ABSTRACT
One of the components used to hold the shaft transmitting power and rotation is
journal bearing. Journal bearing has the advantage of being able to withstand
large loads and high rotation, however, journal bearing has a weakness, which is
high friction. This high friction is minimized by means of lubrication, where the
lubricant forms a film layer which functions as a separator between the journal
and the housing so that mechanical contact does not occur. Journal bearing
usually work with dynamic loads on their operation, these dynamic loads affect
the thickness of the film layer and the hydrodynamic pressure on the journal
bearing. The approach with the finite difference method is one method to
determine the thickness of the film layer and the hydrodynamic pressure on
journal bearing due to dynamic loads. The finite difference method is used to
solve the differential equations in the dynamic load bearing Reynolds journal
equation. The dynamic load acting on the journal bearing is the influence of nondimensional
amplitude and non-dimensional frequency. The non-dimensional
amplitude was varied from 0.1 to 0.5, while the non-dimensional frequency was
varied π / 4, π / 2, π, 2π, 4π, and the observed time was 0.00 s to 0.09 s The
conclusion is that the load on the journal bearing is directly proportional to the
hydrodynamic pressure and inversely proportional to the thickness of the film
layer with a maximum hydrodynamic pressure of 3,313 kPa and a minimum film
layer of 32.92 μm, and the load of the journal bearing is directly proportional to
the eccentricity ratio. The maximum eccentricity ratio is 0.675. Meanwhile, nondimensional
amplitude affects hydrodynamic pressure and non-dimensional
frequency affects changes in hydrodynamic pressure with time.
