Description
Technical field
The invention belongs to field of turbochargers, specifically a kind of integral movable balance clamp of turbocharger.
Background technology
The working speed of wheel supercharger generally exceedes first critical speed, even second order critical rotary speed all, belongs to around property rotor.If balance not in place, during work, turboshaft can produce violent being out of shape and internal stress around property, makes supercharger produce vibration & noise, accelerates the wearing and tearing of bearing and sealing ring part, impeller and housing can be caused to collide, cause supercharger directly to damage time serious.Along with improving constantly of contemporary turbocharger rotating speed and performance, only according to traditional low speed single-piece transient equilibrium (pneumatic plant, turbine and rotor), can not meet requirement far away.Whole dynamic balance test must be carried out to its movement assembly, and nonconforming person is corrected, the reliable running at work of guarantee supercharger.The whole dynamic balance of turbosupercharger makes Rotor-Bearing System carry out break-in campaign, improves and ensure that dynamic balance accuracy, can replace the delivery test of carrying out on hot blast testing table.
The dynamically balanced type of drive of body is all generally adopt technique volute as the fixture driving turbine rotation and turbosupercharger to fix.The shortcoming of this mode is: the mould of technique spiral case and processing cost are all higher, and the supercharger of different model just needs to process different technique spiral cases, does not have interchangeability, is not suitable for the mode of production of multi-varieties and small-batch; The general runner of technique spiral case needs to design all more roomy in addition, and in order to drive supercharger to turn to rated speed, the traffic demand for source of the gas also can be very very large.
Summary of the invention
The present invention is directed to the weak point existed in above-mentioned technology, propose a kind of integral movable balance clamp of turbocharger.
Present invention employs following technical scheme:
Integral movable balance clamp of turbocharger, it comprises the movement for test specimen, movement one end is fixed with gas compressor blade wheel cover, the other end is provided with fixation clip and mounting disc, movement is pressed in mounting disc by fixation clip, mounting disc upper end is fixed with airflow path cavity part, mounting disc lower end is fixed on the base of air-source inflow chamber, airflow path cavity part fixes the airflow path die cavity forming turbocharger vanes by back shroud capping, the end side face that described movement is positioned at airflow path die cavity is fixed with nozzle cage, this nozzle cage is provided with some inclined holes, the outlet of inclined hole is positioned on the side face of nozzle cage.
Installation sleeve is provided with inside described back shroud.
Described air-source inflow chamber base is fixed in mounting seat.
Advantage of the present invention is realized by a foraminate nozzle cage of band, the inclined hole that the blade-shaped of this aperture and inner chamber and turbine is angled, source of the gas demand can be reduced, and provide larger driving force not need special die sinking as much as possible, greatly reduce production and use cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of gas compressor blade wheel cover;
Fig. 3 is the structural representation of mounting disc;
Fig. 4 is the structural representation of nozzle cage.
Embodiment
As Fig. 1, shown in Fig. 2, integral movable balance clamp of turbocharger, it comprises the movement 3 for test specimen, movement 3 one end is fixed with gas compressor blade wheel cover 2, other end side face is provided with fixation clip 4 mounting disc 5, movement 3 is pressed in mounting disc 5 by fixation clip 4, mounting disc 5 upper end is fixed with airflow path cavity part 7, mounting disc 5 lower end is fixed on air-source inflow chamber base 10, airflow path cavity part 7 is by the fixing airflow path die cavity 7a forming turbocharger vanes of back shroud envelope 9 lid, the end side face that described movement 3 is positioned at airflow path die cavity 7a is fixed with nozzle cage 6, this nozzle cage 6 is provided with some inclined hole 6a, the outlet of inclined hole is positioned on the side face of nozzle cage, installation sleeve 8 is provided with inside back shroud 9, air-source inflow chamber base 10 is fixed in mounting seat 11.
Another technology improving supercharger integrated dynamic balancing machine rotating speed adopts gas compressor blade wheel cover, as shown in Figure 2, it is designed to a simple cylindrical shape cover, and one end is closed, the other end when testing with intermediate end contact, do not have air to enter in pneumatic plant to compress when testing like this.If adopt actual compressor casing, compressor impeller rotates needs consumed power, and this just increases the specific air consumption of turbine end.Adopt actual compressor casing in addition, increase with the area of intermediate, add the difficulty of sealing, if seal bad, also have more gas leakage.
Mounting disc, as shown in Figure 3, in figure, a is for being arranged on mounting hole on airflow path die cavity 6, and b is fixation clip mounting hole.The structure of the structure Main Basis movement intermediate whirlpool end of mounting disc and designing, makes it have good sealing property.
As shown in Figure 4, the part matched at turbo blade has the inclined hole of a circle circle to nozzle cage, and high pressure draught impacts on turbo blade by these inclined holes, drives turbine High Rotation Speed, the Vibration Condition under analog operation state.Size and the molded line of the design Main Basis turbine of nozzle cage design.For the ease of processing and reducing costs and can adopt aluminum component.
