EFFECT OF MOUNT ANGLE ON STATIC AND DYNAMIC CHARACTERISTICS OF GAS-LUBRICATED, NONCIRCULAR JOURNAL BEARINGS.

In the case of noncircular journal bearings, as opposed to circular journal bearings, the orientation of bearing with respect to a given load direction can be a design parameter. This orientation may be defined in tenus of an angle, which in the present work is being referred to as the mount angle . The purpose of the work presented in this paper is to study the effect of the mount angle on the theoretical static and dynamic characteristics of three types of gas-lubricated noncircular bearings. It is found that the effect of the mount angle happens to be more pronounced at low compressibility numbers. Also, among the three types of bearings, the effect of the mount angle is more significant in two lobe bearings in comparison to the three and four lobe bearings.
