Machine is most important.Thrust bearing is the sole component for carrying axial load, needs accurate axial load spectrum to instruct its design.
The resultant force of supercharger air compressor aerodynamic force and turbine gas power produces booster axial load.The matching of both ends aerodynamic force is uneven
Weighing apparatus, operating condition mutation easily cause the failure of booster shafting, grasp booster axial load and are more conducive to find out compressor
With turbine pneumatic matching grating, optimizes the design of impeller and turbine, facilitate axial force to balance and improve the reliability of complete machine.
Accurate stable state and dynamic axial load are hardly resulted in using theoretical method, this just needs to study accurate and effective survey
Amount method.
Currently, since the compactedness of supercharger structure and the particularity of operating condition limit, turbocharger axial direction power
Measurement mostly uses on thrust bearing patch strain rosette indirect measurement method, this method the problem is that Repeatability difference confidence level not
Height, therefore there is an urgent need to develop a kind of methods of axial force that booster is directly measured using load cell.
Summary of the invention
In view of this, the present invention is directed to propose a kind of turbocharger axial direction power tests structure, to solve turbocharger
The not high problem of axial force measuration poor repeatability confidence level.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of turbocharger axial direction power test structure, including bearing body, thrust bearing, force snesor, compressor carry on the back disk
And chuck, the chuck include suitable disc structure and the hardened structure of the outwardly extending broken line in two sides；The thrust bearing is fixed on card
At the disc structure center of disk, the compressor back disk is fixedly installed on bearing body, and the force snesor is mounted on compressor
It carries on the back on disk, the hardened structure of the broken line of chuck is bolted on force snesor；The chuck and bearing body are in turbocharger
There are the first gaps for axis direction, and there are the second gaps in turbocharger axis direction for chuck and compressor back disk.
Further, the thrust bearing uses independent oil supply mode, is provided with fuel feed hole on chuck, leans on thrust bearing
The side of nearly chuck is equipped with the oil-feed tank of arc, and fuel feed hole is connected to oil-feed tank.
Further, the uniformly distributed multiple fan-shaped supporting tables of the circumferential direction of the side end face for closing on chuck of the bearing body, it is described
Compressor back disk is fixedly installed in the fan-shaped supporting table on bearing body；On the disc structure of the chuck with fan-shaped supporting table pair
Position is answered to be provided with scallop hole, scallop hole is greater than fan-shaped supporting table on bearing body.
Compared with the existing technology, present invention has the advantage that
Booster axial force measurement structure of the invention, by thrust bearing through chuck support in multiple force sensors,
The axial force of turbocharger is measured by force snesor, can directly obtain accurate axial force, is designed, is increased for thrust bearing
The matching of depressor impeller, the mechanical efficiency for improving booster have good directive significance.
