The Visualization of an Air Flow in the Clearance of an Externally Pressurized Thrust Gas Bearing by the Heat Curing Oil Film Method (The effect of the oleic acid on the rheological characteristics of the heat curing oil without hardener and titanium dioxide)

Abstract

The heat curing oil film method using thermosetting property oil film is a new oil film method. The heat curing oil film method, in which not only the plane flow pattern in wall surface but also oil film thickness of the steady flow can be measured, is newly developed. The heat curing oil film method is a very useful method for visualization of an air flow in the clearance of an externally pressurized gas-lubricated circular thrust bearing with a central supply hole. The rheological characteristics and the effect of the oleic acid on the rheological characteristics of the heat curing oil without hardener and titanium dioxide are investigated in this paper.
