Chapter 9, Problem 26RQ

Which of the following is considered as the purpose why bearings are lubricated? a. To protect the bearing component from corrosion. b. To carry heat away from the bearing unit c. To help dissipate heat from the bearing unit. d. To provide low-friction film at the point of contact of rolling elements. e. All of the above.

The minimum bearing life is the life that 10% of bearings will achieve or exceed before they fail due to fatigue. Select one: True False

How are porous bearings made and where are they used?

Explain any one type of coupling which can be used to connect two aluminum alloy shafts when there is a lateral misalignment between the axis of the shafts.

The drive shaft component that provides a means ofconnecting two or more shafts together is the __ .a. pinion flangeb. U-jointc. yoked. biscuit

Name the three drive configurations that a greatset can transfer torque.

True or False? Many armature bearings are held in the case by a retainer, whereas bushings are typically pressed out and into their bore.
