27-80 ÎNCERCAREA DE COMPRESIUNE A BILELOR DE RULMENT


THE COMPRESION TEST OF THE BEARING BALLS
The compression test of the bearing balls is not included in the category of classic methods this is regulated by normative like (STAS or ISO). They appear as a necessity where developed and manufactured various kinds of bearings. In this perspective the paper presents the concept of a specialized device for applying a compressive force to the bearing balls of different sizes, and some half-ball.
This makes it possible experimental research of the state of stress and strain that occurs in ball bearing in compression during operation using various methods like: electric resistive strain and/or photo elasticity (fotostress).
