“…In [1], the theoretical effectiveness formulas for the two-stage differential gear transmission were obtained and verified by experimental studies. The design of a bi-planetary transmission was presented in [2], with the calculations of the kinematics, statics and efficiency of gearing. Omitted from the calculation are the geometry and strength of gears, shafts and rolling bearings, as these are recognized as being typical design calculations.…”

The energy effectiveness of the multistage gear differential in the device for speed change by carrier has been investigated with the determination of the efficiency. Considering complexity of the problem, the analytical methods of efficiency determining for two-and three-stage differential gears have been obtained and proposed using the potential power method, when the driving link is the first-stage sun gear, the driven link is the ring gear of the last stage or vice versa, and the links of the speed change control are the carriers of the individual stages. With the help of computer modeling of analytical expressions, graphical dependences of efficiency from the ratio of the multistage differential gear and the angular velocity of the control link-the carrier, have been obtained. The results obtained have practical application for the design of new devices by means of energy effectiveness, allow to evaluate the operation of multistage differential gears from the point of view of self-breaking and are of assistance for further research.

Purpose. Theoretical and computer research and determination of performance efficiency of three and fourstage gear dif ferentials in speed changing devices through sun gears. Substantiation of the possibility of their use in machine drives based on estimating their energy efficiency and possible selfbraking. methodology. To solve this problem, we used the method of "potential power"; by computer simulation, analytical expressions for the performance efficiency are obtained; using the MS Excel software package, the graphical dependencies of energy efficiency on the gear ratio, the angular velocity of the sun gear and the number of stages are obtained. findings. The obtained graphic dependences for the performance efficiency of three and fourstage gears differentials allow one to follow visually the change in the value of the efficiency, depending on the angular velocity of the sun gear, the gear ratio and the number of steps. This allows us to estimate the perfection of the given differentials in terms of energy consumption and possible selfbraking. originality. For the first time, analytical expressions were obtained for a more precise determination of the efficiency of a three and fourstage differential gears with a driving carrier and a driven ring gear, or vice versa. Obtained from the analytical formulas, graphic dependences for the performance efficiency allow one to follow the change in the value of the performance efficiency. Practical value. It is recommended for implementation in designing and constructing practice when developing the speed change devices through the differential transmissions of drives of various machines. It can be used in the educational process of technical higher educational establishments in mechanical engineering disciplines in the study of machines drives.
