶轮压紧螺栓。
现有的空气压缩机对于轴向检测位置不够准确，结构不够紧凑，所以不便于人们使用。
发明内容
本实用新型的目的是为了解决现有空气压缩机对于轴向检测位置不够准确，结构不够紧凑，不便于人们使用的缺点，而提出的利用空气压缩机轴向传感器调整间隙结构。
为了实现上述目的，本实用新型采用了如下技术方案：
一种利用空气压缩机轴向传感器调整间隙结构，包括叶轮，所述叶轮的一侧连接有检测板，所述叶轮的一侧设有转子，转子与叶轮相互靠近的一侧设有两个对称设置的轴向传感器，轴向传感器的左边设有一个检测板。
优选的，本实用新型的叶轮为圆台形状。
优选的，本实用新型转子的一端开设有螺纹孔，螺纹孔与叶轮压紧螺栓螺纹连接。
本实用新型中，具体安装如图所示。原来的结构叶轮底部是没有检测板的，一般都是把轴向传感器放在转子端部检测来调整间隙，现在检测板安装在叶轮的底部，轴向传感器通过检测与检测板之间的距离来调整间隙。这样使轴向检测位置更加准确，使结构更紧凑，减小了机器的占用空间。
本实用新型结构简单，使用方便，能够使轴向检测位置更加准确，使结构更紧凑，减小了机器的占用空间，满足了人们所使用的需求。
附图说明
图1为本实用新型提出的利用空气压缩机轴向传感器调整间隙结构的结构示意图；
图中：1叶轮、2检测板、3转子、4叶轮压紧螺栓、5螺纹孔、6轴向传感器。
具体实施方式
下面将结合本实用新型实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。
参照图1，利用空气压缩机轴向传感器调整间隙结构，包括叶轮1，叶轮1的一侧连接有检测板2，叶轮1的一侧设有转子3，转子3与叶轮1相互靠近的一侧设有两个对称设置的轴向传感器6，轴向传感器6左边设有一个检测板2。
本实用新型中，叶轮1为圆台形状。
本实用新型中，转子3的一端开设有螺纹孔5，螺纹孔5与叶轮 压紧螺栓4螺纹连接。
本实用新型中，具体安装如图所示。原来的结构叶轮1底部是没有检测板2的，一般都是把轴向传感器4放在转子端部检测来调整间隙，现在检测板2安装在叶轮1的底部，轴向传感器3通过检测与检测板2之间的距离来调整转子轴向位置。这样使轴向检测3位置更加准确，使结构更紧凑，减小了机器的占用空间，满足了人们所使用的需求。
以上所述，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。
