Tilting pad radial sliding bearing which features
The destabilizing force of the radial vortex, therefore, has high stability and can theoretically avoid the occurrence of the oil film shock (in fact, due to the damage of the bearings)In addition, the pad can swing freely and increase the support flexibility, also has the ability to absorb the shaft vibration energy and vibration damping is very good. The tilting pad has many advantages, but the complex structure, installation and maintenance more difficult, the cost is higher. The shortcomings of tilting padAlso, any questions, please continue to discuss with me
The lubricating oil from the gap between each pad into the bearing, from both ends of seal bearing ring hole discharge. If you ignore the effect of pad inertia, friction force and the oil film shearing force of internal friction fulcrum, each pad to the axial diameter of the oil film force is always through the center shaft, the rotor movement in bearings only, will not have a leading axis
Composition of tilting pad usually consists of 3 ~ 5 arc Babbitt pad or more blocks can freely tilt on the fulcrum of the pad. When working with speed, load and bearing temperature of free swing, forming a plurality of wedge in diameter around. Each piece of tile is supported on the bearing sleeve through the back the ball pin and pad, pad can be around the spherical support pin swing; surface upper pad, the back bearing are respectively arranged in the spring, from the end of the pad pad compression, artificial establishment of oil wedge.
