Question 83Steam Plants - QMED
70% to passWhat type of thrust is the bearing shown in the illustrated steam turbine shaft bearing designed to absorb? Illustration SE-0007
ACombination of radial and axial thrust
BRadial thrust only
CAxial thrust only
DPerpendicular thrust only
AI Explanation
The correct answer is C) Axial thrust only. The steam turbine shaft bearing illustrated in SE-0007 is designed to absorb axial thrust, which is the force acting along the longitudinal axis of the shaft. This type of bearing is commonly used in steam turbine applications to support the axial movement of the rotating shaft as it is driven by the steam. The other options are incorrect because this bearing is not designed to handle radial thrust (force perpendicular to the shaft) or a combination of radial and axial thrust. Its primary function is to counteract the axial forces generated by the steam turbine's operation.
