Tilting Pad Journal Bearings — Measured and Predicted Stiffness Coefficients

Abstract

This paper presents measured and calculated characteristics of a tilting pad journal bearing suitable for high speed machinery. Descriptions are given of the experimental techniques used with this variety of bearing and the theoretical model for predicting performance.

Measured values of pad temperature, eccentricity, attitude angle, and the four stiffness coefficients are given for a range of loads and rotational speeds. Data are given for both load on pad and between pad configurations, the two principal loading arrangements.

Comparisons are made between the measured and predicted bearing temperatures and stiffness coefficients over a wide range of values.
