Description
Technical field
The present invention relates to the air supporting field.
Background of invention
Along with the development of science and technology, often adopt gas lubrication to replace common mechanical lubrication, pressurized gas are introduced in the object gap of relative movement and formed air film, avoiding directly, contact realizes frictionless motion.
The mode that air-floating apparatus forms air film is different, air supply method is also different, usually all be to utilize tracheae to introduce gas in hyperbaric chamber, but no matter adopt which kind of plenum system, tracheae all must not produce disturbing influence to air-floating apparatus, for some air-floating apparatus with respect to the source of the gas motion, there is a very large difficult problem in the air supporting air feed.Such as the folding hinge plate of side by the vertical placement of hinge links, the bottom realizes that by a plurality of floating cushions planar frictionless launches motion, do not introduce any external force when requiring to launch, if each floating cushion is introduced tracheae from the outside, floating cushion moves with hinge, and steam line can produce on the motion of floating cushion the impact of disturbance, and the air feed circuit is many, easily twist, crooked, twine, be not easy to installation and maintenance; Usually with air supply pipe attached onboard from one be incorporated into another piece simultaneously air feed to the floating cushion on this plate, but hinge plate can be subject to the disturbing influences such as bending of joint tracheae, winding, the expansion of interference hinge from fit-state when launching.
Summary of the invention
The deficiency of the impact of the crooked disturbance of tracheae when having the air-floating apparatus air feed now in order to solve, the taper that the invention provides a kind of continuously unaffected by disturbance of air pipes of air feed supplies air flotation device without the friction rotation.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of taper supplies air flotation device without the friction rotation, comprise air-bearing shafts, air supporting cover and base, the air supporting cover is comprised of air supporting stock and tapered ring restrictor bearing housing, described air suspension shaft sleeve is contained in the air supporting cover, there is micro-gap between described air-bearing shafts and the air supporting cover, described air-bearing shafts and air supporting cover fitting surface are tapered, described base and air supporting cover bottom surface are fixed, the uniform throttle orifice in described tapered ring restrictor bearing housing surface, described throttle orifice is vertical with the conical surface of tapered ring restrictor bearing housing, one circle throttling groove is arranged on the inner peripheral surface of described throttle orifice place, described tapered ring restrictor bearing housing be fixed on the air supporting stock inwall and and the air supporting stock between form the air inlet hyperbaric chamber, the air supporting inlet hole is arranged on the described air supporting stock and communicate with the air inlet hyperbaric chamber, the air feed suction port is arranged at described air supporting stock bottom, described air-bearing shafts bottom and air supporting stock, base forms hyperbaric chamber, described air feed suction port communicates with hyperbaric chamber, described air-bearing shafts center is beaten blind hole and is communicated with the air outlet, top, unload pore on the described air supporting stock, it is described that to unload pore uniform and communicate with gap that air-bearing shafts and air supporting cover forms at air supporting stock circumferencial direction, described unloading has the circle spill to unload air drain on the circumference of pore place, the described pore that unloads does not communicate (namely mutually isolating) with throttle orifice and air supporting cover inlet hole.
Further, described air supporting inlet hole and air feed suction port adopt same gas source feed by tracheae, and draw pressurized gas by tracheae air outlet, described top.
Mentality of designing of the present invention is: according to the air-bearing principle, realize nothing friction rotation between air-bearing and the air supporting cover, again by special plenum system, pressurized gas are drawn from air-bearing shafts from the introducing of air supporting cover, thereby realize without friction rotation air feed.
Air supporting inlet hole and air feed suction port adopt same high-pressure air source air feed on the air supporting frame, pressurized gas in the air inlet hyperbaric chamber form air film through throttle orifice in air supporting cover and air-bearing shafts gap, gas major part in the hyperbaric chamber of bottom flows out from the air outlet through the air-bearing shafts center hole, fraction enters in the gap of air supporting cover and air-bearing shafts, unload the pore hole on the air supporting frame, enter the pressurized gas in gap through discharging from unloading pore behind the damping seal, air-bearing shafts communicates with atmosphere with an end in air supporting cover gap, the other end unloads pore, therefore there is pressure gradient in the gap, one effluent goes out from the gap to enter a gas part in the gap, and another part is discharged by unloading air drain.Adopting the taper air-floating apparatus is because the taper air-floating apparatus can resist certain axial force, prevents that bottom hyperbaric chamber inner high voltage gas from acting on the air-bearing shafts and increase additional force or cause the air-bearing shafts play.
Be expanded to by fit-state under the folding effect of hinge plate at hinge in 180 ° the process, on the axis of rotation when being installed in two pages of folding hinge plates expansion without friction rotation air feeder, base, air supporting cover are fixed with a plate, air-bearing shafts is connected with another piece plate, therefore pressurized gas just are delivered on another piece plate from a plate, be not subjected to the disturbance of tracheae rotating bending, rotate the outer diameter of air feed less than or equal to the thickness of hinge plate without friction, avoid fit-state a plurality of without phase mutual interference between friction rotation air feeder.
Beneficial effect of the present invention is: continuous air feed, unaffected by disturbance of air pipes.
