RUBBER BELT PRODUCT GUIDE MEGADYNE, headquartered near Mathi Italy, is a global manufacturer of rubber and urethane power transmission, product handling and linear positioning drive belts. Megadyne was founded in 1957 when Mr. Corrado Tadolini developed the first Megapower cast urethane belts. Moving on from Power Tranmission Belts, Megadyne developed processes to extrude thermoplastic linear timing belts and truly endless belts. In recent years, Megadyne has grown both organically and through various acquisitions, to create a strong portfolio offering power transmission belts, conveyor belts, specialty belts, pulleys and state of the art fabrication facilities. Today, Megadyne is recognized as a leader in materials and product development; where innovative ideas coupled with leading edge manufacturing processes solve belting challenges in power transmission, product handling and linear positioning/lifting across a broad number of industries and applications. With manufacturing, distribution and fabrication capabilities in Europe, America and Asia, Megadyne is well positioned to be your partner in design, where tomorrow's solutions can be delivered today.

Industry standards require that to accurately measure a belt, it must be installed on a fixture with two pulleys of prescribed dimension and tensioned to a specific value. Accurate values cannot be measured by hand on a free length of belt. WRAPPED V-BELT RAW EDGE V-BELT 1 2 3 3 4 4 5 BELT CONSTRUCTION 1. Rubberized Fabric Cover Cover envelops entire belt and protects the belt core. 2. Top Fabric Provides heat & oil resistance. 3. Load Carrying Section Cords/Tensile Members give ability to transmit power and ensure uniform load distribution. 4. Compression Section Elastomer resists compression fatigue and dissipates internal heat build-up. Provides firm lateral presure against sheave/pulley sidewall and distributes the load to the cords. 5. Precision Molded Cogs Provides additional flexibility, allows for use of smaller pulley diameters, aids in heat dissipation.

Technically speaking, "timing belt" refers to the trapezoidal tooth standard timing belt. Standard timing belts represent the original, older tooth profile technology. Newer, improved tooth profiles (curvilinear and parabolic) combined with superior upgraded tensile members (cord) and compounds exceed the performance of standard timing belt allowing much higher horsepower and torque to be transmitted, often in a smaller, more compact, overall drive space. The drive space can be more compact with curvilinear and parabolic belts because their higher horsepower capabilities allow the use of a narrower belt width. Even though the newer curvilinear and parabolic tooth profiles are preferred for higher horsepower/torque applications, trapezoidal belts are still widely used in drives where precise registration is required.
