The main objective of the present work to perform thermal analysis on the deep grove ball bearing for different materials to enhance the thermal performance, for that three dimensional CAD model of deep groove ball bearing of 110 mm outer diameter, 70 mm inner diameter of rolling balls diameter of 9.525 mm with 12 balls have been used to perform thermal analysis for the stainless steel, high carbon chromium steel, metal matrix (Ti-6Al-4 V-12TiC), GCr15 steel, silicon nitride (Si3N4) and Zirconium dioxide (ZrO2). Results show that heat flux in chromium steel is 4.3% more than stainless steel, titanium ally 25.34% more than chromium steel, CCr15 63.015% more than titanium alloy, metal matrix (Ti-6Al-4 V-12TiC) 28.97% more than GCr15 steel and zirconium dioxide & silicon nitride gives 1.57 times more than metal matrix and other materials. It has been also observed that zirconium dioxide & silicon nitride gives 6.07 times total heat flux more than stainless steel, 5.78 times more than chromium steel, 4.41 times more than titanium alloy, 2.32 times more than CCr15 and 1.57 times more than metal matrix. Hence zirconium dioxide & silicon nitride have better thermal performance. |
