Abstract

Hydrostatic bearing is a key part that provides precision and long life to machine tools. It is one of the embodiments of tribology, mechanics, optimization method, and structural design in enginee...

Highlights

This review considers more than 400 articles published from 1990 to 2016
Researches from the United States account for 25% which is leading the studies of hydrostatic bearings
Among the articles dealing with rectangular oil pad, most focus was on dynamic characteristics of the bearing (31%) and surface texture (25%), followed by studies on bearing modeling (12%), error analysis (13%), and optimization design (19%) (Figure 27)

Summary

Introduction

This review considers more than 400 articles published from 1990 to 2016. Among them, researches from the United States account for 25% which is leading the studies of hydrostatic bearings. Some researchers tried to introrical coordinates, and many scholars calculated the duce different types of surface textures to improve its pressure distribution and load-carrying capacity of it supporting performance because a flat bearing surface is easy to be machined. The bearing modeling or its improvement (32%) and surface texture introduction (31%) are distributed almost ; other researches refer to bearing optimization and the study of dynamic characteristics (Figure 13).
