Timing belts work with timing pulleys to transmit rotary motion between two parallel shafts. Ondrives.US’ timing belts provide long working life with quiet operation, and, unlike chains, require no lubrication.
We offer timing belts in a variety of profiles and configurations to pair with our precision timing pulleys; standard profiles include MXL, XL, L, 40DP, T, HTD, and GT2 timing belts. We can also manufacture custom timing belts that are tailored to your unique specifications.
Proven Timing Belt Technology
Ondrives.US timing belts are comprised of a tension member with an S-Z twist, durable body material, and, on some models, a protective layer of material on the belt’s teeth. The tension member provides resistance to elongation when tension is applied to the drive pulleys; tension members are usually made of fiberglass, polyester, Kevlar, or steel.
The body material protects the tension member from dirt, grime, oil, and moisture. Neoprene and polyurethane are the most commonly used body materials, but timing belts may also be made from natural rubber or other polymers.
The teeth of the timing belt are molded to surround the tension member, and are made from a shear-resistant material for optimum power transmission between the belt and the pulley. On neoprene timing belts, the teeth are usually jacketed in nylon for improved wear resistance and increased belt life.
Timing Belts & Idlers
In an ideal motion transfer system, the center distance between the pulleys will be adjustable, so that the timing belt can be adjusted without the use of an idler. While idlers are components of many synchronous pulley and belt systems, they tend to induce more bending in the timing belt, which reduces belt life compared to a system with adjustable center distance.
Custom Timing Belts
Our standard timing belts (MXL, XL, L, 40DP, T, HTD, GT2) are designed to match the profiles of our timing pulleys. However, if none of our stock belts are right for your application, we can provide custom timing belts that are manufactured to meet your requirements.
Custom timing belts are available in the same profiles and sizes as timing pulleys, and with a range of teeth counts. In shorter lengths, cog belts with nearly all consecutive number of teeth are readily available. Beyond choosing a custom belt width, custom cog belts are not recommended except for very specific application requirements such as environmental, material, and other requirements.
