转动手轮带动调速凸轮改变角向位置的同时，调速凸轮的端面曲线经平面弹子夹和固定凸轮的端面曲线作用，使调速凸轮产生轴向移动，从而均匀改变调速凸轮和固定环之间的间隔，使锥度行星摩擦轮产生径向移动。最后均匀地改变了行星摩擦轮与主动轮、压盘及固定环、调速凸轮摩擦处的工作半径，实现稳定的无级变速。
The continuously variable transmission mainly consists of a compressed driving wheel device, a friction transmission mechanism, and a speed control mechanism. The MB series planetary friction mechanical continuously variable transmission mainly consists of a compressed active device, a friction transmission mechanism, and a speed control mechanism. The tapered driving wheel and pressure plate are compressed by a set of disc springs, and the input shaft is keyed to the driving wheel to form a compressed driving device. A set of planetary friction wheels with taper are sandwiched on the inner side between the compressed driving wheel and the pressure plate, and on the outer side between the fixed ring with taper and the speed control cam, forming a friction pair; When the compressed active device operates, the friction wheel performs pure rolling. Due to the fixed ring and speed control cam not moving, the friction wheel rotates while rotating, and drives the planetary carrier to rotate through the central axis and slider bearings of the planetary friction wheel.

The principle of continuously variable transmission:
While rotating the handwheel to drive the speed control cam to change its angular position, the end face curve of the speed control cam is subjected to the action of the plane spring clamp and the end face curve of the fixed cam, causing the speed control cam to move axially, thereby uniformly changing the spacing between the speed control cam and the fixed ring, and causing the tapered planetary friction wheel to move radially. Finally, the working radius at the friction point between the planetary friction wheel and the driving wheel, pressure plate and fixed ring, and speed control cam was uniformly changed to achieve stable and continuously variable speed.
