Do you still need to play if the left and right values of dynamic balance are the same?

Hello: If the left and right numbers are zero, you don't need to type.

If the left and right numbers are other numbers, they will be played. Until you hit the left and right zero, it's fine. Otherwise, the tire dynamic balance is still not done well.

Adjustments still need to be made.

I guess you're talking about the dynamic balance used for tire leveling.

The dynamic balance value detected on each side indicates the dynamic unbalance value of the current test tire and wheel hub together, and the smaller the value, the better.

Although the detection value on both sides is the same, it does not mean that the dynamic balance of the tire hub on each side has been adjusted.

Therefore, it is still necessary to reduce the dynamic balance value to a low enough level by increasing or decreasing the balance weight.

Dynamic balance is to achieve the minimum value, not just look at the same.

Hello, the dynamic balance is said to be the value of each round, the standard is 0, I hope to help you, I wish you a happy life [car questions, ask the car master. 4S shop professional technician, 10 minutes to solve. 】

New tiresBalancingThe data is generally normal between 0-5, and the reasonable dynamic balance of car tires can have better stability when driving, and at the same time, there will be better safety guarantee during driving.

Attached: Automobile dynamic balancing:

1. When doing the dynamic balance of tires, the balance weight must be there, although the tires and wheels are round, but there will be a slight difference in the distribution of weight, which is also one of the reasons why the wheels will be unbalanced when running at high speed, and the owners will feel the steering wheel when it is serious.

There will be a jitter staring. Therefore, the balance hole is a necessary object.

2. When the vehicle is in the dynamic balance, the old balance block used before needs to be removed, the reason why the dynamic balance is needed is because the tire is in an unbalanced state, in the process of driving the vehicle, there will be deformation, the phenomenon of the balance weight falling off, in order to make the dynamic balance data more accurate, we must remove the original balance block when we do the dynamic balance.

3. When the owner changes the tire, repairs the tire, changes the wheel hub and other operations, it is best to do a dynamic balance, if the balance data of the tire is abnormal, not only will there be a feeling of steering wheel shaking when driving at high speed, but also to a certain extent, it will produce tire eccentricity, damage to the suspension, etc.

1. The steering wheel of the vehicle is driving at high speed.

Or the body shakes, this fault may be you four-wheel dynamic balance.

Bad caused.

2. After the vehicle tires are repaired, it is necessary to do dynamic balancing. It depends on the form of tire repair, there are two forms of tire repair, one is to remove the tire on the hub of the tire to repair the tire, there is hot glue.

Tire repair, cold glue tire repair. Mushroom nail tire repair. These 3 forms are the dynamic balancing of tires. Another is that you don't have to remove the tire from the hub to repair it.

This method of repairing tires is called self-repairing strips. This form does not require the dynamic balancing of the tire. If the dynamic balance of the wheels is not good, the front wheels will cause the steering wheel to shake at high speeds. If the rear wheels are used, the body will shake at high speeds.

3. It is necessary to do the dynamic balancing of the vehicle after replacing the tires.

If your car has the following situations, it means that your car needs to be dynamically balanced.

BalancingThe value is normal at 5 grams and below, but in actual operation, according to the different speed of the vehicle, it is generally believed that the ordinary car does not exceed 10 grams is normal, and the detection error of the dynamic balancing machine itself is different depending on the model.

The wheels of a car are made up of tires and hubs, but due to manufacturing reasons, the mass distribution of all parts of this whole cannot be very uniform. When the wheels of the car rotate at high speed, the dynamic imbalance will be formed, causing the wheels of the vehicle to shake and the steering wheel to be in motion.

The phenomenon of vibration. In order to avoid this phenomenon or eliminate the phenomenon that has occurred, it is necessary to make the wheel correct the balance of each edge part by increasing the counterweight under the dynamic situation, and this correction process is often called dynamic balance.

