Gear Reducer with Variable Series
RCGH	RCGV	RCHW

Features

Large speed regulating range; High reduction ratio︰

The speed shifting mechanism with speed shifting ratio 1:6 at 4P60Hz can serve 200-1200 rpm and even down to 1 rpm while going with speed reducer.

Reliable performance and high loading capability︰

Special precision structure provides high resistance to impact loading and reverse loading in addition to high efficient operation and easy maintenance.

Operation notices：

1.Do not regulate the speed under stop conditions.

2.For full loading condition, please regulate to low speed and restart.

3.Avoid overload operation.

游星輪(8)固定於游星輪支架(13)而繞太陽(5)(6)旋轉，游星輪被左右(5)(6)太陽輪利用平板彈簧緊密夾住，同時亦被外環(7)及凸輪(9)所夾住，當動力由入力軸(3)傳入(6)左太陽輪，游星輪除了自轉以外，亦繞著太陽輪軸心轉動，動力經游星輪支架(13)支架本體(16)而至輸出軸。

速度變換︰

速度調整係經由調速軸(11)轉動時移動凸輪，力用凸輪(15.9)來調整橫向間隙(△l)，當間隙增加或減少時可改變游星輪之位置(如上圖)而改變速度。

The principle of stepless speed shifting machine Input shaft connects to cone disc and then rotates the flange disc. By turning the hand wheel, the center point of the cone disc shall be moved from A to B as shown in the figure. The contact diameter ratio of cone disc to flange disc as well as the rotation speed of circular ring are subject to the position of cone disc by means of worm driving along with circular ring. By this principle. effective speed shifting ratio can reach 1:10.	Revolution R.P.M	4P	6P
