Each owner of the car dreams that his "four-wheel friend" at any time worked absolutely and did not allow the failure during the movement. This desire is every car owner, however, to achieve this goal it is necessary to comply with a number of maintenance rules, which will allow maintaining a car in good condition and always on the go.

Elementary knowledge of the car device, symptoms of possible faults and the reasons for their appearance will allow you to detect and eliminate any problem. For these purposes, track the periodically the technical condition of each node and identify the slightest changes in their work. Much attention should be paid to the fuel and lubricant system, the quality of all sorts of liquids, gaskets, anthers, etc.

An important is the condition of the generator belt, which to a greater extent ensures the normal performance of the car. After all, precisely because of this simple device, the car is provided by electrical energy for the work of most of its systems.

Generator belt, belt device

The generator belt is a small piece of car that allows you to ensure its normal operation. Thanks to the generator belt, it is possible to transmit rotation from the crankshaft to the generator itself, which allows the sufficient amount of electrical energy to work all sorts of equipment and systems.

The generator belt is a simple rubber product and is one of the large number of vehicle consumables, which must be replaced in time according to the requirements of car manufacturers. The belt is an elastic rubber tape, with a malfunction of which the car will not have the ability to move independently. In order not to get into an uncomfortable situation, it is necessary to have the concept of a car device, the belt of the generator, its location and replacement methods.

Easy design and reliability allowed the use of rubber belts of generators in all modern cars. This method of transmitting the rotational motion of the shafts from one to another is the most reliable. However, despite this, it is necessary to conduct periodic visual inspections of the state of the rubber belt, since it has a limited service life and can be out of time.

To date, there are many distinctive designs of belts caused by using them in various types of engines. Thus, all models of vethelters of car generators may differ in length, thickness, width and their profile. If we take into account the factors that this rubber device is under constant strong load, it should be sufficiently strong and at the same time elastic to ensure reliable connection of the pulleys of the generator and the crankshaft.

Important moments, which has a direct impact on the quality and durability of the belt is its temperature resistance. Since it is in constant motion under strong voltage, it is subjected to significant loads and temperature effects. In order for rubber material to be rapidly stretching and wear under the influence of the most continuous loads, it should be quite reliable and sustainable to all influences.

The generator belt is made of special rubber, having inside a strong multi-layer base from special matter and very reliable polymer threads. And for more reliable contact, various types of belts have inside different design, allowing to increase the area of \u200b\u200bcontact and, accordingly, the reliability of the device. For greater reliability of the generator belt and that he has a number of other positive qualities, manufacturers pay a sufficient amount of attention to the development of new manufacturing technologies.

Types of generator belts

To date, there are a huge number of all kinds of generator belts used in engines of different designs. All parameters need to be given sufficient attention when choosing them in specialized automotive stores. The main parameters for assessing the quality of the belt and the choice of the optimal model is its length, width, thickness, and profile. The strength of the generator belt design allows you to withstand heavy loads during intensive work, while ensuring a reliable connection between the crankshaft rollers and the generator.

Today you can select the following types of belts for the generator:

• gear;
• polyclinic;
• wedge.

The generator's toothed belt has a shape similar to a gear. One side of the belt has teeth, which makes it possible to give this type the remnants of maximum strength and efficiency of rotation from the crankshaft pulley. This type of belts is used not only for the generator, but also for the timing.

The polyclinic belt is much wider than all kinds and looks like a 2-connected wedge belt. The entire inner side of the polyclinic belt has a certain number of longitudinal and parallel grooves.

The last look is a wedge, which is able to withstand significantly heavy loads. This type of belt has a trapezoidal form and is used to transmit rotation to one or several instruments.

How the generator belt changes during operation

In order to have the concept of whether the replacement of the generator belt has come or not, first of all it is necessary to conduct its visual inspection. To do this, dismantle the belt for the generator and study it in detail on the appearance of cracks, breaks and other signs of wear. In the absence of visible damage, the belt is checked on the degree of stretching.

The complete replacement of the belt begins with the weakening of its degree of stretch by unscrewing a special bolt. The bolt may have a different form, depending on the car model. Until that moment while the belt is in its place, it is necessary to accurately remember its location and draw an approximate scheme so that later not to forget to correctly install it in place.

In order to loosen the tensioning bolt, it is necessary to select the appropriate key size, after which it is necessary to define it in which direction it must be unscrewed. With a small rotation, the key of the protracted bolt belt should relax. Bolt must continue to unscrew further until the belt tension decreases to easy removal from pulley.

While the new belt has not yet been set to its former place, it is advisable to compare it with the old and make sure that they do not have differences among themselves. It often happens that the belt specified on the package has significant differences from the required car. During installation, it is also necessary to make sure that the belt tension is strength, since it is precisely this factor that has a direct impact on its life.

After installing the new belt, you need to start the engine of the car and give the highest possible load, turning on the far light of the headlights, air conditioning, heated seats, mirrors and glass, and also click on the gas pedal. With a proper strap of the leishes generator and other extraneous sounds from the motor compartment itself and the belt itself, it should not be observed.

