PRINCIPLE OF ROLLER REDUCER

外滾柱
External rollers 出力軸銷
外殼 Output shaft pins

內滾柱 Input shaft
Internal rollers 滾柱軸承
Roller bearing
滾柱盤
Roller disc

1.圓柱型的外滾柱裝在強韌的外殼上。 1. Cylindrical external rollers mounted in robust 6.在內滾柱隨滾柱盤反時針公轉的同時，因內外滾 6.While internal rollers turning counter-clockwise

針的自轉。 of internal rollers and external rollers separately

2.圓柱型的內滾柱裝在精密的滾柱盤上。 2.Cylindrical internal rollers mounted in precision follow individual center axis due to mesh transmission.

傳動方式我們稱之為完全活齒傳動。 freely around individual center,we called this

3.當入力軸以順時針方向回轉時，帶動曲柄 3.Input shaft rotate clockwise to synchronously transmission type“innovative revolution-rotation
也做順時針回轉。 drive crank rotation clockwise. roller drive mechanism“.

8.出力軸銷隨著滾柱盤的推移，將以反時針方向作 8.Output shaft pins propelled with roller disc turn

4.透過曲柄，滾柱盤作反時針的偏心運轉。 4.Roller disc turns counter-clockwise eccentrically 公轉。與出力軸銷連結的出力軸也會做反時針方 revolution counter-clockwise; output shaft

5.內滾柱將隨滾柱盤反時針的公轉。 5.Internal rollers turn counter-clockwise accompanied 9.如圖A至圖D所示，當入力軸迴轉一圈時，內滾 9.As figure A to D, input shaft turns for one cycle,

也就等於減速比。 As a result, the number of teeth of internal rollers is

equal to the reduction ratio.
