Non-contacting Suspension Support Travelling Body Using Negative Pressure of Externally Pressurized Thrust Gas Bearing

Abstract

The complicated phenomena such as pressure depressions, shock waves and the negative pressure, are detected in the air flow with a large bearing clearance or high supply pressure in an externally pressurized gas-lubricated circular thrust bearing. The pressure depression, which decreases the bearing load carrying capacity, is an undesirable phenomenon occurring in this gas bearing. The non-contacting suspension support travelling body using negative pressure of the externally pressurized thrust gas bearing is proposed in this paper. The non-contacting wall surface travel body has been composed of an externally pressurized gas-lubricated thrust bearing and the jet mechanism. The travel body which can run wall surface (ceiling and vertical wall) in the non-contacting condition has been done.
