V packaging steel strip stepless variable speed principle of variable speed drive

V packing steel belt CVT transmission principle of variable speed V steel belt CVT transmission device in the variable speed, the distance between the main, driven wheel shaft remains the same, the Lord, the movement of the driven pulley cone plate relative to the fixed cone plate for mobile, mobile zahn movement usually rely on hydraulic equipment complete, when active wheeled mobile cone plate near the fixed cone plate, the movement of the driven pulley zahn is accordingly to leave the direction of fixed cone plate. This move will make the v-shaped steel strip for the overall translation, change the main, driven pulley and V steel belt of the contact friction circle diameter, active belt wheel transmission radius increase, driven belt wheel transmission radius decreases, and thus transmission ratio decreases. Conversely, when the movement of the driven pulley cone plate near the fixed cone plate, active wheeled mobile zahn is accordingly to leave fixed zahn direction, transmission ratio will be bigger. Because of the Lord, driven belt wheel transmission radius dimension can be continuous variation within a certain scope, therefore, the device can realize stepless variable speed drive transmission ratio continuous change.
