THE STUDIES OF THERMOELASTIC CONTACT FOR DETERMINATION THE FIELDS OF TEMPERATURES AND THERMAL TENSIONS IN BEARINGS INNERS (STATIONAR REGIM)

Abstract

Classical elastic contact stress theory concerns bodies whose temperature is uniform. Variation in temperature within the bodies may, of itself, give rise to thermal stresses but may also change the contact conditions through thermal distortion of their surface profile. The skill of machines tools is based in very large measure on the reliability of the bearings. The numerical methods permit to solve the thermal tensions problems. In the study is presented the temperature distributions in a conducting half -space, the result of the utilized of the finite element method for study the temperatures and the thermal tensions in inners bearings. The system is compound by inner acting by concentrated. Source of temperature is applied on the inner.
