synchronous drives represent a modern and efficient power transmission. They essentially combine the advantages of mechanical components (gears and chain) and flexible components (V-belts and flat) while eliminating the disadvantages inherent in these components.
The main components of a synchronous drive are the tensile cords, teeth, rubber mounting face and teeth. The steel was used as a tensile cord material. Most belts today use a high modulus (low elasticity) fiberglass or aramid fiber as a traction element. the pull cord is the supporting component of load of the synchronous belt. The teeth of the belt are molded of a compound of hard rubber enveloped by a tough, abrasion-resistant nylon face of the teeth. The resistance to compression and shear of the teeth is greater than that of the tensile cords when there are at least six teeth meshed with the drive pulley. A durable rubber coated cord tensile load support. It protects cords of dirt, oil and other contaminants, as well as frictional wear when an idler backside is used
Synchronous belts operate on a basic principle of :. molded belt teeth and mating grooves of the pulley make a positive commitment. The teeth in and out of the pulley in a way runnability with low friction. This positive engagement results in synchronizing the exact tree, eliminating slippage and loss of common speed V-belts. Synchronism with speeds over most of the chain drives.
When using a synchronous belt drive? There are a lot of situations. For example, the drive efficiency and high mechanical energy savings are needed. Compact drive layout is necessary. Low maintenance is required or low noise is required.
All timing belts operate on the principle of positive engagement. Chains operate on the same principle but timing belts have many superior characteristics. The latter envelope around the pulley by means of bending, not by the rotation of the articulated elements, which eliminates one of the causes of wear and noise. With them, the catch allocations required to tender are much less. Synchronous belts no hidden costs. They have larger availability ratios and lengths.
