IMPROVEMENT OF RELIABILITY OF THE IMPROVED BRUSH-COLLECTOR ASSEMBLY OF THE DC MOTOR OF THE MOBILE COMPOSITION
This article is sanctified to the problem to technical diagnostics on a public electric transport and electrical equipment. By reason of absence of methodologies of timely control of the state of brush-collector knot (BCK) and acceptance of measures on renewal of the capable of working state, about 50-60 % comes in uselessness, not working to the complete term of exploitation. Perfection of construction of BCK, development of new and improvement of existent methods of increase of reliability of exploitation of BCK, is the actual task sent to the increase of longevity and faultlessness of work of electric motors on the whole. Purpose is to develop the improved brush-collector knot of electric motors of direct-current with enhances able reliability. Methods used for creation of mathematical model and development of methodology for estimation the electric motors refuses intensity and hardware takes into account all lacks of the considered analogues and allows to carry out monitoring on refuses and disrepairs of BCK of electric motors during work on a rolling stock. Results basic reliability indexes of BCK were expected. A mathematical model is worked out for the exposure of types of refuses of brush-collector knot taking into account his technical descriptions (size of pressure, beating, amplitude of vibration) influencing on reliability indexes in the process of exploitation. The scrutinous of efficiency of functioning of improved BCK electric motors program is worked out with enhance able reliability in the process of exploitation for the extension of his time of service. Practical relevance: the offered model on the basis of research of types of refuses of brush-collector knot of electric motors is worked out the improved construction of a brush knot, that allows to increase the resource of brush and bring down expenses on technical maintenance of electric motors in the process of exploitation. Recommendations offer for passing to repair of electric motors on the actual state for a rolling stock.
