Understanding Journal Bearings - EDGE
Understanding Journal BearingsMalcolm E. Leader, Machinery Dynamics , ColoradoABSTRACTThis paper covers the basic aspects of Journal Bearings including lubrication, design and application. Descriptions ofvarious types of Journal Bearings are presented. Guidance is given for choosing the proper bearing type and keeping yourbearings healthy. A section on do s and don ts gives practical are used to prevent friction between parts during relative movement. In machinery they fall into two primarycategories: anti-friction or rolling element Bearings and hydrodynamic Journal Bearings . The primary function of abearing is to carry load between a rotor and the case with as little wear as possible.
The primary advantage of a fluid film bearing is often thought of as the lack of contact between rotating parts and thus, infinite life. In a pure sense, this is true, but other complications make this a secondary reason for using these bearings. ... hydrodynamic loads imposed on the bearing surface by relative shaft-to-bearing vibration. Some ...
