Optimal Heating Time for Cylindrical Items Removal from the Shaf
Journal Title: ANALELE UNIVERSITATII DIN CRAIOVA - Seria Inginerie electrica - Year 2015, Vol 39, Issue 39
Abstract
For easy removal of cylindrical items from the shaft, they are heated on their external cylindrical surface for thermal dilatation. The best result is obtained if the temperatures gradient inside the item is highest on the separation surface. In the paper, considering a suddenly occurring constant high temperature on the external cylindrical surface of the homogeneous item, the shaft with the same thermal diffusivity and neglecting the contact thermal resistance, the transitory thermal field is analyzed and optimal time for item removal is determined. Example is given.
