Theoretical Investigations Into Plain Bearings with Gap Geometry Under Dynamic Load 700718

The development of reliable plain bearings requires a great deal of preliminary information about their working conditions. Even though theories of dynamically loaded bearings have had significant success in design application, some doubt remains as to whether bearing reliability calculated in this way can be accepted with confidence. This paper introduces theoretical methods of applying to plain bearing calculations the shaft displacement curves derived from hydrodynamic principles, which take into consideration the effects of axial grooves and arbitrary gap geometries. The calculations presented here show that these measured displacement curves are more closely related to design reliability requirements for full journal bearings with circular gap geometries.
