Abstract

Inventia se refera la un dispozitiv de rectificat cu actionare electrica si turatie mare, destinat prelucrarii alezajelor cu diametru redus,în special, masini de rectificat interior; format din arbore rotitor, pe care se afla rotorul motorului electric, sustinut în rulmenti radiali axiali, la care statorul motorului electric este montat în carcasa exterioara, prin intermediul unei bucse intermediare avînd la exterior un canal elicolidal prin care circula fluidul de racire. Dispozitivul este prevazut cu un butuc interior de rezemare posterioara a unui arbore rotitor ale carei deplasari axiale sînt preluate de butucul interior prin intermediul unei bucse cu bile, ghidata pe alezajul unei carcase exterioare, rezemarea axiala a butucului interior fiind asigurata de niste arcuri elicoidale.
