Trouble Shooting of Deadlock of MuIti-tile Hydrodynamic LubricationBearing Combination and Its ResearchXU Gui.1an.ZHA0 Li-ping.JIA0 Xiao-ming(Shaanxi Polytechnic Institute，Xianyang 712000，China)Abstract：For three-tile hydrodynamic lubrication bearing combination with the diferent performance，this paper analyzes its struc。

ture，technical requirements and assembly process and solves the problems such as ovemize temperature rise of coolant oil dunngunloaded running or deadlock of spindle in debugging.A simple and efeive method is provided for the products of similar struc。

tures，meanwhile this shows that the cooperation of using peformance，part manufacturing and assembly process is very impodant。
