CHAINS VERSUS BELTS
Name: Trần Hồng Thái
Class : 11CDT1
Hello Everyone
Material
Drive chains
•
Metal
Belts
•
Rubber, plastic, or other
substances
Well-made chains may prove
stronger than belts
Their greater mass increases
drive train inertia.
Advantages and Disadvantage
Chain
•
Not slip
•
May rotate at a prcise
speed
•
Conventional roller chain
drives suffer the potential
for vibration
•
Chains are often narrower
than belts

Belt
•
Can often slip (unless they
have teeth)
•
May not rotate at a precise
speed
•
Teeth on toothed drive
belts generally wear faster
than links on chains
Chain
•
The more positive meshing
of a chain can make it easier
to build gears that can
increase or shrink in
diameter, again altering the
gear ratio.
•
Often used to move things
vertically by holding them in
frames
Belt
•
Good at moving things
horizontally in the form of
conveyor belts
•
Wear on rubber or plastic

belts and their teeth is
often easier to observe.
Example
•
Chains are often narrower than belts, and this can
make it easier to shift them to largeror smaller gears
in order to vary the gear ratio. Multi-speed bicycles
with derailleurs makeuse of this
Chains are often used to move
things vertically by holding
them in frames
Belts are good at moving
things horizontally in the
