Initial tension force Fi is needed to counteract the centrifugal force Fc on the belt and thus keep the belt on the pulley. Fi essentially allows the belt to go around the pulley.
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.
Because of centrifugal force tension on both side will be increased but at the same time normal reaction force in between belt and pulley surface will goes down so frictional tension will be decrease and ultimately power transmission efficiency will decrease.
yes
Technically,Yes. But realistically no. They are both drive belts, but the term drive belt is normally what is referred to as a non-serpentine belt. This term is used to distinguish between the two type belts. A drive belt tension must be adjusted manually, whereas a serpentine belt tension is controlled by a tensioner.
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.
It provides the proper tension on the serpentine drive belt.
Move a pulley
If it is a drive belt and not a serpentine belt is has no tensioner. You manually adjust the tension by normally adjusting tension by moving the alternator. Loosen to bolts holding the alternator in place and then adjust the tension. Tighten the bolts when the tension is right. If it is serpentine belt if you follow the belt around the the engine you will see the tensioner.
centrifugal force independent on tight side & slack side. And depends only velocty of belts only.
I have a 1054 and just put a new drive belt on it. It has a spring loaded belt tension pulley and there is no adjustment. Check and see if the spring has broken or come off the pulley.
Most cars now have a serpentine belt that drive the alternator, water pump, power steering unit, etc. The belt tension pulley is a spring loaded pulley that keeps the proper tension on all these units. It can be moved to release the tension in order to remove the belt.
