摘要

軸承應用起源於搬運物品，物品放置於滾動之樞軸上使其前進，演變至今，對於軸承之應用廣泛出現於生活上，應用包括：螺絲、引擎主軸之軸心，普遍應用其做為一轉動機件，因此，轉動之軸心其真圓重要性關係於所產生之效果與導致的後果。量測手法區分接觸量測與非接觸量測，接觸性量測必須與待測物接觸，容易導致待測物被破壞與污染，例如：游標卡尺。而非接觸性量測特性使用非接觸性方式量測待測物，而且精確範圍符合要求，例如：雷射測距儀。本實驗設計一簡易軸承之軸心量測平台，運用非接觸量測手法，搭配一特殊平台，結合設計電腦控制之量測程式，控制整體量測平台，完成由進入至輸出可由電腦控制完成之軸心量測。本實驗設計ㄧ由雙長軸所構成之傾斜平台，由馬達驅動的雙長軸使待測物前進，待測物由高處往低處移動時經過ㄧ凹槽，雷射量測光束掃描經過凹槽的待測物獲得待測物尺寸。本實驗設計一控制量測程式，經由串列埠擷取回量測尺寸並進行處理。並使用DAQ擷取卡接收平台上的感應器訊號與控制閥門訊號。結合上述運用非接觸方式量測軸承軸心尺寸量測，改善原有量測不易問題。

Applications of bearings originate from carrying articles. Articles are put on the pivot rolling to make it advance. Until today, applications of bearings are broad, including：screw、engine main shaft, etc. In daily life, the most common use is to rotate parts around an axis, which is a part of the bearing. Therefore, a precise circularity of the rotating axis is very important which relates to the effect and the consequence. Data acquisition method can be classified into non-contact method and tactile method. Using tactile method, one must contact the object being measured. Therefore, the object can be easily contaminated or destroyed (e.g. caliper). Using non-contact method, one doesn’t have to contact the object. The range of precision is more likely to meet the need (e.g. laser scan meter). In this thesis, the experimental design is a sloped platform with one pair of major axes. This pair of major axes is driven by motor to make objects advance. When objects move from higher to lower through a fillister, laser light beam scans the test pattern from fillister and measures diameter of axes. The experimental design includes a control and measuring software. Through the serial port, an automated control software is designed to capture signals from a laser scan instrument and obtain measured diameters. In addition, signals are received from sensors and processed by the control software to control the electromagnetic gates using a DAQ card. Combing the non-contact method above, a precise axis diameter is measured, thus solve the original measuring problem.
