Thermal Error Analysis of Spindle Based on Temperature-Deformation Model

Thermal behavior of an improved face-grinding spindle: water-lubricated hydrostatic thrust bearing decreases temperature rise and increases axial stiffness

“…Until now, there has been an increasing amount of literature on thermal analysis of machine tool spindle system. The research objects mainly include spindles supported by rolling bearings [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], spindles supported by hydrostatic bearings [20][21][22][23][24][25], and spindles supported by hydrodynamic bearings [26,27]. Modeling methods adopted mainly include: finite difference method [5,6], thermal resistance network method [3,4,7,16], bond graph method [18,19], and finite element method [8-15, 17, 20, 23-27].…”

“…Modeling methods adopted mainly include: finite difference method [5,6], thermal resistance network method [3,4,7,16], bond graph method [18,19], and finite element method [8-15, 17, 20, 23-27]. In their studies, temperature distribution and thermal deformation were calculated using the above methods [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][22][23][24][25][26][27]. Experimental research includes two aspects: one is measuring temperature rise of spindles by temperature sensors or thermal imagers [3, 4, 7-18, 20, 21, 23, 25-28]; another is measuring thermal deformation using displacement sensors [8-18, 20, 22, 24-26, 28].…”
