What are the daily maintenance methods for the joint v belt?
1. Correct installation
When installing the belt, the symmetrical center planes of the main and secondary pulleys of the unified circuit should be within the same plane, and the positional deviation should not exceed ± 3% of the center distance. Otherwise, it will cause the combined v belt to twist in the wheel groove, causing early wear on the side and reducing its service life.
2. Correct selection
The commonly used joint v belts come in different models. When replacing, it is necessary to ensure that the groove model of the original joint v belt or pulley is consistent, and the length of the replaced belt should also be consistent with the original length.
3. Clean oil stains
After the v belt is stained with grease, engine oil, and other oil stains, it is easy to slip and accelerate the damage of the belt. It should be cleaned in a timely manner with gasoline or with cleaning agents such as alkaline water, and oil cannot be used for operation.
4. Clean the belt and pulley
Wipe the triangular belt with a cloth dipped in a small amount of non volatile liquid. Do not soak in cleaning agents or use cleaning agents to brush the belt. Do not use sandpaper or sharp objects to scrape the belt.
5. Daily maintenance
Strictly monitor the operation of the v belt during use, check for any abnormal vibrations, and carefully listen for any abnormal noise. After running for a period of time, turn off the machine and check the heating of the bearings and motors.
What are the possible causes of damage to the triangular belt?
1. There are debris left on the v belt
If there is grease and other dirt left on the V-belt, because the dirt contains chemical substances, it can enter the Timing belt and destroy its material structure.
2. Excessive vibration amplitude
If the Timing belt twitches quickly due to machine vibration, the Timing belt will be severely damaged, thus reducing the service life.
3. Insufficient length
If the length is too short, exceeding its tensile strength, fracture behavior is inevitable.
4. Insufficient tension
If the tension is not enough, the friction force will also be insufficient, leading to slipping, increasing the wear of the belt and losing its ability to transmit load. The unstable transmission makes the belt transmission ineffective.
5. Unequal length
If the length of a row of belts is not equal, the amount of tension that each synchronous triangular belt bears will also be different, and some may experience slipping or excessive tension, causing belt wear. Therefore, when using it, it is necessary to choose a synchronous triangular belt with the same model.
Key points for using industrial belts
1. Strict Prevention of Staining: During use, it is necessary to strictly prevent the triangular industrial belt from being contaminated with oil and mud, and avoid contact with corrosive substances such as acids and alkalis to prevent slipping and corrosion of the triangular industrial belt, which may cause damage.
2. Installation: Before installation, if the center distance between the two axles is adjustable, the center distance should be shortened first, and the tape should be installed before adjusting the center distance as required; If the center distance between the two shafts is not adjustable, one triangular industrial belt can be inserted into the groove of one wheel first, and then the other pulley can be rotated to install the triangular belt. Use the same method to install the remaining triangular tape. It is prohibited to use tools to forcefully pry or pull the triangular industrial belt during installation to prevent stretching or damaging the triangular belt.
3. Suitable tightness: Triangle industrial belts that are too loose can easily slip, increase wear, and even cause poor power transmission; Being too tight not only causes. The V-shaped industrial belt is easily damaged due to elongation and deformation, and may also cause the engine main bearing and clutch bearing to be worn due to excessive force. The method to check the tightness of the tire is to apply a vertical pressure of about 2kg by hand in the middle of each tape, with a sinking amount of 20-30mm. If it is not suitable, it should be adjusted promptly.
4. Prevention of slotting: When installing pulleys, the centers of the two pulleys need to be aligned, otherwise it will cause the triangular industrial belt to work unilaterally and accelerate wear, shortening the service life of the triangular industrial belt.
5. Daily maintenance: When driving agricultural machinery, the operator should master the correct operating skills, follow the technical requirements of the user manual, and try to avoid sudden starting and sudden braking; Frequent overload operations should also be prevented; The triangular industrial belt should be removed and stored separately when the machine is out of use for a long time.
6. Mixing old and new belts: When replacing a group of two or more triangular industrial belts, the same model of triangular belt should be used, and the tightness of each group of triangular industrial belts should be consistent. It is not allowed to mix new and old belts or reduce the number of belts used. Otherwise, the force on the new and old triangular industrial belts will be uneven, and even the old triangular industrial belts will not work, affecting power transmission, Shorten the service life of triangular industrial belts.
7. Purchase: The triangular industrial belt selected according to the standard model should be compatible with the pulley groove, otherwise, the triangular belt will not work properly in the pulley groove. When replacing with triangular tape, bring the old tape to the agricultural machinery department to purchase to prevent the wrong model.
