Speed ​​change principle of control mechanism of MB stepless speed changer

　　MB stepless speed changer or reducer, which is installed on a mechanical device to achieve speed change. MB stepless speed changer is a kind of more commonly used speed changer, which has the characteristics of large speed range, high speed adjustment accuracy and strong composition ability. The speed change principle and composition structure of MB stepless speed changer, the following is a detailed introduction to the speed control mechanism of speed control mechanism:

　　Rotate the hand wheel to drive the speed control cam to change the angular position, fix the cam curve surface, make the speed control cam move axially, change the distance between the speed control cam and the fixed ring, and move the friction wheel radially to uniformly change the planetary wheel and the driving wheel. , The working radius of the pressure plate and the fixed ring, the cam friction place, realizes the stable stepless speed change.
