高精度 -- 複節距蝸桿蝸輪與三片式離合齒 --
HIGH ACCURACY - Dual Lead Worm Gear System and 3 Pieces of Hirth Coupling Gear

採用「複節距蝸桿蝸輪組」,傳動精確、背隙調整容易,配合三片式平面離合齒定位,分割精度高達±4弧秒以內,重現精度更可達±1弧秒以內,經長時間的使用仍能維持其高精密度。最小分割角度1∘和5∘適用於高負荷的精密定位切削。

Built with accurate “Dual lead worm gear system,” backlash can be adjusted easily, keeping high accuracy even after long term using. With Three Pieces of Hirth Coupling Gear positioning, the index accuracy is within ±4 arc second and Repetitive accuracy ±1. Minimum Index Unit Degree is 1° and 5°, suitable for accurate and heavy duty orientate cutting.

耐重切削 -- 油壓三片式離合齒鎖緊裝置 --
HEAVY DUTY CUTTING TOLERATION - Three Pieces of Hirth Coupling Gear clamping system

分割台內部使用三片式平面離合齒,執行角度分割時盤面沒有升降動作,再加上紮實的密封結構,在大量的切削液的使用場所,也不會讓粉屑和切削液滲入本體內。超強的剛性機構及夾持力,在重切削時能大大的發揮效果。

With Three Pieces of Hirth Coupling Gear built inside, there is no floating action during degree indexing, and whole-closed structure design can keep dust and cutting fluid out from the body even if much cutting fluid is used. High rigidity and gripping force increase the efficiency greatly during heavy duty cutting.

動作說明 -- 三片式平面離合齒裝置之主要結構 --
DIRECTION - Structure of Three Pieces of Hirth Coupling Gear

如下圖所示,三片式離合齒裝置之主要結構共分三部分:A離合齒(鎖固在轉盤結構上) ,B離合齒(鎖固在分割台基座結構上),C離合齒(上下動作之托板)

Referring to the figure below, the structure of three pieces of hirth coupling gear is divided into three parts: Gear plate A (locked on the rotation plate), Gear plate B (locked and fixed on index table bottom), Gear plate C (up and down action board)

  • 如圖b所示,C離合齒下降時,分割台即成為鬆開狀態,A離合齒由結構緊密的支撐著,所以轉盤在沒有升降動作情形下,精確且順暢的旋轉。

    (Figure b) When Hirth Coupling Gear C descends, the index table is unclamping. With Gear plate A supported, the rotation plate rotates smoothly and accurately without vertical moving error.

  • 當A離合齒 (轉盤) 完成分割定位時,C離合齒往上動作並與A離合齒和B離合齒完全契合,形成高精確度的一體結構。

    (Figure a) When Gear plate A completes indexing, Gear plate C goes up to match Gear plate A and B, clamping the index table.

  • C離合齒有足夠的寬度與A離合齒和B離合齒完美契合,離合齒盤各齒的壓力角30°,精確的將A離合齒和B離合齒對準,經長時間使用後,精度一樣地準確。

    Gear plate C has sufficient face width to matche Gear plate A and B completely, ensuring high accuracy even after long-term using. (The pressure angle of each gear is 30°.)
