• ##### Belt slippage basics Vulcan Grip

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. This action is similar in two ways to slightly slipping the clutch in a manual-shift car:

Improper belt tension is the most common and obvious cause of slip, which generates unwanted heat. The friction that occurs when a V-belt slips in a pulley causes belt sidewalls to become glazed

The rotation motion is the ideal and the simplest means of transmission of mechanical power with negligible losses. Rotational motion can be transmitted from one mechanical element to the other with the help of certain systems known as transmission systems or drives.. These systems are driven by a prime mover or transmit the rotational motion to the various parts of a machine within itself.

Fur-thermore the decrease of the friction coefﬁcient with increasing slip speed has to be taken into account as shown by Kobayashi [1998].

• ##### What is the phenomenon of creep in belt drives

when a belt rotates from tighter side to loose side, actually it is going from higher tension to lower tension, so its length becomes shortened on the pulley. so it reduces the angular velocity of driven pulley from that calculated by considering the diameters. it causes a slight relative motion between the pulley and belt.

• ##### Question about belt frequencies Vibration Analysis

The 'straight' side of the unbent belt tries to become convex as the belt is bent, producing a "wedge" effect against the sides of the sheave. You do need tension in the belt to keep the belt down in the groove, but tension is not the 'primary' component of belt grip. As the sheave wears, eventually the belt no longer grips, and starts slipping.
