The article presents a new design of the drive which includes chain and toothed developed geometric and kinematic calculations. Feature of chain gears is that the sprocket pins have involute profile. The drive has a high load capacity, higher kinematic accuracy with reduced dynamic loads
Total lie is considered in the article as strategic information weapons of society in the era of globalization and augmented reality. The article reveals the possibility of application the principle of observability in modern society, as it is common in physics criterion of reality. It is shown, in which cases the application of this principle in studies of society leads to social illusions, and when it gives adequate results. We have offered a concept: “the degree of virtualization of society” and a quantitative scale for its measurement, and we have also introduced the concept of "Public Umwelt" by which the area of society that differs significantly from the rest of their fundamental laws is meant
In this article we present a study of current problems connected with the formation of a park of automobiles, tractors and aggregates for transportation of agricultural products and ways of
their solution
The article reviews the current state of plant waste disposal. Also presents directions of development of composite materials of this type of stuff
The results of tribological researches on influence of friction on contact interaction of tobacco leaves with working bodies of the machines for their harvesting and further green leaf processing are presented. Coefficients of static and sliding friction are measured
The analysis of heat and mass transfer in the wall-adjacent jet of gas under essential non-isothermal conditions is given. The calculated relations of chemi-cal erosion intensity of surface on the basis of integral correlation for the turbulent boundary layer are ob-tained. The presented calculations are successfully compared with the experimental results
The turbulent movement of the liquid with dispersed phase in the channels of thin layer clarifiers and hydrocyclones is reviewed. The evaluation of the dimensions of the particles, which are taken by the turbulent pulsation is performed. The turbulent sedimentation of the fine phase is researched as a type of a process of diffusion. Using the equations from the theory of mass transfer and the edge of the turbulent level, the coefficients of the speed of the transfer of the particles are acquired. The results of the calculations, covering the effectiveness of the turbulent separation are provided, with the use of the models of perfect mixing and displacement
The power plant being investigated is Novocherkassk
State District Power Plant located in the settlement of
Donskoy, Rostov region. The power object is included
in the list of objects of the fuel and energy complex
subject to categorization and is defined as critically
important. The analyzed site is the "subsidiary farm",
which includes a chemical reagent warehouse and a
site for chemical water purification, where hazardous
substances are treated: sulfuric acid and technical
sodium hydroxide. The analysis of the main causes of
accidents at thermal power stations occurred during
processing, storage and transportation of hazardous
substances, and typical scenarios of possible accidents
at the chemical water treatment plant of thermal power
plants were considered
The results of development of the experimental stand for studying of ultradisperse heterogeneous systems in time are represented. The possibilities for registration of the experimental factors of refraction which allows to obtain the data about system granulometric structure are submitted
The article presents the analysis of mobile crushers, improved chopper equipped with spreader disk with blades positioned on the frame, as well as experiments to optimize the parameters of the vortex sprayer
