A Comprehensive Guide To Timing Belt Sizing and Selection

Article by ,

It is imperative that you settle down on the right timing pulley to enhance the functionality of your power transmission systems. However, this could be an arduous and daunting task without having any prior knowledge in this arena. You would need to have a rudimentary understanding of the tenets of belt sizing and selection for the multiple drive system categories. This would be necessary for you to convert your customizations to the system design engineer who would be responsible for the construction of the drive systems.

Roller Chain Drive Systems

This category of drive system happens to be very easily found and economical. Moreover, they are also versatile enough to be used with many lugs and pulley design variations. They are sustainable and have a prolonged lifespan, making them ideal to be operated in the most robust of conditions. Chain drive systems, on the other hand, are comparatively louder and more susceptible to wear and tear in relation to their polyurethane or elastomer belt system counterparts. This is why they necessitate regular maintenance and the chain and sprocket drives require frequent lubrication.

 

Friction Belt Systems and Synchronous Belt Systems
These two belt profiles are widely used in the industry and are propelled by the friction generated by high design belt tension to set the pulley in motion. The V-belt drive is a little better in comparison in terms of efficiency, load capacity, friction resistance, and sound. In contrast, flat belt drives are more inexpensive owing to their simplicity of structure.

A friction drive system relies on the design of the pulley that is competent to stabilize belt tensions that are prerequisite to the transmission of power without any slips. Excessive loading might very well lead to an overhung load on the shafts of the pulley. This can be evaded with customized designs by a reputable engineer. Apart from that, heating and cooling equipment should also be incubated into the structure if needed. Nevertheless, in terms of the power loads, synchronous belt systems are far more proficient.

 

Sizing

After knowing about the varying kinds of belt drive systems, the system design engineer would have to identify and deduce the size of the required drive system depending on the magnitude of the load that would need to be transmitted. In this context, the most important determinant that would have to be determined would be the system design power. Following that, the required belt width for the drive system would also need to be calculated as a direct function to the design power of the application.

 

Evidently, there are several other determinants that would have to be taken into the equation; however, the principal determinants remain to be system design power and the width of the belt. These pointers would be the point of commencement for a system design engineer to construct the preliminary model. It must be incorporated that each system is built for its own unique purpose and thereby would necessitate differing circumstantial customizations.

 

If you need to consult an expert regarding timing belts or need a reliable manufacturer of the product, you could consider soliciting the services of Rainbow Precision Products, a pioneering name in this industry since 1992.
