4. footstep bearing is an axial load bearing. (a) true (b) thrust load (c) shear load (d) none of the listed
Answers
Answer:
Footstep bearing isn't an axial load bearing. It is a Thrust Load. Therefore, the correct answer would be (b) Thrust Load.
Explanation:
An axial thrust load is generated at the compressor rotor via way of means of gas forces in the machine. The usual thrust force may be decided from the sum of forces performing at every impeller, at every shaft end, and at every seal. The usual axial thrust load will range over the compressor running envelope.
On immediately via compressors, a stability piston is positioned adjoining to the closing degree impeller to in part stability the thrust from the impellers and seals in the compressor. The pressure appearing at the stability piston is contrary of the impellers and is because of the differential stress throughout the piston among the high-stress hollow space on the closing degree impeller and the lower-stress hollow space outboard of the stability piston, that's linked to the compressor suction.
