Q

-the most common technique of joining sheets of aluminum is riveting.

  • a rivet is any type of fastener that obtains its clamping action by having one of its ends mechanically upset.
  • rivets create a union at least as strong as the material being joined.
  • a well-designed rivet joint will subject the rivets to shear loads.

Q
  1. Do not use a lower-strength rivet alloy as a replacement for a higher-strength alloy unless it is larger than the one that was removed.
  2. Enlarged, deformed, or damaged holes should use the next larger rivet size as a replacement.
  3. The same degree of countersunk must be used
  4. RivetDiameter
    Maximum rivet diameter = 3 times the thickness of the thickest sheet
  5. Rivet Length = 1.5D+ grip length (thickness of 2 plates)
A

RIVETS SELECTION

32
Q

-develop the maximum strength from the sheet metal as determined by the amount of load that the sheet metal must carry.
-is a critical factor so the drilled holes do not weaken the joint.

A

RIVET LAYOUT PATTERN

33
Q

metal sheet will tear out in extreme conditions

A

Edge distance: too close to edge

34
Q

metal sheet separates; contaminants enter the join causing corrosion for instance (Accepeted practice: 2D-4D)

A

Egde Distance:too far to edge

35
Q

the distance between adjacent rivets in a row. (Accepeted practice: 3D-12D)

A

Rivet pitch

36
Q

the distance between rows of rivets in a multi-row layout. (Accepted practice: 75% RP if staggered, RP=TP , If not staggered)

A

Transverse Pitch

37
Q

safer to use; less chances of electric shock and arcing; motor speed is controlled by varying trigger pressure *start slow- hole forms- use faster speed.

A

Pneumatic Drills

38
Q

topn sheet thicker than tapered head. (Tool: standard counter sink, microstop countersink (adjustable))

A

Countersinking

39
Q

a high speed milling tool useful in shaving heads of rivets to obtain accurate flush fit.

A

Microshaver

40
Q

top sheet thinner than tapered head

A

Dimpling (hot/cold)

41
Q

it has Forging action

A

Coin Dimpling

42
Q

it has Folding action

A

Radius Dimpling

43
Q

is a process that mechanically “dents” the sheets being joined to accommodate the rivet head

44
Q

Fast, light blow; small rivets

A

Short Stroke Gun

45
Q

Slow/one shot heavy blow

A

Long stroke Gun

46
Q

radius of depression in the set must be larger than that rivet head, but not so large that edges of the set contract the surface of the metal.

47
Q

when rivet is driven, the actual compression of the rivet is the actual compression of the rivet is not performed by the action of the rivet gun, instead, the rivet is backed up by a metal bar that reciprocates in response to the beats of the rivet gun.

A

Bucking Bar

48
Q

are installed with access to only one end of the rivet

A

blind rivets

49
Q

an early form of the blind rivet. It cannot replace solid shank rivets size for size and must be at least one size larger in diameter.

A

Cherry friction-lock rivet

50
Q

useful for temporarily lining up holes; used in some homebuilt aircraft

A

Pop Rivets

51
Q

designed to prevent the center stem of a rivet from falling out via lock ring as a result of vibration encountered during aircraft operation.

A

Mechanical lock Rivets

52
Q

first mechanical lock rivet; limited to aircraft manufacturers and large repair facilities

53
Q

requires a special pulling tool per size and head shape.

A

Bulbed CherryLOCK

54
Q

lightweight,spindle-type blind rivet; less expensive, only 3 installation tools are required

A

Olympic-Lok

55
Q

economical and replaces solid shank rivets size for size; installed by a one-size puller for all sizes.

56
Q

high-strength and lightweight fastener that can be used in place of conventional AN bolts and nuts. Held in place by a collar, squeezed into position instead of being screwed on like a nut.

A

SPECIAL FASTENERS

57
Q

for both shear and tension applications

A

Lock Bolts

58
Q

withstand bearing and shearing loads

A

Hi-Lok Bolts

59
Q

excellent strength to weight ratio; lighter

A

Hi-Lite Fastener

60
Q

one-piece fastener made of 2 titanium alloys

A

CherryBUCK

61
Q

strongest; creates radial and vertical compression

62
Q

has a bead at the threaded end; preloads the hole to strengthen the joint

A

Hi Tigue Fastener

63
Q

high strength structural fastener

64
Q

threaded rivets; attach rubber deicer boots to aircraft wing and tail surfaces

65
Q

secure inspection plates, doors cowlings and other removable panels on aircraft.

A

Turn-lock fasteners

66
Q
  • unlike rivets and pins, threaded fasteners may be disassembled and reassembled an almost infinite number of times.
  • Aircraft bolts, screws and nuts
A

THREADED FASTENERS

67
Q

loose fit – fingers only – wing nuts

A

CLASS OF FIT: Class 1

68
Q

free fit - screws

A

CLASS OF FIT: Class 2

69
Q

medium fit – aircraft bolts

A

CLASS OF FIT: Class 3

70
Q

close fit – requires wrench

A

CLASS OF FIT: Class 4

71
Q

tight fit – requires wrench

A

CLASS OF FIT: Class 5

72
Q

The hole is larger than the shaft, enabling the two parts to slide and/or rotate when assembled.

A

Clearance Fit

73
Q
  • The hole is fractionally smaller than the shaft and mild force is required to assemble/disassemble
A

Transition Fit

74
Q

The hole is smaller than the shaft and high force and/or heat is required to assemble/disassemble
