Study On Lubrication Performance Of Titling-pad Thrust Bearing

Lubrication calculation and experimental design of thrust bearings are the basis of design and manufacture,and are the basis for predicting bearing performance and ensuring their safe operation.Generally speaking,the existence of static pressure injection ports can be neglected for the convenience of modeling.It is found that ignoring the existence of static pressure injection ports when predicting large-sized fan-shaped thrust bearings often leads to deviations in calculation results.The main research is on the influence of static pressure oil injection port structure,bearing point position and tile deflection on bearing lubrication performance.In this paper,the mathematical model of the thrust bearing can be established firstly,and the boundary conditions of each equation are given and the dimensionless work of each equation is completed.Secondly,In this paper,the thrust bearing with static pressure oil filling port is taken as the research object,and the mathematical model suitable for simulating the oil film lubrication of the tilting pad thrust bearing is constructed,and it is written in FORTRAN90 language Calculation program.Finally,the influence of static pressure injection port with different parameters on the lubrication performance is obtained by simulation.The influence of different depths of oil filling port and different diameter oil filling ports on lubrication performance was analyzed.The influence of the position of the bearing point and the deflection of the tile on the lubrication performance of the bearing is analyzed.The accuracy of the calculation program is verified by comparing the calculated results of the achievable thrust bearing established in this paper with the experimentally measured results.
