&nbsp;&nbsp;</span><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">先简要介绍轨迹球的组成和工作原理。轨迹球组件由一只滚动球，两片摩擦轮，两根旋转轴，两片析光轮<span style="max-width: 100%; font-family: &#39;Times New Roman&#39;; box-sizing: border-box !important; word-wrap: break-word !important;">(</span>光栅轮<span style="max-width: 100%; font-family: &#39;Times New Roman&#39;; box-sizing: border-box !important; word-wrap: break-word !important;">)</span>，四队对应的红外发光二极管和光敏接收管以及处理芯片组成。</span></p><p style="max-width: 100%; min-height: 1em; text-align: justify; box-sizing: border-box !important; word-wrap: break-word !important;"><span style="max-width: 100%;

word-wrap: break-word !important;">它的工作原理于机械鼠标类似，即依靠滚动球的滚动摩擦带动横向和纵向的旋转轴转动，转轴在带动固定在其上的光栅一起转动。通过光栅的旋转使光敏二极管在接收发光二极管发出的光时被阻隔、空开，而产生计数脉冲，经芯片处理后在屏幕上显示出来。</span></p><section class="" data-source="bj.96weixin.com" style="max-width: 100%;

&nbsp;&nbsp;</span><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">观察彩超的轨迹球部分，发现球体表面污迹很多，周围缝隙处也有不少耦合剂残余。初步判断是风干的耦合剂附着了污物造成上述问题。</span></p><p style="max-width: 100%; min-height: 1em; text-align: justify; box-sizing: border-box !important; word-wrap: break-word !important;"><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">&nbsp;&nbsp;&nbsp;&nbsp;</span><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">打开按键板外壳，取下轨迹球组件并拆开。看到轨迹球盒内的两根转轴上均裹有一个海绵做的摩擦轮，经过多年的摩擦，不少海绵碎屑与耦合剂积灰洒落在盒中，两片析光轮周围布满了杂质，导致光脉冲信号的传输受阻或减弱，影响了轨迹球的使用。</span></p><p style="max-width: 100%; min-height: 1em; text-align: justify; box-sizing: border-box !important; word-wrap: break-word !important;"><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">&nbsp;&nbsp;&nbsp;&nbsp;</span><span style="max-width: 100%; font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">处理方法即，先用吹风球轻轻吹出盒内杂质，再用棉签蘸纯酒精小心地擦去发光二极管和光敏接收管表面的积灰。对滚球则先用清水清洗，再用擦擦克林对其进行擦拭，最后用棉布擦干。要注意的是，最好不要用洗洁精等化学品来清洁滚球，以免造成滚球表面的腐蚀。</span></p><p style="max-width: 100%;

font-family: 宋体; box-sizing: border-box !important; word-wrap: break-word !important;">处理好后还原组件，不盖上盖，用手向各个方向拨动滚球，使光栅转动。感觉析光轮在左右方向上转动不畅。于是用干性电子清洁剂清洁，等干后加入少量润滑脂，使它能顺畅的转动。值得注意的是最好不要用润滑油，以免吸附灰尘。最后将组件装回机器，彩超均工作正常，故障排除。</span></p><p style="max-width: 100%;
