Automobile belt is a kind of rubber product. With the increase of their working time, automotive belts and related accessories will wear and aging. Therefore, it is very important to correctly and timely understand the use status of automobile belts. Next, let's talk about how to identify the damage of the belt from the sound and appearance.

1.Listen to the sound to see if it's good or bad

When the belt squeaks, it generally means that the friction coefficient of the belt surface is greatly reduced, and the belt has been excessively worn. If there is a noise when the vehicle is under load, you may wish to observe one of the transmission belts, and you will find that the resistance or elasticity of the automatic belt tensioner or the belt elastic wheel will increase abnormally. When you hear the belt rumbling, it means the belt is shaking. This situation occurs generally because the drive belt is too loose and stretched too long, or the belt tensioner and elastic wheel are damaged.

2. Watch the belt change

The belt becomes longer: The first step to check whether the belt is normal is to check the belt tension. Use your fingers to strongly press the middle of the belt pulley. If the pressure is about 10kg and the belt reduction is about 10mm, the belt tension is just right. If the amount is too large, it means that the belt tension is insufficient. The cause of the insufficient tension may be that the fastening wheel is loose, or the belt has become longer. If the belt becomes longer, it means that the belt has been deformed and needs to be replaced in time.

Loose belt cracking: If the belt is found to have reduced hardness, abrasion, fiber breakage, cracks, burrs, etc., it indicates that the belt has been damaged and cannot be used.

Summary: Counterfeit and inferior belts will not only affect the normal operation of the engine and accelerate the damage of the vehicle, but may also affect the driving safety of the driver. Therefore, for our own safety, we must carefully discern when purchasing belts, compare them carefully, and must purchase them from regular automotive belt manufacturers. At the same time, in the daily use process, it should be timely maintained and discovered in time.

For car owners who are familiar with machinery, the most difficult part of replacing the automotive v belt is to adjust the belt tension. The tension should not be too loose or too tight. Whether the belt tension is suitable or not depends on not slipping when dragging a certain torque. Improper maintenance, improper installation due to lack of tools, and worn pulley grooves or worn side belts are all causes of improper tension. Therefore, the following steps should be taken when selecting automobile triangle belts:

(1) Make sure that the car and the fan cannot be started when the belt is replaced.

(2) Loosen the installation lock column and adjusting bolt, and move the generator to remove the old V-belt.

(3) Put the new V-belt on the pulley. Never use a screwdriver or a spudger to pry the belt onto the pulley. Doing so will lose tension and shorten the life of the belt.

(4) After inserting the V-belt into the wheel groove, move the parts of the generator and the generator body that are not easy to pry, and then tighten the adjustment bolt.

(5) Consult the maintenance manual, car manual, and V-belt product instructions, and select the appropriate tension.

(6) Use the tension gauge to accurately measure the tension of the belt. The finger pressure method is not as accurate as the tensiometer. In modern engines, the tension of the belt is relatively high, that is, the belt pulley bears a greater tension, the distance between the belts is shorter, and the belt cross section is less. Therefore, the tension estimated by the feeling is different from the actual tension. Shiatsu is a subjective method of measurement, which varies from person to person. When measuring by finger pressure method, different models have different requirements.

(7) After running the belt for 15 to 20 minutes, make the belt fit the pulley groove, and the tension will be relaxed. Therefore, the belt must be adjusted again.

The models of different brands have different belts because of different engine models. Generally, there are four types of belts: generator belts, air compressor v belt, booster pump belts, and timing belts. The belts of air conditioners and booster pumps of most models are the same, because the number of grooves of air conditioner pulleys and power pump pulleys is the same, and the same type of belt can be used for both. The generator belt is generally a single piece, but it also varies from car to car. There are also many types of generator belt, air conditioning belt, and power steering pump belt that are all in one. There is only one long belt that runs through all the pulleys.

The belt is an important accessory for the normal operation of the engine. Without a belt, there is no transmission of energy. Therefore, when we usually use the car, we must regularly check the wear of the belt. There are grooves on the inner side of the belt, which is also a sign to distinguish the belt model. Generally, it depends on how many grooves the pulley has. For example, if the belt has 5 slots, the belt must be 5PK; if the belt has 6 slots, it must be 6PK. On the front of the belt, there is generally the name of the belt model. We mainly look for the two letters PK. The number in front of P represents the groove number of the pulley, and the number after K represents the length of the belt. If the front number of the original car belt cannot be seen, then the specific belt model can also be determined based on the engine model. Don't worry about this.

Regular inspection of the belt can avoid accidents. When the car is running at high speed, it is still very dangerous for the engine to lose kinetic energy due to the broken belt segment. Usually you can often observe the depth of the belt's clamping groove. If the depth is very shallow, it is easy to cause skidding. Then check the edges of the belt to see if there are any gaps or breaks. Once found, it should be replaced in time.

