Description
Technical field
The present invention relates to technical field of bearings, be specifically related to a kind of new flexible hinge tilting-pad bearing.
Background technology
Hydrodynamic sliding bearing utilizes the viscous effect of the relative motion between friction pair and fluid, is brought into by working fluid
Wedge gap thus form dynamic pressure bearing capacity.Along with the raising of rotary speed, dynamic pressure effect is further obvious, and therefore, dynamic pressure is slided
Bearing is widely used in high speed, high-precision rotary equipment；It is multiple that static-pressure sliding bearing is dependent on being distributed on bearing circumference
Static pressure chamber carries, and bearing capacity is higher.And tilting-pad bearing belongs to the one of hydrodynamic sliding bearing, if it uses circumferentially
Dry tile fragment is as load-carrying unit, and each tile fragment is evenly distributed, and forms dynamic pressure oil film, produce dynamic pressure between each tile fragment and main shaft
Pressure field, in order to the load in supports main shaft.When the shaft core position of main shaft changes because load changes, tilting-pad bearing
Tile fragment can rotate around fulcrum, to adapt to the change of load, tilting-pad bearing also has that noise is low, friction power loss simultaneously
The advantages such as little, good stability.But, tilting-pad bearing is compared to tradition static-pressure sliding bearing, and bearing capacity is relatively low；Meanwhile, at height
In speed operation process, tile fragment swings many, it is likely that tile fragment leading edge and rotating shaft generation wiping can be caused to touch and cause bearing failure；Again
Secondary, owing to traditional sliding bearing running accuracy is uncontrollable, in high-precision rotation main shaft application, carried by the cycle
Under the effect of lotus, this uncontrollability becomes apparent from.
Because above reason, the present invention proposes a kind of flexible hinge tilting bush sliding bearing containing Static prestressed-pile oil pocket
Device, by controlling the pressure of this static-pressure oil chamber, improves the bearing capacity of main shaft, resistance to shock and running accuracy.
