bearings are one of the machine elements that function to reduce friction that
occurs in machine components. Journal bearings are commonly used in industry
and power plants because they are capable of working at high shaft rotation and
large loads. This research focuses on the effect of providing a surface texture
with rectangular geometry on the performance produced using water lubricants.
The flow of lubricant in the journal bearing is greatly influenced by the
condition of the surface texture provided. These conditions will give different
results to the journal bearing performance parameters. Several parameters are
analyzed as performance comparisons, namely the value of load carrying capacity
(load capacity), friction force (friction force), and acoustic power level
(noise). These parameters were generated using the Ansys Fluent 3D simulation
model. This research shows the differences in the values of the resulting
performance parameters. Providing a rectangular texture has the same effect on
lubrication as water fluid. The presence of a rectangular texture has been able
to increase the load carrying capacity value but also increases noise emissions
and friction force values. This research shows the conclusion that not all
parameters of journal performance can be improved as a whole and produce the
opposite consequences.
