    Sep 01, 2001· Depending on severity, misalignment can destroy a belt in a matter of hours. Sheave misalignment on V-belt drives should not exceed 1/2 deg. or 1/10 -in. of center distance. For synchronous belts it should not exceed 1/4 deg. or 1/16-in. of center distance. Fig. 6. Improper drive maintenance is the biggest source of belt drive problems

    If the belt does not break then the possibility of the belt slipping exists and this depends upon the angle of lap and the coefficient of friction. If the coefficient of friction is the same on both wheels, then slippage will occur first on the smaller wheel. The power at which the belt slips is not the absolute maximum power that can be

  • Understanding Conveyor Belt Calculations | Sparks Belting

    V-belt drives can operate satisfactorily over a wide range of tensions. The ideal tension is the lowest tension at which the belts will not slip excessively at the highest load condition. This will result in the best belt life and lowest shaft loads. However, this ideal tension is hard to determine and difficult to maintain.

    The friction between the belt and wheel may be increased by the shape of the belt. A vee section or round section belt in a vee groove will grip better than a flat belt and is less likely to slip. 4.1 MAXIMUM POWER WITH NO BELT SLIP. The power transmitted by a pulley was shown to beP = ND (F1 - …


    A ratio is a proportional factor between two similar objects of different sizes. In a belt drive system, a ratio is used to determine the speed relation between two v-belt pulleys. The speed ratio would be stable if slippage did not occur; however as belt slip is inevitable, the ratio varies and is therefore only theoretical.
