Summary:	滾珠螺桿是以工具機驅動裝置之用途為主體發展起來的傳動元件,其開發的目的在於實現加工的位置精度及其順暢性。因此目前滾珠螺桿已廣泛地應用在精密機械、自動化設備、各種動力傳輸、半導體、醫療和航太等產業上，並逐漸往高精度、高速化、環保、大行程、大外徑等方向發展。滾珠螺桿是以滾珠作為螺桿與螺帽之間的動力傳輸介面,且影響滾珠螺桿的壽命較大的因素是軸向負荷，而影響軸向負荷的主因卻是取決於鋼珠與螺桿的接觸角度。當接觸角度超出設計值時，將使滾珠的運動由滾動轉為滑動，造成摩擦量增加、不順暢、溫昇，進而減少工件壽命。由於早期接觸角的測量多使用輪廓儀，該設備雖精度高但使用環境有相當高的要求，因此為使研磨加工完成的螺桿達到立即、快速而又準確的狀況下進行測量，本文使用數位投影法，以投影機、數位相機及開發的影像處理軟體結合進行線上量測，並以不同導程角進行測量再與輪廓儀比對後證實使用本方法不但可實現快速的線上量測要求，小導程精度可以達成量測上的需求，並且對於大型螺桿如外徑50mm以上，長度2500mm以上螺桿皆可量測。 Ballscrew is working as a driven device of machine tool to reinforce the manufacturing precision and smoothness. Nowadays, ballscrew is applied extensively in precision machinery, automation equipments, dynamic transmission, semi-conductors, medical treatment, aerospace, and etc; furthermore, ballscrew is developed to apply in superior precision, high speed, environmental protection, long travel and big diameter as well.Ballscrew functions as a power transfer interface between a screw shaft and a nut. Axial load which is depended on the contact angle of steel ball and screw is a major element to affect lifetime value of ballscrew. If contact angle exceeds the design value, steel ball will change its running pattern from rolling to sliding, which will cause the friction increased, bad smoothness, and temperature increased to reduce the lifetime value.Previously, the profile meter which provides high precision with superior using environment request is used for measuring contact angle. The digital projection method which integrates projectors, digital cameras, and image processing software is an efficiency and precision way to examine ballscrew. This method can achieve rapid online measurement and precision requirements for small lead angle through different contact angles measurements and comparing with the profile meter. It also can measure screw diameter over 50mm and length over 2500mm.
