Abstract

用于检测旋转钢轴1位置的系统，包括一个涡流电流传感器2，和一个固定于轴上并行经该传感器下的导道3，该导道由一绝缘带4构成，带上具有高导电率非铁磁材料围绕该轴有规则分布的多个区域，该系统的特点是带4以其具有非铁磁材料区域的表面粘结到该轴1上。系统较为简单而能获得较高幅值的信号。

Description

本发明涉及检测一个钢旋转轴的位置的系统，该系统包括有一个涡流电流传感器和一个固定到所述轴上并行经该传感器的导道，该导道包括有能被该传感器感测到的多个间断点。
已知的导道包括有在轴的外圆周上形成的多个几何图形间断点（孔、凹槽、栓柱）。
但是加工这些间断点的费用是很贵的。
还已知DE-A-3，109，586专利采用了一种固定到转轴上的导道，该导道由一条绝缘带构成，绝缘带上具有由高导电率非铁磁材料多个区，各区环绕该轴有规律地分布。
在这种先有技术的系统中，这些非铁磁材料区设置在所述绝缘带上背向着转轴。
本发明人发现，把这些非铁磁材料区面向着转轴来设置，也即，把这些区域尽量靠近该钢轴设置，信号能增强。
此外，该绝缘带还能保护这些非铁磁材料区。
本发明还涉及在钢转轴上制造具有非铁磁材料区的导道的制造方法。制作规则地分布着非铁磁材料区的带子并使这些非铁磁材料区面向着钢轴地将带子粘结在轴上。
通过对下述附图所作的描述，将对本发明会有更清楚的了解：
图1示出本发明的一个检测系统;
图2示出适合制作本发明带子的一种带状物;
图3示出粘结在轴上的图2所示的导道;
图4为铜和钢存在情况下涡流电流传感器的响应曲线图。
参照图1，检测钢轴1位置的检测系统包括：一个涡流电流传感器2和一个行径该传感器的导道3，该导道由带子4构成，该带子上设置有非铁磁材料（最好用铜）的多块矩形区5，这些区围绕轴1均匀分布。
带子4是由0.3毫米厚的层压式环氧树脂介质制作的，其上沉积一层70微米厚的铜。为了只保留下多个铜区域5，用电腐蚀的方法将铜层的一些部分腐蚀掉。
将带子4粘结到轴1上，使区域5其毗邻于该轴。粘结剂6应选择得能使带子4在离心力和切向力方面获得良好的机械性能。采用环氧树脂粘结剂，能适应于该轴的工作环境（水、油、温度）。
各铜区域5受到片压层4的保护。
图4分别示出当应用钢（A）和铜（Cu）时，从涡流电流传感器的输出端上得到的电压，并描绘为该电压相对于金属与传感器之间距离e的函数。可看出铜的响应曲线明显地高于钢的响应曲线。由于各铜区域很靠近钢，所以可认为它们与该传感器的距离基本相同，因此，当各铜区域行经传感器时，产生较大的电压差。
由常规的装置7检测出这些电压差，从而检测出轴1的位置。应用该信号能具体地量测出轴的角度和/或轴的速度。
