TIMING BELTS ARE BECOMING INCREASINGLY PREVALENT IN MODERN DRIVE SYSTEMS, PARTICULARLY WITH THE GROWTH OF AUTOMATION.
Timing Belts can be best described as having integrally moulded teeth on the internal circumference, which make positive engagement with axially grooved pulleys. Timing belts are also known as Synchronous, or Positive-Drive, belts. The most important feature of a synchronous drive is that it offers a fixed speed ratio between the driver and the driven pulleys.
STD (SUPER TORQUE DRIVE) PROFILE TIMING BELTS
STD (Super Torque Drive) Profile Timing Belts.
STD belts have a modified tooth profile which gives a more positive engagement with the pulleys. This results in the forces being distributed more evenly throughout the tooth, giving longer belt life, and reducing the likelihood of teeth shearing off.STD belts are available in S2M, S3M, S5M, S8M and S14M profiles.
DOUBLE-SIDED TIMING BELTS
Now used extensively in textile units, printing and packaging machines; but the most common application would be for mower decks. See DS Timing Belts in Lawn & Garden section for more details.
HYBRID POLY-TIMING BELTS
Brawn-XT was primarily developed for the milling industry, and it is regularly found in flour and rice mills.
The belt is a double-sided drive belt, having timing belt teeth on one side and Poly-V ribs on the other. To bolster the tensile strength for this application, the belts are Aramid-corded and made with specific heat and abrasion-resistant compounds. Working temperature is from -35°C to +130°C. Ribbed profiles available – PK and PL. Timing profiles available – 5M, 8M, S8M
HIGH-POWER, HARSH ENVIRONMENT, TIMING BELT
Known in the industry as a Fin-Fan belt, Sentinel was developed to power Air-Cooled Heat Exchangers (ACHEs) – always regarded as one of the harshest environments for synchronous belt to operate in.
As well as having a higher power transmission capacity and higher tensile strength, these belts has impressive abrasion-resistant qualities.
PACKAGING MACHINERY TIMING BELTS
TopCoat XT is constructed with a timing belt drive component backed with a profile top made of application-specific rubber. The topcoat selection is based on the temperature and Shore hardness required and can be 4, 6, 8, or 10mm tick. The timing belt drive member is vulcanised with the top coat as a single piece and is available in L, H, 5M, S5M, 8M, S8M profiles.
The profile top is used to grip and cushion various material in conveying and packaging processes. Typically found in vertical form fill seal (VFFS) machines, ceramics industry, packaging lines etc.
HIGH-POWER, HIGH TEMPERATURE, TIMING BELTS
As well as having an extreme working temperature range, up to 130°C, Thermal-XT2 has a higher power transmission capacity compared to TorquePlus-XT2. It will run at higher angular speeds, is resistant to Ozone, and has very low noise characteristics.These belts are available in 5M, S5M, 8M, S8M, and 14M sections