Inspection of the belt to detect whistles

With intensive ride on the car, each of his owner will soon face with a large number of problems, each of which can lead to unpleasant situations. Lightly worn, or a damaged belt gear begins to produce a weakly expressed unpleasant whistle and immediately allocate the cause of its appearance very difficult. Most often the car owner faces the fact that the belt simply turns out to be worn out and hence the most unpleasant whistle appears. But to detect the problem and on time to eliminate it is also necessary.

The main reasons for the leaf of the generator belt

The car during the movement independently produces electricity, which ensures the stable operation of all electronic systems. In order for this to occur in each machine, a special device that is called the generator is used. During the movement, the generator rotor is constantly rotating under various loads and produces electrical energy for the car. The generator itself is activated due to the rotation of the crankshaft, and the rotation of the crankshaft pullee itself is transmitted to the generator thanks to a special belt.

Well inspected the belt of the generator, shot from the car, you can set some causes of the occurrence of the whistle. It is the visual inspection that allows you to accurately determine the reason for its occurrence, which in turn makes it possible to quickly eliminate the problem.

Many car owners believe that the reason for the appearance of a whistle from the generator belt is its worniness and to eliminate the problem, it is necessary to urgently replace this detail of the car. However, very often the driver's opinion about the cause of the whistle is erroneous. The reasons for the appearance of unpleasant sound from under the hood of the car are quite a lot and they must be considered carefully.

under the belt got butter, what to do how to eliminate

The car is a very complex mechanism that is capable of functioning normally with the exact interaction of a plurality of units of units among themselves. There is a lot of factors on it, one of which can be the cleanliness of the most important parts of the machine. Observing the cleanliness of the individual parts of the car's design, due to its periodic, you can get rid of a number of possible problems.

Under the hood of the car is the most difficult mechanism, from which it is often the normal work. In particular, a special fluid is used to lubricate some moving parts of the engine - engine oil. For various reasons, leaking oil can occur - this can be a disruption of the system tightness, the driver's carelessness when the oil is poured into the neck. In the event that the oil falls on the generator belt, or the pulley may appear a unpleasant long-lasting whistle.

Such a whistle is often independently passed throughout the long period of time. During the rapid rotation of the generator belt, especially if this occurs under significant loads, due to the lack of adhesion with the pulley surface, slipping occurs.

Such a malfunction leads to the appearance of unpleasant sound, as well as a partial reduction in the level of generating electricity. Eliminate such a malfunction can be very simple and even independently. To do this, we need to weaken the degree of belt tension and completely remove it from the pulleys. With the help of detergents, remove traces of oil from the belt surface, after which the traces of oil on the pulleys of the generator and the crankshaft thoroughly wipe. In conclusion, you must install the belt in the place in the reverse order.

weak belt tension what to do how to eliminate

Another reason for the occurrence of an unpleasant sound from the car's engine compartment may become weak tension of the generator belt. Each car owner understands well that the degree of tension should be within the normal range. It can not be strongly pulled, but also can not be left with a weak tension. Weak tension indicates the weakness of contacting the surface of the generator belt with the surface of the pulleys. This may cause the appearance of not only an unpleasant whistling, but also constant short-term car battery and accelerated wear of the generator belt itself.

In order to eliminate this reason for the appearance of a whistle, it is necessary to carry out a visual inspection of the installed belt and pressing your fingers to the belt, see the degree of its deflection. With a sufficiently deep deflection, pull the loose belt. In the event that the tension is already at the limit, it will indicate the wear of the belt and the need to replace it with a new one.

wrong pulley line what to do how to eliminate

Next reason for the appearance of an unpleasant whistling from the generator belt is the wrong line of the pulleys of the generator and the crankshaft. The fact is that both pulleys must be accurately on the same line and a slight deviation from the plane can and leads to permeating sound.

The reason for this can be broken, or a weakly protracted pulley of the generator or crankshaft. To eliminate such a problem, check the condition of the pulleys and tighten them if it is necessary. However, in case the generator belt was in a response state for a long time, it could lead to its rapid wear. In order to eliminate the problem, it should be replaced by the pulley of the generator or crankshaft.

hard (tight) generator belt, what to do how to eliminate

Do not forget about the following reason for the appearance of a leaf of the generator belt, which is difficult not to notice - the rigidity of the belt. Most often, such a problem is manifested in the cold season, when all the rubber parts of the car's design become more rigid. Elevated elasticity leads to the fact that the generator belt is not able to rotate normally and again appears on the surface of the pulleys.

Often, such a problem is by itself when the engine temperature rises, and the temperature and the belt itself increases due to the friction force. The belt softens and acquires a normal form, only after that the whistle stops. In order to eliminate this problem, it is recommended to replace the rigid belt of the generator to a new with higher quality. High-quality rubber will not become tough under what weather conditions.

the bearing has fallen, what to do how to eliminate

It is worth remembering that the rotation of the pulleys and the generator belt is caused by the normal work of bearings. In case of insufficient quality of the bearing, or work with an overly high tension of the generator belt occurs so that large loads begins to all parts of the pulley design. This is exactly what leads to the rapid wear of the bearing and the exit of it.

