Abstract

An ultra-precision part called an aerostatic bearing uses a spindle that is encircled by a thin layer of air. The demand for aerostatic bearings in the electronic, instrumentation, healthcare, and other manufacturing or processing industries is extremely high owing to their high accuracy. The primary area of attention in this work is the experimental determination of the impact of the roughness parameter on the functionality of the thrust and journal bearings. The aerostatic bearing is created based on the theoretical study to accomplish the goal. The present design is examined numerically using ANSYS Fluent’s computational fluid dynamics module to simulate airflow. The pressure distribution results of earlier studies confirm the result of simulation. The manufactured components are assembled to analyse the variation in radial and axial loads acting on the spindle with the spindle displacement (1–5 µm) in the direction of the load at supply pressures (3–6 bar) in the clearance of 30 µm after performing the finishing on the bearing and spindle surface. Three different methods—machining, grinding, and magnetorheological finishing—are employed to improve the surface of the air bearing. The variance in axial and radial loads acting on the spindle for each roughness reduction technique is calculated using the variation in spindle displacement. According to the experimental findings, the increase in load capacity for journal bearing and thrust bearing at a 5 µm spindle displacement is determined for machining to grinding and for grinding to magnetorheological finishing, respectively. The surface finish parameter’s results show how surface roughness affects the aerostatic journal’s and thrust bearing’s ability to carry loads. For applications like drives in industrial machinery, where better surface finish is a crucial aspect in raising overall functional efficiency, the current study on aerostatic bearing surface finishing is useful.
