imt-161 final review

When using the combination rim and face alignment method, angular misalignment in the horizontal plane is by measuring the face of the coupling at

• 12 and 6

• 3 and 9

When using the combination rim and face alignment method, angular misalignment in the vertical plane is checked by measuring the face of the coupling at

• 12 and 6

• 3 and 9

why does angular soft foot exist

• when two of the machine feet are bent and not on the same plane as the other feet.

• when three of the machine feet ae bent and not on the same plane as the other foot

• when one machine foot is bent and not on the same plane as the other feet.

what is the dowel effect

• basically the machine has a very big hole in it

• a condition when the bolt hole of a machine is so large that the bold head forces the washer into the hole opening on an angle

what causes a dent race in an antifriction bearing

• excessive vibration

• excessive heat

• excessive spinning

• water damage

why do roller bearings have a higher load capacities than ball bearings

• roller bearings have less surface area

• roller bearings have more surface area

With oil bath lubrication of ball bearings in a gearbox, the oil level should never be_________ than the center of the lowest ball in the bearing housing.

• higher

• lower

what is a grease drop point

• the point at which grease will drop

• the point at which the grease will liquefy

• the point at which grease will solidify

what is a natural lubricants

• graphite

• copper

• silicon

An organic solid lubricant, such as graphite, is suitable as an oil additive when used in machinery bearings subjected to high temperatures.

• low temperatures

• heavy loads

• high temperatures

• light loads
