Object of research: unproductive power losses in transmissions for want of modular principle of construction EMM and loading machines.Purpose of research: improving of main technological performances is block - modular EMM and loading machines with the help of improvement of a structure and choice of rational parameters of transmission. Method of research: the use of the theory of a similarity and elements of the Boolean algebra has allowed in a theoretical part to develop a technique of construction typesized consistency of power modules EMM and loading machines; the search of a minimum and maximum of the developed with the help of theory of a similarity dimensionless functions of the indicated moment of inertia and mass of cog-wheels has allowed to increase efficiency transmission at the expense of a diminution of losses on dispersal and braking of gyratings of masses; methods of an electrical measurement of mechanical magnitudes; statistical methods of processing of experimental researches. Equipme nt: strain metrical station for a measurement of performances of the modular frontal loader, computer engineering. Theoretical and practical outcomes: new scientific outcomes extend submission about processes, which happen in transmission of machines for earthen and road work, the outcomes of a conducted research can be used for want of designing transmissions of base machines of earth-moving and loading engineering offered techniques of construction typesized consistency of a of transmissions can find application for want of to development of power modules of earth-moving and loading engineering. Novelty of new implementation: is, that influence of the scheme and parameters of transmission on technological parameters EMM for the first time is determined and loading machine efficiency (dynamic efficiency - power losses on dispersal and braking of gyratings of masses) for want of is block - modular a principle of their construction with allowance for dynamic component, for the first time are obtained and the d imensionless performances of a mass and indicated moment of inertia of transmission are optimized. Degree of application: At the Kharkov Tractor Factory,at the Kharkov Factory the Tractor Automotive Chassis, in Association "Ukrtractor", at the Industrial Association "Carpatagromash" is introduced. Area of usage: earth-moving and road construction machines.
