However, cogged v belts may be a better choice when vibration damping is needed or shock loads cause abrupt torque changes that could shear a synchronous belt’s teeth. Synchronous belts also make a whirring noise that might be objectionable in some applications.

Are notched V-belts better?

Notched belts can use the same pulleys as cross-section standard V-belts. They run cooler, last longer, and are about 2% more efficient than standard V-belts. In contrast, V-belts have a sharp reduction in efficiency at high torque due to increased slippage.

Why should you use a narrow cogged v belt instead of a classical V-belt in a new installation?

Why should you use a narrow cogged v belt instead of a Classical V-belt in a new installation? They can handle more power, they use smaller diameter sheaves, and are more economical than a classical V-belt.

Where would a cogged v belt be used?

Cogged v belts are used widely in mechanical devices, including sewing machines, photocopiers and many others. A major use of cogged v belts is as the timing belt used to drive the camshafts within an automobile or motorcycle engine.
