Tilting pad radial bearing which features

Tilting pad usually consists of three to five or more blocks can pivot freely on the inclined curved Babbitt blocks. Tile with the speed at work can load different composite bearings and bearing temperature swing freely in the shaft diameter formed around a plurality of wedge. Each piece of tile and spherical pin through the back sliding bearing pads supported in the bearing sleeve, the tiles can be rotated about its spherical rocking support pin; bearing carved surface of the tile section, respectively, on the back of a spring-loaded, from one end of oppression tile tile, artificially established oil wedge. Lubricating oil from the gap between each tile into the bearing, is discharged from both ends of the seal ring at the opening of the bearing. If you ignore the inertia tile, friction and the fulcrum of the film within the shear force of friction, the role of each tile to film the force on the shaft diameter is always up and down through the center of only shaft diameter rotor in the bearing motion, no cause shaft diameter whirl destabilizing forces, it has high stability, it is theoretically possible to avoid the shock of film production (actual damage occurred due to bearing instability phenomenon).
    Further, since the pad can freely swing support increased flexibility, but also has the ability to absorb vibration energy of the rotating shaft, i.e., having good damping properties. Tilting pads have many advantages, but the structure is complex, difficult installation and maintenance, high cost is tilting pad deficiencies.
