Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, a kind of foil bearing lubrication rotates cavity jet rotor, comprises simulation pump impeller 1, radial foil bearing cooling and lubricating hole 2, mixing foil bearing cooling and lubricating hole 3, thrust disc 4, thrust foil bearing cooling and lubricating hole 5, rotor shaft 6.Simulation pump impeller 1 is connected with rotor shaft 6 by screw thread, thrust disc 4 is connected with rotor shaft 6 interference fit, radial foil bearing cooling and lubricating hole 2 is positioned at rotor shaft 6 surface, and mixing foil bearing cooling and lubricating hole 3 is same with thrust foil bearing cooling and lubricating hole 5 is positioned at rotor shaft 6 surface.
Simulation pump impeller 1 there is simulation pump impeller oil inlet hole 8, be the passage that fluid flows into, make fluid can enter rotor shaft 6 inner.
As shown in Figure 2,3, thrust disc 4 and rotor shaft 6 interference fit, thrust disc 4 is inner is oil guiding hole 9 in hollow-core construction formation thrust disc, thrust disc 4 has thrust disc oil outlet 7 to be axially uniformly distributed along thrust disc 4 above, porosely on rotor shaft 6 be communicated with oil guiding hole 9 in the thrust disc of thrust disc 4 inside, in thrust disc, oil guiding hole 9 is communicated with thrust disc oil outlet 7.
As shown in Figure 4, rotor shaft 6 boring, there are mounting point and the tachometric survey plane 10 of thrust disc 4 in centre, rotor shaft 6 is distributed with mixing foil bearing cooling and lubricating hole 3 and radial foil bearing cooling and lubricating hole 2; Radial foil bearing cooling and lubricating hole 2 is distributed in the position near simulation pump impeller 1, and the paillon foil that the fluid of High Rotation Speed can be made radially to enter bearing surface carries out cooling and lubricating to it; Mixing foil bearing cooling and lubricating hole 3 is distributed near thrust disc 4, and making high-velocity fluid make flow direction transfer axis to by radial direction by thrust disc transfer conveniently can carry out moderate lubrication and cooling to thrust paillon foil; Tachometric survey plane 10 is positioned at rotor shaft 6 surface, in order to the measurement of rotating speed.
During work, the mode that simulation pump impeller 1 is threaded connection is fixed on High Rotation Speed rotor shaft 6 in order, and during work, ultra high speed rotor shaft 6 is being overlapped High Rotation Speed under the region oil film support of getting up by paillon foil.Radial foil bearing cooling and lubricating hole 2, mixing foil bearing cooling and lubricating hole 3 and thrust foil bearing cooling and lubricating hole 5 are evenly distributed on rotor shaft on the surface by laser beam machining, the thrust disc 4 that during work, thrust paillon foil and ultra high speed axle are fastened contacts, to ensure matching gap axial in installation process.When rotor shaft High Rotation Speed, low pressure oil flows in cavity rotor by the oil inlet hole 8 in simulation pump impeller, centrifugal force is made pressure oil be arrived respectively by each jetburner successively and specifies lubrication paillon foil place, and part oil arrives thrust paillon foil working zone by the oil guiding hole 9 on thrust disc.When axle high speed rotational operation, monitor axle system running speed by tachometric survey plane 10, to control initial pressure and the flow distribution of low pressure oil.
