Toothed belt drives are always used where synchronous and smooth power transmission should be ensured.
Various typs of toothed belts and toothed belt pulleys are available from norelem:
The version T (T5 & T10) is the standard version. This is the toothed belt type with the classic trapezoidal profile as depicted in DIN 7721. This sort of drive is often used because it combines inexpensive and reliable properties.
The version AT (AT5 & AT10) is the reinforced version for transferring higher torques. The higher stiffness of AT toothed belts requires that larger diameter pulleys are used than with T toothed belts.
The High Torque Drive (HDT) toothed belts with rounded teeth ensure more consistent tension curve. HDT toothed belts are especially suitable for precision tasks.
Here is an overview of the advantages of a toothed belt drive:
- low wear
- almost maintenance-free
- good resistance to fats, oils and many other chemicals
- high power transmission (AT & HTD)
- low belt elongation
- operating temperature range between -30 °C and +80 °C (T & AT)
The toothed belts are made from polyurethane. The combination of elastomer teeth and steel reinforcement cords ensure high power transmission. Polyurethane belts are maintenance-free, low-noise, robust and extremely durable. In addition, this material enables ca. 30% more output with smaller dimensioning of the drive as by classical T and AT toothed belts. The toothed belts provide high power transmission in various industrial applications such as machine tools, industrial robots or packaging machines. The endless belts are available in the standard length range of 165 mm to 2250 mm.
