Abstract

Inventia se refera la un lagar cu role, destinat lagaruirii miscarii liniare a unui organ de masina pe o suprafata de rulare plana, în special la un lagar cu doua rînduri de role recirculabile. Lagarul cu role se sprijina pe trei suprafete ale corpului sau executat dintr-o bucata, iar pentru aliniere, astfel încît axa lor sa fie perpendiculara pe directia de deplasare, rolele gaurite axial se centreaza cu suprafetele lor frontale, pe suprafetele frontale ale canalelor de recirculare, reducerea uzurilor cauzate de frecarea rolelor între ele fiind preluata de niste colivii distantiere, iar aliniamentul rolelor, la intrarea acestora sub sarcina, unde exista pericolul cel mai mare de înclinare fata de directia de deplasare, este realizat în zonele de curbura a celor doua piese de reîntoarcere (de la capetele corpului) cu un sistem de aliniere elastic pe baza de arcuri, care apasa axial rolele de pe ambele rînduri, de la interior catre exterior, prin intermediul a doua lamele semiinelare, mentinîndu-se în permanenta cu axa perpendicular pe suprafete laterale exterioare ale canalelor de recirculare.The invention relates to a roller bearing designed for the linear movement of a car body on a flat surface, especially to a bearing with two rows of recirculable rollers. The roller bearing rests on three pieces of the body or made of a piece, and for alignment so that their axis is perpendicular to the direction of displacement, the axial bore rollers center with their front surfaces on the front surfaces of the recirculation channels , the reduction of the wear caused by the friction of the rollers between them being taken up by some distal cages and the alignment of the rollers at their entrance under the load, where there is the greatest danger of inclination to the direction of travel, is achieved in the areas of curvature of the two parts (from the ends of the body) with a spring-based elastic alignment system which axially presses the rollers on both rows from the inside to the outside by means of the two semi-lintel blades, always maintaining the axis perpendicular to external side surfaces of the recirculation channels.
