Some basic characteristics of planetary gear trains and their application on high-speed tracked vehicles

The definition, classification and designation of elements of planetary gear trains were carried out and their basic characteristics were given in the indefinitely baby opi paper the bases of kinematics of planetary gear trains were presented and possibilities of lock-up modes were analyzed from the special aspect of power circulation.The analysis of basic parameters of planetary gearboxes of some contemporary high speed tracked bang xxl switch duo vehicles was performed and the kinematics schemes of gearboxes were shown.The basic elements of methodology for the creation of optimal kinematics scheme of compound planetary gear trains were described and the obtained optimal solution of the kinematic scheme was analyzed.
