Design of pocket elliptical bearings

What is it about?

The purpose of this paper was to conceive a fast method to verify design and performance of elliptical pocket journal bearings. The computer-aided verification of pocket journal bearings is performed by means of a suitable finite element analysis method. The results of sample analyses indicate that the machining tolerances are very influential on elliptical pocket bearing performances, and they must be included among the input data.

Why is it important?

Although elliptical pocket bearings are widely used in turbomachineries, the influence of their design on performance has not been specifically investigated. A lot of works about tribological models are available, but few of them focus on their application to bearing design at the industrial level.
