Abstract: As temperature increases the viscosity of the heavy machine hydrostatic turntable oil film decreases, resulting in the decrease in the bearing capacity of the table. Therefore, temperature is an important factor affecting the speed and bearing capacity of the turntable. The Reynolds equation considering the centrifugal force and the convection dominated energy equations are simultaneously established in polar coordinates. Finite difference method is applied to establish the relationship between temperature distribution and bearing capacity of the hydrostatic turntable under different speed. The established model is verified in a 5 meter vertical lathe hydrostatic bearing test rig. The results show the oil temperature increases with the rotation speed of the table; when the speed reaches 40r/min, the temperature rises rapidly and the bearing capacity decreases sharply. The oil gasket seal edge temperature rise is different, in the high speed side the temperature rise is more obvious, resulting in local high temperature region. This study may provide reference for further analysis of thermal compensation and structural design optimization of hydrostatic turntable.

Key words: mechanical design, temperature field, heavy machine hydrostatic rotary table, rotating speed, bearing capacity
