Abstract

Inventia se refera la o cama pentru comanda ventilelor unei masini cu piston de ridicat, destinata pentru consumul ventilului în conlucrare cu un cap de alunecare cu baza, plata, cu învingerea fortei elastice a unui arc de contact. Cama are o geometrie a portiunii sale de vîrf critica pentru pelicule de ungere, ce asigura formarea hidrodinamica a unei pelicule portante. Geometria se calculeaza într-un mod prezentat în descriere, iar ca urmare a aplicarii inventiei se reduce frecarea, ceea ce determina sporirea durabilitatii. Obiectivul inventiei se utilizeaza, în special, în domeniul constructiei de masini.
