Abstract
The paper shows theoretically the influence of elastic deformation of a long bearing on the squeeze action of a full oil-lubricated journal bearing. Thick liners and those with a thickness radius ratio of 0–2 (Poisson's ratio of 0–4) are considered at constant load. For a given dimensionless load value a decrease in the peak pressure is predicted, together with increases in the eccentricity ratio and minimum film thickness. The time to squeeze from the centre of the bearing to a given film thickness is also increased.
Next, a thick bearing and shaft, or bearing alone, are considered at constant squeeze rate, and at a given value of dimensionless load a decrease in peak pressure, an increase in eccentricity ratio, and an unaltered value of minimum film thickness are predicted.
