In what way are grid couplings different than chain coupling? - Grid couplings allow for more
misalignment because they are torsionally more flexible
Knowing that sprockets are used for chain drives and sheaves used are for V-belt drives, what do you
attach to a bushing to complete a timing belt drive? - A pulley
Before removing a machine guard to fix a machine, what step should a maintenance technician perform?
- Lockout/Tagout the machine
A bushing is a component that __________. - attaches a sheave to its shaft
A chain drive sprocket must be replaced. The chain is a roller chain with a pitch of 3/4 of an inch. The
sprocket must have 35 teeth, double strand, and type C hub with a finished bore. What is the sprocket
code? - D60C35
A common method of mounting type A sprockets to a shaft is - Weld them to the shaft
A probable cause for chain wear and breakage in a chain type coupling is __________. - coupling
misalignment
A probable cause for excessive stretch in a belt drive system can be __________. - excessive
tension
A v belt match code is used to: - Identify belts to be used in a multi belt system
A V-belt match code of B40 52 would mean the belt is __________. - 40.2 inches in length
After aligning the sprockets, what is the next step for installing a chain drive? - Mount the chain
, Chain pitch is important because it specifies both chain size and __________. - length
Chain pitch specifies - Chain size and length
For low to moderate speeds what is the proper way of tensioning a timing belt? - hand tensioning
or "use feel"
Grease as a lubricant is best suited for applications where? - A oil would not stay in place
How do you calculate the ratio of pulleys in a timing belt system? - Number of teeth of the driven
over the number of teeth of the driver
How do you calculate the ratio of sheaves in a V-belt drive system? - Diameter of the driven over
the diameter of the driver
In the wedge belt code, the nominal belt length is interpreted as - 1/10 of the outside length of
the belt
One of the advantages of elastomer couplings over flexible metal couplings is that they __________. -
dampen vibration better
The cause of a v belt slipping or squeaking during operation is _______________. - Insufficient
tension
The most likely reason for chain wear and breakage in a chain coupling is - Coupling misalignment
or insufficient lubrication
The purpose of the kiss idler in a belt drive is to __________. - reduce vibration or belt whipping
The wedge V-belt __________. - will carry the same load with 40% smaller cross section than a
conventional V-belt
