PERFORMANCE OF FULL TEXTURED HYBRID THRUST BEARING BY CONSIDERING THE TEMPERATURE VARIATION IN OIL FILM

The heat generated by the bearing surface is carried away by lubricant and bearing part. a major part of the heat generated in the lubricating film during operation is transferred to the bearing components. Friction coefficient in the fluid film bearings is directly proportional to the frictional power consumption. The frictional power loss in the bearings results in rise of the lubricant oil temperature which may ultimately lead to failure of the bearing. This leads to increase in the temperature of bearing pad. In 1974, Huebner[1] studied the thermohydrodynmic sector shaped thrust bearing. He proved that thermohydrodynmic solution can be used to analyse the fluid film pressure and other performance parameters accurately. Brockett et al.[2] studied the effect of mechanical deformation as well as thermal deformation. They found that the effect of thermal deformation on the temperature of thrust bearing is major whereas the effect of mechanical deformation on temperature is very small.
