ABSTRACT
Contact between the roller element with the inner or outer ring produces
enormous pressure which can cause friction between the surfaces of the two
objects. The continuous friction will result in wear and using lubricant between
the two contacting surfaces becomes an important role to reduce friction as well
as wear. There are several types of lubrication, one of them is elastohydrodinamic
lubrication. In this study the numerical method of Finite Difference Method is
used to solve Reynolds equation in order to investigate the effect of basic
parameters such as initial load, surface speed and radius of the cylindrical roller
bearing. A single contact of cylinder roller and inner ring is modeled as a contact
between a solid cylinder and flat plate. The influence of temperature, nonnewtonian
fluids and dynamic loads are ignored in this research. Centraldifference
scheme in the Finite Element Method is used to solve the Reynolds
equation for calculating the elastohydrodynamic pressure that occurs on a
contact. The results obtained show that there is an influence of the initial load,
velocity and also the radius of the pressure generated at the time of contact
between the solid cylindrical bearing element and the thickness of the film layer
formed between the two surfaces of the object. The greater load given will
increase the maximum pressure, but reduce the minimum film thickness. While
when given variations in velocity, increasing the minimum value of film thickness
and reduce the maximum pressure. Similarly, increasing the minimum value of
film thickness and reducing the value of maximum pressure.
