Analysis of Multi-Grooves Water Lubricated Rubber Alloy Bearing Considering the Elastohydrodynamic Lubrication

  • The elastohydrodynamic lubrication mathematical model, considering the multi-grooves effect and actual boundary conditions, was implemented in order to accurately analyze the influences of the multi-grooves and its arc radius on the lubrication performance of the water lubricated rubber alloy bearing. The results show that the grooves had significant effect on the pressure and film thickness distributions, the value of the pressure was opposite with the value of the film thickness, and the distributions was corresponding to the grooves geometric distribution in the circumferential direction. Besides, peak pressures were produced nearby the axial inlet and outlet respectively where the minimal film thickness occurred. In addition, the pressure, load capacity and film thickness decreased due to the increase of the groove radius. However, the load-bearing capacity increased with the increase of the eccentricity. The friction coefficient increased with the increase of the rotate speed or groove radius.
