All standard sized timing belts use the same specific design. This includes either an English or a metric pitch which is standardized and used universally by timing belt manufacturers and OEMs around the globe. There is also the option to use a custom designed timing belt. This is a slightly more costly option, but it also works well for unique and original equipment designs where current English or metric pitch belts simply will not work.
In addition to the choice between a standard or a custom pitch for timing belts, OEMs will also need to consider the options in materials. Top manufacturers of these belts can be instrumental in determining if silicone, polyurethane or specialty materials are the best options given the specific application, the working conditions as well as the desired life cycle for the belt.
Choice of Kevlar for Reinforcement
One option to consider is the choice of Kevlar as a material component of the timing belt. Kevlar timing belts can be used in power transmissions, specialized equipment and is often considered the reinforcing material of choice for belts used in any type of food processing equipment.
Adding Kevlar as a reinforcing agent in timing belts creates a non-slip belt. It will also assist in reducing chatter and vibration through the system, extending the life of other parts and components, including the pullies.
Kevlar has a tensile strength of approximately 400,000 pounds per square inch, which means it can withstand most applications well beyond what standard steel reinforced belts can handle. It is also a material with a low elongation factor, adding to the durability of these Kevlar timing belts even when there may be concerns about shock and over-capacity loading in the application.
To add to the advantages, Kevlar timing belts are also resistant to corrosion. This makes them an ideal choice in food processing systems and machinery as they are durable even in high moisture types of environments.
