Dynamic characteristics of wide tapered‐land slider bearings

Abstract

Taking into account squeezing‐action effects, the present study is concerned with the dynamic characteristics of a tapered‐land slider bearing with infinite width. According to the results obtained, the bearing characteristics are significantly affected by the shoulder parameter δ and the geometric parameter α of tapered‐land bearings. For a fixed α, there exist some δ such that the bearing possesses a maximum load, a minimum friction parameter and a maximum stiffness. Compared to the plane‐bearing case, the tapered‐land bearing produces higher damping coefficients, and provides higher load capacity and dynamic stiffness at large α. These results provide useful information for engineers in selecting and designing bearing systems.

Key words:

• slider bearing
• tapered‐land shape
• stiffness coefficients
• damping coefficients
