Operating temperatures of the bearing system of grinder spindle
Journal Title: Tribologia - Year 2011, Vol 236, Issue 2
Abstract
The ground for the safe operation of multilobe journal bearings at proper oil film temperature is the full knowledge of bearing thermal performances particularly the oil film temperature distribution and its maximum value. This paper describes the theoretical and experimental investigation into the operating temperatures of pericycloid, 3-lobe journal bearings supporting the spindle of grinding machine. The oil film pressure, temperature and viscosity fields have been obtained by iterative solution of the Reynolds', energy and viscosity equations. Adiabatic, laminar oil film and the static equilibrium position of the journal were assumed. Experimental investigation consisted in the measurements of temperatures in the bearings.<br/><br/>
