The influence of radial clearance of sliding bearing on superheat failure of bearing Liang Baoying;

The radial clearance of tLhe big joumal bearing in rock bit's bearing system is of great importance to the service behavior of the bit.

Taking the manufacture clearance into consideration under the special torque load and a constant speed,the right radial clearance of roller bearing is solved out through selecting among roller bearings with different radial clearances and making a summary of the analyzing results.

The analysis on the radial gap of the axial flow fan;

Theoretical analysis of fluid flow within radial gap in balancing disk of multi-stage-section pump;

The work is detailed and complex to replace the rotary blades and the stationary blades,and the key question is how to determine the shape size of blades to ensure the radial gap.

The function of UG software as an example of air passage design for the car air-conditioning was mainly introduced,including the function of dummy assemble,the one of intervene/clearance check,the analysis of CAE hydrodynamics,the analysis of man-machine engineering,and the function of dummy praxis etc,giving prominence to the advantage of UG software in air passage design for the car air-co.
