Abstract

The invention discloses a supercharger device for measuring the axial force of a turbocharger. The device comprises a gas compressor part, a turbine part and a connecting structure part, an impeller shaft arranged in a bearing body at the air compressor end is connected with a turbine shaft arranged in a bearing body at the turbine end through a flexible coupler, a connecting flange of the bearingbody at the air compressor end and a connecting flange of the bearing body at the turbine end are hermetically connected together through a connecting sleeve and are fixedly connected through a screwrod, a gas compressor assembly and a turbine assembly both comprise thrust structures, strain gauges are arranged at the thrust structures, and the strain gauges are connected with secondary instrument signals during test. According to the device, the shaft structure of the turbocharger is changed, the coupler and a fastening device are additionally arranged, the turbocharger is divided into twoindependent units, the flexible connection is realized, the rotation speed is synchronous, the torque can be transmitted without affecting the axial force, and the independent test of the axial forceof the gas compressor end and the independent test of the axial force of the turbine end are realized.

Description

technical field [0001] The invention belongs to the field of electromechanical technology, and in particular relates to a supercharger device, a shaft coupling and a measurement method for measuring the axial force of a turbocharger. Background technique [0002] The axial force of the turbocharger is the resultant force of the axial force of the compressor and the turbine. Both the compressor and the turbine of the turbocharger generate axial force on the thrust bearing. The direction of the axial force of the compressor and the turbine under different working conditions and values ​​change. Understanding and evaluating the direction and numerical changes of the axial force of the compressor and turbine under different working conditions is very important for improving the structural design of the compressor and turbine. [0003] However, in the prior art, only the resultant axial force of the entire turbocharger can be measured, and the variation of the axial force at the...
