Abstract

Procedeul, conform inventiei, consta în pretensionarea barelor de colivie printr-o operatie de deformare elastica în sens centripet, utilizînd un dispozitiv de strîngere cu colier cilindric metalic care se aseaza pe o banda elastica nemetalica, dupa care se monteaza în fiecare interval dintre doua capete de bara de colivie cîte o piesa de distanta si niste folie de aliaj pentru lipit, urmata de rigidizare prin împanarea cu una sau mai multe piese de distanta a extremitatii de colivie, urmata de montarea unui al doilea dispozitiv de strîngere, se procedeaza apoi la întoarcerea rotorului din pozitia orizontala în care au fost executate operatii de strunjire în pozitie verticala, în scopul introducerii extremitatii coliviei într-un canal strunjit frontal într-un inel de scurtcircuitare avînd o geometrie identica cu geometria extremitatii de colivie...The process according to the invention consists in pre-stressing the cage bars by means of a centripetal elastic deformation operation using a metal cylindrical clamping device which is placed on a non-metallic elastic band and then mounted in each intersection between two ends the cage bar with a piece of distance and an alloy foil for soldering, followed by stiffening by tightening one or more cage-end spacing pieces, followed by the mounting of a second clamping device, then proceeding to the return the rotor in the horizontal position in which vertical turning operations were executed for the purpose of inserting the cage's extremity into a frontal turned channel in a short-circuit ring having a geometry identical to the cage-shaped geometry ...
