The dynamic processes in the device for speed control with multistage gear differential and closed-loop hydraulic systems through ring gears have been studied for case when the leading link is the sun gear of the first stage, and the driven is a carrier of the last stage. For such a device, the equation of kinetic energy has been compiled and the dynamics equations have been obtained by the Lagrange method, which have been solved. The obtained results are the basis for further computer simulation on and quantitative analysis to assess the performance of such devices and select the necessary closed-loop hydraulic systems to control speed changes.

The algorithm of practical application of researches results of speed changes management devices with a gear differential and the stopper of rotational movement in the form of the closed-loop hydraulic system has been described. An example is a single-stage single-row gear differential, when the driving link is a sun gear, driven is a ring gear, and the control link is a carrier. For such a device, the order of execution of in design steps has been described. The described execution procedure of speed change devices designing will be valid for all kinematic schemes of single- and multistage gear differentials with stoppers of rotational movement in the form of the closed-loop hydraulic systems with control through carriers.

Mine hoist shoulder important transport tasks. Through the analysis of the main circuit of mine hoist, this paper studies out ASCS digital DC speed control system whose core is microprocessor and whose hardware part constitutes digital trigger and double closed loop system. The software part not only achieves the system's digital PI regulator, logic switching, digital trigger phase shift, pulse channel selection and pulse width setting, but also realizes the systematic detection, monitoring, fault diagnosis, which improves the control precision and work stability of the system.
