Abstract

Inventia se refera la un stand pentru determinarea influentei miscarii parazite de spin asupra tractiunii elastohidrodinamice. Standul, conform inventiei, în scopul obtinerii a doua contacte cu tractiune aproape identice, foloseste doua discuri coaxiale dintre care unul este conducator si celalalt condus, între care se afla o bila de rulment deplasabila radial fata de discurile ce sunt apasate unul spre altul, discul conducator fiind antrenat de la un motor electric printr-o cutie de viteze, iar cel condus fiind fixat la capatul unui arbore sprijinit pe niste rulmenti, prevazut la extremitatea inferioara cu un disc de aluminiu ce formeaza împreuna cu doi electromagneti de curent continuu o frîna cu curenti turbionari ce poate regla si masura momentul de frînare, pentru aflarea alunecarii longitudinale din contact folosindu-se traductoare electromagnetice de proximitate conectate la frecventmetre digitale.The invention relates to a stand for determining the influence of spin parasitic motion on elastohydrodynamic traction. According to the invention, the stand, in order to obtain two almost identical traction contacts, uses two coaxial discs, one of which is the driver and the other one, between which there is a bearing ball radially displaceable relative to the discs which are pressed against one another, the driver being driven from an electric motor through a gearbox and the driven one being fixed at the end of a shaft supported on some bearings, provided at the bottom with an aluminum disc that forms together with two DC electromagnets a brake with swirling currents that can adjust and measure the braking moment to detect longitudinal contact slippage using proximity electromagnetic transducers connected to digital frequency meters.