If the tires are not in a balanced state when rolling, they can be felt when driving, and the main feeling is that the wheel beam will beat regularly, which is reflected in the car is the steering wheel shaking. The installation position of the tire, the manufacturing process of the tire, or whether the wheel hub is deformed, etc., the tire repair will also cause the dynamic balance data to be too large, if it is a new tire and a new wheel, the tire gas is deflated and re-inflated, so it is necessary to regularly check the dynamic balance of the car.

The data requirements are up to the minimum G4000, the unit is gram millimeter kilogram (gmm kg), the International Organization for Standardization (ISO) in 1940 developed the world's recognized ISO1940 balance level, which divides the rotor balance level into 11 levels, each level in multiples increments, from to G4000, representing the eccentricity distance of the unbalance on the rotor axis.

Modern balancing technology was developed at the beginning of this century with the advent of steam turbines. With the rapid development of industrial production, rotating machinery is gradually developing in the direction of precision, large-scale and high-speed, which makes the problem of mechanical vibration more and more prominent. The severe vibration of machinery will bring a series of hazards to the machine itself and its surrounding environment.

While there are various causes of vibration, it is generally accepted that "unbalanced forces" are the main cause. According to statistics, about 50% of mechanical vibrations are caused by unbalanced forces. Therefore, it is necessary to change the mass of the moving part of the rotating machinery, reduce the unbalanced force, that is, balance the rotor.

Precautions: 1. The prerequisite for on-site dynamic balancing is the determination of unbalance fault, as well as the determination of the number of balance surfaces and the completion of various preparations, so as to ensure the time-saving and labor-saving balance work. If the equipment has been shut down, replace the reflective tape.

2. Check whether the function of the balance instrument and the power supply are sufficient and the connection status of the cable.

3. The installation position of vibration sensor and photoelectric sensor should always remain unchanged.

4. Each time the data record should be accurate, and at the same time, the vibration amplitude and phase after the first test weight should be compared with the original record, if the change is not large, and it does not reach more than 20%, it means that the test weight is not suitable, and its size and position should be reconsidered.

5. The installation principle of the test weight block is: the installation is reasonable, and when the rotor is running, it cannot fall off, and it should also be easy to remove.

10 or less, you can, the lower the value, the better.

Balancing

Rotordynamics is the study of determining the location and magnitude of the unbalance generated by rotor rotation and eliminating it. The amount of unbalance causes lateral vibrations of the rotor and subjectes the rotor to unnecessary dynamic loads, which is not conducive to the normal operation of the rotor. Therefore, most rotors should be dynamically balanced.

In machine manufacturing or maintenance, balancing becomes a process.

High-speed rotating machinery is greatly affected by materials, impact, corrosion, wear, and coking will cause unbalanced failures to the rotor system of the machine. Vibration failures in rotating machinery are 70%** due to the imbalance of the rotor system. Usually, the maintenance personnel dismantle the rotor with large vibration, directly replace the impeller, etc., and run it after reinstallation to achieve the purpose of reducing vibration.

However, due to the original unbalance of the rotating parts, the vibrations sometimes exceed the standard allowable values even after the machine has been run. In order to prevent the destruction of the machine, threaten the safety of on-site personnel and ensure the normal operation of production, dynamic balance correction is required.

The data requirements are up to the minimum G4000, the unit is gram millimeter kilogram (gmm kg), the International Organization for Standardization (ISO) in 1940 developed the world's recognized ISO1940 balance level, which divides the rotor balance level into 11 levels, each level in multiples increments, from to G4000, representing the eccentricity distance of the unbalance on the rotor axis.

The wheels of a car are made up of tires and hubs. However, due to manufacturing reasons, it is impossible for the mass distribution of the parts of this whole to be very uniform. When the wheels of the car rotate at high speed, a dynamic imbalance will be formed, resulting in the phenomenon that the wheels of the vehicle shake and the steering wheel vibrates while driving.

In order to avoid this phenomenon or to eliminate the phenomenon that has already occurred, it is necessary to make the wheel correct the balance of each edge part by increasing the counterweight in the dynamic situation. This process of correction is often referred to as dynamic equilibrium.

It's a bit big and should be under 5 grams.
