On the design and development of hybrid journal bearings: a review

Abstract

This paper presents a comprehensive review of developments in the design and application of hydrostatic and hybrid journal bearing systems during the last few decades. Revolutionary changes have taken place in the applications of hydrostatic and hybrid journal bearings, from very low‐speed radar to very high‐speed turbo‐machinery and ultra‐precision machine tools requiring high stiffness to improve accuracy. Hydrostatic and hybrid bearings are of interest because of their potential at very high operating speed and heavy load‐carrying capacity. This paper also outlines the analyses done of these types of journal bearings in practical application, which has led to improved bearing design. This review critically discusses the parameters that significantly affect the static and dynamic performance of a journal bearing. This review includes coverage of recent publications in the literature pertaining to hydrostatic and hybrid journal bearings focusing on the influence of parameters such as bearing geometry, supply pressure, flow control devices, fluid compressibility, fluid inertia, journal misalignment, bearing flexibility, surface roughness, and thermal effects.

Analysis of Vessel Sliding Bearing Wearing Characteristics and Contact Angle

“…The technical measures of reducing temperature of bushing surface may improve the bearing capacity of large-scale bearing, such as radius of supporting plate, collaborative support system and cooling bearing bush. In 2006, H.C.Grag [5] summarized the research progress of dynamic and static pressure sliding bearing. In their opinion, they shall research the influence of axis deflection, bearing deformation, surface roughness, non-newtonian feature of lubricant and thermal effect on bearing performance.…”

Multiple Alignment Stage for the Automatic Precision Alignment System

“…All kinds of electronic components is becoming more sophisticated. Therefore, the components in the manufacturing process more stringent precision requirements for the repeated positioning [1] on the process, the use of artificial means is waste time and resource for human and will be unable to meet the needs of the industry. Machine supervised the production system with control mechanisms, the convenience factor of digital image to obtain an increased and improved image quality.…”

Investigations in Hydrostatic Planar Bearings Compensated by Tapered-Spool Restrictors II: Load Capacity and Static Stiffness

“…Although many articles have studied in this topic, almost all their investigations in relationships between compensation devices and hydrostatic bearing are constrained on specific design. Garg [4] presented about hybrid and hydrostatic bearings, sixteen articles were cited for the studies in the influences of restrictors on the performances of hydrostatic bearings. Then Bassani [5] made some modification for the opposed-pad and coplanar-pad bearings with the usages of cylindrical-spool and tapered-spool valves, cylindrical-spool and tapered-spool dividers, and common fixed compensators.…”
