Rosoha S. Computer and geometrical models of rotor-planetary trochaics gidromashin

Object - shaping working structures of rotor-planetary hydromachines which form is defined by the attitude separatorys radiuses of circles of mechanisms; the purpose - creation of computer - technological bases of calculations of parameters of elements of rotor-planetary hydromachines on the basis of a complex of computer - geometrical models which define forms and working volumes of cylindrical and cone-screw versions of these machines, and the decision of a problem of a choice of their rational geometrical parameters on the basis of modern achievements of applied and computing geometry, computer schedules in the field of analytical representation of curves and surfaces of complex technical forms; methods - methods of analytical, applied, differential, computing geometry, the theory of curves and surfaces, methods of applied programming, computer schedules, discrete applied geometry; theoretical and practical results - are developed theoretical bases and methods of construction of geometrical models of surfaces which limit working volumes of rotor-planetary hydromachines and take into account features of mutual interface of mobile and their immovable parts, a way of calculation of a tooth gearing of internal gearing of arch type which enters into a design of the rotor-planetary mechanism and their geometrical and computer modelling is carried out; scientific novelty - the description bypass families of the curves formed in result running by the planetary mechanism epitrochoid or hypotrochoid for the first time is carried out; for the first time classification of family of structures of rotors and cases trochoid machines is offered, depending on the attitude of radiuses pitch circles of the planetary mechanism for cylindrical and cone-screw constructive registration; for the first time the original way of calculation of the area of a figure between structures of a rotor and the case is developed; for the first time the analytical device of the description of internal gear gearing of arch type for the rotor-planetary mechanism is received, depending on their working contours; for the first time definition of dynamic characteristics of the machine of rotor-planetary type with the asynchronous electric motor is carried out; a degree of introduction - the sumy machine-building research-and-production association by him is introduced on Open Society ". М.В. Frunze ", Joint-Stock Company "Kherson oil refining factory ", the municipal enterprise of sewer facilities "Kharkovcomunotcistvod" within the framework of a state budgetary research theme " Geometrical modelling of working volumes rotor-planetary trochoid hydromachines " and in educational process of University of civil protection of Ukraine and National technical university " Kharkov polytechnical institute"; sphere of use - structural divisions of scientific research institute and design office which carry out calculations of hydromachines and are engaged in designing of new "rotor-planetary" technics.
