Description
Technical field
The present invention relates to a kind of nano-milled shaft technical field, more particularly to a kind of high pressure nano-milled for dry type
Air-flotation type grinds shaft.
Background technology
It is existing it is nano-milled mainly use wet grinding because the particle diameter very little of the powder of 300 mesh, with extruding and cutting
Method, can not achieve further crushing, so realizing that nanoscale is ground using the wet grinding for adding fluidity medium, complete to grind
Need that abrasive is dried after mill, for organic materials, drying process brings heavy damage to its character.Dry type nanometer
Grinding, it is necessary to kinetic energy collision is carried out to realize that nanoscale is crushed using powder and crash panel, thus there are three big technical bottlenecks,
Firstth, the axis to run at high speed, the second highly tight sealing bearing, the 3rd, high rigidity crash panel.The shaft to run at high speed can be by
High power motor is realized, but shaft and bearing friction produce superhigh temperature, cause shaft bending to deform, make it is nano-milled cannot be real
It is existing.High pressure draught can drive powder to enter bearing through nanoscale gap in nano-milled tank, meanwhile, axis can with bearing wear bits
Powder is caused to pollute.Although composite polycrystal-diamond has the hardness of diamond, but light weight, the energy of carrying is small, it is difficult to real
Existing energetic encounter.
The present invention is using axle center, axle sleeve, the combining structure high pressure gas floating axle center of axle sleeve axle center pipe, and high pressure air-flotation type fan
Palace sealing gland bearing, is filled with high pressure air-flotation type labyrinth seal bearing, in the sealing gland labyrinth equipped with labyrinth gas chamber by the clean sky of high pressure
Under the action of body and the air supporting wing, the high pressure air mass bearing that axle sleeve and axle center are contacted with bearing incorporeity is realized, and effectively block powder
Expect excessive, so as to not wear and generate heat, high rigidity crash panel is secondary by composite polycrystal-diamond and high-hardness ceramic plate
High temperature sintering is combined, and is fixed together with thicker axle sleeve, is increased the quality of crash panel system, is realized energetic encounter.This
Invention is nano-milled to dry type to be provided breakthrough crucial skill and states, and is realized the nano-milled axis long time running of dry type, is overcome
The deficiencies in the prior art.
The content of the invention
It is an object of the invention to provide a kind of high pressure air-flotation type nano-milled for dry type to grind shaft, reasonably solves
Not the problem of shaft end seal of the nano-milled axis for the prior art of having determined is not tight and wears fever.
The present invention adopts the following technical scheme that：
