Product representation

1. Detailed product information

1. The principle of work

The Weichai belt tensioner uses a built -in spring or hydraulic mechanism to automatically determine the changes in the belt tension. If the belt weakens due to wear, temperature changes and other factors, the tensioner will make a constant and stable force to force the tensioner wheel to move, so that the belt will always maintain the appropriate tension, providing an effective and stable power transmission, preventing the belt slip and guaranteeing normal the operation of the auxiliary units of the engine (such as the generator, water pump, compressor air conditioning, etc.).

(II) structural composition

The tensioner: He is in direct contact with the belt. Usually it is made of high -strength aluminum alloy or high -quality steel. The surface is specially processed to ensure good wear resistance and low friction coefficient. It can effectively reduce the wear of the belt and extend its service life.

Spring mechanism/hydraulic mechanism: the main component that ensures the strength of the tension. The spring type tensioners create tension due to the elastic deformation of the spring; Hydraulic tensioners use hydraulic oil pressure to achieve tension. Compared to spring -type tensioners, hydraulic tensioners are more responsive and can better adapt to difficult working conditions.

Bracket: serves to fix the tensioner, made of high -strength material to ensure stability in the vibration of the engine and difficult operating conditions, as well as to ensure the normal operation of the tensioner.

(III) The advantages of the product

Accurate tension: it can automatically and accurately adjust the belt tension in order to adapt to changes in the expansion and compression of the belt in various working conditions, ensuring stable power transmission and reducing power loss.

Reliable and durable: the main building is made of high -quality aluminum alloy, internal friction parts are made of imported raw materials and agreed with branded bearing parts. It has the characteristics of high wear resistance, high heat resistance, low noise, low vibration and super -long service life, and can also adapt to complex and harsh working conditions.

High adaptability: it is specially developed in accordance with various operating conditions of the engine, is fully adapted to various types of engines, and has good versatility.

Reliable quality: in the production process, the appearance, height of the center and the output torque are checked online. Each product is printed with a unique identification code to ensure information traceability.

2. Stages of installation

Preparation: Make sure that the car engine is turned off and cooled down, and prepare the necessary tools, such as the hook key, an open key, a special tensioner, pliers, etc. If the space in the engine compartment is limited, the hood can be omitted for ease of use.

Remove the old tensioner and belt: if the tensioner has a locking device, first unlock it; Use a special tool or wrench to loosen the tensioner to loosen the belt, carefully remove the old belt from each wheel, and then remove the old tensioner.

Install a new tensioner: install a new tensioner in the indicated position, making sure that the bracket is securely fixed, and the bolts are tightened with the indicated puff moment.

Install a new belt: put on a new belt to each pulley, pay attention to the direction of the belt, make sure that it is combined with the recesses of all the teeth of the gears, and the belt is correctly located in guide pulleys and guide grooves.

Adjust the tension: use a tension tool or wrench to adjust the tension in accordance with the standards specified by Weichai. Usually this can be checked by pulling the middle of the belt, which ideally should easily bend at about 15-30 degrees.

Checking and testing: check the belt again to make sure that it is installed correctly, not twisted and not weakened, and make sure that all tensioners and fasteners are correctly installed and tightened; Before starting the engine, make sure that all parts are installed correctly; Run the engine and check if the belt moves smoothly and whether there are no extraneous noise or vibration.

3. Common malfunctions

Unusual mechanical noise from the tensioner: noise mainly comes from bearings and internal damping mechanisms (springs and damping blocks, etc.). Possible reasons: breakdown of the supporting plate or contact with other parts due to improper installation or excessive adjustment; cracking of aluminum parts, this can be caused by improper installation and adjustment, the synchronization pointer is not combined with the position, which leads to clashes on the left and right; Damage and deformation of the pulley, this can be caused by the improper installation of the tensioner, which leads to an inclination of the tensioner or the non -parallelism of the surface sliding and tensioner sliding surfaces; deformation of the adjusting plate, this can be caused by improper installation and adjustment, contact with other parts; Damage to the spring, this can be caused by the improper installation of the tensioner, which leads to a prolonged overload of the spring, the contact of the spring with the internal details of the tensioner and the fatigue destruction.

Bearing of the bearing: the probability of occurrence is low, but if this happened and was not eliminated on time, this will lead to damage to the timing belt. In severe cases, the engine valve will be bent with a piston. The main reasons are improper installation and adjustment, design damage and breakdown of parts that interfere with the work of the bearings, or unstable engine operation, causing excessive shock load on the bearings.

Abnormal noise in the gear gear: abnormal noise occurs when the engine is operating, which can be caused by a bearing malfunction, which leads to a roar or a sharp high -frequency sound; The tension of the stretch roller system is too large, and the gear transmission makes a buzzing or ringing sound during operation; The tension of the stretch roller system is too small, and the gear transmission makes the sound of a belt strike during operation; When the tensioner’s tensioner is operating, it sways too much, the belt vibrates greatly and makes an abnormal noise; The stretch mechanism makes a knock during operation.

Stages of installation ：

Preparation: Before starting installation, make sure that the car engine is turned off and cooled down. This is an important condition for ensuring personal safety and prevent damage to the engine components. Prepare all the necessary tools, such as hook keys, claws, special tension tools, pliers, etc. If the space in the motor compartment is narrow and inconvenient for operation, you can consider lowering the engine hood to expand the working space.

Remove the old tensioner and belt: carefully check the tensioner. If there is a blocking device, first unlock it. This step is very important, otherwise the tensioner or other components can be damaged during disassembly. Using a special tool or wrench, weaken the tensioner in the right direction and gradually loosen the belt. After the belt is weakened, carefully remove the old belt from each pulley, avoiding the application of excessive force, which can damage the belt or components of the wheeled gear. After completing the belt, remove the old tensioner and save the removed bolts, nuts and other small details so as not to lose them.

Install the new tensioner: Install the new tensioner in the installation location intended for it, making sure that the connection between the bracket and the motor block is exactly aligned. Use the bolts of the specified specifications and tighten them in a specific sequence and according to the torque requirements to ensure that the bracket is securely secured. During the tightening process, a torque wrench can be used to measure accurately to ensure that the tightening torque of each bolt meets Weichai technical standards, preventing the tensioner from loosening due to insufficient tightening force or damaging the tensioner or motor housing due to excessive tightening force.

Install the new belt: First, put one end of the new belt on the corresponding wheel, and then put the belt on each wheel one by one according to the correct direction of the belt. When installing the belt, special attention should be paid to aligning the belt with the notches of all gear teeth, as well as the correct position of the belt in the guide pulley and guide groove. If the belt is not installed correctly, it can cause it to slip or deflect during operation, which will affect the life of the belt and tensioner, or even damage other parts of the engine.

Adjust the tension: Use a tension tool or wrench to adjust the tension according to the standards specified by Weichai. This can usually be checked by pulling on the middle part of the belt, which should ideally bend easily by about 15 to 30 degrees. When adjusting, gradually increase or decrease the tension and monitor the degree of bending of the belt to avoid over-adjusting at one time. Too much tension will increase the wear of the belt and gear parts and shorten their service life; Too little tension can easily cause the belt to slip and affect power transmission.

Inspection and Testing: Once the tension adjustment is complete, check the belt installation again to ensure that the belt is not twisted or loose and that all tensioners and fasteners are installed and tightened correctly. Before starting the engine, be sure to make sure that all parts are installed correctly. This is the last line of defense to ensure the normal operation of the engine. Start the engine and check the condition of the belt to make sure it is smooth and free of extraneous noise or vibration. If any abnormalities are detected, immediately turn off the motor, check and adjust.
