Parametric investigations of short length hydro-dynamically lubricated conical journal bearing
Gangrade, Ajay K1, Phalle, Vikas M2, Mantha, S.S3.
Due to the growing need for compact size fluid film
bearings, efforts are being made to explore the
performance of hydro-dynamically lubricated short
length conical journal bearing. The combined radial and
axial load carrying features of these bearings emerge as a
better option to replace the two separate bearings
(journal and thrust pad bearings) employed in turbomachines and other applications. Thus, in this study,
attempts have been made to investigate the performance
of conical hydrodynamic journal bearing by using finite
element analysis. The bearings have been investigated for
semi-cone angle (γ = 10°), aspect ratio (λ = 0.5, 0.8, 1.0),
journal speed (v = 2.6, 5.2 m/s) and load variations in
terms of eccentricity ratio (ε) up to 0.6. Results have been
presented in terms of radial and axial load carrying
capacity, stiffness coefficients, damping coefficients and
threshold speed. Results from the present study reveal
that load carrying capacity is improved with higher aspect
ratio; whereas threshold speed decreases with the
increase of eccentricity ratio and aspect ratio.
