An article presenting the results of joint research with Kinki University was published in the April 2024 issue of "Monthly Tribology."

We are conducting joint research with Kinki University on "static pressure gas bearings (non-contact bearings)" that use "air" as a lubricating fluid, which can be used even in clean environments compared to oil. Static pressure gas bearings can support rotating shafts non-contact by supplying compressed air from the outside, thereby reducing the generation of wear particles from manufacturing machinery's rotating shafts and bearings.
In this study, we developed a method to analyze flow rates and the restoring force of the shaft through CAE analysis by rotating the shaft using two types of bearings: axial type (jointly developed / made of resin) and circumferential type (conventional) slot throttling static pressure gas bearings. The developed CAE analysis method enables a significant reduction in the number of experiments needed to understand the phenomena of static pressure gas bearings during shaft rotation.
We aim to apply the results of this research to the practical design of static pressure gas bearings, contributing to the enhancement of cleanliness and longevity of manufacturing machinery, such as food production lines, thereby reducing maintenance burdens.
