  • The speed ratio between the driving and driven sheaves

  • 2. 
    What is a photo-reflective tachometer used for?

  • Measures the torque on a sheave.
  • Measures the speed of a sheave.
  • Takes a picture of a sheave as it rotates.
  • Measures the wear on a belt.
  • Examines the surface of a sheave.

  • 3. 
    Which tool is used to check for sheave parallel alignment?

  • Straightedge
  • Combination square
  • Tape rule
  • Feeler gauge
  • No tool is needed, the eye is precise enough

    Which parameters are represented by the two scales on a belt tension tester?

  • Deflection distance and belt span
  • Deflection force and belt type
  • Deflection force and belt width
  • Deflection distance and small sheave diameter
  • Deflection force and belt span

  • 5. 
    Which type of belt is used with sprockets?

  • F.H.P V-belt
  • Timing belt
  • Flat belts used on conveyors
  • Multiple V-belts
  • None

  • 6. 
    What is the drive misalignment called that results when the sheaves are at a different angle with the vertical plane?

  • Parallel misalignment
  • Horizontal angular misalignment
  • Vertical angular misalignment
  • Planar misalignment
  • Vertical parallel misalignment

  • 7. 
    Which of these belts are well suited for timing mechanisms?

  • Flat belt
  • V-belt
  • Synchronous belt
  • Multiple V-Belt
  • All types can be used

  • 8. 
    Power is transferred between an electric motor and a pump with a belt drive. Calculate the required driven sheave pitch diameter and belt length if the motor and pump shafts are 20 inches apart and the pump shaft must rotate at 1800 r/minute. The driving sheave is installed directly on the motor shaft and has a pitch diameter of 5 inches. The plate on the motor indicates a nominal speed of 1000 r/minute.

  • Driven sheave pitch diameter is 2.8 inches and belt length is 52.2 inches.
  • Driven sheave pitch diameter is 9 inches and belt length is 52.2 inches.
  • Driven sheave pitch diameter is 9 inches and belt length is 62 inches.
  • Driven sheave pitch diameter is 2.8 inches and belt length is 62 inches.
  • Impossible to tell from the given data

  • 9. 
    If the driving sheave of a belt has an outside diameter of 6 inches and the driven sheave has an outside diameter of 3 inches, the driven sheave rotates

  • two times faster than the driving sheave
  • half as fast as the driving sheave
  • slower than the driving sheave
  • at the same speed as the driving sheave
  • impossible to tell from the given data

  • 10. 
    What should be used to clean belts?

  • A solvent
  • Soap and water
  • A glycerine/spirit mixture
  • Sandpaper
  • They should never be cleaned
