Thermal Characteristics of Offset-Halves Bearing With Offset Factor
نویسنده
چکیده
The Reynold’s equation and energy equation has been solved using finite difference method to study the effect of variation in offset factor on the performance characteristics such as oil-film temperatures, thermal pressures, load carrying capacity, power loss, and Sommerfeld’s number of offset-halves journal bearing. Numerical solution of Energy equation is achieved using Parabolic Temperature Profile Approximation technique for faster computation. It has been observed that while keeping the radial clearance constant, an increase in offset factor results in a decrease in oil-film temperature, thermal pressure, load carrying capacity and an increase in Sommerfeld’s number. Finally, it has been concluded that the offset factor may be kept equal to 0.4 while designing offset-halves journal bearing, and should be preferred to get the desired thermal characteristics.
