Belt slippage occurs whenever torque demand exceeds the available friction between a V-belt and one or more of the pulleys (sheaves). When this occurs, the belt begins to slide backwards a bit as it moves with the pulley.
Treadmill Belt Is Too Loose or Too Tight

If the treadmill rolling belt isn`t properly tensioned, it can come off the roller and slip. An ill-fitting belt can wear out quickly, which leads to more slipping and the need for frequent adjustments.

The “Deck Belt” goes around the pulleys right above the blades on the deck and then to a double pulley. The “Drive Belt” on your mower goes from the transmission, around an Idler pulley then over to the double pulley I mentioned before. The Drive belt also plays a role in making the wheels turn.
A perfectly tight mower belt can rotate without slipping off but not cause the engine to over-exert and overheat. If the belt does not slip off while working and is not producing unfavorable sounds that indicate wearing off of the belt, then that is the perfect tightness for it.
Burned or Glazed Side Wall: As the mower belt continues to get used, the belt will wear down. As a mower belt wears down, the side wall of the belt will begin to look burned or glazed. This is another sign that your belt is worn and needs to be replaced.
Lawnmower Pulley. Photo by djuggler on Flickr. The ability to transfer the torque, or power, from the engine to the transmission comes from the way the drive belt runs on the lawnmower. The drive belt is installed on pulleys which are attached to both shafts: the engine shaft and the input shaft of the transmission.
If the belt is worn (dry, cracked,glazed) it can slip on acceleration and make a squealing sound. Also, if any of the pulleys on the alternator, p/s pump,etc, are worn or loose, they can cause the belt to squeal.
