Abstract
Inventia se refra la un procedeu de centrare dinamica exterioara a motoarelor si generatoarelor electrice de diametru si puteri mari, care au rotorul si statorul pe reazeme diferite, caracterizat prin aceea ca, în scopul uniformizarii fortelor electromagnetice din întrefierul masinii si pentru eliminarea fortelor mecamice suplimentare din lagare care apar numai în timpul functionarii masinii electrice, se face calibrarea mecanica a sistemului masina electrica-traductoare-reazeme, considerat rigidizat, cu ajutorul a doua aparate indicatoare, dupa care se alimenteaza motorul si se masoara fortele pe directia pe care se doreste anularea solicitarilor în lagar, se citesc derivatiile aparatelor indicatoare, care sunt unul în sens pozitiv si celalalt în sens negativ, dupa care, fie cu alimentarea mentinuta cuplata, fie decuplata, se misca pe directia de montare a traductoarelor, fie rotorul, die statorul masinii, în sensul maririi întrefierului dinspre aparatul cu indicatie în minus, pâna la obtinerea indicatiei de zero la ambele aparate.The invention relies on a method of centering the external dynamics of motors and generators of diameter and high powers having the rotor and the stator on different supports, characterized in that in order to uniformize the electromagnetic forces in the car air gap and to eliminate the additional mechamic forces bearings occurring only during the operation of the electric car, the mechanical calibration of the electrical machine-transducer-support system is considered rigid with the help of two indicator devices, after which the motor is fed and the forces are measured in the direction in which the requests are canceled in the bearing, the derivatives of the signaling devices, which are positive and the negative ones, are read, after which either the coupled or disengaged supply is moved in the direction of the transducer mounting, either the rotor, the machine die, in the the sense of increasing the air gap from the minus sign until you get the zero indication on both devices.
