A boxed key is a square or d. rounded
rectangular key that has both its Buried, Whitney and Pratt are all types of
ends ___________ boxed
a. boxed key
b. Chisled
c. filed
d. rounded
When using a hydraulic puller 7-10 times
cesect
a puller that can withstand
_______
force of the diameter of the shaft in
inches
When using a jaw puller the half
diameter
of the adjusting screw should be
atleast __________ of the shaft
,Internal resistance offered by a stress
unit Normal stresses are either tensile or
area of a material to an externally compressive
applied load tensile-lengthen
compressive-shorten
bending stresses are a combination of
tensile and
compressive
Shoulders and shaft modifications ratio between 2 diameters
the amount of stress concentration size of fillet in the coner where the
depends on two factors diameter
changes
This is a cold finished steel in the d. C1018
low Diameters are mounted to a minus
carbon range that welds readily. tolerance
a. C1045 (undersized) allows for imperial bearings
b. C1050 installed
c. C107 directly to shaft
d. C1018
, The two parallel keyseats most d. less in runout than profile because of its
frequently used are profile and run smooth
out. the stress concentration factor longitudnial radius at ends
is?
a. less for profile than run out
because of its smooth longitudnial
radius at ends
b. equal between the two
c. more in tolerance than
clearance
d. less in runout than profile
because
of its smooth longitudnial radius at
ends
When sections of the shaft need to 1.5-1
be turned down the reduction in fillet radius should be a large as possible
diameter should be no more than?
Where are hollow shafts used? centrifugal pumps used to pump slurries or
corrosive fluids
Sunk keys are similair to square a. both ends
keys. *Sunk keys are set deeper into the shaft
They are adapted for applications than plain
where the mating machine keys are
components restrict accessibility at
_____________ of the key
a. both ends
b. top end
c. center
