QUESTION TEN
A journal bearing has to be designed to support a radial load of 1280 N which is placed on a shaft of
96 mm diameter. The shaft rotates at 1800 rpm and its eccentricity is 0.038 mm . The desired temperature
rise of the lubricant is to be 10\deg C. As the bearing will be well cooled, it may be assumed that 70% of the
heat generated will be convected by the oil.
Design the bearing by determining its performance characteristics if the following parameters are given:
L=0.102;c=5.1\times 10^(-5)m;\mu =4.1\times 10^(-2)Nsm^(-2); Specific heat =1800(J)/(K)g^(0)C; density =880K(g)/(m^(3))
