Double thrust ball bearing detail

The double thrust ball bearing is installed in the double thrust ball bearing of the front bearing seat, and its function is to bear the axial thrust of the rotor and determine and maintain the correct axial position of the rotor.  
Along the horizontal split bearing shell, solid even on, between the second half of the bolts and a taper pin positioning, bearing shell in a former and the double thrust ball bearing of the bearing pedestal between shell and support with the dowel had to prevent the shell axial rotation.  

Each double thrust ball bearing has two groups of thrust rings, and each group has eight fan-shaped thrust tiles. The inner and outer arcs of the tiles are matched with the grooves of the shell so that the tiles can be positioned in the radial direction, and the tiles are positioned in the circumferential direction by the circular pillar pins.  
Double thrust ball bearing are dynamic pressure bearings. To make the bearings work normally, the following conditions should be met:  
1.  The lubricating oil has a viscosity;  
2.  There is a certain relative velocity between moving and stationary bodies;  
3.  Two surfaces in relative motion inclined to form an oil wedge;  
4.  The external load is within the prescribed range;  
5.  Enough oil.  

Pay attention to the preceding requirements during installation and operation.Tile bearing double thrust ball bearing is michelle type, each segment of the working face casting plastic metal layer, bearing alloy layer thickness of 2.0 mm, there is a deviation on the back of tile symmetric center bearing steel as a result, under the action of a hydraulic tile around the bearing steel swing tilt, thus formed between thrust disc and thrust segment cuneate gap, when the rotor rotates.