In addition to the rustling sound, the bearing appears, a whistle appears due to the displacement of the bonding of pulleys. Such a malfunction is most often determined by visual inspection, as well as to sound. To eliminate it, you need to weaken the belt of the generator, remove it, dismantle the old bearing and install a new one. Bearings are recommended to purchase in branded stores that are able to provide high-quality products. This will prolong the operation of the generator, pulleys, bearings and belt for significantly long period of time.

mud, dust and other technical fluid on the belt

During intensive work, the generator belt of any modern car is exposed to high loads. Almost in all cases, the generator belt whistle begins at the place of its contact with the surface of the pulleys, as a result of bad contact. Slipping on the surface of the pulley, the belt just produces that the most unpleasant and sometimes the annoying sound.

The engine compartment is part of the car, where the main elements of the car are grouped. Very often, there is a hub of the engine lubricating oil on other parts of the car. However, the oil is far from the only reason for the occurrence of the belt whisthes.

The reason for the occurrence of the whistles becomes not only the oil, but also other liquids - cooling, dirt, dust and moisture, falling from the road leaf from under the wheels of the car, etc. By visual inspection of the belt, the degree of its contamination and the presence of technical fluid on the belt surface is determined. To get rid of the annoying whistle, the belt is removed, after which it is to process it and the surface of the pulleys with the help of a detergent fluid. With the help of a dry cloth, it is necessary to completely wipe the surface from moisture, dry the belt and only after that install it back into place.

How to get rid of the belt whistle do it yourself, step-by-step instructions, possible options

In order to completely get rid of the cause of the emergence of the opposite sound from the belt, it is necessary to diagnose the cause of its occurrence, only after which it can be proceeded to eliminate it.

1. When a suspicious whistling, the car published from the engine compartment appears, first of all, turn off the ignition of the car engine and open the motor compartment itself.
2. Conduct a visual inspection of the belt without disturbing its position and degrees of stretch. It is necessary to inspect the belt for any pollution (oil, moisture, dirt, dust, other liquids), physical damage (oversight, discover the threads, etc.).
3. Both sides of the belt must be absolutely whole and without visible damage and other traces of dirt, dust, oil, coolant, etc. It is also necessary to examine the inspection and pulleys of the generator and crankshaft.
4. Very often the cause of the belt whisthes is the degree of its tension. The weakened tension significantly reduces its contact between the belt and the pulley, which in turn entails slipping and the appearance of a whistle.
5. In case of detection of a problem in a weakened belt, it is necessary to adjust the degree of its tension.
6. If the above methods could not eliminate the resulting whistle, then the alternator and crankshaft pulley should be well inspecting. One of the explicit signs of disturbed alignment can be slipping tracks in the polyclinic belt.
7. If during the inspection it was found that at least one of the pulleys is moving "eight", this may indicate its failure. In this case, it must be replaced with a new one.
8. After the above methods, if it was not possible to cope with the whistle, then the belt must be dismantled from the pulleys and to carry out a more careful inspection of it for possible damage and contamination on the inside of the belt. If there is no visible damage to the belt, then it is necessary to clean it with special means. If there are any damage on the belt, then it should be replaced with a new one.
9. Do not forget that it is necessary to clean the surface of the pulleys using special means. In any case, there will be moisture and dust from the road during the movement of the car.
10. Now you can install a pure belt on peeled pulleys. Next, it is necessary to adjust the degree of its tension and start the car. It should save the car owner from an unpleasant whistle from under the hood of the car.
11. If the cause of the whistle was not eliminated, then the reason can be either as the belt itself, or in the drives of the generator and crankshaft pulley. The problem can be wounded in the generator itself, stretch rollers, compressor GUR and air conditioning. It often happens that the lubricant in bearings and a number of other more serious reasons are thick.
12. In the event that it is not possible to find the cause of the whistle, it is not possible to contact the car maintenance station and give the car into a reliable hand of specialists. Auto mechanics will study in detail the car for the presence of possible defects and will be verdict on the need for repair work.

Advice Prope: Optimum degree of tension of the generator belt, where to find information for a particular car

Normal work is absolutely any modern car provides not only fuel, but also electricity generated during the movement by a special device - generator.

The crankshaft pulp of any car is connected using a rubber generator belt with pulley generators. Thus, the rotation of the crankshaft pulley is transmitted to the generator, where electrical energy is performed. In order for rotational movements to be transmitted as efficiently as possible, it did not take place the rapid wear of individual parts of the car, the tension level must comply with the stated requirements of the vehicle manufacturer.

In order to find out the required degree of tension, contact the service book that comes complete to each auto model. The book indicates the procedure for performing work on the replacement of the generator belt, as well as its tension. Often the design of the car providing the generator mounts in such a way that it is able to move in a certain range. Thus, we can, weaken the adjusting bolt, push the generator to the specified distance to exhibit the optimal characteristics of the belt tension.
