Ringcone Variable RCV Series
|
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.
