Abstract
When performing technological processes, it becomes necessary to control changes in speed in magnitude and direction. Today, special attention is paid to the method of controlling speed changes using single-stage and multistage differential gears with a closed hydraulic system. Relevant issue is the efficiency of such devices. The aim of the work is to obtain analytical and graphical dependences of the efficiency between the driving and the driven links in single-stage single-row and two-row differential gears with closed hydraulic system, when the driving link is the carrier, and the driven one is the epicycle, and vice versa. The work of a single-row and two-row differential gear was analyzed in cases where the driving link is the carrier, and the driven one is the epicycle, and vice versa. The control link of the speed change is a solar gear that can rotate when fluid is pumped in the hydraulic system, or can be stopped by a closed hydraulic system. An analytical study of the efficiency for such a transmission was performed, and its graphic dependencies on transmission parameters were obtained. Based on the obtained analytical expressions and graphical dependencies, a conclusion was made about the change in the value of the efficiency from the ratio, the speed of the control link, and its estimation from the point of view of self-braking was performed.
