Question 695Steam Plants - Assistant Engineer
70% to passChamfers, located at the parting edges of horizontal split sleeve type bearings, are used to facilitate oil storage and distribution. They are machined _______________.
Aradially the full length of the bearing
Bradially, to within 45 degrees of the normal bearing surface
Caxially the full length of the bearing
Daxially, approaching but not extending to the end of the bearing
AI Explanation
The correct answer is D) axially, approaching but not extending to the end of the bearing. Chamfers on horizontal split sleeve type bearings are machined axially, approaching but not extending to the end of the bearing. This design facilitates oil storage and distribution by creating a recessed area at the parting edges of the bearing. The chamfers do not extend the full length of the bearing, as that would compromise the structural integrity of the bearing surface. The other options are incorrect because they do not accurately describe the proper orientation and extent of the chamfer machining on this type of bearing.
