Embodiment Construction

[0017] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0019] The design concept of the present invention is: by improving the local structure of parts such as the bearing body 1, the thrust bearing 2, and the compressor back plate 5 of the general-purpose turbocharger, a chuck 6 is added at the same time, and the thrust bearing 2 is passed through the chuck. The disk 6 is indirectly supported on a plurality of force sensors 4, and at the same time, the lubricating oil required by the thrust bearing 2 is supplied independently, so that the axial force carried by the thrust bearing 2 is transmitted to the force sensor 4 without reservation, and through the force sensor 4 Measure the axial force of the turbocharger.

Abstract

The invention provides a structure for testing the axial force of a turbocharger. The partial structures of components such as the bearing body, the thrust bearing, the compressor back plate, and thelike of a universal turbocharger are improved, and a chuck is added. The thrust bearing adopts separate oil supply. The thrust bearing is supported on a plurality of force sensors through the chuck. The axial force of the turbocharger is measured by the force sensors. The structure for testing axial force of turbocharger can directly measure the axial force of the turbocharger, has high reliability and good repeatability.

Description

technical field [0001] The invention belongs to the technical field of turbochargers, in particular to a turbocharger axial force testing structure. Background technique [0002] As the main part of the turbocharger, the thrust bearing system's stability and reliability are very important to the turbocharger and even the engine. Thrust bearings are the only parts that carry axial loads and require an accurate axial load spectrum to guide their design. The resultant force of turbocharger compressor aerodynamic force and turbine aerodynamic force produces supercharger axial load. Unbalanced aerodynamic matching at both ends and sudden changes in operating conditions are likely to cause failures of the turbocharger shafting. Mastering the axial load of the supercharger is more helpful to find out the aerodynamic matching rules of the compressor and the turbine, and optimize the design of the impeller and the turbine. , helps to balance the axial force and improve the reliabil...
