description |
This paper investigates the effect of
bearing shell elastic deformation on the
steady state behavior of misaligned journal
bearings. Performance trends of elastic and
rigid bearings with different degree of
misalignment (Dm) have been compared.
Bearing shell elastic deformation, thermal
effects, pressure and temperature variation
for a bearing working under turbulent
lubrication have been taken into
consideration. It is found that misaligned
bearings working at higher misalignment
coefficients have higher load carrying
capacity since the oil film thickness
approaches to zero in this case. Considering
the effect of bearing shell elastic deformation
with the effect of oil film temperature causes
lower values of bearing load. Some of the
results obtained in this paper have been
compared with that published by other
workers and found to be in a good
agreement.