As an important part of the operation of the car, the belt is connected to various parts. Once it breaks or slips, the related air-conditioning compressor, power steering oil pump, alternator, etc. will be adversely affected. Therefore, it is very important to master the identification method of the automobile belt, and it is also important to know the replacement cycle of the belt. The following are some methods for identifying the quality of automobile belts and determining whether the belt is damaged.

How to identify the advantages and disadvantages of automobile belts?

1. Smell

True: No odor

False: There is a pungent smell of smelly gum.

Smelling is the first step in the identification of the advantages and disadvantages of automotive belts, and it is also a relatively effective trick. Often inferior rubber products will have a pungent smell of gum. The car owner can distinguish it with just a little attention.

2. Take a look

For the same reasons as above, counterfeit products usually make a fuss about materials and processes in order to save costs. The products produced are generally rough, and the printed fonts are relatively vague.

3. More comparison

A repair shop or store that sells counterfeit and inferior belt products will usually have the same specifications but several prices. It is recommended to make a careful comparison of these products with different prices before choosing.

Suggestion: The best way to deal with counterfeit and shoddy products is to choose regular purchase channels. The genuine parts of most automotive belt manufacturers are only sold through regular companies to distinguish counterfeit and shoddy goods from the gray market. Genuine products are not sold through unauthorized distribution channels. Therefore, it is best to choose the corresponding regular store when replacing the car belt.

It should be noted that the timing belt is not the only rubber material. Some models use a metal chain for the timing belt, which is the timing chain in our mouth. The replacement cycle between them must be different. Generally speaking, the replacement cycle of the timing chain is longer than that of the timing belt, and the replacement cost will be higher.

Timing chain

Even if they are all timing belts, the replacement cycle will vary from model to model. Usually the car timing belt replacement cycle is around 60,000 kilometers, and the general timing chain is free of replacement, and a few need to be replaced is also more than 100,000 kilometers. However, the specific time is subject to the calibration cycle of each model. The car owners can check it through their car maintenance manual.

Timing belt

Of course, the specific replacement cycle not only needs to refer to the replacement requirements of the vehicle model, but also needs to be adjusted according to your driving habits and maintenance habits. In addition, when the timing belt needs to be replaced, the related accessories will also be replaced together. Unless serious quality problems occur, the accessories will need to be replaced together when the timing belt is replaced.

When changing the engine belt, be sure to align the timing before removing the timing belt. Only when the timing is correct can the tensioner be removed. Only then can the belt be removed. Try not to get the mark wrong when installing the belt. After installing the belt, use a wrench to turn the crankshaft twice, and then look at the mark. If the mark is correct, install other things on the top. Now most cars are easy to top the valve, so the timing mark must be correct. Replace on time according to the requirements of the user manual.

If you feel that you can't solve it, you can go directly to the repair shop to get the , and you must choose a regular repair shop. Because the small repair shop does not have any quality assurance, it may also lead to consumers being deceived.

With the rapid development of society, more and more families or individuals have purchased cars. But as the saying goes, you can’t afford a car from buying a car, and you can’t repair a car from affording a car. Why? Because everyone is poor in car maintenance knowledge of various parts of the car.

Knowledge and recommendation for the purchase of belt:

Most friends will think that in theory, the car should be able to drive 100,000 kilometers or more, or drive for three to five years. This is actually wrong. The belts are all rubber parts. Everyone knows that rubber will age.

The general use period of automotive timing belt is 2 years. The high temperature when the engine is running, the cooling when the car is stopped, the greasy impurities, the matching of the timing belt tensioner and the incorrect method during installation will lead to a shortened service life of the timing belt, so it caused another problem of kilometers. New car timing belts generally run 80,000-100,000 kilometers. After the timing belt is replaced, the service life of the belt will also be reduced due to the depreciation, use, and equipment of the car. Therefore, it is best to replace the timing belt in time.

Everyone needs to always pay attention to some things to replace the purchased belt:

When changing the belt, please pay attention to the correct operation of the operator in severe cold or scorching heat. Do not twist the timing belt hard. This will cause the internal fibers of the belt of the timing belt to break severely, which seriously affects the service life. When installing an automobile belt, the tensioner must be adjusted and cannot be pryed up directly with a wrench or hard object. If you see cracks on the outer surface of the timing belt and the rubber smell is very strong during use, you need to pay attention to whether the belt is aging. There are abnormal noises while driving, you need to pay attention to whether the car belt is installed correctly, or the quality and tooth shape of the belt are qualified, and match the generator timing pulley. Therefore, it is time to consider replacing the belt.

