Abstract
In this paper kinematic analysis of differential transmission gear box is presented. In the differential transmission gear box input power is transmitted by two ways. First way is so called direct or primary way and other way is secondary or parallel way. Essential parts of the differential transmission gear box are input and output or mixed planetary gear. In the parallel way a variable rear is placed. Dependence of the resultant gear ratio on variable gear ratio is determined and graphically shown.Keywords: differential, planetary gear, sun wheel, satellites, ring gear, planet carrier
