Abstract

Inventia se refera la un procedeu de realizare a unei bride elastice pentru fixarea unei sine pe un suport, înaintea supunerii la operatia de calire si de tratament termic; capetele care coopereaza cu suportul si cu piciorul sinei sunt îndoite unele catre celalalte în aceeasi directie opusa fetei de închidere, care apare în stare de functionare, cînd brida este gata neîncarcata, capetele fiind aduse într-o pozitie unele peste celalalte la o anumita distanta, iar dupa tratamentul termic, brida este supusa la o miscare continua prin presare sau lovire pentru deformare permanenta o data sau de mai multe ori, în aceeasi directie sau în directie opusa directiei de actionare a fortei de actiune pe timpul lucrului, astfel încît dupa o deformare continua ca aceasta, tensionarea bridei nu va creste sau va creste foarte putin, brida venind dupa fiecare deformare, în acest fel bridei i se imprima de fiecare data o asemenea deformatie permanenta încît, dupa deplasarea în continuare a capetelor unele fata de celalalte, ordinul de marime al cresterii fortei care actioneaza asupra acestor capete este mai mic decît 1/6 din cresterea initiala a fortei respective, deci înaintea operatiunilor de calire si de tratament termic...
