Description

M406673 五、新型說明：【新型所屬之技術領域】本創作係有關一種電動缸機構，尤指一種防制螺帽轉動，同時使電動缸機構具備低噪音、高傳動效率的技術創作。【先前技術】電動缸的功能，係一種將馬達的旋轉運動經由機械元件連結轉換成直線往復運動的機構，特別是電動缸結合伺服馬達與滚珠導螺桿後，其位移精度能被精確地控制，因此電動缸已廣泛運用在自動化與精密加工的領域。圖一為習知電動缸機構，主要構件包括馬達（30)、缸體（10)、及電動桿體（20);由於電動缸是將旋轉運動轉換成直線運動，因此缸體内的機構需有螺桿及螺帽，且螺帽需有防制轉動的功能，才能將馬達帶動螺桿的螺旋進給，轉換成螺帽的直線進給，進而帶動電動桿體的精確位移。習知的電動缸，為了防制螺帽轉動，多將螺帽做成與缸體内部相同形狀，或運用方鍵將螺帽與缸體内壁連結，這種作法雖然達到防制轉動的功能，但機構間產生的高磨耗、高嗓音及低效能，連帶也影響電動缸應用於高精度產業的效益。【新型内容】鑑於電動缸的傳動方式，必須防制螺帽的轉動，才能將旋轉運動轉換成直線運動，且電動缸係應用於精密產業的製程機構，除了需達到精確位移外，低噪音與高效能也是該領域的基本需求。是以，本創作的主要目的，首要者M406673 V.
