Abstract
The stable and balanced operation of the air spindle requires an extremely precise manufacturing process. Therefore, it is very important to calculate the dynamics, pressure distribution and stiffness in designing. There are many methods to calculate the air bearing pad model between shaft and bearing in the air spindle. In this paper, a very easy understanding and implementing calculation method which is air-electric equivalent for air bearings of five degrees of freedom was introduced, thereby, the relationship between stiffness, clearance and pressure distribution on air bearing pad surface was realized. Based on this calculation result, it is possible to propose a suitable design and manufacturing method in production conditions in Vietnam.
