Journal bearing design using TKSolver

Hirani H., Athre K., Biswas S.

Applied Mechanics and Engineering

1999

Vol. 4, no spec.

39-44

An easili adaptable design for journal bearing is furnished as an improvement over bearing design evaluated by trial and error method using many design charts. Guidelines are arranged to decide bearing length, clearance and bearing materials. Simplified closed form algebraic expressions are used to reduce computational time and cost for the prediction of maximum pressure, fluid film temperature rise, quantity of lubricant, friction loss, load zapacity and whirl onset velocity. Automatic iterative solving feature of TKSolver software is applied to extract eccentricity for a given load. The results of load, maximum pressure, friction loss, maximum temperature and attitude angle are given in tabular form over a range of eccentricity ratio to optimize bearing design.
