Bearing block outer surface can so be damaged.Additionally, aperture flow controller and hydrostatic bearing are interference fits in the device, orifice restriction device from
Laid down in hydrostatic bearing, the inner hole surface of hydrostatic bearing and the outer surface of orifice restriction device, static pressure axle after dismantling will necessarily be destroyed
Hold and orifice restriction device is all scrapped.Technology that existing document has been given still is not solved is not damaging hydrostatic bearing, bearing block
Under the conditions of, the maintenance or replacing of orifice restriction device are realized, also can be with the pressure of on-line checking hydrostatic bearing without servicing unit
Failure.
Utility model content
For the technical barrier in background technology, the utility model discloses one kind can on-line checking pressure fault and quick dimension

There is " one " font groove.
The hydrostatic bearing is hollow cylinder, and outer surface is machined with annular groove, inner surface along the circumferential direction uniform 4 faces
The equal annular pressure chamber of product, is threaded hole A and screwed hole B, wherein screwed hole A and aperture section in each annular pressure chamber
Stream device outer surface is coupled by screw thread, and screwed hole B is connected with crossover sub.
The bearing block is hollow cylinder, its inner surface and hydrostatic bearing interference fit, on the surface of bearing block with
Position hydrostatic bearing upper screwed hole A corresponding with screwed hole B has conical screw hole and through hole.Wherein, tapered thread
Hole is aligned with the screwed hole A centers on hydrostatic bearing, and through hole is aligned with the screwed hole B centers on hydrostatic bearing.
Described crossover sub one end is connected through the through hole on bearing block with the screwed hole B on hydrostatic bearing, the other end and
The pressure gauge is connected, for the working condition and pressure fault of on-line checking hydrostatic bearing.
The interior hexagonal plug is cone, and outer surface is machined with tapered thread, is joined with the conical screw hole on bearing block
Capable sealing is tapped into, the stub end end of interior hexagonal plug is provided with inner hexagonal hole.
When the orifice restriction device of hydrostatic bearing is blocked, the pressure reduction in static pressure chamber, pressure gauge registration reduces, passes through
The unexpected reduction of pressure gauge registration is blocked judging orifice restriction device, so that the pressure fault of on-line checking hydrostatic bearing.
It was found that after orifice restriction device is blocked, can first lay down interior hexagonal plug from bearing block with allen wrench, screw is used
Knife is put in " one " font groove of orifice restriction device end face, and orifice restriction device is laid down, and is repaired or is changed, then again according to
It is secondary orifice restriction device to be attached on hydrostatic bearing, interior hexagonal plug is attached on bearing block, realize the rapid-maintenance of hydrostatic bearing
Or change.
Compared with the prior art, what the utility model brought has the beneficial effect that:
(1)The fast of orifice restriction device can be realized under conditions of orifice restriction device, hydrostatic bearing and bearing block is not damaged
Speed maintenance is changed.Solve the problems, such as that hydrostatic bearing orifice restriction device cannot be repaired after blocking;
(2)When hydrostatic bearing works, can be by the change of pressure gauge registration, whether real-time online detection orifice restriction device
Block, the generation of the accidents such as the locking of bearing is prevented early.
