Thrust Bearing FV2

Thrust Bearing FV2

Functioning sample

The functional sample of the thrust bearing No. 2 (FV2) is conceptually based on the functional sample No. 1 (FV1). The proposed changes make it possible to further reduce the friction losses in the turbocharger rotor system. The bearing contains modified working surfaces of defined shape. Based on the results of technical experiments carried out on the turbocharger with a new design of the bearing, the selected representative parameters were improved. Improvement of the performance characteristics in the form of power losses is achieved over the entire turbocharger operating speed range. The bearing and rotor assembly requires the specified axial bearing clearance designed with respect to the lubricant properties and operating conditions. The thrust bearing functional specimen No. 2 is incorporated into the technical experiment that are part of the turbocharger bearing test program and are verified using series of measurements.
