About this deal

These past decades, but especially in the last couple of years, V-belt systems have undergone tremendous technological development. Internal Combustion Engines (ICE) have downsized, while their output and the demands on product performance have continued to increase with the addition of air-conditioning and other comfort systems. This combination creates more rotational forces in the system, meaning that the V-belt has an ever more crucial role to play. To reduce the ensuing vibrations, which are even more prominent at lower driving speeds, automatic tensioners simply don’t suffice; overrunning alternator pulleys, tortional vibration dampeners, and other components must be integrated into the system. We’re zooming in on all these components in a series of articles. The previous one focused on overrunning alternator pulleys, and now we will discuss the Micro-V® belt. A Micro-V® belt for every application The Electricity Generation Industry: Segmentation, Sources, Process Overview, Machinery, Terminology, Environment and Safety For the headlamps, just align it with the dotted line in the middler and "shift" the brightest part into the center. How does this work? Micro-V belt-This is the belt running over all the pulleys in the system. Micro-V stands for V-shaped grooves on the belt surface. To accommodate bi-directional flexing (serpentine shape) while remaining strong enough to transfer the total force required by multiple loads, the belt has multi-groove (multi-v, poly-v, or multi-rib) construction. It is more efficient than the older multiple-belt system and may consume less space in the engine compartment. By using a single, wider belt instead of multiple, thinner belts, the belt may be put under increased tension without stretching. Also, the tendency of individual (multiple) V-belts to “flip over” in the pulley groove (at high RPM and/or when the belt stretches) is eliminated by using a single and wide micro-v belt.

It is suitable for use in hybrid vehicles or vehicles equipped with a belt-driven stop and start function. In these, the alternator can work as a starter (if certain conditions are met) and/or as a booster to provide additional power.

The tensioner

Stretch Fit Drive Systems demand highly engineered solutions. Gates® Micro-V® Stretch Fit® belts, with exclusive self-tensioning technology, were the first aftermarket belts engineered to fit like a glove and perform properly on these unique stretch fit drive systems. Gates continues to add coverage to this growing market segment. Used appropriately, a visual inspection is the key to diagnosing ABDS problems. Inside today’s compact engines, vehicle manufacturers often include a TVD inside the system in place of traditional crankshaft pulleys. The TVD’s rubber ‘damping element’ helps improve the drive NVH (noise, vibration and harshness) characteristics.

The Auxiliary Belt drive system (ABDS) should not be confused with the Timing Belt drive system (Synchronous Belt Drive System -SBDS) of the internal combustion engine. Timing Belt drive takes power from the crankshaft and drives the camshaft/s that in turn drives the inlet and outlet valves of the engine.Finally, the regular Micro-V® belt is an all-rounder designed for the direct replacement of 90% of the belts of the European fleet. This aftermarket engineering solution combines the latest OE technologies such as: Coordinate Measuring Machine: Working, Types, Applications, Advantages, Software, Sensors & Calibration Chirps are frictional vibrations, which are subsequently transmitted as noise. It’s often one of the symptoms of misalignment. If revving the engine makes the frequency increase, misalignment of the pulleys is likely.

Effect on lifespan of Micro-V® belts: the belt drive has changed significantly. From the simple ABDS drive system on the left, to the more complex system with smaller pulleys and shorter bends on the right. The ABDS drive, which used to be known as the fan belt, has evolved significantly over time. Because the number of pulleys and the power to be transmitted in the system have increased, a more flexible belt was needed. We now use Micro-V® belts instead of simple V-belts. Micro-V® belts have ‘sidewalls’: they consist of miniature V’s all linked together to guarantee an even load distribution. Another advantage of this multi-ribbed belt is that it saves space in terms of the length of the engine, as a simple V-belt could only handle two pulleys, or three at the very most. What is more: we now have a system of specific Micro-V® belts, adapted to every application. All belts in this range are made of EPDM rubber. 1. Micro-V® Unique Fit

Gates Micro-V® Unique Fit belts are specially designed to meet the needs of unique applications or problematic drives. Special belt constructions eliminate belt noise, reduce tension loss, and solve problem drive applications. Despite their outward similarities, these belts are not interchangeable. We cannot stress enough how important it is always to select the Micro-V® belt prescribed by Gates and to use the correct components. Ask your usual spare parts store for the vehicle data or consult the Gates Autocat catalogue. In the old engines, the belt (V Belt) simply connected the crank with the radiator fan, so that fan runs continuously with the engine even if engine cooling is not required. But over the years, as engines became more complex and advanced, the fans became electrical rather than mechanical. The fan V-belt drive was superseded by the micro-V belt drive those powers one or more additional components, such as the alternator, compressor, pump etc. It’s not uncommon to find more than one V-belt in the same engine depending on the application. For example, many of tractors, gen-sets, etc. engines still use traditional V-belt drive. a special belt construction eliminating belt noise, reducing tension loss, and solving problem drive applications Now that we have learned about the importance of the ABDS system in modern engines, It is worthwhile to note that with certain modifications the normal ABDS system can be utilized to create a micro-hybrid system. In a normal engine, the belt drives the alternator to change the battery. However, in BSG (Belt starter generator) system, the alternator is replaced by a special motor that charges the battery and also provides mechanical power to the system when required. Motor mode is exploited as an electric boost, where the BSG assists the ICE for transient accelerations. Moreover, this mode is also used for the start and stop function, through which the cranking of the ICE is performed without the need of a separate starter electric machine.
