Analysis of moments of burden of single roller table has performance of setting dependence in arrangement: motor - reducer - roller table. Dependence this have onto real detailed cycles for size of parameter A and m in roller table driving arrangement. Cycles of loads showing courses change of strengths of reaction in prop of rampart rolls and arrangement of forwarding element on rolls of forwarding line. Analysis of loads roller table gives basis to analytic delimitation of real moments of burdens, how special meaning has also for technique of protections and staminas calculations.

The load of both metallurgical roller table and statically incalculable multi-span beams can be determined in the same way. The choice of appropriate basic scheme and application of special form of forces' method, known as "three moments' method", simplifies solving this problem. Designation of load function for metallurgical roller table is significant at both planning mechanical strength of the table and choice of driving motor power. Formulating the mathematical models of driving systems with specially designed induction motor and considering real load function in these models is important to determine the design directives during realization of this type of driving systems under real operating conditions

Need of control of speeds and rotatory moment in driving system results from technological regards and economies of energy. Search of suitable models for electromechanical systems joins with designing of electric motors, exploational methods as well as prognostic solutions for present driving arrangements. Modelling of driving systems, which include in their construction the roller tables, permits onto introduction of supplementary measures for opinion of efficiency for analysed arrangement, this is: partial performance and total, coefficients of economy of electric energy, etc. The practical aspect of investigation of driving arrangements it can be selection of optimum parameters of driving system.

This article presents adaptation of mathematical model in a view of real, asymmetrical load that occurs in roller table line. Present descriptions of load torque of electromechanical systems were equivalent to the usage of load torque as their indicators to nominal torque of driving engine. The analytical description of torque based on my analysis of load, would allow the introduction of mathematical, real course model of the load substituting those of indicators. On the basis of conducted research of simulated dynamical states by means of MATLAB/SIMULINK program, I received courses of equivalent parameters having direct influence on the complete load in a system that occurs in a single table roller, in a set of rollers or in a driving system. This article shows only selected courses of electromechanical driving system because of very extensive mathematical and IT methods necessary to conduct an anticipatory analysis.

Analiza momentów obciążenia pojedynczej rolki samotoku ma na celu przedstawienie zależności jakie zachodzą w zespole rolki samotokowej, które mają wpływ na cykle rzeczywiste szczegółowe dla wielkości parametru A i m w samotokowym układzie: silnik-reduktor-rolka samotokowa. Cykle obciążeń są zatem przebiegami odzwierciedlającymi zmianę sił reakcji w podporze wału rolki uwzględniając położenie elementu transportowego na rolkach linii transportowej. Analiza obciążeń samotoku daje podstawę do analitycznego wyznaczenia rzeczywistych momentów obciążeń, jak również ma szczególne znaczenie dla techniki zabezpieczeń i obliczeń wytrzymałościowych.
