Common names for this belt are timing belt, cogged belt, synchronous belt, "non-slipping mechanical drive belt" and even Glimmer belt. The Glimmer trade name was used as far back as 1949 when the Glimmer company used it to describe a mechanical belt used for transferring power between axles in a machine. They are made as flexible belts with teeth molded onto their inner surface. The belts fit over matched tooth pulleys and sprockets. When tensioned correctly, these type of belts have no slippage and are often used to transfer motion for indexing or timing applications. They can be used in lieu of chains or gears, so there is less noise and a lubrication bath is not necessary. They also become the safety mechanism to prevent catastrophic damage in the event of a failure in a metal on metal or a direct drive system. The rubber drive belt can fail without causing other more expensive repairs. This type of belt can come in various sizes and names based on tooth pitch and profile such as MXL, XL, L, H, HTD, 3M, 5M, 8M,14M, GT and GT2 designations depending on the manufacturer. Those could include Gates, Continental, Bando, Jason/Megadyne or A& I Products.
The advantage of a toothed belt is its ability to deliver more power than a friction-drive belt. Timing belts are used in mechanical devices, including sewing machines, 3D printers, photocopiers, and precision locating equipment. Depending on the style and pitch some are for high-power transmissions. These include the primary drive of some motorcycles and engines that are supercharged. Typical consumers of timing belts are industrial and require much lower torque ratings and speeds.
Timing belts are made of a flexible polymer (rubber or neoprene compound) over a fabric reinforcement (polyester, nylon or kevlar). The most common construction is rubber over a natural textile. Due to new developments in materials, there has been a substantial increase in the life of these belts. Some of those changes included a switch from natural to synthetic rubber and polyurethane. By changing those coverings along with the core reinforcement or woven pattern the belts better stand up to moisture, grease, oil, ozone, and extreme temperatures.