The functions of feeding mechanism of CNC lathe

The functions of feeding mechanism of CNC lathe: The automated feeding manipulator of NC lathe can imitate some movement functions of the human hand and arm, and is used to grasp and carry objects or operating tools according to fixed procedures. It can replace the heavy labor to achieve mechanization and automation of production, and can operate in harmful environment to protect personal safety. The automated feeding manipulator of NC lathe is usually used as an additional device of machine tools or other machines, such as loading and unloading and transferring work pieces on NC lathe.

The use of CNC machine tools instead of manual labor can save costs, improve efficiency and reduce the rate of defective. At the same time, it liberates the labor, makes the tedious work flow simple and easy to operate, and greatly reduces the labor cost.

What is the assistant manipulator? What is the purpose of the assistant manipulator?

What is the assistant manipulator? It is a new kind of auxiliary equipment used for labor saving in material handling and installation. It skillfully applies the balance principle of force to form a gravity-free floating state of materials in the air, that is, the gravity of materials is balanced by the corresponding control system, so that the operator can balance the movement and positioning of materials in space only by pushing and pulling the materials.

The assistant manipulator balances the gravity of the object through the thrust or pull force generated by the cylinder to achieve the assistant effect. By detecting the end fixture of the sucker or the manipulator and balancing the gas pressure in the cylinder, it can automatically identify whether there is a load on the manipulator arm of the manipulator, and automatically adjust the air pressure in the balancing cylinder through the pneumatic logic control loop to achieve the purpose of automated balance. When working, heavy objects are suspended in the air to avoid collision between products.

Basic knowledge of the automatic conveyor belt

The basic knowledge of the belt conveyor is mainly divided into: daily maintenance knowledge, conveyor limitations and conveyor operation rules.

First, what are the daily maintenance of belt conveyor?

1. check whether the belt is degumming.
2. check whether spring is loose or deformed and replaced.
3. check whether the motor has abnormal sound.

Second, what are the limitations of the belt conveyor?

The gradient of belt, the length of conveying material, the nature of conveying material, the width of belt, the running speed of belt, etc.

In addition, there will be special belts for different materials; for example, the belt with bucket slope can be close to 90 degrees, and the gradient of pattern belt can also be relatively large.

Third, what departments are widely used in belt conveyors?

Large ones for coal and mining; small ones for electronics and electrical appliances, and some for chemical industry, tobacco, plastic, etc.

There are also food industries, such as biscuits, bread and so on. The belt conveyor is only one kind of conveying equipment. Conveying equipment is widely used in industries, such as automobiles, household appliances and so on.

Four, operation rules of the belt conveyor

1.The fixed conveyor should be installed on a fixed basis according to the prescribed installation method. Before the formal operation of the mobile conveyor, the wheel should be wedges with triangular or brake. In order to avoid moving in the work, there should be a one-meter channel between the machine and the machine, and between the machine and the wall when there are several conveyors working in parallel.

2.Before using the conveyor, it is necessary to check whether the running parts, belt buckles and carrying devices are normal and whether the protective equipment is complete. The tightness of the tape must be adjusted to a proper level before starting.

3.The belt conveyor should start at no load. After the operation is normal, the material can be fed. No feeding before driving.

4. When several conveyors are connected in series, they should start from the unloading terminal and start in sequence. After normal operation, the material can be fed.
5. When the tape runs off during operation, stop and adjust it, so as not to use it reluctantly, in order to avoid wearing edges and increasing load.
6. The working environment and the temperature of the delivered material must not be more than 50 degrees centigrade and less than -10 C. It is not allowed to convey materials containing acid and alkali oils and organic solvents.
7. No pedestrians or passengers are allowed on the conveyor belt.
8. Before stopping, the conveyor must stop feeding before stopping the material on the belt.
9. The conveyor motor must be well insulated. Cable of mobile conveyor should not be dragged or dragged. The motor must be grounded reliably.
10. When the belt slips, it is strictly prohibited to pull the belt by hand to avoid accidents.

What are the advantages of automated loading and unloading?

There are three main advantages of automated loading and unloading.

(1)High production efficiency: To improve conveyor production efficiency, we must control the production rhythm. Except that the fixed production and processing rhythm can not be improved, automated feeding and unloading replaces manual operation, so that the rhythm can be well controlled, avoiding the impact of human factors on production rhythm, greatly improving production efficiency.

(2)Flexible process modification: We can quickly change the production process by modifying the procedures and gripper fixtures. The debugging speed is fast, and the training time for employees is not needed, so it can be put into production quickly.

(3) Improve the quality of work pieces: Use robot automated production line. From feeding, clamping to blanking, it is totally completed by robots, which reduces the intermediate links and greatly improves the quality of parts, especially the work piece surface is more beautiful.
