Abstract: Mankind is capable of cognizing and handling multiple tasks at the same time. Driving is the task in which the continual combination and alternation of various basic tasks is involved. And, a number of the foresaid basic tasks need to be handled and completed simultaneously; therefore, the research looking into the parallel behavior of drivers is needed. Parallel driving has the attributes, relevance and exclusiveness, that leads to different representations according to various danger classes. In this article, the parallel driving model is put forward, and an experiment is developed to test the performance of the drivers. Through the experiments, validity of the model is verified.

Abstract: The current mechanical engineering applications require the use of increasingly larger share precision reducers and special mechatronics units with a high degree of integration. High precision gearboxes is used for such applications with low backlash and high torsional stiffness (harmonic, cycloidal or planetary). Bearing reducers (cycloidal gear) meet the requirements of small built-in space in the implementation a high-precision change of transfers. Bearing reducers TwinSpin from company Spinea accurately fulfil all of these conflicting requirements.

Abstract: The drive of the transport machine in extreme conditions should provide high reliability and durability. For this purpose the tooth gearing should have constant gearing of cogwheels. In a number of patents transmission in the form of the hydraulic converter and not switched tooth gearing is presented. However the hydraulic converter considerably complicates transfer and reduces its reliability. Transmission of extreme transport technique should have a simple design and control and to meet extreme requirements. It is expedient to use not switched adaptive tooth gearing based on a phenomenon of mechanical power adaptation. The present work is devoted working out and a theoretical substantiation of effective adaptive transmission for the transport technique working in extreme conditions.
