What Are Accessory Belts?
As their name suggests, accessory belts take rotational power from the engine's spinning crankshaft and transfer it to various pumps that run devices and accessories on the vehicle. Without accessory belts, your A/C compressor wouldn't be able to pressurize refrigerant that cools the cabin in summer. You'd have a hard time turning the steering wheel too, since the power steering pump wouldn't have the muscle to provide assistance. However, you wouldn't have to suffer wrestling with the steering wheel in the heat for long because your battery would quickly die without the alternator to maintain a constant charge level. But before that even happened, your engine might overheat because coolant might not be circulating (if the vehicle's water pump is externally mounted) or a belt-driven radiator fan wouldn't be spinning.
What is the V belt on a car?
On the left is a typical accessory V-belt found on older vehicles. On the right is a closeup of a typical multi=grooved or ribbed belt. Yes, accessory belts help get a lot of essential work done. And there's no arguing that your engine and electrical system could not run without them.
What is serpentine belt tension?
Unlike individual belts, tension on a serpentine belt usually comes from a tensioner pulley that's spring loaded to provide constant pressure so that the belt stays tight.
How to tell if belt is worn out?
Signs Of Belt Wear. As rubber compounds in all accessory belts age, they'll eventually start to crack, fray at the edges, become hardened and glazed, crumble - and ultimately break. Here are some telltale signs your belts are wearing out.
What is the space saving belt on a car?
A space-saving answer found on most modern cars and trucks is the serpentine accessory belt.
What does it mean when a belt cracks?
If a crack reaches more than halfway through an accessory belt, it's likely to break very soon. When accessory belts wear out, chunks of rubber are likely to break off. On the underside of the belt that contacts the pulley wheels, cracks on 3 or more ribs next to each other in any 1-inch section indicate a worn belt.
How much movement does a tensioner arm need?
Generally, a tensioner in good condition will create a smooth-running belt with only slight vibrations and minimal movement of the arm piece ( approximately 1/32nd of an inch). A tensioner arm that allows a jerky wobbling motion of the belt or shifts more than 1/4th of an inch needs replacement.
What is a wide V belt?
So-called wide V-belts with a height-width ratio of over 1:2 are used for heavy power transmissions and for applications where large speed changes occur. Therefore they are also referred to as variable speed belts.
What is a flat belt?
Flat belts. The simplest type of belt is the flat belt. It has a rectangular cross-section and was often made of leather in the early days. Today, however, steel or high-strength synthetic materials such as polyamide or aramide are used for tension cords. These force-transmitting cords are embedded in a rubber core between a top cover ...
Why are variable speed belts used?
Variable speed belts are usually cogged to reduce flexural stiffness. Such belt types are used in continuously variable transmissions in which the pulley diameter is changed by an axial shift to adjust the transmission ratio.
Why are V belts raw?
Due to this missing of the relatively stiff sheathing , raw edge V-belts thus have better flexibility. In addition, the force transmission from the pulley to the tension cords does not take place through the sheathing but is transmitted directly throught the core. This results in increased power transmission. To improve the transverse rigidity, elastomer fibres are incorporated transversely to the running direction of the belt.
Why are V belts cogged?
However, the increased belt thickness has an adverse effect on the flexibility. To compensate for this and to be able to use narrow V-belts even with relatively small pulley diameters, they are therefore cogged (so-called narrow cogged V-belts). This increases flexibility even with strong curvatures. This is why narrow V-belts are usually found in the raw edge version.
How to determine transmission ratio of a V belt?
While the transmission ratio for flat belts is determined by the outer diameter of the pulleys , in the cas of V-belts the so-called pulley pitch diameter must be taken as a basis for calculating the transmission ratio due to the special geometry. The pitch diameter d is defined by the nominal belt width b w. The nominal width corresponds to the belt width at the level of the neutral axis. Thus, according to the definition of the neutral axis, the nominal width always remains constant even when the belt is bent (i.e. when rotating around different pulley diameters).
Why are V belts better than flat belts?
Due to the greater belt thickness of V-belts compared to flat belts, the energy required to bend the belt around the pulleys is higher. Therefore, V-belts have a slightly lower efficiency than flat belts (approx. 95 %).
