There are a number of factors that would affect the answer to this question including torque, shaft speeds, load etc. This is why there are many methods of delivering force to remote locations (worm, belt, chain). I believe some of the advantages when working with belts are - reduced friction losses as the belt has more contact area - decreased energy loss through vibration (in effect a belt has vibration dampening) - belt breakage usually seperates the drive system causing little damge or danger unlike chain If someone can answer the physics side of this I would be most appreciative as most of these answers come from car knowlege (see variable belt drive vs. timing chain).
types of belt drive.
As with any other rotational system in a belt drive during rotation, the belt is subjected to centrifugal force. Due to the centrifugal force the belt is thrown outward from the grooves of the pulley and causes additional tensioning of the belt. The effect of centrifugal tension is that it reduces the pretension of the belt and hence increases belt slip.
You're probably getting a little water on the belt. Check to see if there is a dust cover, mud guard or whatever it's called for your vehicle. Someone may have removed it over the years and now when you splash water it causes the belt to slip.
Engine idle is too low, alternator drive belt is slipping, alternater is defective, voltage regulator is defective.
V Belt and Serpentine Belt.
Sleep and creep does not take place for the v-belt. compare to flat belt it will be very less.
Adjusted too loose, belt is glazed over and worn out, replace it.
The accessory drive belt and the timing belt.
Replacement for a "V" belt to drive engine accessories i.e. p.s., alternator, a/c compressor etc. A toothed belt offers a better grip and "wrap" than standard "V" belt
A belt drive is an alternative to a chain drive (as you would normally find on a bicycle or motorcycle). There are several types of belt used in belt drive systems including V-belts and toothed belts. The more common is the V-belt. A cross section of the pulley used shows that the belt runs in a V-shaped groove. Washing machines, older cars, and machinery use this type of belt system. The toothed belt is normally wide and flat with teeth on the inside to prevent slippage. Harley Davidson motorcycles use these, as do super-charged engines in cars.

No, the serpentine belt is used to drive more than one thing and tension is automatically adjust by way of a spring loaded idler pulley. Normally it will drive the alternator, power steering pump, & A/C compressor. A drive belt normally drives only one thing and tension is manually adjusted. A serpentine belt is wider that a drive belt and is not a V-Belt like a drive belt.

What do you mean by drive belt. If your talking about the serpentine belt, it should have an auto tensioner. Same goes for the timing belt. There is no adjustment. If the belt is loose then it needs to be replaced. ed724

V Belt is thin and V in shape, and is normally used to power a single component in a system of pulleys. Serpentine Belt is wider, and is used to drive multiple components in automotive engine, it loops continuous over several pulleys. In addition, V Belts are normally found in older automotives.
