Abstract

Inventia se refera la o îmbinare filetata, solicitata într-o directie axiala, constînd din doua piese ale caror axe coincid si care au coeficinti sensibili diferiti de dilatatie termica liniara, una din piese fiind o piesa filetata exterior si cealalta piesa fiind filetata interior. Este prevazuta o conicitate ce are o valoare astfel încît, la temepratura ambinata, variatia jocului radial pe unitatea de lungime dintre fileturile opuse de lungime ale fiecarei piese este data de expresia A delta T tg.fi, în care: - A = diferenta coeficientilor de dilatatie termica liniara a materialelor din care sînt confectionate piesele în directia axiala; -deltaT = temperatura de exploatare a îmbinarii, minus temperatura ambianta; - fi = unghiul ascutit format din fateta solicitata a filetului fiecarei piese sau axele. Jocul radial creste în directia aplicarii solicitarii piesei care are cel mai mare coeficient de dilatare termica liniara. Se utilizeaza în industria constructiilor de masini.
